Gas station employee Mayumi Takahashi confesses to novelist Kyouichi Yaguchi that she is a shinma. She acknowledges Miyu’s presence but believes the time for her return to darkness has not yet arrived. Upon returning home, Mayumi is confronted by Yaguchi’s wife, who insists he return to her. During a struggle where the wife attempts to strangle Mayumi, the shinma accidentally kills her. Yaguchi and Mayumi flee together by train, but Miyu tracks them down near the shore. Mayumi reveals her true name as Ayu and agrees to a match against Miyu in front of Yaguchi. Miyu defeats Ayu, sending her into the darkness. Grieving, Yaguchi transforms into a baby, and Miyu places him in a boat, sending him toward a village known as a land of happiness.
