Peaceful days return after Mob's fight with Teru. As usual, Reigen continues to trick people as a fake psychic, and the president of the Telepathy Club, Tome Kurata, drags Mob around to find other espers. Then one day, a mysterious man talks to Mob's younger brother, Ritsu...

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.
