“STONE AGE!!”

“SENKU!!”

“GEN!!”

“CHROME!!”

“RYUSUI!!”

“UKYO!!”

“STONE AGE!!”

The roar of the crowd was deafening. Their names echoed through the arena, fans yelling, singing, waving handmade flyers — a perfect storm of lights and music. It was the kind of chaos the band had mastered, perfecting it with every concert they performed. Tonight was their biggest show yet: the most songs, the most choreography, the largest audience. But despite the spectacle, something was shifting — quietly, from within.

Whisper all you can, the Echo Rebellion comes to getcha ...

The final verse of Echo Rebellion rang out as the stage lights dimmed. The five members slipped backstage while the crew prepped for the grand finale. The energy in the arena was electric; the fans knew what song was next — and they weren’t hiding their excitement. They screamed louder, waved their signs higher. Long ago this would be something the five would have enjoyed.

Once, the five would have fed off that joy. Tonight, their minds were elsewhere.

“Great job on the last song!” Suika beamed, handing out water bottles. Her voice cut through the tension like a little burst of sunshine. Gen gave her a tired but genuine smile — maybe the only one he could manage tonight. She was probably the one person he could smile at. He hasn’t spoken to Senku since their last fight. And it weighed on him more than he cared to admit. Gen wished their honeymoon phase didn’t disappear as soon as it started.

“We got five interviews after.” Minami revealed. Ukyo turned her out. He was tired of interviews, and answered the same questions again and again. Couldn’t they just relax — like they used to?

“Yuzuriha help here!” Chrome called her. He had torn his shirt but thankfully, Yuzuriha fixed it quickly and efficiently, like always. Every crew member rushes to get the stage and the band members ready for the grand finale. Everyone was stressed but tonight it was a different type of stress.

“We can’t make more changes!” Nikki argued.

“Come on, this’ll make it 10 billion percent more exhilarating.” Senku always wanted to make last-minute changes. Nikki couldn’t take it anymore. As the sound engineer, she knew very well there was no time. But Senku didn’t care.

Senku adjusted his earpiece, eyes distant, his mind anywhere but here. On the other side of the room, Gen drummed his fingers nervously against his green bracelet, stealing glances in Senku’s direction — though he didn’t expect him to look back. Not tonight. He and Senku had a tradition: drinking a bottle of cola before the grand finale. People thought it was stupid — but for them, it was something special. A ritual that made their bond stronger. Something they did at every concert, even before becoming partners.

But could a ritual fix what was broken? After all the chaos in the media… after what he did.

Could Senku forgive him?

“Can we pretend nothing happened?” Gen thought. He didn’t want to play that kind of mind games. He doesn’t want to lose the first person that saw through his games and tricks but maybe it's too late for that.

The room got even more chaotic, the crew members were preparing the final touches for the grand finale. Ukyo paced the edge of the room, his hands buried in the pockets of his loose jacket. Ryusui had told him to meet him there because he had something important to tell Ukyo but he never kept his promise. Instead Ryusui, as always, stood in the center of the room, confident and radiant, phone pressed to his ear, securing another deal. Ukyo watched him from behind.

Fame first. Everything else after. Something Ukyo knew that far too well. After all, it is the reason for him not to confess, the reason for him to hide his feelings for Ryusui. Because even if they became more than friends, Ryusui would leave Ukyo secondary and focus on fame. It had happened before, every time Ukyo was interrupted by a ringing phone and Ryusui always answered, leaving him behind.

Truly, what could he have expected from Ryusui this time? That he’d silence his phone? That he’d ignored the calls and paid attention to him? Still, Ukyo hoped this time would be different.

Can he still trust Ryusui? Even if Ryusui had told him exactly what he wanted to hear? Can he believe it?

How long he kept living in second place watching how fame stole Ryusui’s attention… from him.

“When would I… be a priority to you?” He thought, still watching Ryusui from behind. He tried to convince himself yet once more. “He still cares, right? He won’t leave me waiting again.” But hope won’t last forever.

As all this unfolded. Chrome watched them all from the sideline, heart sinking.

“Can I even fix this?” He had always been the one to keep peace inside the band, but now there’s nothing he could do. They hadn’t used to fight like this. But fame and time changed people for better or worse. The tension between them was more present than ever and Chrome didn't know how to fix it.

“No long faces! It's the grand finale!!” Kohaku shouted, trying to lift their spirits.

Chrome remembered how small they used to be. How they made each of their friends a member of the crew. How they used to enjoy each rehearsal. Back then, Chrome felt an electric, warm energy between them — a connection. But now, it was bitter. Cold. Annoying. Strange. Like he didn't know them anymore. Like they weren’t in sync anymore.

He had spent years calling them his family. Now, they felt like five strangers wearing the same uniform.

“Thirty seconds,” their manager, Francois, called.

“Senku-Chan let 's—“ Gen approached with two bottles of cola in hand.

Senku exhaled sharply. “Let’s just get this over with.” He walks away.

Gen’s chest tightened, his expression fell. “That’s all I am to you now? Something to ‘get over with’?” He left the two bottles of cola on the table — unopened. Untouched.

Ryusui finished his phone call. He met Ukyo half way to the backstage exit. Ukyo opened his mouth, finally ready to speak — But Ryusui walked right past him, ignoring him completely.

“He won’t even give me a chance to talk, huh?” At that moment, Ukyo finally accepted what he didn't want to admit.

“I waited for you… again” A small tear traveled down Ukyo’s cheek.

“Let’s go, gentlemen,” Ryusui grinned, oblivious to the tension. Too focused on fame to notice he’d broken yet another promise.

“Time to make history.” Ryusui snapped his fingers.

“Time to break apart.” Ukyo thought bitterly.

The five members grabbed their corresponding flag and made their way to the stage. It was time for the grand finale. Time to make history — But not the time to solve what was broken.

The lights rose. The crowd screamed. The stage erupted in color. Five silhouettes appeared against a backdrop of fire and sound — together in front of thousands, yet farther apart than ever before.

Banners of fictional nations unfurled above them, each symbol and flag tailored to represent their unique styles.

Sensō o sengen suru! We declare war!   They shouted in unison. The final song — the grand finale — had begun.  Senjō e yōkoso!

The music, the props, the choreography were none other than from their most iconic hit: Declaration of War. Better known as the song that has everything — a blend of Japanese and English lyrics, fast lines, quiet lines, rap battle, complex choreography, and more.

Keisan zumi da.   Senku waved his flag and led the opening verse — voice sharp, precise, powerful — but he never once glanced at Gen during their shared lines. Not even a little. Gen noticed he had altered one step in the choreography … Was Senku avoiding him?

Tell me, can you see the truth?   Gen’s voice was steady and his moves controlled, but his expression flickered every time his and Senku’s hands brushed in the choreography. They were supposed to lock eyes. They didn’t. Back then, Senku would give him a small but sincere smile — the kind that made Gen blush. There were no smiles. No blushes this time.

This is a declaration — war begins now!   The chorus hit hard. It felt real. Like a real war. Like they meant every word.

Moero! Moero! Flames in my blood, fire in my soul.   Chrome poured all his energy into his part, but even the crowd’s cheers couldn’t drown out the coldness between his friends. Maybe this is something he couldn’t fix.

I hit the target, silent night.   Ukyo’s part came. His voice was calm as always but his eyes betrayed him — tears had fallen.

Tomi mo meisei mo, subete ore no mono da!     Ryusui delivered a dazzling performance, as expected — or so they thought. He knew he’d skipped a few parts. He couldn’t meet Ukyo’s eyes. Not now.

You can’t fight what you can’t survive.   Chrome came to the front.

Calm like the sea, but sharper than steel.   Ukyo followed.

The stage shifted to give place to an intense rap battle between Chrome and Ukyo. It was electric — fast, aggressive, almost violent. It felt like a real fight.

When Ryusui and Ukyo had their joint verse, Ukyo skipped the planned hand-off and danced out of sync. Ryusui didn’t notice — or pretended not to.

Our voices rise, we all belong!   For the final chorus they stood side by side, but the space between them felt like a battlefield.

The last note and final drumbeat echoed through the arena. They turned their backs to the roaring crowd and walked offstage. Another successful concert — but with more cracks left unsolved.

The final note of Declaration of War still vibrated in their chests as they stepped backstage. Sweat clung to their skins. The fans’ cheers became a distant, muffled hum as the door to the backstage slammed shut behind them. Their manager and crew congratulated them but the five hadn’t said a word. The crew gave them some space.

For a few agonizing seconds, no one said a word. The tension between them grew even more. The atmosphere felt off. Wrong. Lost. After the awkward silence, Ryusui snapped — voice sharp and cutting through the tension.

“You didn’t follow the choreography, Senku.”

“So what? The crowd loved it.” Senku ripped out his earpiece, not even looking at him.

“That’s not the point.” Ryusui’s voice rose. “We had a plan. You broke formation. You always do what you want, and we just have to adjust." It wasn’t the first time Senku had made last-minute decisions without warning before.

“Maybe if the choreography didn’t waste time in useless flash, I wouldn’t have to fix it on the fly.” Senku shot back. Gen, Chrome and Ukyo stayed silent.

“Useless flash?” Ryusui’s eyes flared. His voice changed. “You think I spent weeks designing that for nothing? Maybe if you actually cared about the group instead of just playing genius, we’d be solid” He stepped closer to Senku.

“Says the one who’s more focused on fame.” Ukyo thought. He wanted to say it aloud. He didn’t.

“Oh please,” Senku scoffed, finally turning to face him. “This isn’t about the choreography. This is about you needing control.”

“Guys that’s enough.” Chrome stepped in, placing a hand on Senku's shoulder. This can be fixed. They just needed to talk. “Let’s talk this out.”

“Chrome-chan is right, let’s calm—” Gen stepped between Senku and Ryusui, trying to ease the tension. Ukyo watched from afar but no word was spoken yet.

“And you!” Ryusui’s finger shot towards Gen. “You blew this whole thing up the moment you sold your relationship to the press!”

“I didn’t—” Gen’s breath caught. Not knowing how to respond or if there was a correct answer.

“You didn’t what? Think? Or care?” Ryusui snarled. “You lit the fuse and now we’re all burning for it.”

“How ironic.” Ukyo thought. How ironic — coming from someone who would’ve done the exact same. He started to get annoyed because they weren’t focussed in the real issue.

“Leave him out of this.” Senku shoved Gen behind him and stepped toward Ryusui. Gen blinked in surprise by Senku’s attitude. Maybe Senku did still care.

“Oh, so you can drag us down but he’s off-limits? I didn’t know our leader had his favorites.” Ryusui barked a bitter laugh. Chrome tried again to intervene, but no one listened.

“I can fix it. There must be a way.” Chrome thought. But he was running out of ideas to try to solve what’s broken. “

Why are we even pretending this is about the choreography?” Ukyo, who had been quietly observing, finally spoke, voice cold. Everyone froze as a result of the sudden action. “None of us trust each other anymore.” His words hit like a slap because they were true. The truth they didn’t wanted to admit.

“Especially you,” Ukyo turned to Ryusui, eyes sharp as glass. “You’d rather answer your phone than face what’s in front of you.”

“What’s that supposed to mean?” Ryusui challenged.

“You know exactly what I mean.” Ukyo hissed, finally letting years of buried resentment surface. “There’s always a more important call. A more important stage. I’m tired of being in second place.” … “Tired of waiting for you” He thought.

Ryusui opened his mouth but no defense came out. He had been too focussed on fame to realize all the pain he had caused Ukyo. The pain he couldn’t erase … with a snap of his fingers.

“I’m sorry to interrupt but we should attend the interviews as scheduled.” Francois entered, unaware of what had unfolded.

“Francois, canceled them,” Ukyo said, turning to face their manager. “We won’t be doing interviews tonight.” How long had he wanted to say that? Say no to interviews.

“Understood Ukyo-sama.” Fortunately, Francois was someone who didn't ask much. A quick text to Minami would do the work. They pretended to leave the room but stayed nearby. Francois wasn’t like other managers — they actually cared about the band's physical and mental health. And fame without balance could ruin anyone. After all, they were still young and it is very complicated to have a healthy relationship with fame.

“Guys, please— we can fix this —” Chrome’s voice cracked as he tried to stop the collapse.

“No.” Senku said, his voice suddenly flat. Tired. Final. “We can't.”

His gaze swept over all of them — Gen’s trembling hands, Ukyo’s burning frustration, Chrome’s despair-filled eyes, Ryusui’s furious silence.

“We were good,” Senku said quietly, walking toward the door. “But we were never going to last.”

“Senku-chan, wait —” Gen reached out, desperation lacing his voice.

“You told the world about us, Gen. I let it slide. I thought I could handle it. But I can’t — not when I can’t even hold your hand without becoming someone else’s headline.” He paused, his eyes finally meeting Gen’s.

“You took the one thing that was mine.”

Senku's words froze him in place. Gen’s throat went dry. He wanted to say he didn’t mean to, that he just wanted to be honest about them, that he thought it was the right thing. But Senku was already gone.

The silence was suffocating. Senku didn’t look back as he left. Ukyo followed, his steps echoing behind Senku.

“Wait— Ukyo—” Ukyo stopped and turned as Ryusui called. But then, Ryusui’s phone buzzed in his pocket.

“Go ahead,” Ukyo said coldly, his eyes sharp as glass. “Answer it. That’s the one thing you never forget to do.” And with that, Ukyo was gone. Ryusui stared at his phone… and for the first time, he didn’t answer. Instead, he left it on a table and chased after him.

Gen, regaining his senses, ran after Senku. Surely those couldn’t be the only words between them tonight — not after everything.

And just like that, Chrome was left alone.

“Tea, Chrome-sama?” Francois appeared beside him, holding a warm cup.

“No thanks, Francois.” Chrome sank to the couch, hands gripping his hair. “This isn’t how we were supposed to end.” Francois said nothing. They just listened.

The stadium lights dimmed.

The echoes of the fans faded.

And just like that…

They were no longer a band.

And so began the years of silence.

But none of them had really let go.

That was the last time they stood on stage together…

Until now.

Chapter Text

“And with that, I concluded.” His fellow scientists applauded. Senku had just finished a presentation about his most recent research from the past year. A scientist's work is never over — there's always more to discover. As expected, Senku had become a well-known figure in the scientific world ever since Stone Age separated a few years ago.  

After the meeting, Senku packed his things and left the lab. Normally, he’d head straight home to get some sleep — but tonight, he had other plans. He was going to a Korean restaurant with Taiju and Yuzuriha. It had been a while since the last time they’d seen each other. Senku was a little excited, even though he pretended not to care. 

Instead of heading directly to the restaurant, he decided to stop by his home first and change out of his lab coat into something more casual.  

He put on his headphones and started his usual playlist as he walked to his apartment. He scrolled through his phone during the train ride, but nothing catched his attention — until he stumbled across a post from none other than Asagiri Gen. 

“Why do I still follow him?” He wondered, though the answer came to him faster than he wanted to admit. Because part of him never truly unfollowed.

That night — after the fight backstage — he and Gen talked privately about their relationship. They broke up on good terms … or at least that's what they tried to convince themselves. 

But even now, a single photo could make Senku’s chest tighten. 

Senku didn’t ignore the post completely. He saw it. Read it. Gave it a like. It was a picture of Gen on the stage where he would be presenting his mentalist show this week. In the picture Gen was smiling — his typical fake smile, the one he had mastered over the years. The caption was short and simple. Nothing glamorous. 

@Asagiri_Gen 14/6 — 7 PM. Ready for me to read your mind? 

Senku stared at the post for a few more seconds. A clinical, mechanical motion. Like observing data on a screen. But his eyes lingered too long on Gen’s smile. That damn fake smile he could still read like an open book.

He didn't have time to think about Gen. The past was the past. He didn’t care anymore. Or so he told himself. 

He slipped the phone back into his pocket and stepped off the train. The song on his playlist shifted to the next track.  

We were gold before the glitter — louder than the storm… 

He froze. The platform doors opened, but he didn’t move. 

Stardust Promise. Their debut. Their golden age. It had been a long time since he’d listened to it — but somehow, he still remembered every lyric. 

He didn't even remember keeping those songs in his playlist. Was it buried nostalgia — or denial too lazy to delete? 

He stared ahead as if the train window could answer that to him. The memories came faster than he could suppress them. The rehearsals, the arguments, the late-night breakthroughs. Gen humming half-finished lyrics beside him, smiling like he really meant it. A sweet, sincere smile. 

It wasn’t. Not to Senku. Not really. 

A loud noise echoed behind him, snapping him out of his thoughts. He almost missed his stop. His thumb hovered over the ‘Next’ button. He should skip it. He should move on.

But instead, he searched.

You pull equations from the air…

Scientific Mind Games started playing quietly through his headphones — the first duo song he had made with Gen. 

The first duet. The first time he let Gen inside the part of his brain he usually kept locked away—where formulas turned into metaphors and logic collided with music.

It wasn’t about Gen. It wasn’t.

It was a great song.

That was the only reason he listened. Or so he told himself.

He finally reached his apartment. Pulling out his keys, he stepped inside. Even after all this time, he had never moved out of Byakuya’s place. Technically, it had always been his, since Byakuya was always in space. Senku never saw a reason to leave.  

The apartment smelled the same. The faint hint of metal and old books.

Byakuya’s place. His place. The only space that hadn’t changed in years.

Everything else had. The band. The science of rhythm. Gen.

Senku stood for a moment before his bedroom door, the quiet pressing in harder than he expected. He used to come home to messages. To dumb texts from Chrome. To ambition ideas from Ryusui. To — surprisely — memes from Ukyo. To late-night songwriting sessions with Gen. Senku drummed his fingers against his purple bracelet. The bracelet he never took off. 

Now it was silent. He told himself he preferred it that way. More efficient. Less drama. Less distraction.

So why did it feel so damn empty?

He changed quickly into clean, casual clothes and headed out again. Yuzuriha had sent the locations days ago. The restaurant — called Korean BBQ — wasn't too far. About thirteen minutes by train, then another seven minutes walking. 

The train ride was uneventful, but Senku hadn’t expected to run into anyone. 

“Yo, Senku!!” A voice called out behind him as he stepped off the train. He turned, eyes narrowing slightly as Chrome jogged up to him, beaming like always. 

“Chrome,” Senku greeted as the other approached. Offering a nod more than a smile. “It's been a while.”  

“You missed me that much, huh?” Chrome grinned. "Even though we work in the same lab?” He slapped his back casually. 

“Barely. You're also a part-time producer,” Senku reminded him. “Some days, you don’t show at all because you’re off managing some idol group or mixing sounds for the next international hit. ” 

“A great producer, thank you very much.” Chrome said proudly, pointing both thumbs at himself. “Can’t help it if my genius is in high demand.”  

After Stone Age disbanded, Chrome couldn’t decide whether to be a scientist or a music producer — so he became both. Scientist by day, producer by night and vice-versa. Apparently, it was working out for him. The media had dubbed him ‘The Alchemist of Sound’ because every project he touched turned into an instant hit. His two most recent works — a comeback video for a major K-pop group and the debut single of a new duo — had both topped the global charts within a week.

Senku huffed a laugh under his breath. “You mean chaotic energy backed by dumb luck.”

“Same difference.” Chrome grinned. “Anyways, what are you doing here? This place is full of restaurants and fancy stuff. Are you on a date?” Chrome asked, looking around.

Senku hesitated. He could’ve deflected. Could've made some dry remark. But instead, he answered honestly. It was Chrome after all. 

“Not even close.” Senku let out a short, amused breath. “Meeting Taiju and Yuzuriha. Korean BBQ.” 

“You too?” Chrome blinked, then laughed. “I'm heading to the same place. Dinner with Francois.”

”Huh. Small world,” Senku said, eyes flicking away. 

And just like that, the weight in his chest crept back. Chrome’s energy was infectious, but it also made the quiet parts of Senku feel louder. Chrome had moved on. Thrived. Reinvented himself.

Senku?

He was still walking the same streets, wearing the same playlist, haunted by the same voice. 

“Senku?” 

“Senku!”

“You said something?” Senku was completely lost in thought. 

“You were spaced out.” Chrome observed. “I asked if Francois still visits you from time to time.” 

“They do.” He repaid, looking away. “Last time was about two weeks ago.” 

“It’s amazing, don't you think?” Chrome grinned. “Even though they’re not officially our manager anymore, they still make the effort to visit one of us every week.”

“It is.” Senku answered shortly. “Francois ended up managing Ryusui. Saw that coming. ”

“Everyone did,” Chrome turned to Senku. “Did you catch the last movie Ryusui starred in?”

“No, unfortunately.” 

“Man, it’s so good!” Chrome started. The way he talked, it sounded like an obsessed fan kid yapping about his favorite actor. “Ryusui definitely deserves the Oscar for best actor. You should watch it sometime — I’ll bring the snacks.”  

“I’ll think about it.” He replied quietly.

“You wished Ukyo a happy birthday, right?” Chrome asked, looking at him closely.  

“I did” Senku turned to meet Chrome’s gaze. 

“You better have. I even sent him a gift from you and you didn’t even thank me.” Chrome said dramatically, placing a hand on his chest like he was offended.  

Senku didn’t answer. “Ukyo still works there?” He asked, changing the subject. 

“Yeah. Still the marines' most efficient sonar operator, I’ve heard.” Chrome grinned. “He’s the only one of us who completely vanished from the public eye.”

The soft hum of conversations and the clatter of grilling meat filled the air as Senku and Chrome reached the restaurant. The warm scent of dazzling garlic and marinated beef hit them instantly. 

“You’re sure you’re not meeting with Francois at a five-stars fusion lab disguised as a café?” Senku raised a brow. 

“Even geniuses crave grilled pork belly, Senku.” Chrome grinned. 

Without waiting for more sarcasm, they walked in together. Inside, the restaurant buzzed with low chatter and sizzling grills. Senku spotted Taiju waving enthusiastically from a booth toward the back. 

“Yo! Senku!!” Taiju’s voice cut through the noise like a train whistle. 

“You made it!” Yuzuriha stood up slightly, giving a bright smile.

Senku gave a lazy wave and nodded to Chrome. His silent way of saying goodbye. 

“Francois isn’t here yet,” Chrome scanned the room. “Mind if I hang out with you guys until they arrive?” 

“Chrome!! Long time no see!!” Taiju’s eyes lit up. “Get over here!” Well, that answered his question.

Before Chrome could react, Taiju had already shuffled over to make room, dragging in an extra chair. Chrome sat with a chuckle, taking the spot beside Yuzuriha. 

“Didn’t expect a mini reunion tonight,” Chrome said, making himself comfortable. “We just need someone to start singing and we've got a flashback episode.”

“Don’t tempt him.” Senku muttered, pulling the manu toward him.

“So? What’s everyone been up to?” Taiju grinned while passing an entrance plate to Senku. 

“Saving the world one equation at the time,” Senku replied without looking up. He grabbed some food. 

Yuzuriha leaned forward. She offered some appetizers to Chrome. “And you, Chrome? Still balancing chemistry and music production?” 

“Of course. I sleep twice a week and cry into my synthesizer” Chrome winked. He grabbed some appetizers. “ No complaints, though. My last two projects topped the charts.” 

“He’s being humble,” Senku said flatly. “He got an award-nominated duo and a comeback single that broke servers.” 

“Aren’t we all legends in our own way?” Chrome shrugged like he couldn’t help being brilliant. “ You have your own fashion line now, right Yuzuriha?”

“Yeah… I didn't expect it to take off so well.” She blushed a little. 

“What you’re talking about! It is the best fashion brand in the country — no, the continent — no, the world!” Taiju defended her. 

“Taiju, you're still at construction work?” Chrome asked. 

“Yup.” Taiju responded, simple as ever.

As the grill at the center of the table heated up, they fell into easy conversation. Yuzuriha handed out chopsticks and helped set the small side dishes in their proper place — she always had a natural grace about her, even with something as simple as folding napkins.

Senku leaned back a little, letting the familiarity soak in. There was something oddly grounding about being surrounded by these people — no expectations, no spotlight, no interviews. Just voices overlapping, meat sizzling, and the quiet knowledge that they used to be something together.

“By the way,” Chrome leaned his elbows on the table. “Have you seen Gen lately?” 

The table was silent for a beat too long. Yuzuriha and Taiju glanced at Senku.

“I saw a post,” Senku said casually, eyes on the grill. “That's all.” 

Chrome didn’t push, but a flicker of understanding crossed his face. “He’s got a show this week. Big venue.” 

“I know.” 

The tension started to grow. Old unresolved issues started to be relevant once more. But before the conversation could dig further, Yuzuriha clapped his hands.

 “Alright, alright! I say we make this night about food, not feelings.”

“Agreed. Let’s enjoy this while we can!” Taiju laughed. 

“Anyways look at what Suika made!” Yuzuriha introduced a new topic quickly. “She made Kaseki an Instagram account to show his crafts.” 

Yuzuriha pulled out her phone and showed them a video that Kaseki — with Suika’s help — had posted recently. “Suika told me they’ve gained a lot of followers, even though they just started posting.” 

“A new follower now!” Chrome quickly pulled out his phone and opened Instagram. “What’s the username?” 

“Old.man.of.steel — with a dot between each word.” Yuzuriha replied quickly. 

“If you’re sharing that, you have to give me Suika’s account too!” Chrome said, half-joking, half-serious. “Wait, she has one now?”

“Of course she does! She’s grown up so much.” Yuzuriha smiled. “She’ll be turning seventeenth in a few months.” 

“Seventeen?!” Chrome went mind-blowing. “Kids grow up so fast nowadays.” 

“Yeah, anyway Suika’s username is backstage.kid. You're welcome!” Yuzuriha added, sending it to him. 

The mood had changed and the tension was gone, at least for now. As they dug in, an elegant figure approached the table. They turned to face everyone at the table and gave a subtle bow to the group. 

“Good evening. I hope I’m not interrupting.” Francois had arrived, dressed in a sleek charcoal vest with crimson tie that matched their ever-immaculate presentation. 

“Not at all,” Yuzuriha said warmly, welcoming Francois “It's good to see you again.” 

“Likewise. Neither of you have aged a day.” Francois replied with effortless charm. 

“We should be going,” Chrome said standing. “Thanks for the appetizers and good vibes. It was great to see you all. I’ll catch you all later.” 

“You should visit my place sometime.” Yuzuriha invited them excitedly. “Suika would love to see you! Francois you too.”

“I’ll let you know when I’m coming!” Chrome accepted the invitation happily. 

“Thank you, Yuzuriha-sama. It was great to see you again.” Francois gave a small bow before the two disappeared into the crowd. 

“You should come to the studio sometime.” Chrome called Senku as he left. “We’re cooking up something interesting.”

“We’ll see.” Senku replied with a faint nod,

And with that, Chrome and Francois were gone, leaving behind a faint electric energy in his wake — the kind that always made Senku wonder if he was about to be pulled into something much bigger than he expected. The table felt just a little quitter after Chrome slipped away. 

Senku reached for his glass of water, keeping his expression neutral — too neutral, Taiju and Yuzuriha shared worried glances. 

“You are okay?” She slipped her tea slowly, eyes flicking to Senku’s face. 

“Did I seem not okay?” Senku didn’t look up. 

“You got quiet after Chrome mentioned Gen.” Taiju said with a soft nod.

“He’s just my ex. Not exactly breaking news.” Senku took a deliberate bite of his meat, chewing like the topic bored him. 

Yuzuriha didn’t say anything more. Her fingers played with the edge of her napkin. She glanced at Taiju. He nodded like he knew exactly what Yuzuriha wanted to tell him. 

“Senku… it’s okay if it still bugs you.” Taiju said, ribbing the back of his neck, clearly crossing his words. “You don’t have to act like—”

“I’m not acting,” Senku cut in, voice steady. “It’s in the past. I’ve got my work, my research, and more than enough going on without digging up ancient history.” 

His chopsticks clicked sharply against the plate as he picked up another piece. Taiju and Yuzuriha exchanged another look — brief, but full of quiet understanding. They know him too well to argue. They also know him well enough to let it go... for now. 

“Did you ever finish that AI-guided microscope prototype?” Yuzuriha smiled gently, yet again she managed to change the topic quickly. 

Senku’s expression relaxed a fraction, the sharp edge softening. And just like that, the moment passed. The three of them eased back into conversation — about research, travel plans, and Yuzuriha’s upcoming exhibition. But the topic of Gen still lingered, quietly, between the lines.

— 

Meanwhile Chrome and Francois followed the host to their reserved table. A cozy table near the window. The restaurant’s warm lighting gave the space a welcoming, intimate glow. Once seated, Francois folded their napkin with careful precision. 

“I hope I haven’t kept you waiting too long.” Francois stared, voice calm as always. 

“Not at all. It was good to see them again.” Chrome smiled but faded quickly. “Thought, I got things… tense for a sec. Gen came up." He rubbed the back of his neck nervously.  

“I see.” Francois replied quietly. “The past is never easy to forget but it’s essential for growth.” They always knew what to say.

“So, whose turn was it last week? Ryusui?” Chrome leaned forward with a grin, setting down his menu. 

“Gen-sama, actually,” Francois said. “He insisted on picking the place. We ended up somewhere with velvet curtains and a ridiculous chandelier.” 

“Of course you did.” Chrome chucked. 

“He also made a point to tell me — quite dramatically — that I was a far better manager that the one he currently has.” Francois let out a soft laugh. 

“Classic Gen,” Chrome said, shaking his head fondly. “Throwing compliments like draggers.” A waiter arrived with their drinks. 

“He did seem … distracted, though.” Francois added, slipping their tea. “He didn’t say it aloud, but I could tell. His thoughts were elsewhere.” 

Chrome gave a thoughtful hum but didn’t say more. Francois didn’t push. 

“You still rotate us like we’re on a schedule.” Chrome looked up after a moment.

“I do,” Francois confirmed. “Dinner with each of you. every few weeks. It’s more than routine, Chrome-sama. You may not be my clients anymore, but you were — and still are — important to me. That doesn’t vanish just because roles changed.”

“You know,” Chrome smiled, softer this time. “The world may call Senku the brains, Gen the face, Ryusui the visioner, Ukyo the silent heart and me the wildcard and heart of Stone Age. But honestly? You were the glue.” 

Francois didn’t respond with words. They simply placed a hand briefly over Chrome’s, a gesture full of quiet understanding.

“Ready to order?” Francois asked, withdrawing their hand.

“Yeah.” Chrome responded quickly. Francois raised his hand to call the waiter. 

“So,” Francois smoothly, withdrawing their hand, “How has your week been, Alchemist of Sound?

Chrome grinned. “Busy. But I guess that’s how I like it.”

—

Elsewhere, the city’s nose faded as Gen stepped into his apartment. Yet another day of being a performing — pretending. He was so tired that, after kicking off his shoes, he collapsed onto his coach. 

“My, finally a break.” Gen said quietly, letting out a long sigh. He stretched like a cat wanting to finally have relief. The elegant suit he was wearing he didn’t take it off. 

The silence was suffocating him along with the memories. The memories from a time he didn’t have to be a walking performance all the time. But everything has changed since then. No Chrome cracking open soda cans. No Ryusui shooting out choreography ideas. No Ukyo’s quiet, grounding conversations. No Senku hunched over lyrics, arguing they weren’t ‘scientifically accurate’. 

He chuckled to himself at the memory. Maybe the only chuckle he gave today. His phone buzzed. He didn’t need to check to know who it was. Still, he looked — hoping it was someone else.

It wasn’t.

His manager. Again. 

“Francois-chan was by far a better manager than you!” Gen thought bitterly as he stared at the screen. 

Then he focused on his wrist. 

The green bracelet.

He never took off. 

“Did I really let the only person who saw through me walk away so easily?”

The only thing that had ever felt real. 

Nostalgia — his worst enemy — had attacked yet once more. 

Memories of the band. Of everyone. 

Of Senku. 

Their late-night talks. Their chaotic songwriting sessions. The way they understood each other with just a glance. The silence they shared — the kind that felt like home.   

Gen drummed his fingers against the bracelet. 

He hated himself for what happened that night — when he made their relationship public without Senku’s consent. Even after now, he couldn’t forgive himself. 

If the media hadn't killed him, the memories surely would. 

“We were supposed to build the future together… weren’t we, Senku-chan?” A tear slid down his cheek. Then another. 

—

From his luxury penthouse at the center of the city. Ryusui started out at the breathtalking skyline. Or at least, he pretended to. The filming of a brand new movie he starred in had wrapped early, so he was home sooner than usual. 

He picked a snack from the care package Francois had left for him and reread the handwritten note inside. 

“You were stunning, as always. Dinner next week? Already scheduled. PS: Having dinner with Chrome tonight.”  

Ryusui smirked — until he glanced at his phone.  

Ukyo: Seen

Another message left on read. 

He tossed the device on his couch with an exasperated sigh. All around him were the trappings of success — awards, scripts, custom suits, city views… but none of it filled the quiet.

He has everything.

But at what cost?  

He scrolled up through their old texts:

Ryusui: Hey, you’d love this view. Reminds me of the night before our first concert. Remember the chaos backstage?

Ryusui: Just saw a documentary on deep-sea sonar mapping. Thoughts of you. You always explained that stuff better than the scientists. 

Ryusui: I know I messed up. I should’ve made time for you. For us. 

Ryusui: Give me a chance. Please. 

All of them — read. No reply. 

Ryusui leaned back and covered his face with his hand. 

People adored him, praised him — but the one person he wanted to reach wouldn’t even say hello. Not anymore. And he deserved that. 

When Stone Age was together, he’d been too focused on the spotlight — chasing interviews, adoration, chasing fame — leaving Ukyo in the wings. 

Quiet, reliable, brilliant Ukyo.

Who waited. Waited for him.

 Until he didn’t.  

He stared at the ceiling. 

Could he even fix what he broke? 

— 

The lab was quiet now, lit only by the soft glow of computer monitors in standby mode. Ukyo’s shift had just ended. He sat in the breakroom alone, sipping lukewarm tea. The faint hum of the sonar still echoed faintly in his ears. 

His phone buzzed. 

Another message from Ryusui. 

He didn’t open it. He didn’t need to. 

He already knew the tone — half-regret, half-hope. Ryusui had a way of turning apologies into invitations.

Ukyo clenched the phone tighter, then placed it face-down on the table. 

“I can’t do this again." He thought.

He told himself he was over it. Over him. Over music. But sometimes, in the sonar room, a certain rhythm would come though the monitors and his fingers would twitch in the time with it.

The echoes of old harmonies. 

The ones they wrote together. 

The ones Ryusui used to sing like he meant every word — even when he didn’t. 

Ukyo took a deep breath. 

There was a reason he hadn't deleted the messages.

 A reason he hadn’t blocked Ryusui. 

But he wasn’t ready. 

Maybe not ever. 

—

The meal arrived — grilled beef, sizzling platters and a dozen side dishes — but for a few minutes. Chrome and Francois ate in a comfortable silence. The kind that only came with years of shared history.

“You seem unusually thoughtful tonight.” Francois was the first to speak. He noticed Chrome was quieter than usual, more reflective. 

Chrome doesn’t answer right away, clearly choosing his words with care. 

“I saw a poster the other day.” Chrome finally began, his voice soft. He chuckled lightly, setting his chopsticks down. “For this year’s Marine Safety and Scientific Education Charity Gala.” 

 “Already? That's still two months away.” Francois looked up, curious.

 “I know,” Chrome said. “But seeing it caught me off guard. I just… got hit with a wave of nostalgia. That was where we had our first public performance as Stone Age.” 

“A night of beautiful chaos.” Francois nodded slowly, a smile pulling at their lips. 

“Exactly.” Chrome laughed. “Taiju nearly tripped over the speaker cables. Gen was freaking out because his mic wasn’t where he left it. Ukyo was overwhelmed by the noise. Ryusui failed the first move in the choreography he made. And Senku… man, he kept pretending he wasn’t;t nervous, then cracked his voice in the first verse.” 

“And yet, the crowd loved it. Every second.” Francois laughed softly. 

“They did,” Chrome said, quieter now. “It was the first time we felt like an actual boy band. Like we could be something.” 

“You know, it’s kind of funny.” He glanced at Francois. “That night wasn’t just our debut. It was yours too.” 

Francois tilted their head slightly.

“You became our manager right after that show.” Chrome reminded. “Before that, we just knew you as Ryusui’s super-butler — the one who could do anything.”

“Yes,” Francois said with a smile. “I believe Gen said something like: ‘Who knew a fancy butler could run a team better than every manager in the industry?’”

“That sounds so Gen.” Chrome grinned. “And he was right.”

”You all needed someone who saw more than the business side of things.” Francois replied, their expression softening. 

“And, you gave us more than that.” Chrome said. “Structure. Trust. Real belief.” 

“And what about you?” Francois took a sip of their tea. “What did the gala give you, Chrome-sama?” 

He remained quiet. Chrome hesitated — just for a second — then said. 

 “Purpose.” 

A pause followed.Not awkward — just full.

Then Chrome spoke again. “I was thinking… what if we did it again? Just for one night. Not a full comeback — not unless everyone wants it. But… for old time’s sake.” 

“An ambitious idea.” Francois didn’t look surprised. 

“You’re not shooting it down.” 

“I’m not,” Francois said. “Because I’ve thought about it too. And not as your manager — not anymore— but as someone who cares deeply about you all… I believe the world would welcome a reunion. Even if it’s only for a moment.” 

“Then I better start preparing my best persuasive arguments.” Chrome leaned forward, his expression brightening. “Let’s see if the others are down for some old time’s sake.” 

“Then let's see where this moment leads.” Francois raised their glass. 

Their glasses clinked — a quiet toast to a possible beginning. 

An idea born from nostalgia.

An opportunity to fix what was broken. 

A chance to make things different this time. 

But whether or not it would succeed… no one could say.

After all, some scars are too deep to heal in just one night. 

And some wounds? 

Some wounds can open again.

Chapter Text

“No.” Senku interrupted, returning his focus to his ongoing project. “I don’t have time to dig up ancient history.”  

“Come on, Senku!” Chrome protested. “One concert. It’s marine safety and science education, literally your two favorite things mix up!” He isn’t sure if Senku is into marine safety but he must try everything he has to convince him. 

Chrome had spent the last few days preparing his best persuasive arguments and puppy faces to convince everyone to come back for one last concert. Turns out it would be way harder than he thought. He thought starring up with Senku was the best choice since it would be really difficult to convince him but if he did convince him the rest would be a piece of cake. 

Senku didn’t respond — or he didn’t intend to. His hands moved fast and efficiently on the circuit trying to keep himself busy. Ignoring Chrome was easy — his mind was another story. 

“Senku, you can act all emotionless and careless,” Chrome began, he moved to Senku’s side trying to get his attention one way or another. “But deep down you want to. It’s true we had a bitter separation but things have changed. We have changed. A chance to make things different this time.” 

Without expecting a response,  Chrome began his way out of Senku’s lab. Not trying to insist more — at least for today. Senku stopped working on his mechanism but he didn't look at Chrome directly, preferring not to look at him. 

“Think about it, Senku.” Chrome stopped at the edge of the door looking back inside before leaving Senku in the room alone. 

Without Chrome’s presence, Senku resumed his work. The room turned silent, the kind of silence he’s used to but this time it hit him hard. His mind and thoughts were elsewhere to the point when he was working only to keep his mind busy avoiding the topic.  

“Why am I even considering it?” He stopped working. Turning to look around the room and at his work. This is weird in him, thinking of something that isn’t science. Thinking about the past — when he’s always moving forward. 

His eyes focused on the ceiling like he was looking at the stars he always had admired instead of a white plain ceiling.  

“But we have changed.” Chrome’s words echoed in his mind but especially that part. He found it hard to believed it. 

Senku chuckles bitterly. Everything around him had changed — everything but him. He is still the same science maniac, the one who can’t even move on from his past…  and from a certain mentalist. That made it weirder. He, the man who only has eyes for science and always moving forward, is being torn apart by his past feelings? 

“This is stupid.”  A brief but loud thought. Senku touched his bracelet softly. How can someone like him be like this?  Is it allowed for someone like him to be tortured by emotions?

— 

Some time later, Chrome hoped that his words had at least convinced Senku a little. He plans to try again later this week. 

He took out his phone as he exited the lab — June 14th, current time 8pm. He was running late. He hurried to his car and started to drive.    

He was on his way to convince the next person: Gen. Chrome is very confident, convincing Gen would be a little easier than Senku but he can’t let his guard down. After all, he's dealing with a mentalist. His phone buzzed, a new text. He read it quickly. 

Francois: The show is almost over. I’m waiting at the parking lot.

Chrome would have to thank Francois later. After all, Francois had moved some strings so that he could meet with Gen tonight right after his show was over.  Recently, he was told the well known Asagiri Gen had a busy agenda everyday so this may be his only opportunity to talk to him without interfering with his busy schedule — Chrome won’t let pass this opportunity. Earlier that day, he sent Gen a quick message just to let him know in advance he would arrive.  

As he approached a fancy theater surrounded by light everywhere and people in elegant clothes leaving the theater though those tall doors with golden borders. He parked his car and quickly spotted an elegant figure waiting for him not so far away from the main event. 

As Chrome got out of his car, Francois approached to greet him before walking down an alley toward the backstage door. Even the backstage door was well decorated as the main doors. They walk through the door and they enter a new world. 

Chrome had thought for a long time a theater backstage was very different from a concert backstage —  turns out he was mistaken. It was as chaotic as the average concert backstage. 

Back then, when Stone Age performance was over, the backstage was a total chaos of celebration and organizing everything they had used during their concert. Back then, they would help organize the cables and stuff even though they were exhausted from the concert they gave.

They stopped at a black door that had a white sign pasted with the name Asagiri Gen on it. Francois excused themselves saying they had programmed a serious and important conversation with Gen’s manager. Chrome could only chuckled, wishing that man good luck dealing with Francois. He hopes Gen’s manager doesn’t quit after this.  

Chrome watched how Francois lost themselves through the long well decorated hallways leaving him alone to deal with an infamous mentalist. Nostalgia hit him right before he had the time to even knock the door. 

He had so many fun and serious memories that Gen was included. Although his favorite has to be that time when Gen, along with Senku, swore that their last duo song — N.A.S.A. — wasn’t a love song disguised with scientific lyrics. He laughs at the memory, even after all this time neither the scientist nor the mentalist had revealed a soul, what’s the true meaning of N.A.S.A. 

He could keep on and on remembering every moment they lived during those years. But right now Chrome has work to get done. 

Knock. Knock. Knock. 

He knocked the door three times following a certain rhythm. 

“Come in!” Chrome didn’t wait long for an answer. As a cheerful charismatic voice was heard from inside. 

The inside of the dressing room had nothing special. It had the same stuff any dressing room would have — a small couch, a snack table, courtesy gifts and space for whatever outfit needed it.  

“My, my, hello again, Chrome-chan.” A man with black and white hair turned around to face him instead of the mirror with lightbulbs all around that was behind him. 

“I would say the same. Good to see you again Gen.” The mentalist smiled and made a small gesture asking Chrome to sit on the couch. “Congrats on tonight's show. You were dazzling as always.” Chrome congratulated him.

“That goes to you too. Already one of Japan’s greatest producers.” He responded, laughing a little. Chrome isn’t sure how to introduce the reunion topic. 

"If the greeting is over.” Gen spoke, his tone more serious than before. “ Say, what brought you here tonight, Chrome-chan? I don’t think you came all the way to my dressing room only to say hi.”

Classic Gen. Always discovering someone's true intentions. Something Chrome appreciates. Fortunely this would be easier than he thought. 

With his thoughts organized, he took a deep breath and began to speak. 

“Do you remember the charity gala Stone Age used to present every year?” Chrome began casually, trying his best not to look nervous or desperate. 

“Of course I remember.” His voice was sharp and precise. It felt like Gen was analyzing him in full detail. “The golden years.” 

The Golden Years. The headline that the media used to refer to them during their peak era. In short,  no one expected Stone Age to separate during their prime era. The headlines were the same for months. Only one topic was discussed: their separation. 

“I’ll be direct.” Chrome passed Gen a sign of the Charity Gala event. The same sign he had told Francois. Gen accepted without saying much and gave it a quick look.

“Just say what you practice.” He told himself. Chrome made himself a full script in his mind and  practiced unnumbered times what he would say in order to convince Gen. 

“Gen, it's time to bring back the magic, literally.” What he said hooked Gen immediately, paying close attention to Chrome. “Let’s reunite for a last concert. For the kids, science and old times sake. One night only.” 

The black and white hair man remained quiet. His usual smile faded. Thinking he may reject. Chrome quickly speaks, giving solid arguments. He told every single argument he had been practicing for days, every sentence more structured than the last one.

And Gen … could only laugh. 

The kind of laughter that was sincere, not faked. Although Chrome couldn’t tell which is which.

“Chrome-chan, you do know how to tempt a mentalist.” The man's expression shifted once again. This time to a white expression Chrome couldn’t find a meaning to it. “I say your idea is ambitious but yet possible but…” 

Suddenly, he stopped. 

Chrome noticed a nervous tone toward the last words Gen spoke but he decided not to push him. After all, Gen had never let his walls down to no one or so Chrome though. 

“Nevermind, just answer me a question.” Gen spoke, voice control and calm. Chrome just nodded prepared to answer whatever question Gen had. Although he didn’t expect what he was about to hear. 

“Does this involve Senku?” He asked while playing with his bracelet, not even trying to make eye contact with the person next to him. His tone was serious since he didn’t refer to the scientist as ‘Senku-chan’ but used only  his name instead

“Why am I asking if supposedly I don’t care anymore?” That thought invaded his mind causing him to think making that question was ridiculous when he had proclaimed himself ‘the shallowest man on Earth’ uncountable times. 

Everything he had done was only for his benefit and nothing more, right? 

In the past, he accepted to be part of Stone Age only for the fame it could give him.  He saw the opportunity to make his name known so he took it. The mentalist never minded anything else that didn't benefit him or so he always said. 

“It was nonsense to ask that anyways—”

“Senku is in, I’m sure of it.” Chrome said without hesitating.Without thinking. It wasn’t a supposition or facts but a statement. 

Then silence came in. Although it wasn’t for long. After Gen took some deep breaths, he spoke once again. 

“Then count on me! Let’s make real illusions!” Gen smiled but not his typical fake smile. Although Chrome still doesn’t know the difference. 

“Hell yeah! Then I’ll notify you when we’re having the meeting to organize some logistics.” Chrome said enthusiastically. Turns out, he did a fantastic job convincing Gen but it was hard to believe. 

“I’m looking forward to it!” Gen said while he waved at  Chrome who left his dressing room. 

Right after Chrome left, Gen's expression shifted drastically focusing once again on his wrist — on the green bracelet. 

“I promised I’ll make things right this time.” Gen couldn’t focus on anything else that wasn’t the bracelet on his wrist. His heart was beating faster than usual — the same speed it beat once before. “I’ll apologize properly this time.” 

—

“HA HA! You can count on me!” The sound of fingers snapping was heard. As the greediest man alive accepted his idea without hesitating a second. It was no surprise that Ryusui would be the easiest to persuade, after all he couldn't deny a good offer. 

“Everything went well, Chrome-sama.” Francois said as they entered Ryusui’s trailer. Due to his participation in a new original film. Francois, once again, had moved some strings so Chrome could meet with Ryusui during his break time during filming. The trailer itself wasn’t that fancy but fancy enough for the standards of Ryusui’s desire. 

“Francois, add Stone Age reunion to my schedule.” 

“I already did it, Ryusui-sama” Efficient as always. 

Things turned out better than Chrome thought initially, although he still had to deal with persuading one more person — not counting Senku, he would deal with him later. 

“I better get going!” While he was standing from the couch. Francois stopped right before Chrome could make it to the door. Chrome didn’t take long to realize what was happening instead he turned to face the blonde who was walking towards him.

“The world has been waiting.” Ryusui started, his desire can be seen through his brown eyes. “But tell me…”

Ryusui made a rough pause. It felt like he was thinking about each world wisely, taking more time than he usually does. Instead of talking with his usual ‘I want it’ tone he used a more controlled one. Chrome had a small feeling of knowing what Ryusui was going to ask him but he preferred to not rush him and let him take his time. After all, waiting gave him better results than rushing someone. Some of the manipulation and persuasion lessons he had learned long ago from  a certain mentalist. Guess they were useful after all. 

“Have you asked him?” He finally said. His face wasn’t his confident expression but a more serious one. 

“I knew it.” Chrome thinks briefly. He quickly realized who they were talking about. After all he predicted it was about a certain sonar boy. 

“Not yet.” It would be nonsense to lie about it. Chrome knew really well convincing Ukyo would be even harder than memorizing and reciting every digit of Pi. The few times he hung out with Ukyo. The white hair man had left it extremely clear he didn't have any interest in music anymore or a reason to do it again. 

It would be an extremely hard challenge. 

“How do you plan to convince him?” The blonde asks bitterly.

”I was thinking of convincing him by telling him how the Gala would improve marine safety or something like that.” He answered without hesitating a little. After all that was the only way he saw to effectively convince Ukyo to join for one more performance. That and a lot of luck. 

“Don't worry Chrome. I would be the one to convince him.” Ryusui stated proudly as he snapped his fingers once again. 

Chrome was about to open his mouth to protest but he closed before saying anything. No one is able to change Ryusui's opinion when he has already decided — something Chrome knew well enough. So he didn’t have any other option than to agree. 

“Well then, I’ll leave Ukyo to you!” He said it enthusiastically while smiling. “You can ask Francois for details. Text me after you talk to him!” Just like that Chrome leaves. 

Somehow he managed to keep hidden how worried he was about this. It wasn’t a secret that Ukyo and Ryusui had an unresolved history. There are so many possibilities and variables that can go terribly wrong. 

The worst — and most probable — scenario being that Ukyo rejected coming back. Right now, Chrome plans on returning to his apartment to work on how to convince Ukyo assuming that Ryusui fails. 

Ping. Click. Ping. 

The buzzing from his phone in his pocket took him out of his thoughts. He had a new text. He quickly unlocked his phone, expecting to be a new project offer he may be interested in or something. But instead he froze at seeing who had sent it and was shocked when he read it. 

The message wasn’t from a new project needing his amazing production. 

But it was from Senku.  

Senku: I’m in for one last concert. 

Short. Precise. Direct. Was everything Chrome needed to get excited. “Let’s  go!!” He didn’t care if people were looking at him like a weirdo. 

Stone Age was almost complete. The brain, the face, the wildcard and heart, and the vision were in. 

Only missing the silent heart.

The echo. 

Right now, the only thing he could is wishing Ryusui luck. 

—

The sonar pinged steadily, a soft, repetitive pulse cutting through the quiet of the room. 

Ukyo sat at his console, eyes locked on the screen, headphones snug over his ears. His fingers danced across the controls — focused, practiced, detached. His shift was nearly over, but his mind checked out hours ago. To this point his mind was elsewhere. Even the sea felt quiet tonight. 

Ping. Click. Ping.

He blinked slowly. 

Then, a soft buzz in his pocket. 

He had a feeling of what it could be. So, without changing expression, he slipped one hand into his coat and checked his phone. A new text from a certain navigator, what a surprise. He doubted before opening it but still opened it. He planned to leave it on read anyways. 

Ryusui: Ukyo!! How are you doing? 

Ryusui: I’ll be direct. Chrome says we should get Stone Age back together. Just one night. Charity gig. You in?

Ukyo stared at the message. 

Of course it was Ryusui sending it. He could see the same ego, the same recklessness, the same charm wrapped in a sentence like it was no big deal. Like time hadn’t passed. Like nothing had happened. 

Ukyo locked his phone without replying. 

“I don’t care about music anymore.” He thought. That was what he told himself countless times. What he told others. What he believed — until moments like this.

Maybe Ryusui didn’t change a bit during all this time but he did. He won’t let himself wait again for someone who never made time for him in the first place. 

The buzzing returned. Another message. It wasn’t a secret how insistent Ryusui could be sometimes. 

Ryusui: It was Chrome’s idea. Swear on it. 

Ryusui: Don’t ignore me like you did on your birthday, sonar boy. 

He could have ignored him but instead he scrolled up to that old text. The one from his birthday. The one Ryusui sent after he wished him a happy birthday. 

Ryusui: Dinner’s on me tonight. I promise no press, no pitch, just you and me. Say yes for once. 

As always, Ukyo had left him on read. Now he stared at the message longer than he meant to. 

His shift ended with a final sonar ping. He stood up, hung his headphones neatly, and slipped his jacket on. Outside, the air was crisp. Quiet. Ukyo walked toward the exit, his thoughts still tangled around the text he received, Chrome’s name, the idea of a reunion, and — 

“Yo, sonar boy!” A voice called him from behind. 

Ukyo stopped in his tracks. His hand had barely touched the door handle. “He came here. Of course he did.” He turned to see the last person he wanted to see approached towards him. Ukyo’s face didn’t change, but inside, surprise flickered. 

“Stalking me now?” He asked flatly, his hands still in his pockets. 

“Couldn’t risk you ghosting me again.” Ryusui pushed off the raid with a shrug. “Text is too easy to ignore. This time I needed you to hear me out!”

“And what, you thought showing up here would change my mind?” Ukyo looked at him, eyes sharp. Tired. Guarded. His voice came dead and flat — wasn’t his usual soft tone. 

“No. I thought seeing my face would remind you of everything we used to be.” Ryusui stepped closer but not closer enough to invade Ukyo’s personal space. “Of what we could still be even if it's just for one night.”

Ukyo said nothing. His silence spoke volumes. 

“I know you said you don’t care about music anymore. But I don’t buy it.” Ryusui’s voice softened. “Not from the guy who used to stay hours after rehearsal just to get one harmony perfect.” 

A beat passed. 

“That was a long time ago.” Ukyo looked away, like he was remembering those times. The streetlamps cast long shadows behind them. 

“Yeah. But some things aren’t as far as they feel.” Ryusui nodded. 

The silence between them grew heavy, but it wasn’t empty. It was full of all the things Ukyo hadn’t said, and everything Ryusui hoped he still felt. 

“It’s one night.” Ryusui added gently. “For Chrome. For them. For us, if you’ll let it.” 

“You’re really not going to let this go, huh.” Ukyo exhaled slowly. The cold fogged his breath. 

“Of course not.” Ryusui smiled. 

Ukyo didn’t smile back. But he didn’t walk away, either. 

Silent invade them. It’s in moments like this Ryusui wished he didn’t screw their relationship back then. Even if they never officially became partners. He regrets every time he left Ukyo waiting for him. Every empty promise he had told Ukyo back then.

Ryusui desired everything but he couldn’t have what he desired the most. 

Ukyo leaned against the railing now, mirroring Ryusui’s earlier posture. He didn't look at him when he spoke.

“If I agree… it’s just one performance.” Ukyo started after the silence. His voice was quiet, deliberated. “No tours. No media. No album talk.”

“Got it. Just the charity gig.” Ryusui gave a small nod. He saw that coming so he wasn’t surprised. Ukyo has always been the guy who keeps his private life a secret — along with Senku. 

“And one more thing.” Ukyo turned to him sharply. Eyes sharp as glass. Ryusui raised an eyebrow, but said nothing. 

“If you start acting like you used to.” Ukyo’s tone sharpened, colder now — not angry, just clear. “Chasing every camera, every deal, ignoring everyone around you…” 

He paused, locking eyes with Ryusui for the first time. 

“I’m out, I won't stick around for that again.” 

Ryusui’s grin faded. The air got still. For a moment, it wasn’t just about music but about something deeper, something that had hurt before. 

“I hear you.”  Ryusui spoke quietly. “ You have my word.”

Ukyo nodded once. No smile, no warmth, but no storm either. Just a silent agreement.

”I’ll join the rehearsals.” Ukyo added, softer now while he looked away again. “Don’t make me repeat myself.” 

“I believe you.” Ryusui gave a slight smile, more genuine this time. 

Ukyo turned to leave, but after a few steps, he paused. 

“Also…” He muttered, almost to himself. “Someone has to make sure you all don’t completely butcher the harmonies.” 

“So… is it okay if I tell everyone, besides Chrome, that you’re in?” Ryusui's eyes lit up. He teased him a little. 

“Do whatever you want. Just don’t forget what I said.” Ukyo didn’t look back. 

“I wouldn't dream of it.” Ryusui chuckled under his breath. 

Ukyo walked away without looking back, but Ryusui watched him for a moment longer — thoughtful, maybe even a little nervous. Because this time, in case he messed up, Ukyo would really walk away and never return.

Later that evening. Chrome is seated at his desk, surrounded by scraps of science equipment and open notes about the charity event’s setup. It’s been two days since Ryusui had told him he would convince Ukyo. Since then, Chrome has been very stressed about it. He stares at his phone more often waiting for the text. He even had been brainstorming ideas to convince Ukyo since then.  

Click. Click. 

Suddenly, his phone vibrates. He quickly grabbed it. A text from Ryusui. 

Ryusui: Operation convinced Ukyo was a success. 

“Wait… What?!” Chrome’s eyes widened.  Another text follows.

Ryusui: He's in. You own me dinner. 

Chrome drops back in his chair, letting out a huge sigh of relief. Dinner was the least important thing right now. He really gets excited now that Stone Age is complete. 

He immediately starts typing. 

Chrome: Really!?!

Chrome: I thought I was gonna have to give him a whole science-saves-the-oceans speech  

Chrome: THANK YOU!!!

Ryusui replied by sending a smug emoji and a thumbs-up. Chrome laughs to himself, looking at the list of ‘possible persuasion tactics’ he had jotted down. He crosses them all out in one stroke. Then he grabs his phone again, ready to update Francois. 

Chrome: Ukyo’s in. We’ve got the whole band.

Chrome: So, when can we meet with you? We want to talk about plans. The real ones.

Chrome: Also, I know we never said it out loud, but to me, and probably the others too, you’ve always been our only real manager. Really. 

Chrome let his thoughts take control. 

“We’re really doing this…” Chrome said to himself. His eyes drift to a framed photo near his desk. A photo of Stone Age in their early days, sweaty, and laughing after their first public performance. 

— 

Elsewhere Francois read Chrome’s message again, then began typing, elegant, and precise as ever. 

Francois: Understood. My schedule is cleared for this weekend. 

Francois: Tell them to the cafe Stone Age used to come often Sunday morning. Before opening. I’ll make sure to reserve a private room only for us.

Francois: And Chrome-sama, I believe this is possible. It’s good to know some things and some people still have their spark. 

Francois sets the phone down, already pulling out a leather-bound notebook. The old Stone Age folder — neatly labeled with each member’s name — is placed on the table. 

— 

As told, Chrome quickly made a new group chat and sent what Francois had told him. Everyone read it. 

A mixed reaction came. Some are excited about it. Others are unsure how to act when they see their ex-partner after so long. Others don't want to make the same mistakes they made before. Others expect to have better communication between them. And others hoped for a wonderful reunion. 

But for now they would have to wait until Sunday. The day they would reunite as a band. 

—

The date of the reunion came faster than expected.

Soft golden light filters in through the café windows. The chairs are still flipped on the tables. The smell of freshly ground coffee fills the quiet space. A small ‘Closed’ sign hung at the door, shutting the world out.  

Ryusui, with Francois at his side, was the first to arrive. As promised, they had reserved a private room upstairs, discreet but warm just enough comfort to keep the meeting from feeling too sharp. Francois, as precise as ever, had already ordered everyone’s drinks. They remembered everyone’s usual. 

It didn't take longer until another person arrived. Senku was next, white hair with dark green tips catching the light as he entered. Francois greeted him politely before excusing themselves to fetch the drinks. Ryusui immediately engaged Senku in conversation, the tone polite but not personal. After all, they were the ones who initiated the fight that led Stone Age to separate. They talked about scientific achievements, world headlines, nothing that touched the fault lines beneath.  

At the entrance of the cafe, Chrome walked in, wide-eyed and slightly out of breath. He quickly spotted Francois, ever impeccable, as they arranged mugs and a small tray of pastries. 

“Yo! Francois!” He beamed as he approached the butler. “I’m not too early, am I?” 

“Not at all, Chome-sama. Ryusui-sama and Senku-sama are already here.” They responded with their usual politeness. Chrome eyes lit up as he noticed the mugs, each labeled neatly 

“Wait … you actually remember my old drink order?” Chrome added curiously. As he grabbed the cup labeled with his name. 

“I remembered all of you.” Francois answered simply. 

Chrome followed them upstairs, bursting into the private room with energy only he could carry. He greeted everyone cheerfully and dropped into a seat beside Ryusui, leaving the head chair for none other than for their manager. 

Minutes later, Ukyo arrived. The air shifted. Ryusui’s golden gaze met Ukyo’s calm one, and though nothing was said, the silence stretched heavy between them — not hostile, not yet, but brimming with everything unsaid. Chrome, sensing the tension, immediately began rambling about nothing in particular to keep the room afloat. 

And then, fashionably late as always, a man with black and white hair swept in. 

“Hello, my fellow friends!” Gen  sang out, smiling brightly — his typical fake smile. His mask cracked only for a heartbeat when his eyes locked with Senku’s. The pause was short, but long enough for everyone to notice. 

“Well, hello, Senku-chan.” Gen added smoothly and tried to act casual as if nothing had happened. “You’re still pretending humans are equations.” He used a little icebreaker. 

“And you’re still overcomplicating simple variables.” Senku replied dryly, not looking up from the cup in front of him. There was no outright hostility, but a wall stood firmly between them. Chrome, again, jumped in to change the subject, while Gen slipped into the seat beside Ukyo. A seat away from Senku. 

The table felt crowded with ghosts. Nostalgia and unfinished business pressed in from all sides. 

For the first time in years they are back in the same room.

“Welcome back, everyone!” Francois announced as they entered, seating themselves at the head of the table. “It’s a pleasure to have you all agree to one last performance at this year’s Marine Safety and Scientific Education Charity Gala.” 

The nods around the table were polite but right. Francois, sensing the strain, offered a deliberate icebreaker. 

“To begin properly.” They said, eyes sweeping the room. “I suggest we air any unresolved business and apologize where necessary.”

Silence.

It was Ryusui who broke it.  

“Chrome pulled us there. He should start.” He suggested.

“For once, I agree.” Ukyo said. His voice wasn’t sharp, but it carried a weight that made Ryusui glance away. 

“Well then.” Chrome cleared his throat nervously, then spoke with more earnestness than usual. “Look, I know there’s stuff we never said. Stuff we never fixed. But I’d rather try than regret never trying. Back then… we lacked communication.”

“This time, even if it’s just for one height, I want us to be more open.” He continued. “I cared about Stone Age. About all of you. The way we ended. No goodbyes, no closure. Just silence.  I hated it.”  

His honesty landed heavy. 

“I’ll go next.” Ryusui’s voice, unusually serious, cut the quiet. “ I apologize for always chasing the spotlight… and leaving you all behind. I’ll try not to this time.”

“You didn’t just chase it, Ryusui.” Gen interrupted smoothly. His eyes, sharp now, flicked toward Ukyo. “You drowned in it. You stopped listening. To us. To him.” 

The table stilled. Ryusui’s smirk faltered. 

“Back then, I thought I was doing what was best for Stone Age.” He muttered. 

“No.” Ukyo said flatly. “You were doing what was best for you.” His calm tone made the words cut deeper. 

“I know. I can’t fit it overnight. But if I could change how things ended…. I would.” Ryusui looked down, guilt flickering in his eyes. 

Ukyo hesitated, choosing his words with care. Finally, he admitted quietly.

“I never stop listening to our songs.” The confession dropped like a pulse through the room. “You all probably thought I hated it. But I couldn’t let go. I just didn’t know how to come back.” 

Ryusui’s eyes softened, guilt carving deeper.  

“Maybe none of us did.” Senku muttered suddenly. He leaned forward, voice brisk but edged with regret. “Back then, I acted like a brat. Last minute changes, bad leadership. I’ll own that.” 

He wanted to say something more but preferred to stay quiet. He would say it later. 

Gen adjusted his cape, tone lighter but his eyes betraying nerves. “ I suppose I should apologize too. For dragging us into scandals. I was immature.” He paused. “And reckless.” 

“Especially for one in particular.” He didn’t say it aloud. 

“It was my fault too.” Ryusui added quickly. “Most scandals started with me.” 

The silence that followed felt different now. Not the silence walls, but of doors creaking open. A possibility. A spark. 

“Good. Now that we’re all still here, shall we begin?” Francois nodded.

They look at each other. Old scars are still visible. But old bonds too. 

“We’re actually doing this.” Chrome smiled wide. For the first time. 

“Let’s just try not to kill each other before the first rehearsal.” Gen let out a theatrical sigh. 

“Just don’t make another impossible choreography.” Ukyo added dryly. 

“No promises.” Ryusui smirked. 

And then — they laughed. It wasn’t much, but it was real. The kind of laughter that only happens when something broken starts to mend. 

— 

The mood had softened. Cups sat half-empty now , conversation easier now, more relaxed. Though the air still hummed with vulnerability.

“So, we already discussed all the important details of the performance at the Gala.” Francois cleared their throat gently. “I’ve scheduled a meeting with the organizers to confirm your slot and the time we’ll have.” 

As always, Francois was one step ahead — preparing every detail flawlessly. Everyone followed and understood each point they laid out.  

“So, we’re only missing one thing.” Francois began their final statement. “Your crew.” 

“I think we all want the original crew.” Senku said immediately, confident everyone would agree. His tone was sharp with certainty. 

“I agree. No replacements. No fill-ins.” Gen added firmly, making it clear he supported Senku’s stance. 

”Every single person who was with us before.” Chrome jumped in with excitement. “Techs, audio engineers, lighting, support, everyone!” He made it sound so simple. His optimism made it sound almost naive. 

“That won’t be so simple.” Francois replied thoughtfully. “Some of them have moved on to others jobs, others cities, —”

“If they hear Stone Age is back, they’ll come.” Ryusui declared with confidence, his snap of the fingers like a promise. 

“We’ll call them. Each of them.” Ukyo said, voice sharp and resolute. 

“And if not, we’ll convince them. Emotionally. Strategically.” The mentalist’s smirk was subtle but dangerous, his words carrying that teasing edge that masked determination.

Francois studies them all carefully. For the first time in years, they saw it — the determination, the same fire was back in their eyes, the spark returning. 

“Very well.” They pulled out a tablet, opening a digital folder of the original crew. “I’ll assist in contacting them. But you will do the convincing. One by one.” Their tone left no room for doubt. 

The band exchanged glances. For the first time in years, they all feel aligned. They were on the same page… at least for now. 

“Some of them will be easy to contact… others, less so”  Francois continued, scrolling through the files. “But I believe you still have connections.” 

“Leave Taiju, Yuzuriha and Suika to me.” Senku’s voice was confident, almost defiant. “I’m still close friends with them.” 

“How wonderful, Senku-chan.” Gen teased, a playful smile tugging at his lips. Though his eyes gleamed sharp. “Tsukasa’s mine. He’s my bodyguard, after all. I’ll get him with a little mentalist persuasion.”  He  grinned mischievously. 

“I’ll get Kohaku and Kaseki.” Chrome announced, making no effort to hide his excitement. “I’ll be visiting them with Ruri this week.”

Almost in a whisper, Chrome didn’t  catch that Gen and Ukyo were quietly gossiping, wondering if he had finally confessed to Ruri, his long-time crush. They quickly stopped when Chrome caught them with a suspicious grin. They would resume their gossiping session another time. 

“Nikki’s on me.” Ukyo said without hesitation. Everyone blinked at him, surprised. They’d always assumed Nikki would be the last person he’d talk to. “What? We’re good friends.” 

“Ha ha! Minami’s on me!” Ryusui proclaimed, as confident as ever. Not everyone was convinced, considering his constant scandals and how Minami always had to clean up after him. Their relationship was… complicated. But no one dared to comment.  

Chrome, however, trusted Ryusui enough to believe he could handle convincing Japan’s top reporter. After all, Ryusui managed to convince Ukyo. 

“Excellent.” Francois began packing up. “That leaves Hyoga, Kinro, Ginro, Homura, and a few others. I’ll track their locations and recent activity. You’ll handle the convincing.” 

“Since we’re nearly done…” Chrome stood a little nervous, raising his empty cup. “How about we end this like we used to?”

He didn’t have to wait long. One by one, the others raised their cups. First Ryusui, then Senku, Gen, Ukyo, and finally Francois. 

“Stone Age!” They shouted in unison. The world struck the air like an echo of the past. It felt nostalgic, powerful, and almost fragile. 

“Before we conclude.” Francois said after a pause. “Should I announce the reunion on Stone Age’s official account?” 

“We haven’t posted anything in… what, five years?” Gen muttered bitterly,  unsure if it was a good idea. 

“I think we should.” All eyes turned to Ukyo, surprised he was siding with the media for once. “Let’s see if our fans are still out there.”  

“I love it!” Ryusui agreed while he snapped his fingers with his usual flair. 

“Oh, make it mysterious! Like we’ve got a big announcement but without revealing the reunion just yet!” Chrome jumped in, hands gesturing wildly. “Like a hidden announcement, just a tease! Picture it, my vision?” 

“Only Japan’s greatest producer could come with that.” Senku said dryly, though the hand on Chrome’s shoulder was genuine. 

“Chrome-chan really has  made a name for himself!” Gen teased with an almost soft smile. A genuine one. 

“Very well then.” Francois inclined their head. “I’ll upload it as soon as possible.” 

And with that, the meeting officially ended. 

At least they hadn’t killed each other during their first reunion. 

But beneath the laughter and nostalgia, the air still carried cracks. 

Sooner or later, some would have to confront old wounds and unresolved issues.   

Others would need to apologize or even do more than just a simple apology.

And others… would have to make sure everything stayed together before it all fractured again.
