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.

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.

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.

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...

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 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...

After splitting up with Mob, Reigen starts doing a lot of the jobs on his own. He then gets an offer to appear on a TV program. Reigen is ecstatic and accepts the offer, but this was all a trap set by Jodo Kirin, the president of the Rising Sun Spiritual Union. Jodo corners him during the live filming of the show and the fact that Reigen is a fraud comes to light. Reigen gets bashed from all sides and ends up having to hold a press conference...

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?

The boss of the Claw, Suzuki Toichiro barricades himself into Seasoning City Culture Tower after declaring war on the world. After instantly getting rid of the police barriers, they make their next move. Meanwhile, back at the hideout, Reigen and the others were making their move, as well. The former members of the 7th Division and the Awakening Lab head to the tower under Reigen's instruction. Sho and Ritsu also make their move to stop Suzuki's plans.

Sho finally arrived at Seasoning Cultural Tower and was greeted by Shimazaki, one of the Ultimate 5. Ritsu faces off with Shimazaki and urges Sho to go ahead. However, Shimazaki is able to teleport and he gets ahead of him. Meanwhile, Mob has woken up and is heading to the tower and is also approached by one of the Ultimate 5, Minegishi. Mob has a difficult time dealing with Minegishi, who controls plants, but then someone rather unexpected comes to his aid.

The Cultural Tower floats above Seasoning City. The final battle between Mob and Suzuki was about to begin. Mob is almost overwhelmed by the fact that he's able to completely release his powers, but then, he sees his younger brother, Ritsu. Mob regains his composure and he faces off with Suzuki, but Suzuki's power is too great. Mob finally gives up on trying to talk things out and puts everything he has into this battle. Who will be the victor?
