The Hero of Vengeance

Back in Town

The crashing of doors can be heard as a certain symbol of peace busts through them holding a comatose Y/N. His quirk had drained him. He wasn't used to the rage and power flowing through him.

All might: CHIYO! WHERE ARE YOU!?

Chiyo: what is it toshinor- oh no... get him to the bed, quickly!

The students were following behind him with aizawa, but of course, all might got there way before them.

Chiyo: what happened toshinori?

All might: I- I failed them... I promised them that I wouldn't let anything happen to him...

Chiyo: quit whining and tell me what happened!

All might: his quirk. The students were ambushed by villains in the usj. Somehow they managed to get in, but they brought a creature with them apparently. Something that was made to kill me... Y/N got there before I did. Shoto told me that momo was hurt by it. Y/N flew into insanity and turned into... something... he killed it... about then I made it to the usj, but I saw Y/N, or at least his quirks manifestation. He walked over to momo and somehow... he healed all her injuries. That thing turned back into Y/N and he just fell forward.

Chiyo: that's... quite a mouthful... it seems his quirk drained him. I could try to heal him, but so much stamina was lost during his transformation it seems. If I use my quirk, he might die...

All might: no no no NO!

He slams his fist against the wall leaving a hole roughly the size of his hand. Tears started to stream down his face.

All might: I promised his parents that I wouldn't let anything happen to him... I promised them that I'd guide him, keep him safe... while I was sitting back, they were being hunted, nearly killed... I'm a failure...

Chiyo: *sigh* even after all these years, you're still a huge baby.

All might: !?

Chiyo: you might not have noticed, but his quirk is simultaneously healing him. It's like those new fancy telephones. He goes to sleep to "recharge". If that makes any sense. The best we can do is hook up a couple iv's and wait.

Momo suddenly busts through the door.

Momo: IS Y/N OK? WHERE IS H-

She sees him lying in the bed and starts to cry as she runs over to him.

Momo: Y/N, please wake up!

All might: young yaoyorozu, please calm yourself. He will be fine.

Momo: how do you know!? We were out there risking our lives! And Y/N especially! We needed you!

All might looks down, clearly still feeling guilty about it.

Momo: I- I'm sorry sir... I shouldn't have said those things...

All might: no, you're right. I need to be there for all of you. I won't fail any of you ever again...

The rest of the class busts in with the injured hot topic fanatic in their arms.

Class: CAN WE GET SOME HELP HERE!?

Ejiro: will Y/N be alright?

Chiyo: yes he will, all of you go to your parents now.

They all comply and head off to their worried parents. Momo looks back at Y/N one more time and runs off. All might transforms into his normal form and coughs up blood.

Toshinori: I failed you kid... I failed you and your parents...

Chiyo: toshinori, quit it now! You didn't fail him! He will make it! Now, you go check on mr. midoriya!
