In the suburbs of Tokyo, a group of six girls have played together at the park since they were little, but eventually have to switch schools. Before they leave, they plan to make a time capsule, but are unable to do so. The story follows the girls four years later as they meet again.
Koichi Haimawari is a dull college student who aspires to be a hero but has given up on his dream. Although 80% of the world’s population has superhuman powers called Quirks, few are chosen to become heroes and protect people. Everything changes for Koichi when he and Pop☆Step are saved by the vigilante Knuckleduster and get recruited to become vigilantes themselves!
