Ushiro no Shoumen Kamui-san

Shizuka is an ordinary high school student with an unusual problem: she doesn't just see ghosts—they are drawn to her like moths to a flame. Their presence is part of her everyday life: whispers in empty corridors, shadows behind mirrors, cold fingers on her shoulder after class. No one believes her.

To keep from going crazy and becoming a local legend, Shizuka takes a job as an assistant to Kamui, a famous but eccentric exorcist whose methods of exorcism leave everyone asking the same question: "Is this for real?”

Kamui is a genius with sensory abilities. His intuition is like a precise compass in the world of spirits. But instead of spells, holy water, or ancient rituals... he uses cakes. And songs. And, in extreme cases, he stages real dance battles with ghosts.
