Psychics fight with supernatural phenomena that cannot be explained by science. Arataka Reigen 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 Shigeo Kageyama, 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%.

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, Tome Kurata, drags Mob around to find other espers. Then one day, a mysterious man talks to Mob's younger brother, Ritsu...

Salt Middle School undergoes deep cleaning lead by the student council president, and one thug after another gets targeted. Meanwhile, the story about Mob defeating the shadow leader at Black Vinegar Middle School starts to get embellished and takes on a life of it's own, and Mob gets to be known as "White T Poison." All of the gang leaders from the other schools start to gather at Salt Middle School to confront White T Poison. Also, Ritsu awakens to his dormant psychic powers, and Dimple manages to convince Ritsu to pair with him to become stronger than his brother. Ritsu finally gets to experience those powers for himself.

Kurata Tome has always dreamed about communicating with the universe through telepathy, and now, her high school graduation was drawing nearer. When they are about to start winter break, she tells the Telepathy Club that she is going to disband them.

After the incident with the religious organization (LOL), the evil spirit, Dimple, keeps following Mob around. Also, because of the incident, Mezato Ichi from the school paper starts following around Mob, as well. Then one day, another student joins the Body Improvement Club. Progress Towards Mob's Explosion: 45%

Ritsu and the others get abducted by a mysterious man named Koyama, and get taken to the secret organization Claw's 7th Division. Claw is an organization who is trying to lead the world to a better future by taking it over. One of Claw's assassins, Terada goes after Mob and Teru, but they overpower him and get him to tell them secrets about the organization. In order to save Ritsu, Mob heads to the 7th Division but encounters another member of Claw.

The group somehow finally makes it to the summit of Mt. Mudboat. Takenaka had been up all night reading all the texts about UFOs and the Telepathy Club comes together to send a telepathic message into space, but there is no UFO in sight.

Mob and Teru infiltrate the Claw's 7th Division to save Ritsu. Meanwhile, Ritsu tries to escape with the other esper kids and they run into the upper echelon and leader of the 7th Division. Teru and Dimple run into trouble after a strenuous battle, and the boss from Claw finally shows himself...

Because of the lack of clients visiting or calling his office, Reigen decides to take his business on the road. They go to Cuticle City where there seems to be various urban legend sightings. They immediately get a request to deal with something called the Dragger. With the help of a local psychic they happened to meet named Shinra Banshomaru they go to take care of the Dragger as well as the other urban legends that plague the city.

Mob is challenged to a one-on-one fight with Black Vinegar Middle School's shadow leader, Teruki Hanazawa, 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...

After defeating all of the gang leaders from the surrounding schools, Ritsu feels omnipotent. And then, he's confronted by none other than his older brother, Mob. Mob knew that Ritsu had wanted psychic powers for a while, so he congratulates him. However Ritsu doesn't greet his brother with kindness. Meanwhile, a mysterious man watches the brothers from a distance. He easily manages to grab Ritsu, and tries to drag him off. Mob activates his powers in order to save his brother.

Reigen sets up an official homepage for his Spirits and Such Consultation Office and he immediately starts to get jobs left and right, including a middle-aged man asking Reigen to curse someone and a woman who's being haunted by a ghost. As he was listening to their problems, Mob realizes something. Why do people treat humans and spirits so differently? Meanwhile, Reigen gets another request from a group of college students that want to take a photo at a haunted location, but...

Mob is very busy preparing for the cultural fair that's coming up in two weeks. Meanwhile, Serizawa is trying to start over, and is thinking about going to night school.

Mob is finally pushed to his limit when he has to face Sakurai, Muraki, Matsuo and Ishiguro of the upper echelon. But then, he comes to a rather surprising decision...

A giant broccoli known as the Divine Tree grows in the middle of the city and looks down upon Seasoning City. It's time to fill out surveys about career paths at Salt Middle School and the students are filled with various feelings. While they all talk about their hopes and dreams, Mob can't seem to think of anything himself.

After Psycho Helmet's appearance, tree roots start emerging all around the city. Sensing danger, Mob goes with Reigen and Ritsu to destroy the Divine Tree, but eventually, they are overwhelmed by the members of the Psycho Helmet Religion.

After winter break is over, Mob is hit with shocking news. Tsubomi is actually going to transfer within the next month.

After hanging out with the Body Improvement Club and Telepathy Club more, Mob starts to feel joy like he'd never felt before. One day while he's having fun with them, he gets a call from Reigen, spoiling his fun. Mob asks Reigen to stop summoning him so suddenly, and Reigen just handles the situation in his usual overbearing manner. And because of something very minor, a gap forms between them. Reigen is forced to go on jobs without Mob, forcing him to reexamine himself.

With his house up in flames, Mob and Dimple find something that resembles his family burnt within the fire. They immediately go to find who's behind this and run into members of the mysterious group, the Claw. Unable to control his rage, Mob disposes of them immediately, but then Koyama and Sakurai from the 7th Division appear before him. They end up meeting up with Teru and Reigen, who were also attacked by members of the Claw, at a secret lair. What could the Claw be plotting?

Mob is in a great mood because he got to talk to Tsubomi for the first time in a while. As he's walking through town, he feels the stares of other girls...

Mob, Ritsu, and Teru are trapped in a room where they can't use their powers. And then, someone rather unexpected shows up in front of them: Mob's master and self-proclaimed psychic, Reigen. Somehow, Reigen is mistakenly thought as the boss of Claw, and easily manages to get inside and successfully saves Mob and the others. However, there is no way that Ishiguro would let them get away with this. As they try to escape the 7th Division, the upper echelon stands in their way.

Mob heads into the Divine Tree, only to have to face off with Teru. Mob finds himself speechless, having to confront even Teru who has been completely brainwashed by Psycho Helmet.

Mob tries to save a child that is about to be run over by a car and is run over himself. People start to gather but Mob stays silent.
