Mob Psycho 100

Kageyama Shigeo (a.k.a. Mob) is an 8th grader with powerful psychic abilities. Working under his not-so-capable master, Reigen, Mob uses his powers to exorcise evil spirits. But his will to be normal causes him to suppress his powers and feelings until he hits 100 percent--a point where his pent-up emotions are unleased and a darker power takes over.
