Shoji's sweet-natured girlfriend. She works at the same restaurant as Shoji. Early on in the manga, Hachi once dreamt of Shoji two-timing her with a buxom, Prada-loving city girl named Sachiko (she thought of the name randomly). Ominously, it later turned out to be true, though the real Sachiko is nothing like "virtual" Sachiko.
