Chapter Text
They immediately started making a plan to get back but the main issue was they had no clue how to get back. They just woke up there and Nagisa teleported them back so they didn’t know how to get there.
Luckily they had Ritsu and she used the data from where they were to get a location. Korosensei explained the plan “ So we need to get in and we have to try to talk to Nagisa. We know he has some trauma from past school experiences as he told us.”
Kayano raised her hand “ Yeah that’s why he changed his appearance before transferring.” Korosensei nodded “ Correct. We need to make sure nothing unsafe is happening with Reaper because he said he gets mad easily and I don’t want to make assumptions but he always where’s long sleeves and has a scar on his eye brow. I am just a little concerned.”
Isogai raised his hand “ So you think Reaper might be like hurting him to get him to stay or he might be hurting himself in some way?” Korosensei nodded slightly “ Yes but I’m not certain so don’t start with that when we see him.” The class nodded and all stood up to get ready. They all put on their gray suits and got everything they needed and set off to their location. It was actually a long walk they weren’t expecting it to take that long, they assumed Nagisa used his power to get to school every day because it was way faster than walking.
It took them a solid 20 minutes to get to the house, well more like mansion. The house was huge. How were they going to get in unnoticed. They eventually found a back way into the house and they went up the stairs to the top floor. They remembered where his room was.
When they opened the door to his room he wasn’t there. Then they heard yelling a few doors down and went to investigate. They followed the yelling until they opened the doors to see Reaper making wild jesters with his hands while yelling at Nagisa who looked like he would rather be anywhere else. “ I CANT BELIEVE YOU HOW COULD YOU BE SO CARELESS. SOMEONE COULD HAVE SEEN YOU.” He turned and grabbed his face. “ Hey look at me when I’m talking.” He let go and walked over to a wall of weapons. “Maybe this will help you learn your lesson, the one thing that can truly hurt you.” He got out this lamp looking thing. “ Roll up your sleeve.”
Nagisa’s eyes widened but he just did as told and even though the class was far away they managed to see his wrist and part of his forearm and it was safe to say they didn’t like what they saw. Reaper turned on the contraption and it lit up very bright he put it directly on Nagisa’s arm for like 4 minutes. They watched as Nagisa flinched when he put it on and it looked like it hurt a lot the more time passed. After 4 minutes Reaper removed it. “ Go to your room and don’t do it again.” He left and Nagisa stood there for a solid 45 seconds and then shadow traveled to his room.
The class ran to his room. When they open the door in they found him sitting on his bed once again but this time playing the guitar. He was actually really good. This time he noticed them after like a minute. “ What are you doing here?” Korosensei walked over “ Are you ok what did he just do?” Nagisa seemed to shrink into the corner “ You saw that?” Everyone nodded. Kayano walked in the edge of the bed “ What was it.” Nagisa sighed “ It was a military grade flashlight 10 times stronger than a normal light. I’m sensitive to light because of my power. That’s why I always look super tired when the sun is out. It’s kinda the only thing that really hurts me.” He pulled up his sleeve to reveal a dark red circular mark on his arm.
The whole class froze. Karasuma asked “ What happened to your wrists?!” Nagisa froze his mouth opened and closed like he didn’t know what to say. He pulled his arm back fast “ N-nothing.” Karma clinched his fists “ That wasn’t nothing and you know it.” Korosensei used a tentacle to grab his wrists “ Hey no don’t-“ Korosensei didn’t listen and he pulled his sleeve to reveal his wrist it had deep scars on it they were perfectly inlined but not fresh at all. “ d-did you?” Nagisa tried to pull away “ n-no I- just let go.” He had tears in his eyes the class saw no matter how hard he tried to hide them. “ I-I don’t anymore Reaper made me promise.” He used his other hand to get out of his grip.
Korosensei crossed his arms “ Still what we just saw Reaper do was abuse and very illegal. You need to be taken out of Reapers care now.” Nagisa shook his head “ No I already know what’s gonna happen then. I get dumped in some trashy foster home that I would end up running away from and get my own place. It’s better here even if it still sucks.” He crossed his arms “ Literally no family in their right mind wants a kid with freaky powers I found that out a long time ago.” He disappeared into his shadow and reappeared behind them “ Seriously you should just leave. I have a mission anyway.” He grabbed and few things from the wall and threw on an old black hoddie with a few holes in it and snapped his fingers.
The class was teleported outside along with Nagisa this time. He started walking the class followed him. He never looked back but there were a few times he would call out behind him “Why are you still following me?” Or “ I am fine really you can leave.” It was never too loud but just enough so the class could hear.
They walked until Nagisa got pulled into and alley they all ran to try and help but Nagisa was fine. They watched him pull out a small stick. He pressed a button and it got bigger and turned into a synth. “ Wrong choice.” He immediately started fighting the people that grabbed him were no amateurs either they knew how to fight. They almost got Nagisa a few times but Nagisa just used his power and eventually he brought them all down. Except for one the boss it seemed. His face was already covered in blood and he looked terrifying so he just walked over and the boss kneeled but the class saw the knife he was holding. Once Nagisa was close enough the man tried to attack but Nagisa just dodged and stabbed his side with his synth. He took it out and swung it a little to get the blood off and collapsed it. The class was standing there with their jaws on the floor. Nagisa walked past them with his hands in his pockets. The class snapped out of it and ran after him. Karma called out “ So you know how to use a synth?” Nagisa nodded “ I know how to use every weapon I just like using a synth it’s my favorite. Plus it looks super cool.” The class couldn’t even argue because while fighting he looked so bad ass it wasn’t even funny.
He eventually got back to the house and was about shadow travel in when Karasuma put an hand on his shoulder. He didn’t even turn around his voice was barely above a whisper “ I really can’t leave I think he would actually kill me. He’s an ass hole like that.”
He walked forward and used the shadow as a cover as he walked in the gate. As soon as he got to the door though he seemed to change his mind. He dropped the shadow and went through it just to be brought back outside with the class. “ I think I’ll stay out a bit longer.” He turned and walked the other way he shadow travelled every few steps for fun. The class had to admit he had great control of his power. Karasuma asked as they walked “ You have good control of your power what else can it do?” Nagisa glanced back “ Thanks I use it a lot that’s why. I can travel through them to different places, bend them to do things I want and I can hide in them. It’s not hard but I can do most things in the shadows that’s why I hate when it’s bright out.”
He shadow travelled to a building ledge. The class saw and also climbed up to meet him at the top which he was expecting at this point. He knew they wouldn’t stop until he came back but he knew Reaper would kill him so he would stay. Better than having to avoid him trying to kill you forever. It’s better if he only gets a little mad.
The two teachers went over and sat with him. “ So wanna tell us the real reason why you won’t come back or should I start guessing?” Nagisa pulled his knees to his chest “ I- it’s just …. Easier. Also how are none of you scared of me. Most people don’t wanna come within a foot of me once they find out about my power let alone you just watch me murder like 7 people…. So why are you still here? You should be running away terrified by now. You even came back.” He used his power to twirl his shadow around his finger.
Kayano walked over and sat behind him “ That’s because we actually know you. We know you wouldn’t do anything bad unless absolutely necessary and your power is cool.” She paused and Karma continued “ And why would you think we cared about you being a real assassin if anything that helps us.” He walked over and put his hands in his hair “ So stop running away and come back to class.” The whole class agreed they needed him in their class. He was family and a valued member of their class.
Nagisa giggled which the class had assumed was the first time he laughed since he came back to Reaper, which it was but Nagisa wasn’t going to say that. He looked out across the now rising sun “ Ok I’ll trust you but Reaper is going to kill me for this.” Karasuma smiled “ No he’s not I made a few calls he will be taken to prison. I’m also having them get your stuff because I assume you don’t wanna go back.” ” Nagisa’s eyes widened “ Really Omg that is so amazing. And you assume correct. Can we go now the sun is hurting me.”
Korosensei immediately went into protection mode “ Oh my gosh!!! Why didn’t you say anything we need to get you out of the sun now!!!! Come on class help me cover the sun!” Nagisa just started laughing “ Hahahaha or I could just.” He snapped his fingers and they were all immediately brought to the front of the class room. The class started laughing. They finally succeeded even though it took a really long time and a lot of convincing, Nagisa could be really stubborn when he wanted to be.
“ By the way I think you forgot I’m 4 grades ahead of you.” The class paused they forgot about that. Korosensei laughed “ That’s fine I can make a separate lesson plan or you could just help around the class.” Nagisa shrugged “ Or I could do both.” Korosensei nodded “ I was hoping you would say that.”
The class walked in Nagisa’s stuff was already there sitting on his desk. “ Wow you work fast.” Karasuma smirked “ That’s the ministry of defense for you.” He paused and then got a more serious look on his face “ But we need to talk about the injuries.” Nagisa got quiet and grabbed his wrist “ I said it was fine. I haven’t done that in 2 years. Once Reaper found out he made me stop because I couldn’t get hurt, I was his most valuable assassin. He would literally put the light on my arm to get me to stop so I promise I’m fine.” Korosensei walked over “ You know we need to at least treat the burn from yesterday.” Nagisa sighed “ Fine but only the burn.”
He pulled off his hoodie and then rolled up his sweater. The class obviously saw the scars but He covered them with his hands in his after he rolled his sleeve. “ Ok you saw it. Can I just..” He walked over to a corner of the room and put his hands in his over the burn. After a few seconds he took his hands off and the class only saw a faint circle where the burn was. Karasuma walked up and brushed his finger over it “ How did you do that?” Nagisa shrugged “ If I focus enough I can heal myself with the shadows. It is pretty easy as long as I can concentrate I can heal other people too.”
Korosensei crossed his arms “ What else can you do with your powers?” Nagisa looked up still kinda surprised they wanted to hear about his powers “ Well I can travel through them, I can go as far as I want as long as there is some shadow. I can heal with them and I can control them it won’t do anything to the person but it feels kinda weird from what I have been told. OH I can also make the shadows into things that feel solid like my synth I have one but I can also make it out of shadows that one is harder to fight with though.”
The class was shocked they all yelled variations of “ And you didn’t tell us!?” Nagisa giggled “ Well I honestly expected you to be like super scared and not want to be near me… I mean that’s what happened last time I went to school.” Karma and Kayano looked at each other karma walked up to him and flicked his head. Nagisa grabbed his head “ Ow what was that for?” “ For being stupid we are not those kids and we wouldn’t do that. Got it.” Nagisa gave a slight smile and rolled his eyes“ Yeah thanks.”
He was back and he wasn’t leaving again not on the classes watch. The first week they kept an eye on him but he settled in fine after some encouragement from the class. It was clear the past had a big impact on him. The class helped him through it and things are back to normal. Well as normal as it can be now with there octopus teacher and basically a shadow bender. Kayano came up with the name and Nagisa likes it so that’s what they call it. Nagisa just calls in shadow travel because that’s what he uses it for. They were all together again and the weren’t going to let Nagisa get hurt again they were not going to be his fear from childhood they would be better then them. They are his friends and they truly care about him. So does he.
