Chapter Text

"I hate it, but it's almost time for you to go Kats. Third years still have curfew checks, you know this." Katsumi groaned as she snuggled deeper into her boyfriend's embrace.

Katsumi whined, "I don't want to go."

She heard her boyfriend laugh and his laugh rumbled through his chest. "I know Kitty Kat, but unless we want a lot of questions, you gotta."

She rolled just enough to glare at her boyfriend. He was right, but that didn't mean she had to be happy about it. "We're eighteen. We shouldn't have a damn curfew." She had been glaring at him, but she kind of got distracted. Her boyfriend was pretty. He had the brightest blue eyes she had ever seen. He was lean and had light blonde hair that he had let grow shaggy in their third year.

She was dating the one and only Neito Monoma. Class 3B's residential shithead, Class 3A's bane of existence, and the boy she was currently in love with and had been for the last year and a half.

What started out to be a mutual hatred and rivalry in their first year turned out to be mutual attraction in their second. They clicked and they just worked together. He was a snarky shithead and she was a sassy asshole. They just worked.

Class 3B knew of their relationship, and the only ones of Class 3A that knew of their relationship was her best friend Kyouka Jirou and Neito's best friend Shinso. They just hadn't told the rest yet, well because her class really didn't like her boyfriend and she just didn't want people in her business. Neito had harassed her class for the last three years, and as nice as some of them were, they held grudges.

There was something else that she was hiding too, and that's that she's trans. Nobody except her parents, her boyfriend, Kendou, and Kyouka knew she was a girl.

Neito had taken the news well when she had told him before they started dating. She wanted him to know the real her. He happily accepted her and loved her for who she was. He had told her exactly, "Boy, girl, anything in between. I like you for you. I want to be with you for you."

The only reason Kendou knew was because she had accidentally walked in on Katsumi straddling Neito while she was in just her bra and panties. That had been an awkward conversation and she still hated thinking about it.

She knew most of her class and Class 3B wouldn't care that she was trans. She just didn't know how to go about telling them. Besides, it was her business. She wanted to be out, she did. She wanted to be herself, but, she was just scared. She was scared. Yaoyorozu had come out as a trans girl in their second year, and she was accepted, but she wasn't Yaoyorozu. She wasn't as nice and sweet and pretty. Yaoyorozu had been on hormones for years and everyone already knew her as her. Nobody knew of Katsumi yet. She was just Bakugou. She was the demon spawn of her class. Yeah, she luckily had some feminine features and she had mellowed out for the most part, but she was still herself. She was crude and still somewhat aggressive. She was scared no one would see her for her.

She groaned as she sat up. She pulled her hair up into a ponytail. She had been growing it out for the last two years. She stood up to grab her shirt and sweats. As she bent over to pick up her clothes, she heard Neito move and then she felt a smack on her panty clad ass. She clutched her clothes in one hand and put her other one on her hip as she turned to look at him. "Doing shit like that is not how you get me to leave. That's how we get in trouble."

He just a grinned a shit eating grin at her as he propped himself up on one of his elbows. "I can't help it, you're the one who bent over in front of me."

She rolled her eyes as she slid on her normal skull shirt over her pink tank top. "Yes, cause me bending over means you just have to smack my ass." She rolled her eyes again as she pulled on her sweats.

He chuckled. "My hands are tied. Rules are rules. I see you bent over, I spank you."

She finally broke and grinned at him. "Shithead."

He rolled out of bed and made his way over to her. "Asshole."

She ran a hand down his bare chest, "Yeah, but I'm yours."

He smirked and brought her into a kiss. "That you are, just like I'm yours."

She smiled into the kiss. Then he peppered her jaw with light kisses. She tilted her head to give him better access. "Neito, you keep that up, I'm not leaving." He continued to nibble on her jaw and down her neck. She flexed her hand and clenched it. "Mmm, N..Neito, honey, please."

He nuzzled into her neck and chuckled, "You know I have no problem with you staying here, but you just know people are going to ask questions. You not coming back on a school night? Your friends will freak out."

She sighed as his teasing came to an end, "Put on a shirt and walk me to the door, fucker."

He kissed her again, "Anything for my girl."

They walked down the halls and down to the common room. There were still some of 3B milling about, she waved at them as they walked by. The two of them stopped by the front door to the 3B dorms.

Neito pulled her into a kiss. It was a gentle goodnight kiss. "Message me when you get there."

She smiled and playfully rolled her eyes. "Neito, it's a three minute walk and I literally explode things with my hands." They both knew she still would message him.

He gently gripped her chin, "Still. Do it for me, please."

She nodded, "You know I will."

He kissed her one more time. "Good." He whispered to her. "I love you, my Katsumi."

She melted into him, "I love you too, Neito."

She had forgotten her coat up in his room. She watched as he grabbed one of his hoodies from a hook on the wall. It was a navy blue hoodie that he wore constantly. It was the one she stole most of the time anyway. She smiled as he slipped it on her. It smelled like him and that brought her comfort.

Katsumi waved to him and walked back towards Heights Alliance. It was a cold November night and it had started to snow. She messaged Neito as she walked up the steps of her dorm building. She walked inside and was instantly met with Iida's stern voice. "Bakugou. There's only thirty minutes left until curfew. You're really starting to cut it close."

She rolled her eyes. She was not in the mood for his shit. "You're not my damn dad. I was busy."

He softly grumbled from behind her, puzzlement clear in his voice. "When did you turn into a teenage girl?" Katsuki couldn't help but smirk to herself as she pretended not to hear him.

She walked through the common room. She nodded at Kyouka who knew where she was. Some of her other close friends were down in the common room too, like Eijirou and Mina. Eijirou looked at her, "Were you training? It's pretty late to be training bro. You got to take a break."

Katsumi shook her head as she walked through the common room. "I was just busy. Kyo knows where I go. I'm safe and that's all that matters. Everyone can stay out of my business."

Everyone turned to look at Kyouka. She just shrugged, "Kats is safe. Nobody needs to worry."

Uraraka popped up beside Iida. "We're just curious where you go Bakugou. You disappear at random times. Sometimes you're gone for the entire day after class."

Katsumi sighed. These fuckers weren't going to give up. "I have a boyfriend. That's all you fuckers are getting out of me."

An ear piercing squeal split the air. She turned to glare at Mina. "Pinky, what the hell?"

Mina just grinned, "You have a boyfriend? That's totes adorable! Who is it?"

Katsumi shook her head. "Nope. You're not getting anymore out of me."

Mina whined. "Bakuuu." She then turned towards Kyouka. "Jirou, do you know?"

Her best friend rolled her eyes, "Of course I know, and no I'm not telling you."

Before Mina could keep whining, Shinso walked into the room. "What's with all the squealing going on in here?"

Mina huffed. "Blasty has a boyfriend and he or Kyo won't tell us who it is."

Shinso just shrugged, "I know who it is too."

Mina looked stunned. She looked from Shinso back to her. "I can understand that Kyouka knows. You two are inseparable, but Shinso? You two barely talk. Why does he know and we don't?"

Katsumi dropped her head back and groaned. "The fucker just knows. It's not important. I just have a boyfriend. It's not national fucking news."

Eijirou gently smiled at her. "As long as he treats you right. That's all that matters."

She couldn't help but smile at the thought of Neito. Nobody treated her as well as he did. He treated her like a princess, and not in a condescending way either. "He treats me just fine."

She was getting done with this. She just wanted to call Neito before she went to bed. "This hasn't been fun. I'm going to bed." She nodded towards Kyo and just made her way out of the room. She liked being able to fall asleep to the sound of her boyfriend's voice.

Katsumi was sitting in homeroom the next morning. She was chatting with Kyouka when she heard a very familiar voice enter her class. "Hello, my darling class of losers."

Neito entered the room giggling. Almost the entire room groaned. Katsumi tried her best to repress a snort. Kyouka smirked at her and rolled her eyes. She whispered to her, "Your boyfriend is such a dick."

Katsumi was trying to hold in her giggles. "Yeah, I know."

Katsumi noticed Shinso wave at Neito from the back of the class and Denki pouted. Shinso and Denki were a couple but Denki still couldn't stand Neito being his boyfriend's best friend. It made her want to laugh. Denki rolled his eyes. "What are you doing here Monoma?"

Neito locked eyes with her for just a split second before a massive grin broke its way to his face. "I just had to stop by to see my favorite class and come see my favorite princess."

He smirked over at her and she had to work very hard at not smirking back. He called her princess because it was a way for him to affirm her identity, but he also got to seem like he was just being an asshole because nobody else but a very select few knew. He could call her miss and say she and her and nobody batted an eye because they all just thought he was being a dick. It was a fun little game they got to play.

The class groaned. Eijirou looked over at her. "Don't mind him, bro."

Mina huffed, "I'd rather Blasty beat the smirk off of his stupid face."

Neito tutted, "Now that's not very nice Class A. I was just coming to see how my favorite blonde was doing. Don't speak for her."

On the inside, Katsumi wanted to giggle, but she had a part to play. She snarled, "What do you want? Fucker."

She could see the absolute amusement dancing behind her boyfriend's blue eyes. "I want another shot at a sparring match. You may have won the last one, but you won't win this time."

A smirk made its way to her lips. Their "sparring" sessions usually consisted mainly of half assed play wrestling and making out when they had the gym to themselves. She clicked her tongue. "You're on shithead. I've beaten you every single time. This time will be no different."

A spark ignited behind his eyes. Neito grinned, "I believe I really won last time."

She wanted to bite her lip when she thought of what had transpired last time. What had started as play wrestling quickly escalated. It escalated to them running back his dorm and him making love to her for the first time. She stared back at him, "I definitely won."

He laughed. It wasn't his over the top laugh that he did to laugh at her class. It was his actual laugh. It was low and she loved laying her head on his chest so she could hear it rumble through him. "I guess our rematch will be the decision then."

Gods she wanted to do nothing more than walk over and kiss his stupid and pretty face.

The bell signaling class started in five minutes chimed overhead. Neito grinned, "I'll see you losers later. Especially you, princess."

With that he left and Katsumi had to work hard at hiding her smile. She absolutely loved that shithead.

After school was over, her and Kyouka made their way to the gym. Kyouka smirked at her, "Try not to get caught humping your boyfriend in the gym during your "sparring" session."

Katsumi felt her face heat up. "Shut up. We're just going to spar."

Kyouka rolled her eyes, "Sure you are."

The two of them walked to the gym where they found Neito standing there waiting. He smiled at them. Katsumi seen him check around before leaning in to capture her lips in a quick kiss. She happily hummed and smiled into the kiss. She would prefer the kiss to last longer, but they were in the hallway.

Kyouka just snorted. "I'll see you two later. I have a study date with Mo. Don't be too gross."

Katsumi put her hand on her hips, "You have no room to talk. If I remember correctly, you and Ponytail were almost caught fucking in the library just last week."

Her friend's face turned pink. "Shut the fuck up. I shouldn't have told you that."

Katsumi grinned from ear to ear. "I'm your best friend. We tell each other everything. Those are the rules."

The shorter girl rolled her eyes, her cheeks still pink. "Whatever. I'll talk to you later baby girl."

Katsumi waved. "Later babe."

Katsumi turned towards Neito who was grinning at her. "If I didn't know better, I'd be jealous. Baby girl? Babe? Sounds like things are serious between you two."

She snorted as the two of them walked in the gym hand in hand. "Yeah, because we both know Ponytail would be so happy sharing her with me. That girl is so protective of that short stack." She looked up at Neito. "Besides, you know you're the only sarcastic asshole for me."

Neito grinned, "Love you too, princess."

They began warming up, and as she stretching, she felt Neito come up behind her. He placed a hand on her hip, she thought he was going to be sweet, but he ended up just snapping the waistband of her panties against her skin.

She turned to face him and lightly shoved him back. "Fucking jerk."

He grinned as he slowly approached her. "I couldn't help it. Pink is just your color. So cute." That's when he went to tackle her and take her down.

She let a high pitched squeal of laughter out as he took her down. She let him pin her at the wrists as he straddled her waist. He grinned down at her. "Give up Kitty Kat."

She pretended to struggle. "Never."

He leaned down, keeping his lips just out of reach. The damn bastard. "Give. Up. Katsumi." With each word he would get close to kissing her but then he would pull back.

He held his lips just out of reach, even when she would raise her head to chase him.

They had the gym reserved for next thirty minutes so the last thing she was expecting was a slam of a door and a familiar voice calling out. "Katsuki!?"

Chapter Text

"Katsuki!?" Katsumi froze at the sound of a familiar voice. She knew that voice very well. Her and Neito looked over at the gym doors to see Eijirou, Mina, Hanta, and Denki staring at them with slack jaws and wide eyes.

Katsumi watched as Eijirou rubbed his eyes as if to wipe away what was happening in front of him.

Katsumi looked back over and up at her boyfriend who was still straddling her waist. They were way too close to play it of as anything other than what it was. She could see his blue eyes looking down at her. He whispered to her, "How do you want to play this Katsumi?"

She looked him directly in the eyes. She wasn't going to hide him. She may not want people in her business, but she wasn't going to go out of her way to hide him. "I'm not ashamed of you. I may not want a bunch of fuckers in our business, but I am not ashamed of you. If they want a show, we'll give them a show. Kiss me."

She could see his blue eyes sparkle with love and amusement. He leaned down and held his lips right out of reach. "Yes ma'am." He then kissed her right in front of her friends. Her hands came up around him as she draped them around his neck and kissed him back.

Katsumi wondered if they kissed long enough that their audience would leave, but she knew her friends. She knew they weren't going to leave without an explanation. Her and Neito broke their kiss. He winked at her. "Let's go talk to your loser friends, princess."

She rolled her eyes at him as he got off of her. He extended a hand to her which she took and he helped pull her up.

She looked over at her slack jawed friends. "The fuck you assholes staring at? Besides, why are you here? We had the gym reserved for our half an hour."

Denki scratched his head, "We wanted to see you beat Monoma into the ground. Apparently that's not what goes on during your sparring sessions." She did not appreciate the edge to his voice.

Neito apparently didn't either because she felt his arm wrap around her waist and pull her close. Katsumi glared at her friends. "Do you have a problem with my boyfriend?"

Eijirou grunted, "Bakubro, how can you date this guy? He's an asshole. You deserve someone better."

She growled, "Neito treats me perfectly fine. He treats me more than fine. We've been dating for over a year. I love him, so watch what you say."

Mina apparently decided to take a gentler approach. "You love him? He loves you?"

Katsumi felt her face soften as she looked at Neito, "I love him."

Neito smiled at her. "I love you too."

She heard Mina audibly coo. She could always count on her pink friend on being a sap for romantics.

Neito turned towards her friends. "Whether you idiots like it or not, princess here is my partner."

Eijirou rolled his eyes and then looked at her, "How can you be with someone who constantly calls you names and makes fun of you? You deserve better than this jackass."

Katsumi crossed her arms. "What has he called me in that last year that consists of him making fun of me?"

Hanta started listing off things, "He calls you princess, girlie, pretty lady, his damsel. He calls you these things to be demeaning, doesn't he?" He paused for a moment. "..unless you enjoy that he calls you those things."

Katsumi couldn't believe what she was about to do. As annoying as they could be, other than Kyo, they were her closest friends. She needed them to understand why Neito called her those things. He was doing it to affirm her identity. She sighed, "Is there any other reason why he would call me those things?"

Neito's embrace on her hip tightened. "Kitty Kat, are you sure?"

She looked at him and nodded. "I'm sure."

Denki was massaging his temples, "What do you mean any other reason? What reason would there be?"

Katsumi heard a growl start low in Neito's throat. "Just fucking listen to what Kats has to say. I swear if I hear one ounce of disrespect. I'll wipe the floor with you 3A losers with your own quirks."

Eijirou looked at her, "Katsuki, what is going on?"

She took a deep breath in and out. "Neito calls me those things because I'm a girl. I'm trans." She sighed. "My name is Katsumi." Her chest filled with euphoria with getting to say it out loud. She would never get over that feeling of being able to admit out loud that she was a woman.

Neito glared at them. "Katsumi is my girlfriend. My girlfriend I happen to adore. You will respect her."

Eijirou snarled. "Of course we're going to respect her, you asshole. We're her friends." His eyes softened as he looked at her. "You do know that we support you, right Katsumi?"

She nodded, "I knew you guys would. I was just nervous. I was scared I wouldn't be seen as a real woman, not primarily by you guys, but just in general."

Mina smiled at her, "You're just as real as I am."

Katsumi sighed. "Not everyone is going to see it that way."

Mina huffed, "Well those people don't matter then. Anyone who has a problem with you doesn't matter." The others nodded and agreed.

Eijirou sighed, "I cannot stand your boyfriend, but Katsumi, I will always support you."

Denki nodded, "We'll always support you, but could you maybe date like anyone else? Like anyone else? Maybe Kyo? You two are super close, maybe you can date her."

Katsumi huffed. "One, Kyouka and I already tried dating in our first year. We're just better as best friends. Two, you know she's with Yaoyorozu. Three, keep insulting my boyfriend and I'm going to plug you into a toaster."

Mina cooed again, "Maybe we need to give Monoma a shot. I mean, look at how he looks at her. You can see how much he loves her. It's so cuteee."

Eijirou looked over at the Mina, "This is Monoma we're talking about. He's an asshole. He's not capable of nice emotions."

Katsumi was starting to get upset. She's glad her friends supported her, but she was tired of them talking bad about her boyfriend. They didn't know Neito like she did. Yes, he could be a shit, but he was also kind and loving and sweet. She was just about to tell them to fuck off, but Neito beat her to it. "As much as I love hearing how much I get under your thin skin, our time in the gym is about up. Don't go blabbing about anything you heard today. Class B, Jirou, and Hitoshi know that Katsumi and I are dating, but only Jirou and Kendou know she's trans. So watch your mouths. You out her and I'll kill each and every one of you."

He nosed into her hair and whispered into her ear, "Let's go back to my room. I can continue kicking your ass there."

She playfully rolled her eyes, "You're on shithead."

She looked at her friends, "Seriously, don't tell anyone. I'm not hiding Neito, we just don't want people in our business. Our class can hold grudges. I'll tell people if I want to. Definitely don't tell anyone about me. I'll come out when I'm ready."

She could see Neito flash a smile out of the corner of her eyes. "The princess and I are heading back to my dorm. We have a sparring session to continue, since we were interrupted."

She smacked at his arms and he giggled like a crazy person. She fake glared at him. "Do not be an instigator."

Eijirou looked physically pained, "Please tell me you're not going to do what I think you're going to do."

Katsumi put her hands on her hips. "I'm eighteen and you're not my mom. I can mess around with my boyfriend."

She grabbed Neito's hand, "Come on, let's get out of here."

She heard Neito giggling once again, "Bye 3A losers."

They got back to Neito's dorm and shut the door. She threw her gym bag down. "I mean that could have gone worse. I'm glad they support me, but judging you is going to get old real quick."

Neito came up behind her and wrapped his arms around her tummy. She leaned back into him, as he kissed her temple. "I don't give a shit what those idiots say about me. Plus if we're being honest, I probably deserve it at least a little."

She sighed, "I care though. I love you and I know how sweet you are. They don't know everything about you, the nightmares you had about me. They don't know what you had to see that day, hardly anyone knows that."

He kissed under her ear, "I care about making you happy. You know your class doesn't like me. Part of that is my fault, but my concern is you. Keeping you happy. They don't need to know anything else."

She grinned as she pressed her rear slightly into his crotch. "You do make me happy." She purposely whined slightly as she felt his cock press into her ass. "You make me feel other things too."

She could almost feel him smirk as his hand traveled to her waist and into her shorts. He snapped the waistband of her panties against her skin and she whined softly. "Neito.."

His hand traveled up under her shirt and bra next and tweaked one of her tender nipples. She was almost at her six month mark from starting HRT. Her small and tender breasts were almost to the stage they would really start developing. She wouldn't be able to hide them much longer. There was a reason she changed alone when putting on her hero costume.

Katsumi couldn't help but grind down against her boyfriend as he played with her breast. He used his other hand to grab her ponytail and pull her head back. She felt him nuzzle into her neck. "You're so beautiful. My beautiful Katsumi."

She bit her hand to keep from crying out as she felt him sink his teeth into the space between her neck and shoulder. He rolled his hips and thrusted into her. She could really feel his hard cock pressing into her ass through her shorts. She took her hand out of her mouth, "N..Neito..Please."

She couldn't help it this time as she cried out when she felt his tongue trail over the sore spot he had just bit. He nosed up her jaw. "Does my princess want me to fuck her pretty pussy?"

She gasped slightly. She loved when he called her hole her pussy. He brought two fingers and tucked them into her mouth. She sucked on the appendages. She held them between her tongue and the roof of her mouth. She made sure to fully coat his fingers in her saliva.

He withdrew his fingers and she felt him nudge her feet apart more and he bent her over slightly. "That's such a good girl. You ready babygirl?"

She mewled, "Yes daddy." She heard him growl slightly behind her. She knew what calling him daddy did to him.

Right when he was slipping his hand into the waistband of her panties down to her pussy, there was a loud knocking on the door.

She heard Neito curse under his breath as he pulled his hand out of her panties. "Fucking hell." She could hear him clear his throat, "Who's there?"

Kendou's voice came from the other side of the door. "I'm sorry if I'm interrupting anything. Katsumi, one of your classmates is at our front door. The red head, Kirishima? He says he's looking for you."

She turned around and raised an eyebrow at her boyfriend while answering Kendou. "Thanks, Kendou. Be down in a minute."

Neito looked over at her, "What does that wannabe shark want?"

She slipped on one of her boyfriend's hoodies. "I have no idea." She knew her face was still flushed from their previous activities. Hopefully it would go away but if not she could blame it on the cold weather when she stepped outside.

The two of them walked down the stairs and to the front doors where they found Eijirou waiting for them. They stepped out to meet him. She raised an eyebrow, "Dude, what's so important?"

He wouldn't look her in the eyes. "I, uh. I needed to talk to you."

She sighed, "About what?"

He scratched the back of his neck. "I..shit. Umm, did I interrupt something?"

She was starting to get agitated. "Honestly, yes you did. We're in our third year, Neito and I don't get a lot of time together so we spend the time we can together, and yes that means we do things that couples do. What do you want, Eijirou?"

He sighed, "I just..he's..."

Katsumi interrupted him. "If you are about to talk shit about my boyfriend, I do not want to hear it. I get it, you don't like him, well, I love him. He's my boyfriend and I love him. You're supposed to be my friend. One of my closest friends. You don't have to like him, but at least have enough respect for me to not talk bad about him to my face."

There was a pause between Eijirou sighed and ran his hands over his face. "You're right. You're right. I may not respect him, but I respect you. I'm sorry." She watched him step forward towards Neito. He poked a finger into Neito's chest. "Don't hurt her."

Neito scoffed and swatted at his finger. "We've been dating for almost a year and a half. You're not her authority figure. Don't act like it now because you know about us."

There was tense stare down between the two before Eijirou backed away. "I'll be watching you Monoma. Break her heart and I'll break your legs."

He walked away and left her and her boyfriend standing together. Neito rolled his eyes and dusted off his shirt. "Damn heathen. Why are your friends so set that I'm going to hurt you? You are so much more important to me than some silly class rivalry."

She fell into his embrace as he opened his arms to her. "I don't know. They just don't know you like I do."

She looked up at him as she snuggled into his chest. "I love you, Neito."

He kissed the top of her head, "I love you too, Katsumi."

Chapter Text

Kyouka rolled her eyes for what felt like the hundredth time in the last hour. It was just her and the rest of the squad minus one Katsumi.

Katsumi told her everything last night, about how the four of their friends all walked in on her and Monoma's sparring match. Katsumi told her how she came clean about her dating Monoma and about her being trans. She also told her how the group, except for Mina did not like her boyfriend at all.

At the moment Kyouka was listening to Eijirou bitch about Monoma. He had been going at it for almost an hour now.

They were the only people in the common room so they referred to Katsumi as Katsumi, making sure to keep their voices down just in case someone approached them.

Eijirou gripped the game controller in his hands. "I just don't understand how she could be with him. He's vile and rude and mean."

Eijirou pouted, "Kiri, babe, let it go. She's happy, shouldn't that be all that matters? They've been together for over a year and he hasn't done anything to hurt her. Just because he doesn't like our class doesn't mean he doesn't love her."

Denki scratched the back of his neck, "I don't know. Ei may be right, what if Monoma has some ulterior motive. He could easily break Katsumi's heart."

Kyouka rolled her eyes again. "Idiots." They all turned to look at her. "Except for Mina, you're being idiots. Katsumi is happy with Monoma. He treats her like a goddess. Do you know she told him she was trans before they even started dating and he accepted her on the spot. If he truly was the asshole you think he is, do you think he would have accepted her so easily? Plus there's so much you all don't know.

She launched into the story of how the two of them got close and started dating.

- Over a year and a half earlier

Katsumi had an issue. Well she had several, but one was more relevant at the moment. She had a crush on one of the biggest assholes she knew. Neito Monoma.

She wasn't afraid to go after him, she was sure he liked her back, but there was something important she needed to do first. She had to come out to him as Katsumi.

The two of them were on friendly terms. They flirted often, well, she's pretty sure they're flirting in those moments. If she was going to go after him, she wanted to be herself. She wanted him to know the real her, not the shell of a man she pretended to be.

Sure, this may ruin her chances with him, it may even ruin the friendship they had just started building, but she had to do it. She needed him to know.

She had told him to meet her in the library, that she had something important to tell him. That's where she currently sat. She was sitting on one of the more comfortable chairs waiting for him.

Katsumi looked up from her book and she seen him walking towards her. She waved and he grinned back at her.

He flopped down in the chair next to her. "What's up princess? What's the important news you need to tell me."

She preened at the nickname princess, and he had no idea he was affirming her identity. She subtly looked around to make sure they were alone before turning towards him. "Do you know that I like it when you call me princess?"

He gave her a shit eating grin. "I figured, you don't freak out when I call you princess anymore. Weird kink?"

She rolled her eyes. "No, you idiot. Do you notice that I don't freak out when you call me other things?"

He scrunched up his nose as he concentrated. "Girlie, damsel, and pretty lady."

She could see the wheels turning in his head. His eyes went wide and she knew he had found the answer. He looked at her, "Are you trans? Are you a girl?"

Katsumi bit her lip out of nervousness, "Yeah, I'm trans. I'm a girl."

He sat back in his chair and rubbed his chin, "Huh, so when I called you a pretty lady, I was actually correct."

She felt her face heat up at the implications of his words. She looked at him, "You're taking this rather well."

He shrugged, "I'm a jackass, but I'm not a bigot. Whatever makes you happy is what makes you happy. I will respect you for the woman you are. You're valid." He then smirked at her, "I'm bi. The handsome guy I thought I was into, is actually a smoking hot girl that I'm still attracted to."

Her eyes went wide, "You're at..attracted to me?"

He snorted, "I'm so attracted to you. That doesn't change because you're a woman."

Her voice came out a little more timid than she intended. "I'm attracted to you too."

He held out his hand, and against her better judgement, she took it. He pulled her so she stood and walked over to him, he guided her to sit on his lap which made her entire face flush a deep crimson. He tilted her chin so she was looking at him. "So what are we going to do about our situation? Hmm?"

She looked deeply into his blue eyes. She had always loved his eyes. Even when they used to be at each other's throats. Her voice came out sounding a little breathless. "I have a few ideas."

He smirked at her, but it eventually melted into a smile. "Do you?" He paused for a moment, "What should I call you princess?"

Katsumi flushed even more at the use of the nickname now. "Call me Katsumi."

He stroked his thumb along her jaw. "Such a pretty name for a pretty girl."

- Currently

Kyouka wrapped up her telling of how Katsumi and Monoma got together. She could see Mina had tears in her eyes. Her pink friend was always a sucker for romantics. The pink girl cooed, "That is absolutely so sweet."

Eijirou grunted, "I still ain't buying it. He's up to something."

Hanta messed around with some tape from his elbow, "I don't know dude. It sounds like they really care for each other. Maybe we should just let this rivalry go."

Denki shook his head. "I don't think I can ever trust or like Monoma."

Sero gave him a deadpanned look. "Kami, your boyfriend is best friends with Monoma. Now we find out that Monoma is dating one of our closest friends. You need to let stuff go."

Denki shook his head again. The blonde turned towards her. "Kyouka, I know Katsumi said you two tried to date before, but are you sure you can't try again?"

Kyouka gave him a glare. She held up two fingers. "One, Momo does not like to share and I don't plan on ever leaving her. Two, Katsumi and I just aren't meant to connect in a romantic way. We're best friends. I love her in a platonic way. We tried for several months and it just didn't work. What we thought were romantic feelings were just platonic." She paused for a moment before shrugging her shoulders. "She's a great kisser though."

Mina looked over at her, "How long have you known about Katsumi being Katsumi?"

Kyouka took a sip of her drink, "Since the beginning of first year. It was no secret Katsumi and I were close from the very beginning. We just clicked and she told me a few weeks after we started school."

It was at that time they heard the front door open and Katsumi herself was walking in. She waved at them. Jirou seen her nod her way. "Sup Kyo, sup fuckers."

Mina let out a very fake sounding whine. "The favoritism is so unfair."

Katsumi snorted. "Not my problem."

Kyouka could see Eijirou focusing on Katsumi's neck. That's when she noticed the scratches. No doubt from Monoma.

Eijirou glared, "Did that bastard hurt you?"

Katsumi looked confused for a moment, but then snorted. "Are you serious?" She moved the hood from her hoodie she was wearing so more of the scratches and a bite marks were visible. "Do you really want to know how I got these Ei?"

The red head looked like he wanted to say something, but he just gripped the controller tighter and went on playing his game.

Kyouka wanted to roll her eyes. She knew it was coming from a good place, but he was being dramatic. Besides she wasn't very happy with him. He had really upset Katsumi the day before by talking bad about Monoma to her face.

She decided to pour a little salt in his wounds, just a little. "Sumi, for real? Ever since the two of you first did it, you fuck like rabbits."

She could see Eijirou glare at the TV even harder. Katsumi stuck her tongue out at her. "Shut the fuck up. You and Ponytail are the exact same way."

She snorted. Katsumi had her there. Katsumi grinned at her in "victory" and smirked. "That's what I thought. Anyway, I have news. I think I'm ready to fully come out."

Kyouka couldn't help but smile. She was surprised, but she was happy for her friend. "I thought you wanted to wait until you graduated?"

Katsumi shrugged, "I did, but the more I've been thinking about it. The more I want to enjoy these last six months of school and be myself." She gestured to her chest. "Besides, these are getting bigger and I won't be able to hide them much longer. They don't really look like pecs anymore. I talked to Neito about it and he said he'd have my back completely. He threatened to beat up anyone who messed with me."

She smiled, "I bet he did. Well babe, you know you have my full support. I will also beat the shit out of anyone who fucks with you."

Mina was grinning ear to ear. "Does that mean you're already on hormones?"

Katsumi gave a proud smile. "Yep. I have been for almost six months."

Hanta looked like he was putting two and two together. "That's why you change in the stall?"

Katsumi nodded, "That and I don't want to change around a bunch of gross boys."

Mina giggled. "Fair. Oooh, do you think you'll be able to change with us now?"

Katsumi looked hopeful. "I really hope so. I plan on telling Aizawa tomorrow. We'll see what happens."

-

Katsumi walked into school with a purpose the next morning. She knew Aizawa would be in the teachers lounge and that's where she was headed.

She knocked on the teacher lounge door. Present Mic opened the door. "Hey little listener. Do you need something?"

She just had to be a little shit. "You're husband in there?"

Yamada went red in the face and she heard a sigh from behind him. "Come in problem child."

Yamada moved so she could enter where she found her Sensei looking at her with a tired gaze. "I regret telling the class I was married."

She snorted. "You know you love us." She took a deep breath. "I came her to talk to you about something important."

He gave her a look. She understood, she didn't really ask for help that often, or come to people in general. "What do you need Bakugou?"

She let out an exhale. "I'm..trans. I'm a girl. I've been on hormones for the past six months. I would like to change my name in the records, wear the girl's uniform, and switch locker rooms. Please."

Aizawa gave her a look, until a small grin made it's way across his face. "What's your name kid?"

She smiled at him. "Katsumi. I just want to be me."

Yamada popped up beside his husband. "We're proud of you young Katsumi!"

She grinned. Aizawa took a sip from his coffee cup. "I assume you're wanting to come out fully then? If you are and you want to wear the uniform and switch locker rooms. The school will need a note from your therapist saying you're transitioning. Don't worry, we believe you. It's just a part of a outdated rule."

She nodded, it was an outdated rule but she understood. "I can have that by tomorrow."

Aizawa smiled. "Then I'll have your uniforms ready for you tomorrow. Is that when you would like me to start using your new name?"

She smiled and nodded. "Yes Sensei."

He nodded. "That's settled then. Thank you for letting us know, Katsumi."

Euphoria bloomed in her chest every time they said her name. She felt on top of the world. She felt nervous, but she was ready for tomorrow. She was ready to just be Katsumi.

Chapter Text

Katsumi sat in class waiting for Aizawa to walk in the doors. She had turned her note from her therapist into the principal this morning. Principal Nezu had said she was good to go, and her name would be changed in the records, she'd have a new uniform, and if the other girls were comfortable then she would be able to change in the girls locker room.

She was just waiting for her teacher to arrive with her new uniforms.

The bell chimed and in walked Aizawa and she could see him holding a package that she assumed was her uniforms.

He stood at his desk. He raised a questioning eyebrow at her and she nodded in return. He gave her a small smile. "Katsumi, your new uniforms."

He tossed the package at her and she caught it with a grin. "Thanks Sensei."

Kyouka squeezed her shoulder and she heard her best friend whisper in her ear. "I'm proud of you."

There was a beat of silence before Yaoyorozu raised her hand. "Sensei, did you just call Bakugou, Katsumi?"

Aizawa nodded, "That is the name she asked to be called."

Katsumi snorted, "I'm a girl you idiots. I've always been a girl. I've been on hormones for almost six months." She gestured towards her chest. "Can't really hide these much longer so it was time to come out."

She heard Mineta mutter, "I knew they had gotten bigger."

She turned to glare at him. "Touch me and you die."

Katsumi could see Uraraka raise her hand. "Does that mean Katsumi will change with us now?"

Aizawa nodded. "She will. Does that make any of you uncomfortable? If it does, you are allowed to voice your concerns. There will be no hate in this classroom but you all are allowed to use your voices is something concerns you."

Kyouka chimed in from behind her. "I have no problem with Katsumi."

Mina squealed, "I don't either! I have no problem changing beside her."

The rest in the class shared similar sentiments and it made Katsumi's chest bloom with warmth. She was happy the rest of the girls accepted her.

Aizawa cleared his throat. "Katsumi, go get changed if you want. Once you get back, we'll discuss the plan for today." She could see him brace for impact before he said what he said next. "It's an easy day. You'll be running an obstacle course against 3B."

The room exploded into cheers. She smirked at their tired teacher before grabbing her new uniform to go change.

Katsumi changed out of her old uniform and slipped on her new uniform. The right uniform. She felt absolutely complete wearing the girls uniform. It symbolized she didn't have to pretend anymore. She could just be Katsumi.

She knew not everything was going to be simple. She knew not every hero would welcome her with open arms when she went into the field. She knew not all of the general public would be on her side. All the trans heroes she knew were met with some kind of level of backlash just for being trans. She had obstacles coming her way, but she was Katsumi fucking Bakugou and she could conquer anything.

She made her way back to class. Kyouka whistled at her and Mina cooed before Aizawa shushed them, but she could see him smile even if he tried to hide it.

He went over what they would be doing today. An obstacle course had been set up and they would take turns running it while facing someone from 3B. It was a way to give them time to breathe.

She was so going to kick Neito's butt at this obstacle course.

As soon as class ended, she walked with Kyouka and Yaoyorozu like she usually did. Katsumi could feel eyes on her as she walked the halls. She could hear the whispers. She just clutched her books to her chest and smirked. These extras didn't mean anything to her.

As she walked, Yaoyorozu asked if she was coming to the next girls' night. She hadn't even thought of that. Katsumi nodded, "I'm definitely going."

As they walked, Uraraka made her way to walk next to her. "Katsumi?"

Katsumi hummed, "Yes?"

Uraraka looked her up and down. "It's like you're a different person."

She shook her head. She knew it seemed that way. She was carrying herself differently. She spoke differently and walked differently, but this is who Katsumi was. She wasn't who they thought they knew. "This is me. You've grown to know Bakugou. He was a version of myself that I let people see, but he wasn't who I really am, not all of me at least. I'm me, I'm Katsumi."

Kyouka grabbed her around the waist and smirked, "Yeah, Katsumi is really a giant soft girlie who cries at shitty romance mangas and is just a lady who likes to be called baby girl."

Katsumi playfully shoved the shorter girl away, "Shut the fuck up."

Uraraka giggled, "Baby girl?"

She shrugged, "What? It sounds fucking cute and I'm fucking cute. It works."

Kyouka snorted, "This girl loves pastels and cutesy shit like you wouldn't believe."

Yaoyorozu hummed, "I would never have pegged you for a pastel girl, Katsumi."

She shrugged again. "Pastels are adorable."

As the day progressed, she came to realize most of her classmates were taking her coming out really well. The rest of the student body, not so much. Neito messaged her that he cleared things up with 3B so they fully understood now. The one thing she didn't do was go online. She was sure word was already getting out there. She definitely wouldn't be leaving campus unless it was for work and even then she was wearing a hoodie so hopefully people wouldn't notice her.

She was interning with Hawk's agency, but she was sure that he wouldn't give a shit if she was trans. His best friend was Miruko and she was openly trans. Katsumi really didn't worry about being out of a job since she worked with Hawks.

It was finally time for hero course training which today meant the obstacle course, which that meant it was time for her to change in the girl's locker room for the first time. She was admittingly nervous.

She met Eijirou at the boy's locker room and he handed her her stuff at the door. Things had been tense between them because Eijirou still didn't like Neito, but he did give her a little smile. "I'm proud of you."

She gave him a little smile back. "Thanks."

She grabbed her things and made her way to the girls locker room to change into her gym clothes.

Katsumi felt uneasiness creep in once she stepped in to change. She didn't want to make the other girls uncomfortable, but as soon as she walked in Kyouka smiled at her and Mina aved. She was just another girl.

She went and slipped out of her uniform and she heard Uraraka giggle, "You really do love pastels."

Katsumi looked down at herself and smirked. She was wearing a pastel pink bra and panty set that Neito had gotten for her. "It's my favorite set. I told you I liked pastels, plus my boyfriend got it for me for my last birthday."

She heard Mina giggle. "Sounds like it was gift for himself too."

Katsumi giggled as well because she couldn't really argue with that.

She meshed easily into the other girl's conversations, which she had always gotten along with the girls. She just got along better with most girls than she did guys.

They made their way to ground Beta which had been turned into a massive obstacle course. Which meant a Yuuei obstacle course, so there were fifty foot drops and thirty foot inclines. There was flying debris and even different weather events happening. Definitely an obstacle course a person could only find at Yuuei. They were allowed to use their quirks during their runs on the course against their opponents.

Didn't matter to Katsumi who she faced, she was going to win them all.

They all gathered around while Aizawa and Vladking went over the rules again. Aizawa held up his hand to quiet their excited chatter. "Vlad and I have turned this into a little class warfare. We're picking the first runners and then you can choose amongst yourselves. Katsumi, you're up first."

She smirked and stepped forward as Vladking pointed to someone, "Monoma, you're up."

Katsumi couldn't help but grin. Neito grinned at her with a mischievous glint in his eye. "I'm looking forward to kicking your butt, princess."

She couldn't help but giggle, "In your dreams." She knew she should be acting like she hated him, but she just didn't want to anymore. She was tired of hiding the fact that they were together.

They lined up at the starting line. She looked over and Neito blew her a kiss. "Get ready to go down Katsumi."

They were far enough away that nobody would hear them, and she planned to use that to her advantage. She smirked at him, "Wouldn't you rather just go down on me?"

She could see his jaw open and his eyes darken. Then the whistle blew and she was taking off like a rocket. She could hear him from behind her, "That was cheap, Katsumi!"

She laughed and never looked back. It sounded like he had copied someone's quirk, because it kind of sounded like as if Mina was behind her when she skated on her acid. Katsumi blew through the course with ease and crossed the finish line first. She waited for him to finish. He skated to the finish line, he had copied Mina's quirk.

Neito grinned at her as he crossed the finish line and walked right up to her. "That was a dirty trick."

She stepped forward too, "It wasn't a trick, it was a legitimate question."

She could see his eyes were still dark as he stepped forward again yoo. "You know the answer to that question, princess."

They were face to face now and Katsumi knew they had an audience. One of his hands came up and he asked a question with his eyes, a question she answered with hers. He cradled her cheek and kissed her in front of both of their classes. It was just a quick kiss, but it got their point across.

After they separated she felt him slip an arm around her waist. She smirked up at her teacher and Vladking, "Sorry if we ruined class warfare."

Aizawa rolled his eyes and handed over a few bills to Vladking. Vladking grinned, "You two aren't subtle. For someone who's supposed to hate Monoma, you're sure over at the 3B dorms a lot, Katsumi. I knew you two wouldn't keep this facade up much longer."

Her Sensei shook his head. "I figured you two were going to keep messing with the rest of the class until graduation."

Katsumi snorted as their teachers bickered. She turned to see most of her class staring. "What fuckers?"

Tsu put her finger to her chin, "You're really dating Monoma, Kero?"

Katsumi nodded. "We've been dating for over a year and a half."

Uraraka's eyes went wide. "That long? Who all knew?"

Katsumi smirked. "Yep, that long. Kyouka and Shinso have known the entire time. My group of idiots just found out. Neito's class knows, oh, and apparently Aizawa and Vladking." Her look turned serious, "I do not want to hear anyone bad mouthing my boyfriend. You want to talk shit, fine, just don't do it to my face."

Yaoyorozu hummed, "We sure are finding out a lot about you today l, Katsumi."

She smiled. A lot had come out about her today, but she couldn't be happier. She was out and being herself and now she didn't have to hide her relationship with Neito anymore. She was a lot happier this way.

Later that day after school had let out, she stumbled into Neito's room with him in tow. He ran his hands up her sides and pulled her into a rough kiss. He had been staring at her like he wanted to eat her since her comment earlier in the day.

She moaned into his mouth as he tweaked one of her nipples through her uniform. He bit her lip as they separated, "How about we break in that new uniform?"

She smiled coyly and shook her head in a teasing manner. "You're such a pervert."

He grinned, "I'm your pervert."

Katsumi took off her uniform jacket and tossed it before turning around so she could grind her ass into her boyfriend's hard member. He growled as he rolled his hips and thrusted into her. "I've been thinking about fucking you in your pretty pussy all day long."

She whined as he pulled her hair so her back was flush with his chest. He moved her shirt and bit down on the skin between her neck and shoulder. She cried out as she felt him break the skin and then lick the now sore spot.

Her skirt was hiked up and her breath hitched. "Daddy please." She was bent over his desk and felt her panties being yanked down as they pooled around her ankles. Her breathing picked up as she felt lube drip down her crack. She whined as she felt one of his fingers slowly and gently enter her.

He pumped a few times before adding a second finger. He added more lube and pumped his fingers into her hole. He was opening her up and getting her ready for him.

He gave her hip a gentle squeeze. "You ready, my pretty lady?"

She gyrated her hips and moaned, "Yes daddy."

He pulled his fingers out, and more lube was dripped down her entrance, and then she felt herself being stretched as he entered her hole. She whined and mewled as he let her get adjusted to him being inside her again. "I love the feeling of your tight pussy wrapped around me princess. Fuck, you feel so tight."

She moaned as he began to thrust his hips and she felt him drilling into her. He grabbed her ponytail and she felt him wrap it around his hand and pull. She hissed before moaning as he hit her prostate.

He was hitting deep within her. She felt her eyes cross, "Nnngh Neito!"

He was thrusting deep and hard, "I'm going to cum, almost there."

He slammed his hips against her and hilted himself completely into her as she felt him cum deep inside her. He panted as he held onto her ponytail. He lightly spanked her, "Do you want me to touch you down there?"

She mewled, "Yes please." She appreciated that he always asked to touch her in the front, because sometimes she was just feeling dysphoric and she didn't want to acknowledge that her front genitalia existed.

He reached around while he was still hilted into her. He gripped her member, she was already dripping with pre cum. He smoothed it down her shaft and began pumping her. She mewled out his name, "Neito.."

She wouldn't last much longer and before she knew it, she was cumming. "Neito!"

She came as her body shuddered and she whined as he finally pulled out of her.

She stood on wobbly legs as her skirt fell back down around her. She looked down before turning and looking up at her boyfriend while she pouted. "I got cum on my skirt."

He lightly chuckled, "We'll get it washed. Come on, let's get a shower."

Katsumi slightly smiled as she rubbed her now tired eyes. "I'm sleepy."

Neito kissed her, "Let's get a shower and a nap."

Katsumi felt herself sleepily nod. "M'kay."

She liked being babied and pampered, what of it?

Chapter Text

Eijirou was happily on his way down the stairs for class movie night, plus some from 3B had decided to join tonight and he was excited to get to hang out with Tet.

He was about to round the corner for the last few stairs when he heard voices, which meant some people were in the kitchen. That's not what made him stop, who those voices belonged to is what made him stop.

It was Katsumi and Monoma.

He could hear Katsumi lightly giggle. “I'm so happy I can just kiss you whenever I want now.”

Eijirou rolled his eyes at Monoma’s reply. “Princess, nothing ever stopped you from kissing me whenever you wanted to anyway.”

Eijirou had finally manned up and stopped giving the guy shit, mainly because he truly didn't want to upset Katsuki anymore. Plus the guy really did seem to make Katsuki genuinely happy.

Monoma was just really fucking smug and annoying.

Eijirou was working on blocking it out though. He'd do anything for Katsumi.

He heard Katsumi happily sigh. “Yeah, but now you get to hang out over here and stay the night in my dorm. Nobody is going to give us shit now, well, Iida might but he still acts like a damn hall monitor. He means well though.”

Eijirou heard her continue. “I want them all to know you like I know you. I want them to know what you went through and how much you mean to me. Neito, you had to watch me die that day. You had to just sit there, not being able to blink, and just had to watch me die.”

He felt his heart break. Eijirou..didn't know that. He knew some things that had gone down with everyone else and he knew what happened to Katsumi that day, it's part of the reason he's so protective over her, but he didn't know Monoma had to go through that. It makes sense in hindsight, he was up there with Aizawa for a long while.

Eijirou heard Katsumi breathing in a way that meant she was trying not to cry. “W..We weren't anything back then, but there were feelings. I liked you and you liked me, even if we didn't know how the other felt. You had to watch me die and nobody ever thinks about that. If..If Jeanist and Edgeshot hadn't been able to bring me back, one of the last things you ever saw me would have been me getting my heart blown clear out of my chest. You told me how helpless you felt. You've told me about the nightmares about losing me, and I will never act like we're never together again.”

Monoma gently shushed her. “Hey..Hey, where's this coming from? Everything is okay. I'm okay, you're okay. Not for one second did I ever feel like you were hiding me and I never hid you. We enjoyed our time together because it was simply our time together, time where it was our secret. That doesn't mean we hid each other.”

He heard Katsumi sniffle. “I..It’s just one of those days. I can see it in your eyes, I know you didn't sleep well last night and I have a feeling it was nightmares about that day. I know you better than anyone Neito.”

Eijirou let himself lean against the wall. He felt like an absolute asshole. He knew he was justified in some of his feelings towards Monoma but he had really let a class rivalry cause his closest friend pain. Maybe the two of them wouldn't have felt the need to stay a secret for so long if they hadn't felt like they were going to be judged just because the class didn't like Monoma.

Monoma spoke softly to her, but Eijirou could still hear him. “You're right, it was a rough night. Whenever you're not around, sometimes the nights get bad, but that doesn't change the fact that I never ever felt like you were hiding me, do you understand me, ‘Sumi?”

Eijirou finally kicked his ass into gear. He had been listening to a private conversation when he really didn't mean to and he didn't want to eavesdrop on them anymore if he could prevent it.

He came down the final couple stairs and could see Monoma holding Katsumi softly by her face as he wiped away a couple tears.

Katsumi noticed him and he gave her a soft smile. “You okay?”

She nodded and stood up a little straighter but she didn't leave Monoma's side. Eijirou watched as he wrapped an arm around her waist and kissed her temple.

Katsumi eventually gave him a smirk, “Hormone stuff, they make me cry like a baby sometimes.”

Eijirou nodded back at her, he wasn't going to force her to explain anything that she didn't want. The three of them stood there for a moment before Eijirou made his way over and stood in front of Monoma.

He waited a moment before extending his hand out for the blonde to shake it. “You've always looked out for her.”

It wasn't a question, it was just a fact.

Monoma seemed to watch him for a moment until he gripped Eijirou’s hand and shook it. “I always will.”

Eijirou believed him. “I know that, sorry it took me so long to see it.”

Monoma released his hand and simply shrugged. “It happens.”

The smile on Katsumi's face really made Eijirou wish he had done this a month ago. Her and him were supposed to be close friends and he had been really lacking in that department, but he was going to make it up to her.

He'd make sure of it.

Eijirou promised himself and the two of them he'd support them forever going forward.

Fast forward ten years as he's standing next to a nervous Monoma as the best man in Monoma and Katsumi's wedding, he always made sure to keep that promise.

He was the one who helped Katsumi pick out her dress.

He was the one who helped Monoma find the right decorations when the original ones came in wrong.

He was the one who held Monoma up when the guy almost passed out as they watched Katsuki walk down the aisle towards them.

Eijirou made them a damn promise and he was going to make sure he kept it for the rest of their lives.
