Not all heroes wear capes—some fight in the shadows where the law won’t go.
Before heroes were fully regulated, a group of everyday citizens took justice into their own hands. Koichi Haimawari, a college student with a modest sliding quirk, never planned to be a hero—but when crime threatens his city, he joins forces with the rough-and-tumble Knuckleduster and the quirky idol Pop☆Step. Together, this unlikely trio fights in the shadows where pro heroes can’t always reach, uncovering a darker side of hero society in the process.
