3 weeks earlier

Izuku has been resting since he came in first place at the sports festival, but he couldn't shake the feeling that something bad was going to happen. And it was coming soon.

News: We have reports that the number one villian All for One has broken out of Tartarus. We don't have any explanation on how, but pro heroes are on the site fighting

Izuku: Oh My——

3 weeks later

News: It's all over the news All Might is fighting All for One again but his powers have grown weaker. This may be a tragedy in the works folks, w-we may lose our Symbol of Peace

Izuku thoughts: H-hold on dad I'm coming

(In this story All for One is Izuku's real father who left him at the age of 1, but his mom married All Might to fill that gap in Izuku's life)

All Might: I-I can't hold on much longer. Yang, Akari, Izuku, and Inko I-I love you

All for One prepares and delivers his final blow to All Might and a massive cloud of dust appears in their place

People who saw the scene were sobbing at the loss of their Symbol of Peace, the hero that brought light to them

News: W-wait there's a kid, KID STOP YOU'LL DIE. Oh MY GO—

The smoke clears to see a dead All for One but a living All Might holding his only son's lifeless corpse

All Might: M-my Son!!!! Izuku Nooooooo!!!

Everyone who had a crush on Izuku saw this scene were in tears, sobbing at the fact that their love of their life was now dead

Another 3 weeks later brought to you by chibi All Might crying

All Might comes through the door singing a happy tune

All Might: Well Hello students I have some news

The class in a depressed tone: Yes

All Might: You can come in now

Izuku enters the room outside of his armor with his shirt unbuttoned to reveal abs and a massive scar over his chest

Izuku: Hey guys

Class: Deku/Midori/Midoriya Don't ever do that again you worried us. Not to be rude but how are you alive?

Izuku: RG was able to heal most of the damage and she brought me back

All Might: Well anyways students we have a new teacher today. Introducing Cullen240.

Cullen: Hello everyone you may know me as the pro hero Cullen 240 but you can call me Angie sensei
