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.

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.

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...

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

Mob continues to walk to the park where Tsubomi is waiting as he destroys everything around him, but the former upper echelon members from the Claw, Koyama, Sakuragi, and their boss, Suzuki stand in his way.

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.
