Kyouhei relocated to Tokyo to distance himself from past occurrences that he'd experienced in his old locale. While on a goukon with his comrades, he and his former neighbor, Shiba, stumble upon a lifeless and bloodstained corpse inside the lift after a night of inebriation. His sister, Utao, who owns a Kami-sama Doll, informs Kyouhei that Aki, an ex-pal, and his Doll are to blame for the vile act.
