Mob Psycho 100 Volume 14 (manga)

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!
