My Hero Academia: Hazmat Rising

Set four years before the original series, My Hero Academia: Hazmat Rising (の・ヒーロー・アカデミア・ハズマット・ライジング) follows a boy named Makage as he overcomes his past and trains to be a hero during his first year at U.A Highschool.

Plot
A sudden accident occurred on the east wing of the floating city known as I-Island, leaving over three hundred dead. Only one individual was left standing at the epicentre.

Years later, Makage is relentlessly bullied for his apparent quirklessness. However, he leaves everyone shocked when he manages to get into one of the most prestigious schools on the mainland and reveals that he might not be as powerless as he's been letting one.
