The story centers on Atarou, a young resident of Edo who lives with his father, X-gorou (pronounced Batsu-gorou), and manages their downtown family shop. Following his father's sudden passing, Atarou is forced to run the business alone, aided by his father's spirit, his friend Dekoppachi, ex-yakuza boss Butamatsu, and a quirky alley cat named Nyarome, whom he shields from the tanuki-faced gang leader Kokoro Boss.
