In a realm teeming with Quirk‑possessing superhumans, college student Kouichi Haimawari yearns to become a hero he idolizes. Unfortunately, his only power—a sliding motion that propels him at roughly bicycle speed—limits what he can achieve. Consequently, he turns to low‑risk, extra‑legal gigs, tackling local jobs beyond police reach and licensed heroes" jurisdiction.
One day he crosses paths with two oddballs: a fiery street fighter known as Knuckleduster and the viral idol Pop☆Step. Their encounter presents Kouichi with the chance he has always chased. A perilous new Quirk‑boosting drug is turning ordinary citizens into instant criminals, and Kouichi joins the pair to halt its spread. As the trio digs deeper, their chaotic alliance works to neutralize offenders ignored by law enforcement.
His modest reputation as a "slip‑shifter" keeps him in the shadows, yet he is determined to protect his town. The drug"s rapid onset turns citizens into violent threats overnight, sparking a silent crisis that the authorities cannot address for everyone today.
