Season 1

Psychics fight with supernatural phenomena that cannot be explained by science. Reigen Arataka that 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 Kageyama Shigeo, a.k.a. Mob. 27% towards Mob's explosion.

The Telepathy Club is told that they are going to be shut down by the student council due to lack of members. It was then that one of the members, Inukawa, thought of possibly getting Mob to join. However, Mob gets a call from Reigen about taking care of an incident at Highso Girls' Academy...

It's great that Mob joined the Body Improvement Club, but he suddenly faints as he's running along the riverside. His wish is to get stronger and to be able to get closer to his beloved Tsubomi-chan. One day, as Mob is feeling troubled, a woman with a strange mask approaches him... Progress toward Mob's explosion: 20%

Mob is challenged to a one-on-one fight with Black Vinegar Middle School's shadow leader, Hanazawa Teruki, otherwise known as Teru. Mob doesn't use his powers but Teru goes all out on him, destroying everything around him. Teru continues to unleash his incredible power when Mob suddenly remembers a tragedy that happened between him and Ritsu...

Peaceful days return after Mob's fight with Teru. As usual, Reigen continues to trick people as a fake psychic, and the president of the Telepathy Club, Kurata Tome, drags Mob around to find other espers. Then one day, a mysterious man talks to Mob's younger brother, Ritsu...
