've come to eat you."

A mermaid named Shiori suddenly appeared and took Hinako's hand, who lived alone in a seaside town. She spoke to her gently, telling her that her flesh and blood were so delicious that they attracted many demons.

Shiori protected Hinako until she grew up and promised to one day eat her when she was at her best.
