Eighth-grader Shigeo "Mob" Kageyama has tapped into his inner wellspring of psychic prowess at a young age. But the power quickly proves to be a liability when he realizes the potential danger in his skills. Choosing to suppress his power, Mob's only present use for his ability is to impress his longtime crush, Tsubomi, who soon grows bored of the same tricks. In order to effectuate control on his skills, Mob enlists himself under the wing of Arataka Reigen, a con artist claiming to be a psychic, who exploits Mob's powers for pocket change. Now, exorcising evil spirits on command has become a part of Mob's daily, monotonous life. However, 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. Kageyama Shigeo (a.k.a. "Mob") is a 8th grader with psychic abilities. He could bend spoons and lift objects with his mind from a young age, but he slowly began to withhold from using his abilities in public due to the negative attention he kept receiving. Now, the only thing he wants is to become friends with a girl in his class, Tsubomi. With his psychic "mentor" (who has no psychic powers), he continues his daily life, attempting to realize his purpose in life.
