This is a request!

"So, (Y/n), how are we doing today?" Shiro asked with a smug look on his face. She didn't say anything, knowing it wasn't worth wasting her breath to answer such a horrible man. "Come now, don't be like that. I thought you wanted to be strong." Of course she wanted to be strong, who doesn't? Thoughts of doubts have taken over her mind. They were all about wether this was the best path to get strong or not.

"Well since you're acting that this today," he takes a bottle labeled "xxx burn" and opens it up. "I will just experiment even more today. I'm sure Itona would be happy to see someone else other than myself. I have this feeling that he will behave even worse than you." Luckily, he never put whatever is in that bottle on her face or neck.

Itona was the boy Shiro would talk about from time to time. From what he has told (Y/n), he is another boy her age who was experimented. She always wanted to meet him and just talk to another person. The other person both (Y/n) and Itona would see was Shiro. Shiro was never kind to them, he ruled with an iron fist.

"Maybe you will meet today." Shiro chuckles, "that will be very interesting. He is on break right now so you won't be able to meet any time soon."

That's what Shiro always said every time he mentioned Itona. So every time Itona was experimented on, (Y/n) would be on break. Which leads to Tone being on break every time (Y/n) is being experimented on.

"Then again you will never be friends," he laughed, "it would never work out."

(Y/n) didn't believe that. If they were both being experimented on then they may have the same reason to want this power. Then again, maybe he wants to kill this "Koro Sensei" if he knows who that is.

"By the way, you will be enrolled in a junior high starting tomorrow. Make sure you get plenty of rest tonight." Shiro said, "you will have a chance to kill Koro Sensei when I will you too. Is that clear?"

(Y/n) nods her head, not saying a word. Knowing that speaking now would give Shira power over her. He leaves her alone for the rest of the day. "Maybe I'll see the stars today." She whispers to no one. "It's been awhile, I wonder what they look like this time of year."

----

"Today's the day. Don't mess up." Shiro said to Itona and (Y/n), who were stealing glares at each other. After hearing a little about each other almost once a week, they now have a face to go with that they have been told. "(Y/n), you will act like a normal transfer student. Do not make any friends or enemies."

"Itona mess around with the teacher, anything to throw him off guard. Then carry out the plan from there. Do anything stupid and I will remove your tentacles. Does everyone understand?"

Neither (Y/n) nor Itona say a word, they nod their heads in response.

"(Y/n), it's time. Don't mess anything up." Shiro said in a very demanding voice.

(Y/n) enters the school building after making sure no one was around to see her run out of the forest. She appears on the path leading up to the old school building. She didn't pass any students while she was walking. So when she walked into the classroom everyone was surprised to see her.

"Oh you must be the new student." A man that looked normal said. "I didn't have a chance to tell the others you were coming, sorry about that."

"That's okay." (Y/n) replied with a smile, "it's nothing to worry about." The man nods and then a women with blonde hair comes walking up to him. This gave (Y/n) a chance to slip away and into the classroom.

"Hello," a girl with green hair greeted with a smile, "are you new?"

She was told not to make any friends or enemies. Being cold wasn't the best choice of action. So what was?

"Umm hi, yes I am the new transfer student. Your teacher told me that he didn't have time to tell him." (Y/n) said with a small smile.

The rest of the class was already looking at the new girl. They didn't even know what Itona was planning. She took her seat in the back and Koro Sensei slide the classroom door open. He looked just like Shiro said he would.

"Oh a new student." Koro Sensei said and moved over to her desk with his super speed. A puzzled look as said with his body language. His facial expression did not change. "So you are not surprised by my speed. The schools principal must have told you-"

"I wouldn't be too sure about that." A voice said from the classroom door, "you never know who knows about you. Many assassins aren't very good at keeping their mouths shut." It was Shiro himself of course.

Koro Sensei looked at him, "you're too old to be the new male transfer student. Did you do-"

"Itona come on in." Shiro ordered.

Itona came into through the wall, literal. He took a seat next to mine in the back. This was our second time seeing each other. 

"Use the door!" The class yelled in both angry and shock.

"Why don't we have a little match after school, Koro Sensei? You against Itona." Shiro spoke in a calm voice. "You wouldn't want to refuse unless," he pulls out a real gun and points it at (Y/n)'s head. "You want one of your students killed. The choice is yours."

"So much for giving him a choice." A boy with red hair said, "that is a real gun after all. You must have done a lot of research on our class. Maybe you have been stalking us or-"

"That's enough Karma." Koro Sensei said to the boy with red hair."

"Fine, see you after school."  Koro Sensei replies, "now put the gun down and walk away."

Shiro lowers his gun but shoots one bullet just passed (Y/n)'s head. Getting his point across that he wasn't joking about killing her. The girl doesn't make any movements even though she tried to remain calm on the inside.

----

During gym, (Y/n) and Itona sat on the sidelines. Aka the staircase outside, watching the others practicing with their knifes.

"So you're (Y/n), Shiro talks about you a lot." Itona spoke, "so uh nice weather today."

It was their first time saying anything to each other even though they already know so much about each other. Nothing like things you would ask on a first date. Their knowledge on each other as more like pain tolerance and how the other was acting that day.

"Yeah it is. Are you really going to fight Koro Sensei?" (Y/n) asked him.

"I have to."

"Why? Because Shiro told you too?"

"To prove that I am strong. To show everyone that I am the strongest person here." Itona replies, "why else would I still be with Shiro. What are you doing with a person like Shiro."

(Y/n) shakes her head, "nothing worth talking about."

Itona tilts his head, "will you ever tell me? I know it's not something you ask someone when you just met..."

"Maybe if we see each other after this." (Y/n) says, "we can try sneaking out at night. Shiro is a very heavy sleeper, probably."

Itona nods, "it's a deal. Let's meet on the roof next week."

The two shake hands, making their first major spot to becoming friends.

When last bell rings and the classroom is transformed into a battle arena. Itona and Koro Sensei were in the middle of the desk made arena. "So it's whoever gets out of the arena first." Koro Sensei states, "fine by me."

"Itona, kill him." Shiro ordered and Itona luges for Koro Sensei. His tentacles appear and start killing the teacher, trying to slow him down.

The longer they fight, the more rage fills Itona. Shiro must know when to stop him. Koro Sensei suddenly knocks Itona out of the Arena. Luckily, the window was left open so no other damage was made to the school building.

"Looks like you lose." Karma says, "so you're not as strong as you talked yourself up to be."

Itona rises up and luges at Koro Sensei again. This fight has been going on for ten minutes now.

"(Y/n)," Shiro said gaining the girl's attention. "Tackle Itona to the ground. Do whatever it takes to stop him."

She nods and cares out Shiro's orders. Only to find out that she hurt Itona much more than a normal tackle would.

Itona screams in pain, causing (Y/n) to jump back. She sees the burn marks on his skin, a look of shock and horror take over as her facial expression.

Shiro laughs, "so the chemical does work. Your work is done, (Y/n)." He comes over to where she is and picks up Itona. "We must leave now. Unless you want to stay with everyone who thinks you're a monster now."

She knows Shiro is saying that to get into her head. And it works. Every single time.

----

A week has passed and (Y/n) makes her way up to the roof of the building her and Itona get experimented on. After a half an hour, she wonders if he will even show up.

"I did burn him after all, is he scared of me?" She whispered.

"How could I be scared of you?" Itona asks, taking a seat next to her while making (Y/n) jump. "You're so gentle and sweet. I know you didn't hurt me on purpose."

She doesn't say a word so they sit in silence. Minutes pass and (Y/n) looks up at the stars.

"Are you a stargazer?" He asks her.

"Yes, they've always been here for me. What about you?" She replies.

"Not really, I never found them to be interesting. But I will try it."

Stargazing is what brought them closer. Stargazing lead them to want to go back to that school as a student. They had a taste of what a true friend is and now they crave more. Once they were out of Shiro's control, they made sure to meet up every day and watch the stars.

Okay so I know this doesn't follow the plot line and that's because I forgot what happens here. Even reading about it on the FANDOM website (where I usually find out what I need to make one shots) I still didn't know what to do. Also I thought that making them date would be weird unless I did a time skip. But then I thought adding a time skip would be weird. Anyway I'm done explaining. I hope you guys like this one shot and I'll see you later!

LOVE YOU GUYS
