Season 1

The ringing of the phone echoes through a high-rise building late at night. The voice on the other end introduces herself as Mary-san.

Hiding her psychic ability, Shizuka hopes to enjoy school life as an ordinary student. However, her peace is shattered through her friend, Inagawa, who brings in a Kokkuri-san sheet. A spirit appears in response to Inagawa and the others' summons, and its evil grasp closes in on Shizuka. Can Kamui fulfill Shizuka's request to perform an exorcism 'secretly, without anyone seeing'?

Will Kamui be able to rescue Shizuka who's trapped in a narrow gap of a building where she is out of reach?

With Yui's life and the top spot of playmate on the line, the battle between Oichi and the black cat begins!

Shizuka, who has gone for a drive with Kamui, picks up a soaking-wet woman along the mountain pass at night. Eerie handprints appear on the fogged-up windows, and the sound of the car creaking begins to echo from outside. A night of terror begins! Showing off her youth in a tight bikini as she sits in the driver's seat, Shizuka is pursued by the Jet Hag Gang—the mountain pass's supernatural menace! Oichi's driving skills and Kamui's techniques explode onto the nighttime mountain pass!

The ghostly phenomenon of the girl Hanako-san is haunting elementary schools all over Japan. Kamui and Shizuka join forces to exorcise them all at once. As their friends are exorcised one after another, the Hanako-san from all over Japan panic, and they gather at an abandoned school deep in the mountains. What is the desperate plan they have devised to turn the tide?!

A voluptuous mother and her cute daughter visit the office from abroad. When the mother asks Kamui to exorcise the succubus possessing her, Kamui suddenly rips her clothes off! He kicks a flustered Shizuka out of the room and begins the exorcism. Will Shizuka merely stand by and watch Kamui's battle, which could potentially become an international incident?

After being ambushed by a succubus and having his life force completely drained, Kamui naturally (?) falls into Hell.

After sucking out Kamui's life force, Lily somehow loses the ability to attack humans. While feeling worried as her power wanes day by day, she spends her days enjoying the lively company of Shizuka and the others. One such day, Lily decides to keep a vigil to protect Shizuka, who has been possessed by a nightmare. Meanwhile, Kamui, the one she needs most, is away from the office on other business. The curtain rises on a night spent alone between Lily, starving for spiritual energy, and Shizuka, the perfect prey for the supernaturals.

After spending the night with her friend Lily, Shizuka wakes up to find that Lily had vanished from the office. Filled with unease, Shizuka heads to school, only to discover that Lily had been erased from the memories of both teachers and students. In search of proof that Lily had ever existed, Shizuka rushes out of school. Meanwhile, Kamui gazes at the morning sun, recalling last night's battle. What was the outcome of the fight with Lily, in which they staked their very existence, their pride, and the things they could never compromise on?!
