Kunitoshi Joukyuu has settled into a quiet life teaching martial arts in Japan since the events of Aiki, with Veronica and Kageyasu still close by, until a karate-master chef makes him an offer he can't resist: travel to America, take down the local gangs, and eat like a king in exchange. Joukyuu jumps at the excuse to leave his sleepy routine behind, dragging Veronica, Kageyasu, and the fighter Bull along for a trip that turns into one long string of brawls. This direct sequel to Aiki trades the original's tournament structure for episodic chaos on foreign turf.
