Chapter 1: A Strange Start Part 1

Chapter Text

DISCLAIMER: All the Nasuverse characters belong to Nasu and are property of Type-Moon, with the exception of the OC's that belong to me,the author.


The smell of burning wreckage filled the air. What was once the city of Fuyuki was now a wasteland,rooting in the giant flames that consumed everything.

In the middle of this hell there was a group of four people wandering around,trying to find a way out of this place. The group was composed of two men and two women. Ritsuka Fujimaru, Olga Marie Animusphere, Mash Kyrielight and Cú Chulainn. Mash and Cu were going at the front while Ritsuka and Olga stayed at the back of the group being protected by the two servants.

"Such destruction... The world will be like this after 2016?" Ritsuka said concerned, observing the ruins around him.

"Perhaps." Olga answered with the same concern of Ritsuka. "This is why Chaldea exists. To prevent any of this from happening." The director's fists thighten up as she looks angrily frustrated at the ground. "It was my duty to inherit my father's work and avoid the extincton of humanity. Yet, all of the recruiting masters are on the verge of death back in Chaldea."

Ritsuka felt the sorrow from Olga. "Director... "

"We didn't even start our first mission properly and half of the staff is dead now!" Olga's eyes were almost in tears. "I must get out of this place and assume the leadership again quickly. Or else I'll be nothing but a shame to my family's name." Olga took a deep breath, calming down.

"Sheesh! I've only knew you lot in the past minutes but I can say that this whole deal seems very important to the white haired lady." Cu commented, taking a look back at Ritsuka and Olga.

"Well it's a mission to save the world after all Setanta-san. Director Olga was trusted to carry that task after all." Mash,the semi-servant shielder, joined the conversation. "She doesn't want to fail by any means. But you can say by the look of it that it's something that puts a lot of weight on a person's shoulder."

"Hmmm. I see." Cu smiled. "Whatever you're doing just know I'll be rooting for you somewhere. You are nice after all and it's good to have some company in this junk of a place."

"Thank you Cu." Ritsuka thanked the caster, but Olga didn't seemed to care about it. "Like that will help us." She said softly and low but loud enough for Ritsuka to hear it.

"Hey Director, at least try to stay positive! We need to be hopeful during this."

"Senpai is right Director! Being pessimist will only worsen the things. I already appreciate the Director efforts to have come this far and enduring your father's work." Mash tried to comfort Olga alongside Ritsuka.

"You two..." Olga looked at Ritsuka and Mash with eyes that could tell she needed some emotional support.

She let it out a small smile. "Fine. I guess you both are right. But I'll make sure to scold you when we arrive back for what happened back at the reunion." Olga accused Ritsuka.

"Wow! You still remember that?! I already told you I'm sorry." Ritsuka rubbed the back of his head laughing a bit.

"You guys truly are something." Cu told to Mash as they both smiled at the other two. But then Mash felt a sudden touch of fur on her shoulder. "Huh? What is it Fou?"

The little squirrle-like creature jumped from Mash's shoulder. "Fou,fou." He made the noise again,this time pointing to the path in front of the group.

"I think he's trying to tell us something." Ritsuka said stoping on his tracks as well as the rest of the group.

A noise came up and an hologram appeard right in front of the group. "Hey guys! You won't believe it but we've detected two life sources some feet ahead of you! And it doesn't look like to be from servants!" The man in the hologram, Dr Romani told to the others with some surprise in his voice.

The group got surprised as well.

"There are other people here besides us?!" Olga exclaimed confused.

"Could it be other masters?" Ritsuka wondered. He wasn't expecting such reveal.

Mash gasped at the possibility "It may be that! We must hurry! They can be in danger!"

"But wait! That wouldn't make sense. I'm sure that all the other masters are here in Chaldea frozen inside the coffins." As Romani was about to tell the others to be careful, Olga rushed forward, towards the location of the two life signs.

"Wait Director! We don't even know if they can be on our side!" Romani tried to warn her.

"It's not time to think that! If they are indeed masters it's my duty as Director to see if they are ok!" Olga continued to run.

"Wait Director! Don't go alone!" Ritsuka followed her. Mash followed soon after.

"Going right behind you!" Cú said as he was now behind the other three. "I hope this doesn't attract any servant attention."

Romani's hologram was left alone.

"Please be safe guys."


The group,now with Olga at the front, was arriving closer to the local. As they were getting near,the sound of clashes from swords could be heard as well as some voices.

"HELP!"

"SOMEONE PLEASE HELP US!"

They were voices of...children.

Olga was shocked. "Huh? It isn't masters?"

"What are children doing in this place?" Ritsuka asked as he, Mash and Cú joined Olga and looked at what appeard to be a huge crater. Some corpses of skeletons were lying down all around the huge hole as two figures were struggling against other group of skeletons.

They were two kids who didn't seem to be older than 12. A boy and a girl.

The boy was crouched behind the girl and crying. His hands on his head, eyes closed and full of tears. The boy's hair was as white as snow and a bit spiky on the left side of the hair. He was wearing a white and black jacket, yellow shirt and black pants. The kid was really in panic.

The girl was confronting the skeletons with a sword as best as she could as if she was protecting the boy that was behind her. Her hair was equally as white as the boy's that was tied into a long ponytail by a blue ribbon and her eyes were brown. She was wearing a black and yellow long sleeve shirt,red skirt and long black socks. She was having trouble fighting off the skeletons as her right shoulder had been hit.

"Please calm down! I'll make sure will be safe!" The girl yelled at the boy to stop crying.

"We must help them now!" Ritsuka screamed to the rest of the group and started to run down to the center of the crater. He wouldn't dare to stand by and watch these kids suffer any longer.

"Wait Senpai! It's dangerous to a non mage like you! Me and Setanta-san will be the ones to take care of the enemy!" Mash went after Ritsuka.

"That idiot has a good heart but will get himself killed!" Olga critizised Ritsuka's bold atitude.

"I guess that's simply in his nature hehe." Cú laughed at Ritsuka's courage.

"Even though I can't support seeing two kids like those in danger either. Let's go help them!" And with that, both Olga and Cú went to help Ritsuka and Mash fight the skeletons.

The girl blocked two hits of the skeleton with her sword but unfortunately her legs were getting tired and she fell to her knees. As the skeleton raised it's blade to the girl, she instinctively put her body above the boy, protecting him from the slash that was about to come.

"AAAAAAAAAHHHH!" Ritsuka charged at the skeleton with all the strenght a normal human being like him could get and moved him out of the way roughly.

Both the girl and the boy, looked with a mixture of confusion and shock at Ritsuka who in return smiled at the two kids shortly before hitting the ground alongside the skeleton he had taken down.

"Don't be so reckless next time Senpai!" Mash warned her master while knocking out other skeletons nearby with her shield.

"Yeah I know, I know. But it has its upsides sometimes." Ritsuka said torwards Mash,not paying enough attetion that the skeleton lying besides him took advantage of the distraction to try and slash the human quickly.

However another sword was way quicker than that of the skeleton and ended up hitting the skeleton on his head,putting and end to the monster.

It was the girl.

"Thank you for helping us!" She said to Ritsuka.

"Well you could say we're even now." Ritsuka said happily,standing up from the ground. "But thank me later. There's still more to deal with!" Ritsuka made clear of the remaining enemies around them that the others were fighting.

The girl nod in agreement and went to help the others as Ritsuka stayed with the boy.


With Cú spell,the last of the skeletons had been finished,finally giving some rest to the group who went to the center of the crater in order to reagroup.

"Guess that was all of them." Mash confirmed to the rest.

The boy went to hug the girl.

"I thought we would be dead! I-I was so scared of dying sis!" The boy hold tight to the girl,almost crying again.

"There,there. It's over now. Those monsters are gone." The girl calmed down the other kid.

"So you don't seem to be locals,do you?" Ritsuka asked to the two kids, knowing that the answer would most definatly be a 'no'.

"You really don't think clearly Ritsuka Fujimaru." Olga insulted Ritsuka. "How in your mind this destroyed city of Fuyuki,that has no inhabitant apart from the monsters we just fought and the servants, would have two kids surviving in it with one of them somehow just knowing how to fight with a sword?"

Responding to Olga's critic, Ritsuka took a step back and raised a bit both hands. "Hey in my defense,this isn't the Fuyuki we know so it could be different."

"I have to agree with him. That's a good point." Cú had taken Ritsuka's side.

Olga sighed in frustration. "Honestly you two..."

"As much as I think this white haired woman looks insufferable,I have to say that we indeed are not from here." The girl gave the obvious answer while ignoring Olga mean gaze at her.

"That's better than nothing. "Mash said with a warm smile to the two kids. "You two are quite identical. I also heard the boy calling you 'sis'. Are you-"

"Y-yes. We-we are siblings." The boy spoke,still a bit nervous around the people he just met. But his sister was the opposite. She smiled brightly and put her arm around his brother's neck.

"I guess this is time for introduction heh? My name's Nala. And this scaredy cat right here is my twin brother Peko! Nice to meet you."

"H-Hi. Pleasure to meet you." Peko smiled sheepishly.

"Nice to meet you Nala and Peko. My name's Mash Kyrielight." The shielder offered her hand for a shake wich the kids done so, Nala more openly than Peko.

Ritsuka approached to the trio. "Hi there! Name's Ritsuka Fuji-" But before he could finish, Peko hugged the master of humanity thigtly around his waist.

"Thank you for saving us! Thank you! Thank you so much!" The boy said, displaying all the gratitude he could show.

"H-hey. One 'thank you' is enough." Ritsuka said nervously smilling. "You are safe now. Don't need to be scared anymore." Ritsuka could only imagine what this child had been through to be thanking him so much. Perhaps it was simply because of being a kid in a awful place like this.

"Well safe or not,I have to thank you as well. We might have been goners if it wasn't for you." Nala gently pushed Peko away and shaked hands with Ritsuka.

"Just doing what I think was right." Ritsuka saw that Nala was the brave and social one of the pair. And also knew how to fight. These two siblings were really opposite from each other in personalities.

"Still you could have ended up killed. You are not only reckless,but dumb too." Olga critizised Ritsuka once again.

Nala looked at Olga with a mean gaze before turning her head to Ritsuka. "Is she always bossy and grumpy?" Olga hold her tongue,trying to not verbally lash out at Nala.

"Hmm,sometimes. But you should still thank her. It may be hard to believe it, but she was the first one to run to this crater has soon as she heard someone was in danger." Ritsuka told Nala, giving a bit of credit to Olga.

"Huh? Really?" Nala asked to wich Ritsuka just nod. The silent answer made the girl reconsider her attitude torwards the older woman.

"Sorry for that then,I guess. You have a good heart if what Ritsuka's saying is true." Nala went torwards Olga to shake hands, admitting she judged her wrong.

"Hope we can get in better terms."

The director of Chaldea was taken a bit by surprise at the action of Ritsuka defending her and Nala apologizing immediatly after insulting her.

"S-sure! My name is Olga Marie. I forgive your sad attitude back there. But please, learn to hold your tongue next time." And with that,they both shaked hands.

"I'd say that's impossible." Peko reached nearby Olga to shake hands with her as well.

"My sister has quite a sharp tongue. It's nice to meet you as well."

"The same goes for you. Good to see you and your sister are both safe." Olga showed a little smirk. "At least this one seems educated."

With that, Cú was the only who had to introduce himself to the kids.

"Yo! Cú Chulainn here. Good to meet you two." He said relaxed and happily, standing a few feet away from Peko and Nala.

"You're the one with those sick magic spells right? It was damn cool!" Nala complimented the caster's spells.

"Oh, no need to say that kiddo. My magic isn't that fascinating compared with other people." Cú tried to stay modest.

"Well for me that was amazing!"

"Hahaha. If you say so."

"Fou fou." Fou came from Mash's shoulder and walked right next to the two kids.

"Hm? I-Is that some kind of mixture of rabbit and cat?" Peko asked confused.

"Fou fou." Fou looked a bit displeased at Peko's view on the animal.

"Hehehe. I don't blame you if you don't know it species." Mash grabed Fou. "Neither we know. It's a magical creature that appeard just one day."

"Wow! That looks quite incredible!" Peko replied. "Hmm...Can I pat him?" Peko asked a bit relutantly.

"Hehe. Of course you can. He isn't agressive. His name is Fou." Mash handed Fou to Peko who started to pat him. Peko seemed more calm now.

"Hey! Let me pat him too!" Nala rushed to her brother who after some seconds passed Fou to her.

"He's fluffy. And cute as well." Nala stroked Fou's fur. The creature was liking it.

Nala let Fou out of her grasp and he went again back to Mash.

"Now that we've introduced to each other I think we should proceed again." Cú reminded everyone in the group of their goal. "The mountain isn't too far ahead."

The group minus Nala and Peko nodded in agreement.

"Sure! But before that..." Ritsuka stared at the two white haired kids. "Peko,Nala, where did you came from?" The master of humanity didn't realized the gravity of the question he had just made.

"Huh?..." Peko and Nala looked puzzled at Ritsuka.

"W-where...did we came from?" Peko said in a low tone, his face looking pale.

"Something's wrong? Peko, Nala?" Mash was a bit worried by the suspense surrounding the two kids.

"We..." Nala spoked in a dread tone as she wore an expression like she had just seen a ghost. "We don't remember."

Her answer shocked the entire group.

"What!? You don't remember your home?" Olga was perplexed.

"We-"

"Hrghrr"

Nala was interrupted when a painful grunt came out from Peko as the white haired boy was holding his head in agony and falling to his knees.

"Ahrgg...It hurts! It hurts!" Peko screamed in pain making Nala immediatly worried and everyone else rush torwards the two.

"Peko what's wrong?! Are you ok?!" Nala hold her bother by the shoulders but she was immediatly shoved aside by Peko.

"Peko,stay strong!" Ritsuka exclaimed, trying to descalate the situation.

"Have you seen what you did?!" Olga shouted at Ritsuka who didn't take it easy this time.

"Oh! So this is my fault as well?!" Ritsuka shouted back.

"Please stop you two! This situation is already dire as it is! Peko needs our help now!" Mash called Ritsuka and Olga to reason, stopping what would be a squabble beetween them.

And it was true that Peko was indeed in a great pain,now lying on the ground.

"Tell me what is it Peko! Please!" Nala kneeled down near her brother as the headache on the boy would grow.

In Peko's mind, everything was hazy and dark. Static images passing at light speed through is vision. The boy just didn't know what they could possibly mean.

"Hallways in flames..."

"Darkness...everywhere..."

"...A beast..."

" ...Dad...dad...dad,dad,dad,dad,dad,dad."

And the pain had reached to it's climax.

"DAAAAAAAAAAAAAAAAD!" Peko screamed as loudly as his lungs would allow him to the red sky, making everyone around him to startle.

Now in a weak state, Peko felt his head more lightly than ever,his vision getting tired and confused. The sight of Nala calling his name as the eyes would slowly close, was the last thing Peko saw before falling unconscious.

"Where...did I came from?"

To be continued...


And that's it for chapter 1 of my new series that I always thought about writing it.

Was I a bit too mean with Olga? Perhaps,but her personality in the start of the game also doesn't help her that much.

Fortunately next chapter won't have that much of Olga slander.

And yes Peko and Nala are the oc's of my fanfiction here. You can see already the difference beetween the two.

Nala is the extroverted and brave one while Peko is the introverted and scared. A warning that Peko will be a wimp in this series first chapters but he'll gradually evolve in the course of the series. So yeah, if you don't like him already that's okay. He is supposed to be like that in the beggining.

Now I'll try to give as much personality as I can to Ritsuka since,you know,he kinda doesn't have much in the first saga of FGO. So yeah,Ritsuka is still a main character in this fanfiction and will still have an important role. My objective isn't to overshadow him by the existence of Nala and Peko but to all get the mc spotlight.

Well that's all I wanted to say and see you next time for chapter 2. Peace!
