The Vigilante That Is A Litual Walking Arsinal

First Day Back To School

Izuku POV

I was standing outside of class 1-A when I heard my name called and I walked in and Kachaan noticed me right away and stood up. But I ignored him and walked up front to introduce myself. "Hello my name is Izuku Midoriya and I will be in your class from now on, I hope we can get along" I said showing a fake smile.

Kacchan came up to me and attempted to attack but failed when I grabbed him and slammed him against the chalkboard.

1-B

We were having a lesson when we heard a big bang

"What are they doing making such a commotion" Kendo said annoyed.

Back to 1-A Izuku POV

After I slammed him against the wall, "Behave ok" I then let go and he pouted over to his seat and sat down as did I behind him.

"Ok now that that's over we can start" he said and he mentions the sports festival and how it's a good opportunity to get scouted.

Time skip to lunch

I was sitting eating lunch when Kirishima, Kaminari, and Mina came over. "Hi can we sit here" I said sure why not. They then asked how I know Bakugo then said person sat down beside me.

Kirishima asked if how I knew him and I simply tapped my left hand on the table instead of making a knocking sound it made a tink confusing them, "we knew each other as kids, and I am the only thing keeping him in school" I said confusing them more and him until it clicked and he was scared shitless. I was about to say something else when I noticed the bullet on his keychain connected to the hole him his uniform pocket.

'He only puts things that are memorable on that thing so why does he have the bullet on the keychain' I thought and he noticed I was looking at his personal keychain. I then looked at him then tried to change the subject.

I was knocked out of my thoughts when I was asked, "wait why are you the only thing keeping Bakugo hero Midoriya" the pink girl now known as Mina asked.

I smiled, "are you guys this morons friends" I asked and they nodded.

Kirishima POV

'He's talking like Bakubro is a piece of crap' I thought as he continued to talk and Bakugo was just accepting it. Until I had enough until he said something that made my scared and curious.

"You guys want to know something that has to stay secret but you guys have to keep it to yourself," he said and I could tell my hot headed friend had enough.

"DON'T YOU DO IT IZUKU" he practically yelled.

He just had a smug smile on his face, "ok I will let you tell them when your ready but now that they know something is up how long can you keep it hidden my old friend" he said before he tapped his left arm and I could see my friend was irritated.

Midoriya then got up and threw the contents on his lunch try away, I then looked at my friend. "I'll tell you guys eventually is that an ok answer" I agreed so did, Mina, Sero but our blond friend was a little to oblivious well that's what we were expecting to happen.

"Yo Bakugo you can take you time no hurry" usually I'm the sympathetic one.

My friend actually smiled at the comment and left leaving us to think in awkward silence.

I decided to break the silence, "if it's something he couldn't make a loud excuse to avoid answering it has to be serious," I said as I watched him walk out of the cafeteria with a tear going down his face, "definitely."

Izuku POV

'That should keep him on edge' I thought with and evil smile.

Later during heroics

We were in class All Might came in, 'all the teachers but none of the students but I might change that after today' I said in my head considering this class is called heroics.

"All right class put on your costumes and meet on the training ground and your Midoriya you can wear your costume" he then rushed out and I walked to the locker room and changed because my costume is in my bag.

After everyone changed

Kirishima POV

We were walking to the training field and saw All Might talking to someone. It took about fifteen and I stopped in my tracks and activated my quirk confusing everyone but I wasn't expecting a complement.

"Very good you have some promising students All Might already one had noticed that something or someone is here that shouldn't be here" I then saw the figure turned around and I wasn't expecting the number one vigilante.

I didn't deactivate my quirk even when Iida asked a question, "May I ask a question" All Might said go ahead, "what is a vigilante doing here sir" and no one moved from a battle stance.

Izuku POV

'Good very promising, Kirishima would make a good hero he's always on his toes he was the moment I walked into that room and threw Kaachan against and pinned him to the wall' I observed.

I then told All Might I am impressed and he looked surprised and we all stood there readying for battle until I took of my mask shocking everyone. Well except Kaachan.

"Hello everyone my name is Arsenal and I will be you opponent today, sooooo you are in a world of hurt today" I say as I martialize a green glowing handgun and twirled it around my pointer finger.

But they didn't get it so All Might had to take over as I put my mask back on and loaded my gun with non lethal bullets because I am fighting kids.

"You are participating in one on one battles with our young vigilante student it would be good training for the sports festival since he will be in it but he won't be able to do any internships" he said and I nodded.

Then something happened I wasn't expecting happened, also shocking everyone I had to quickly put up a giant metal shield by making my left had like a big wall to block the extreme amount of force from Kacchans attack. 'That was close, to close' I thought as I turned my arm back into just an arm shocking everyone that my arm wasn't a real arm. "Sneak attack your specialty" I said looking at my old friend with a smoking gauntlet.

He sighed, "worth a shot eh Deku not bad" I flinched behind me mask.

I took off my mask and I could tell they sensed my aura changed real quick, "I'm not that small one armed kid that you left Kaachan, I'm not defenseless" he flinched when I mentioned it but I did it to make a point he gave me the nickname because I was making a point. I then martialized a gun, "YOU WANT TO FIGHT THEN COME AT ME" I yelled even scaring the teacher.

He looked a little intimidated but it didn't stop him. He took a deep breath, "it is a hero's job to stop the villains it's what you said once right. So I will try and attempt that after wards" he said scared and I calmed down because he is chicken.

I twitched because I actually expected him to come at me. I sighed, "fine whos first" I said.

That was part 1
