Originally created by ONE, the webcomic artist best known for creating One-Punch Man, for Ura Sunday magazine in 2012, Mob Psycho 100 tells the story of Shigeo "Mob" Kageyama, an 8th grader with psychic abilities. He tries his best to not stand out, but his powers often rope him into increasingly dangerous situations as the years pass, so he buckles down his emotions to keep a lid on them.
As more threats continue to pursue Kageyama, the boy learns how difficult it is to keep his emotions in check, but the fate of the world depends on him doing so. His hilarious mentor, Reigen, often makes things worse given that he has his own goals and wants for Mob. The first season of the anime aired in 2016.
