The Good Citizen

An AU where Izuku is just an ordinary boy. He never meets All Might and has his application for Yuuei's entrance exam rejected because of his quirkless status. He still wants to be a hero, but then again, he's just a normal kid with a mom who works two jobs, and since he failed to get into his dream school, he still has to get into another one, he doesn't have time. to go to the gym or learn to fight, or whatever. And yet, he wants to be a hero, so he grabs a pair of old skates and a stick. And he sneaks out the window at night, intending to be a vigilante.

But like a normal boy, he's a bit of a coward, so when he encounters his first crime, instead of getting involved, he calls the police. He calls the police and hides and is delighted when a police car arrives a few minutes later and does its job. And then he repeats that, goes out, finds a crime and calls the police. And repeat. And the next time, he identifies himself as "Good Citizen" when the person on the line recognizes his voice. And the name sticks. And Izuku keeps it, thinking of it as a way to keep his identity safe. But one day, 'The Good Citizen' calls the police on a group of men beating up a guy. And next he stops a man from harassing a girl.

The mens who beat the guy are part of a powerfull gang and their high-rankers discovers that the person who reported them was the same person who has been making several reports. The old man who harassed the girl was an important member of the HPSC, whose arrest creates a huge scandal

With this he successfully angers the villains and the HPSC all at once. Next week there's a bounty on 'snitch's head. And an arrest warrant for the vigilante who is 'an enemy in the making for the society of heroes'.

Then a race begins, villains and heroes mobilizing to kill/arrest one (1) well-intentioned green bean.

And, out of nowhere, this all becomes Aizawa Fucking Shota's problem.
