Kindred Spirits (Make The Best Villains)

Kirishima Eijirou is in the right place at the right time. He steps between Midoriya and Bakugou, saving the quirkless boy from gaining new burns. Izuku, impressed by the boy and his quirk, offers to help him train for UA's hero course after hearing that he wants to be a hero. Kirishima readily agrees and the two start meeting up nearly everyday before and after school. during their training sessions, Kirishima starts to notice Midoriya coming in with different types of injuries. One day, Midoriya shows up late and tells Kirishima something he will never forget. It's then that Kirishima decides he doesn't want to work with or for the people Midoriya was describing. They decide that they want to change things. So what's the next best attention-grabbing thing other than hero work?
Villainy.
