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 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...

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.
