A self-proclaimed exorcist named Arataka Reigen attempts to exorcise an evil spirit, despite only stumbling onto it by accident. The spirit seems annoyed at his attack, which consists of throwing a handful of table salt which actually meant to be purified salt, much to Reigen's shock. Reigen then unleashes his secret weapon: calling in the actual psychic Shigeo Kageyama (a.k.a. "Mob") to banish the spirit for him with his psychokinesis powers.
