Yuta and Mana come upon a boy who has just escaped a kidnapper. The boy, Nanao, is hurt, but he takes medicine that heals his wounds instantly. He says his mother has been giving him this medicine for some years now.

The couple take Nanao back to his home, much to his mother's gratitude. But his grandmother warns them to take him away from the house, and shows them a picture of who she says is Nanao's mother -- a woman with a completely different face. Rumors say that a fight in that home 25 years ago by a divorced couple over their only son left the mother with a horrible scar on her face. Are Nanao and his mother connected with that bloody incident? And why is she feeding him doses of mermaid's flesh?
