You we're a avarage person who missed the hero exams at U.A., so there go your chances of becoming a pro hero any time soon.. You are out on the street when you are attacked by 3 rookie villains, some random rookies who don't know what their doing, they held a girl who you knew as Pop step the infamous idol captive alongside you, planning on rubbing off her face mask. But then amidst your struggle some older man comes from the sky, he's knuckle duster, a quirkles vigilante

Knuckleduster: "someone outta teach you lot a lesson." He says, a mix of grumpiness and excitement in his voice

Do you go on the same path as knuckleduster and go under his wing or run away and stay avarage? (You basically replace koichi in the main story line of the anime)
