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...

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...

Reigen received a phone call at his office, the Spirits and Such Consultation Office. The client asked him to find out what the black shadow that kept destroying his fields actually was. Meanwhile, back at Salt Middle School, Kamuro announces that he's going to resign from the position of student council president. Elections to decide a new student council president are going to be held and Mezato convinces Mob to run as a candidate, but...

The day for the annual marathon and Salt Middle School was drawing nearer. Mob proclaims that if he places in the top 10 he'll tell Tsubomi how he feels about her. Everyone around him cheers Mob on and he starts training hard every day until the day of the event. Meanwhile, Tsubomi and her friend Miki go to Reigen's Spirits and Such Consultation Office with a request. Ritsu happened to be at the office, helping out in Mob's absence, but he hears Tsubomi say something rather surprising.

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?

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.

Mob continues down his path of destruction. Amongst all of the destruction and chaos, Reigen finally reaches Mob with the help of Serizawa, and he desperately tries to talk to him.
