The story tells of a little girl named Kohina who, one day, accidentally summoned Kokkuris-san, a low‑ranking spirit from Japanese folklore. Kokkuris-san is a young, incredibly beautiful spirit with long silver hair. At first he simply intends to perform his "official duties"—as befits a ghost—to stalk and scare the girl. However, moved by affection for her, he watches over her with concern, paying attention to her dreadful food preferences of having a bowl of ramen at every meal. And Kokkuris-san stays with Kohina, now to look after his little charge.
