Keiji Mogami was once known as "The Greatest Psychic of This Century," but after passing away, he became an evil spirit with a twisted sense of morality. Driven by bitterness towards humanity's greed and selfishness, Mogami lost his moral compass and sought to use his powers for personal gain. He believed that possessing people who gathered grudges would help him achieve his goals. To this end, he was willing to destroy a girl's body and impale her father in order to fulfill his desires.
