In a world where 80% of the population is born with special abilities known as Quirks (superpowers), the profession of Hero is no longer a dream but a legitimate career path. Izuku Midoriya, however, is part of the rare 20% born Quirkless. Despite this crushing reality and constant bullying from his peers, particularly his explosive childhood friend Katsuki Bakugo, Izuku retains his fervent dream of becoming a hero, inspired by the Symbol of Peace, All Might.*

Izuku's life changes forever when his sheer bravery, demonstrated by attempting to save Bakugo from a Villain despite his lack of power, catches All Might's eye. Recognizing Izuku's inherent heroic spirit, All Might reveals the truth of his own power, One For All, a Quirk that can be inherited. He chooses Izuku as his successor.*

The first season focuses on Izuku's grueling 10-month training regimen to prepare his body to inherit One For All, his acceptance into the prestigious U.A. High School—the top hero academy in Japan—and his initial struggles to control his devastating new power. The season culminates with the invasion of the U.A. campus by the League of Villains, led by Tomura Shigaraki, providing the newly formed Class 1-A with their first true test of heroism.
