Haruka “Yankee” Tachibana thought being sent to his grandma’s village for the summer would be a boring punishment. Instead, he’s tossed into the lair of Kaito — the “Mura no Kishuu” (Village’s Demon Brat) — a wild, untamed boy rumored to have a demon sealed inside him. When Kaito’s seal starts breaking, the village elders declare an absurd solution: “Tame the demon through combat with a pure-hearted yankee.” Too bad Haruka’s heart is 90% pompadour and 10% misplaced pride. Now they’re stuck together, brawling daily, accidentally saving the village, and maybe — just maybe — learning that “yankee” and “kishuu” are two sides of the same lonely coin.

At its core, the story plays with the . Is the Yankee in control because of their physical dominance, or is the village in control because they dictate the rules of the encounter?

When a small rural village’s most feared yankee (delinquent) gets roped into a bizarre local “purification ritual” with the demon-possessed troublemaker of the shrine family, the only way to break the curse is to… fight, banter, and somehow coexist. Violence has never been this domestic.
