"Hero society is a web of lies. My role? To tear it apart from the inside." In the dark underworld of villainy, everyone fears Genesis, one of the most destructive weapons of the League of Villains. Cold, calculating, and armed with a Quirk capable of rewriting reality itself, Y/N is Tomura Shigaraki’s ultimate trump card. Her new mission: infiltrate U.A. High School as a new transfer student in the prestigious Class 1-A. The goal is simple—gather intel, analyze the future heroes' weaknesses, and pave the way for All Might's downfall from the inside out. Playing the perfect little hero should have been child's play. But she didn't count on Katsuki Bakugo. Explosive, dangerously perceptive, and painfully stubborn, he is the only one to notice that Y/N's reflexes are far too lethal for a regular student. A thrilling and electric game of cat-and-mouse begins between them. But the longer she plays the hero, the closer Y/N gets to burning her own wings. What happens when the League's monster starts to care for the very people she was sent to destroy... and most of all, for the angriest boy in the class?
