The Telepathy Club is told that they are going to be shut down by the student council due to lack of members. It was then that one of the members, Inukawa, thought of possibly getting Mob to join. However, Mob gets a call from Reigen about taking care of an incident at Highso Girls' Academy...

Salt Middle School undergoes deep cleaning lead by the student council president, and one thug after another gets targeted. Meanwhile, the story about Mob defeating the shadow leader at Black Vinegar Middle School starts to get embellished and takes on a life of it's own, and Mob gets to be known as "White T Poison." All of the gang leaders from the other schools start to gather at Salt Middle School to confront White T Poison. Also, Ritsu awakens to his dormant psychic powers, and Dimple manages to convince Ritsu to pair with him to become stronger than his brother. Ritsu finally gets to experience those powers for himself.

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?
