Hinako lives alone by the sea, quietly drifting through life after losing her family years ago. One day, a mermaid named Shiori saves her from a monster and says she’s come to eat her—just not yet. Until then, Shiori will stay by her side and keep her safe. In that moment, a deep hope swells in Hinako: Maybe this girl can finally grant her the ending she’s been waiting for.
