Rai Mamezuku is a reclusive plant appraiser secretly employed by the Higashikata Fruit Company. Rai is an eccentric, blunt, quick-witted, and analytical man who often comes across as cold-hearted. He is extremely antisocial, going to great lengths in order to stay isolated. His stand, Doggy Style, allows him to unravel his body into band-like cords.
