All might pov
The week for y/n to go intern with grand Torino starts today
All might: y/n! Time to get up!!
I didn't hear him grumble at me like usual, I went upstairs and opened his bedroom door
All might: y/n?!
He wasn't there, where is he?! I immediately rang aizawa
All might: aizawa! Do you know where y/n is?!
Aizawa: no, why what's wrong?
All might: he's not in the house
Aizawa: oh shit...
All might: what should I do?!
Aizawa: come to UA, me and nezu will help you find him
All might: okay... Okay... I'm on my way
Y/n pov
I stood tall ontop of some buildings and looked out at the city of hosu
Y/n: never again...
I heard some wind noise behind me and turned around
Y/n: hello sir...
Grand Torino: boy.. what are you doing here, I told you there are no more leads on all for one
Y/n: don't lie to me
Grand Torino: I'm not-
Y/n: yes you are!
Grand Torino: boy, what's happened to you...
Y/n: he's in my head! I can't get rid of him! He's still out there I know it!! I need to find him and bring Him to justice!!
Grand Torino: it's not your place to do so boy!
Y/n: I swore upon Nana that I'd end his evil on this world!! No matter what!!!
I jumped down and blasted off into the sky, I looked around and saw someone else who's on my shit list
Y/n: stain...
I blasted down behind him and grabbed his shoulder
Y/n: put this man down!
Stain: and who are you to give me orders... No way.. your him!
He dropped the hero who then ran away, stain grinned and drew his sword
Stain: finally, my gamble payed off, I knew you were his son as soon as I saw you all those years ago
Y/n: what are you on about?
He grinned again and tried slicing my chest open, I jumped back at the last second and went to attack him but a portal appeared and he was dragged through, I instantly recognized who's it was
Y/n: no... Damn you!! SHIGARAKI!!!!
All might pov
I got to UA and rushed to the teachers lounge
All might: I am here!
Nezu: there you are, now, aizawa said y/n's missing?
All might: yes sir, I went to wake him up to get ready for his week with grand Torino, and he wasn't in his room or anywhere in the house, I'm worried!
Nezu: calm down my friend, we will find your son, have you contacted grand Torino?
All might: not yet sir...
Nezu: well do so, he is your mentor after all...
Nezu and aizawa began talking between themselves so I walked away and called grand Torino
Y/n pov
I kneeled atop a building and looked out towards the city
y/n: stain got away cause of fucking shigaraki!
i looked out and saw heroes patrolling around hosu
y/n: I envy them sometimes... having no need to worry, not needing to deal with the media...
grandtorino: boy... I know the weight on your shoulders... I know what you deal with, I have sworn that I will assist you in your hero career no matter what...
he walked up behind me and grabbed my shoulder
grand torino: but its still not your place to deal with villains
y/n: and yet I still work harder than most of the heroes... I was the one to bring down the biggest villain in history
grand torino: you did, but still, there are limits to what you can do...
y/n: I know...
I stood up and looked down at the streets, as the day passed and day turned to night, the streets became more active, more heroes and more civilians, as the streets were filled the noise of the city became louder and louder, I jumped from rooftop to rooftop looking for signs of stain and shigaraki and him...
Y/n: I'm not getting anywhere- what?!
???: GAHHH!!!!
I snapped my head in the direction of the scream and dashed towards it, smashing down on the ground behind where scream came from, it came from an alleyway, but before I could pursue it I got hit by a flying car, stopping it from doing anymore damage I looked at what had thrown it and saw a nomu
Y/n: tch! You again...
I threw the car at it and dashed forward, tackling it to the ground and pinning it down, I noticed it's appearance, it was vastly different than the one from the USJ, it was far weaker as well but before I could defeat it I got clawed from behind and thrown backwards by another nomu, this one was grey and had wings, it dove at me and gripped my shoulders with its claws
Y/n: not again!!
It took off and took us higher than the clouds, then another one appeared and they began fighting, both trying to get me, I used this opportunity and grabbed the one that had a hold of me and crushed it's legs making it lose its grip on me, I began free falling with the two chasing me, I punched downwards sending me up past the nomu, I dashed down at them both and grabbed them by their necks, kicking my legs backwards, I bolted down towards the streets of hosu, noticing a clearing, I altered my course and collided with the ground instantly defeating the nomu, I got out of the crater and ran back to the alleyway where I heard the scream and saw izuku, Lida and todoroki all fighting stain, I saw native on the ground wounded, when stain looked up at me his face turned to a twisted smile
Stain: son of all might!
This made my three classmates turn towards me, all having wide eyes of shock, I walked past them and glared at stain
Y/n: stain...
Stain: haha... Hahaha!!! HAHAHAHAHAHA!!! I haven't felt like this in years!!!! Fight me!!!!!
He rushed at me with his blades drawn, I narrowly dodged his attacks, I took in his appearance, he was battered, but so were my classmates, I grabbed his arm and threw him backwards
y/n: you are in no condition to fight, give up now! and turn yourself in!!
stain: like hell...
y/n: tch! for FUCK SAKE! I'M TRYING TO HELP YOU HERE! TURN YOURSELF IN NOW! AND YOU MIGHT GET A SHORTER SENTENCE!
stain: LIKE HELL I'D SUBMIT TO YOU FILFY HEROES!!!!
y/n: RAHHHHH!!!!!
I punched him so hard in his gut that his eyes went white and he fell forward, passing out, I looked at my classmates and saw they were wide eyed
y/n: report back to your heroes...
Midoryia: y-y/n
Y/n: report back to gran Torino now, I don't want a lecture off the old man
I walked away from the scene and back into the street, I saw all for one walk Infront of me
All for one: look at this destruction, I'm impressed, didn't think tomura could do it on his own, of course, he had my help...
Y/n: what?!
All for one: haha...
He disappeared into mist leaving me confused and angry
Y/n: I will get to the bottom of this..
