Setsuo Ito

Shigeo Kageyama, aka "Mob," is at first glance an average middle school boy who actually possesses powerful psychic abilities. Wanting to be normal, he suppresses his abilities, leading to a general emotional detachment. He exorcises spirits for self-proclaimed psychic Reigen, his master and a con artist. But when Mob's emotions reach 100 percent, his pent-up feelings unleash a dark and frightening power.

A summary episode of Mob Psycho 100 which features commentary from Reigen Arataka. (MyAnimeList)

Mob, Reigen, Dimple, and the newest member of the Spirits and Such Consultation Office staff, Serizawa, take a trip up to a secluded hot spring called Ibogami Hot Springs. Ritsu and Teru also join in on this trip. Reigen happened to get a request from the matron there to discover the truth behind the strange rumors going around there and save the inn. On their way there, Reigen and Serizawa start nodding off on the train and somehow get sucked into a parallel world. (Crunchyroll, edited)
