Kenshin, often referred to as Master Kenshin, is a prominent character in the 2022 film. He is a professional psychic and fortune teller who becomes a central figure in the story's exploration of the cursed videotape phenomenon.

His background is rooted in a childhood spent working at a shrine alongside his father, who performed exorcisms for money. It was during this time that Kenshin's father came into possession of the infamous cursed videotape, brought to them by victims seeking to be freed from its spell. This early exposure to the supernatural, combined with a growing disillusionment with his father's mercenary work, shaped his future outlook.

Personality-wise, Kenshin presents himself as a calm, credible, and knowledgeable authority on the occult. However, this exterior masks a more cynical and manipulative nature. He is not driven by a desire to help others but rather by a twisted sense of purpose and entertainment. He is intelligent and calculating, using his position to orchestrate events for his own amusement and gain.

Kenshin's primary motivation is a profound belief that his destiny is to fulfill the human desire for excitement. He becomes disillusioned with the idea of simply containing or destroying the supernatural, instead viewing the curse as a form of spectacle. He deliberately spreads the videotape, seeing it as his own brand of entertainment and a way to generate viewership and attention for himself.

In the story, Kenshin serves as an antagonist. He is first seen introducing the protagonist, the prodigy Ayaka Ichijo, to the legend of a new, more deadly variant of the cursed videotape on a televised variety show. Throughout the film, he pretends to assist Ayaka and others in their research, performing an exorcism ritual on the tape, but his actions are ultimately self-serving. His role is to be the initial catalyst for the plot and the hidden source of the curse's modern spread.

Key relationships define his arc. His primary connection is to Ayaka, whom he challenges to investigate the mystery, though he secretly uses her intellect for his own ends. He also has a significant, though absent, relationship with his unnamed father. His actions are a direct reaction against his father's profession of performing exorcisms, which he saw as a mockery of the supernatural. His cynical motivation is to spread the curse as authentic terror, in contrast to what he perceived as his father's fake cures.

Kenshin undergoes a notable development, or rather a revelation of his true nature. Initially appearing as a helpful expert, he is ultimately revealed to be the individual responsible for distributing the cursed tape on the darknet. His master plan is exposed during a confrontation with Ayaka, where he explains his philosophy. This climax leads to his immediate comeuppance, as he falls victim to the very curse he was exploiting, dying on the spot as his own schemes collapse.

His notable abilities are primarily as a medium and exorcist. He claims the power to perform rituals that can counter or remove the curse, and he demonstrates a performance of such an exorcism on the videotape. However, his defining "ability" is not supernatural but psychological: his skill in manipulation, showmanship, and using his reputation as a psychic to create a grand, horrifying spectacle for a modern audience.
