The Vigilante That Is A Litual Walking Arsinal

The Vigilante Has Been Captured and Now School

Izuku POV

I was running from rooftop to rooftop trying to get away from heros, "man they are persistent" I said trying to lose them by car hopping again as I did with All Might but it didn't work. Then out of nowhere I had to cover my ears while falling from a building, "so loud" I said, hoping it would stop. When it did I got up and tried to pull a gun on them until fell in pain.

Aizawa POV

I along with Hizashi were in pursuit of Arsenal when Mic shouted and he fell from atop a building and hit the ground hard, 'that has to hurt' I thought looking. Then as I saw he was about to pull a fast one by pulling a gun. I activated my quirk but at the same time he fell over in pain and then his arm started disappearing and he was screaming in pain. I stopped my quirk and his arm came back while me and Mic looked at each other.

I then made a modification to the handcuffs while I had him unconscious in my scarf. I put a regular cuff on his left wrist and quirk suppression on his right and took him to the station.

Izuku POV

I was waking up slowly and when I tried to stretch I was handcuffed to an interrogation table, 'so I got caught huh' I thought looking around until the door open revealing, Tsukauchi aka detective lie detector. "Congrats you caught a minor" he wasn't at all shocked it was like he already figured it out.

"We also caught the number one vigilante" he said but looked sad he couldn't put me in jail because of my age. "I need you to answer some questions and then we will decide what to do with you" I agreed not like I had a choice.

"But thank you for using quirk suppression on my right hand and not my left otherwise I would have bled out by now" I said and he was shocked even more when I knocked on the metal table with my metal arm, "and I'm not a cyborg so relax" I let out a breath.

Tsukauchi POV

"Ok first question why did you become a vigilante" I asked.

"Because as soon as my bully said he wanted to be a hero I chose a different path and now I'm here" he said truthfully.

"Ok what's your quirk" I asked again slowly getting personal.

"Weapon materialization and manipulation I can make any weapon appear from daggers, guns, missiles, bombs, etc. but the limit is my imagination. I also can control bullets in the air after they left the gun or throw them in the air and control them that way" he said still telling the truth.

"Ok what's your name"

"Izuku Midoriya" he said not lying.

"Good what happened to your arm" he froze really not wanting to tell me. "Next question please" he said. "Ok how long have you had it" I asked calmly.

"I had it since I was four because my mom told me not to show anyone so when someone asked I said I was quirkless" he said calming down from the last question.

Then I hit him with the big one, "what is your connection to Katsuki Bakugou" he froze again then spoke.

"If I tell you, he will be under my protection that is the terms of answering this question so he doesn't get into trouble" he surprised me there. "I have to talk to the school and his parents" I said and he understood and motioned me out of the door and said he would answer the question when he gets his answer but added, "meaning you can not arrest him" that made me look back he had and emotionless face.

I called Nezu but not his mother and he came over right away but with All Might. "What seems to be the problem detective" he asked then I motioned to the interrogation room and he opened the door and we walked in and he sat at the table and me by the wall I could still hear and ask questions I was just not in the discussion right now which I used to with this thing of a principal.

Nezus POV

"So I understand that you want to put a student of ours under your protection over a question" he nodded and said, "because this is a difficult question to answer and I never showed or told anyone and I guess if you said yes, then I would have to break a deal I made with him and the reason I want to do this deal is because I don't want him to be kicked out of his dream school he wants to be the number one hero who am I to stop him. Anyway I don't want him kicked out" he said and I understood and nodded.

Izuku POV

I took a deep breath, and asked for the cuffs off, "relax the disappearing is just running really fast and what's the point there's the principal of U.A. and All Might right outside the door even I wouldn't get out unscathed" I said and he took them off and I took my shirt off. Then I summoned a pain nullifier gun and gave it to one of them the detective took it because apparently Nezu doesn't like guns. I put my hand on a switch on my shoulder and a voice was heard.

"Now activating sealing so that there is no blood loss" they here surprised.

About ten minutes later, "alright detective you can fire nothing will happen I turned the gun on silent so no one runs in here" I said and he was hesitant but pulled the trigger. "Ok now since I can't feel pain I can show you" I said as I turned the switch and removed my entire arm all the way from my shoulder down. When I gave it the them they inspected it then looked at my wound the entirety of my original arm was gone. They only asked one question.

"What happened" they asked in a sad tone.

Nezu POV

"What happened" we both said worried.

He tilted his head to the side, "I think you actually already know, though I am grateful he felt sorry" that got me.

Flashback

"I owe it to him" he then looked at us with determination in his eyes, "I did something that haunts me that's why I can't tell you," he said then I dismissed him.

Flashback end

I looked at the detective and he went pale, 'he remembered to' I thought looking inside the arm through the hole in the shoulder and saw a nightmare. There were nerves, sprawled throughout the thing so the arm would react when he wanted it to, 'he my not be a robot but if he had anything else like this on him I would consider him one' I thought looking at it then gave to him before I threw chunks.

Izuku POV

They gave me my arm back and I connected it and opened the shoulder cavity back up the nerves would reattach to each other. They then asked how it works, "basically I always have my quirk active so I broke the limit when I was eight, so I don't get tired from using it over and over," I said answering their question then I turned serious, "now our deal I want to change it up I want in class 1-A in the hero class so I can make sure you don't try anything" I said and they looked at each other and then Nezu made a call.

I then heard, "your lucky you would be in jail" I nodded telling him I know. "Also you should get ready literally once you get there it's to the sports festival" the detective said.

"Ok so it's up to them I will be surprised if the let me compete in the festival" just as I said that the door opened revealing the principal.

"Welcome the U.A. Izuku Midoriya" he said to me and I smiled.

"Thanks and I'm guess-" I was cut off, "you can compete you just can't do any internships" he said to me, surprisingly.

"Ok" I said dumbfounded.

"Go to U.A. not in your costume I'm pretty sure only one person will recognize you" he said and I nodded. "You will also stay with Eraser Head considering he is the only one that can stop you"  and I nodded. He opened the door.

The detective said, "get the stuff from where you were staying and he will meet you outside the station" I nodded and zipped home.

'This will be eventful' I thought.
