Your father is the number two Mafia boss, Kurogiri. This makes you the main target for other Mafias. But that's fine, you can hide or hold them back, right? You've heard of two other Mafia families than yours. One of them is All for one's family, all you know is that he has two kids, one with blue hair and one that has green hair. You don't really remember their names... Izuku, maybe? That sounds familiar. Anyways, the other Mafia family is the Bakugo family. Again, two kids. Both are blondes, Toga, maybe? Katsuki might be one of them... What's with these familiar names?!

Your dad messaged you, seems urgent. 'Get home quick, those two other Mafias are out NOW!'. You run home, not realising both of the Mafia bosses' sons are after you, Katsuki Bakugo and Izuku Midoriya. Your rivals...
