Eighth-grader Shigeo "Mob" Kageyama discovered his deep reserve of psychic ability at a young age. However, this power soon becomes a burden when he recognizes the potential danger inherent in his skills. Opting to suppress his abilities, Mob's only current application for his power is to impress his long-time crush, Tsubomi, who quickly tires of the same tricks. To gain control over his skills, Mob places himself under the guidance of Arataka Reigen, a con artist who claims to be a psychic and exploits Mob's powers for small change. Now, exorcising evil spirits on command has become part of Mob's daily, monotonous routine. Yet, the psychic energy he exerts is barely the tip of the iceberg; if his vast potential and unrestrained emotions run berserk, a cataclysmic event that would render him completely unrecognizable will be triggered. The progression toward Mob's explosion is rising, and attempting to stop it is futile.
