From the creator of One-Punch Man!

Teru journeys deep into the branches of the Divine Tree in search of the force attempting to control Seasoning City, only to be overcome by a strange mannequin of Mob.

Meanwhile back in town, the real Mob gradually realizes that no one, not even his master Reigen, may prove immune to the brainwashing of Psychohelmetism--so it's up to Mob personally to confront the dummy of himself inside the Divine Tree... and the all-too-familiar spirit pulling its strings!
