Opening the refrigerator after a bath, Inugami discovers a single plastic bottle of "ochimizu," a rejuvenating water Kokkuri-san purchased. Ignoring the written instructions not to drink it, Inugami gulps down the water in an instant, turning him into a child. Shigaraki, who also drank the water, appears from another room...
A little girl named Kohina ends up summoning a Kokkuri-san, a lower-ranking ghost in Japanese folklore. The Kokkuri-san she calls ends up being a white-haired handsome, young man. Although he had intended to merely haunt her at first, he becomes worried about her terrible eating habit of cup ramen for every meal, so he decides to haunt her in order to protect her.
