Episode 1

"Self-Proclaimed Psychic: Reigen Arataka ~And Mob~" is the first episode of the Mob Psycho 100 anime adaptation.

Synopsis
Psychics fight using supernatural phenomena that cannot be explained by science. Arataka Reigen, who runs the Spirits and Such Consultation office, is one of those psychics... well, a fake one. His only hope is a super dull middle-schooler named Shigeo Kageyama, a.k.a. Mob. 27% towards Mob's explosion.

Summary
Arataka accepts Hanako's request to exorcise a spirit, showing her the prices and explaining that it's hard to remove a spirit entirely. Her boyfriend Taro suspects Arataka is a fraud and doesn't believe he is a real psychic. Reaching Hanako's place, a spirit shows up, shocking everyone, and Arataka tries to use salt on him, but it has no effect as it is ordinary store-bought salt. Arataka then decides to call his secret weapon, his student Mob, who comes in and defeats the spirit with ease. Later Arataka pays Mob, who wonders why Arataka called him for such weak spirits, but Arataka tries to explain he is too powerful and would melt everything.

Mob eats dinner with his family, where he bends a spoon unconsciously, and his mother tells him that if he keeps bending them, they will replace them with his allowance. The next day, Mob goes to school, where he sees Tsubomi, the girl he likes. He does badly in his math and physics classes, and after school, Arataka calls him to the station for a big job.

They head out to Honeido Tunnel, located along the old highway. The tunnel has been closed, but people keep disappearing. Thirty years ago, a biker gang died, and Arataka believes the hatred from those people may be swirling around the tunnel. Arriving at the tunnel and entering, Arataka quickly runs back, asking Mob why didn't he enter. Still, Mob explains that he felt Arataka had everything under control and that the place felt scary, as he felt something from the tunnel. Entering, Mob comments that he feels the presence of spirits and that they are surrounded, and Arataka tells him to deal with the weak ones. Arataka then runs into a big spirit, mistaking him for a wrestler, but it is the Boss of the Biker Gang. He explains that he slipped on a banana peel and crashed, resulting in his whole gang crashing and dying. He attacks Arataka, but Mob protects him. Arataka hits him with salt in his fist, but Boss doesn't feel anything. Mob then starts melting Boss, who asks them to stop, saying they were forced to attack people. Mob leaves him in a degraded state, and Boss explains that there is a hundred of years old spirit down the tunnel responsible for all the deaths. Arataka doesn't believe him, but Mob feels that the creepy aura has not disappeared and decides to go and check. He faces a more prominent and vital spirit, who eats him, but using his psychic powers; Mob melts him from the inside. Mob returns to Arataka and Boss, commenting that the spirit wasn't that powerful. He gives a photo of Boss's gang to Boss, making him cry and allowing him to pass on peacefully. Heading home, Mob asks Arataka why he didn't do anything in the tunnel and Arataka, shocked, explains that he told him he was leaving the weak spirits to him.
