TSUYOSHI: Daremo Katenai, Aitsu ni wa

Tsuyoshi Kawabata works at a convenience store in a city west of Tokyo and is also the world's most powerful fighter, though he has no interest in combat. His reputation draws martial artists from around the globe, all of whom come to challenge him and are consistently defeated in private, often ending up injured in the store's parking lot. To keep these encounters as unobtrusive as possible, he enforces three conditions: each fight is a single, one-time event, takes place in a secluded location, and must remain a secret, regardless of the outcome.
