OVA
Description
Naoto Yamanishi, a young police investigator driven by dedication and integrity, formed an intimate relationship with his professor and school nurse, Reika Kitami, during his school years. This relationship concluded with a sexual encounter that served as his first experience, leaving a lasting emotional impact. Kitami's subsequent departure devastated him, creating unresolved attachment that resurfaced later.
As an adult investigating supernatural cases with an older partner, Yamanishi probed two mysterious deaths at an academy—a female student found intact and a male teacher burned beyond recognition. During this inquiry, he encountered Toru Yuge, chief of the paranormal agency Tokken, who dismissed the police. While departing, Yamanishi witnessed a supernatural attack involving a robed girl and experienced a vision of Kitami, triggering deeper involvement in the occult.
After sustaining injuries including minor burns and a concussion, Yamanishi regained consciousness in a hospital. There, he intervened to rescue Tokken agent Aki Ichikawa from a demonically possessed vice-principal. He later filed a detailed report of these events, but his police chief dismissed it as nonsense. Yamanishi resigned from the force, surrendering his badge, gun, and handcuffs before seeking out Tokken at his former partner's suggestion.
At Tokken headquarters, Yuge granted him case file access. Researching these, Yamanishi discovered connections between Kitami’s past and current events. Kurumi Imari—a Tokken agent secretly possessed by Kitami—offered him drugged coffee, triggering physical and mental collapse. Under the drug's influence and Kitami’s manipulation, Yamanishi engaged in a ritualistic sexual encounter with Saki Kiriya, whom he mistook for Kitami. During this ritual, Kitami corrupted him by mixing his semen with her blood, inducing a demonic transformation that altered his physiology and psyche. This corruption manifested in extreme sexual aggression, including the violent rape of Kaori Saeki and an attempted assault on Aki Ichikawa.
Yamanishi’s corrupted state made him a pawn for both Kitami and her adversary, Jody Crowley. Crowley cursed him into servitude, compelling participation in a large-scale orgy in the academy basement. During the chaos, he assaulted Hiroko Takashiro and Saki Kiriya at Crowley’s command. He also restrained Yuge during Crowley’s ritual until Yuge disrupted the ceremony by shooting a black magic tome.
Following the ritual’s interruption, Yamanishi’s mind and body reverted to their original state. His demeanor normalized, and he was later seen purchasing snacks for Yuge and Takashiro in a non-antagonistic context, marking the end of his direct supernatural involvement.
Throughout his arc, Yamanishi exhibited gentleness and bravery when defending others. His corruption revealed a stark contrast: vicious, animalistic sexuality driven by external supernatural forces. His psychological vulnerability, rooted in his unresolved past with Kitami, rendered him susceptible to manipulation and dark influences.
