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.

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.

Three years ago, Serizawa was troubled with about his psychic powers. One day, he was visited by the boss, Suzuki Toichiro. Serizawa ends up trusting him since he's the first person to understand what he's going through. But Mob then brings up the fact that Serizawa is being used and tells him, "I'll be your friend." Hearing Mob say that, Serizawa... Meanwhile, after defeating Sho, the boss starts gathering up the energy he was sharing with his followers and turns into an energy monster.

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?
