Reigen and Mob receive a new job. This time, their client is a wealthy man named Asagiri Masashi. He's not just rich, but super rich, so Reigen and Mob head to his mansion only to find other self-proclaimed psychics there as well. One of the psychics there happens to include the president of the Rising Sun Spiritual Union, Jodo Kirin. The job is apparently to exorcise the evil spirit that is apparently possessing his daughter, Minori.

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.

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.

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.

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

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.
