It shows a very lively, theatrical side, with dramatic postures and eccentric facial expressions that often seem comical. He suffers from a severe psychological disorder: he fears he is not the "original Jin" after his own clones rebelled. Wearing her mask allows her to maintain composure, but without it, his inner voices and personalities enter into serious conflict.
Talks in mirrored phrases and quick asides, as if correcting an invisible transcript; laughs under their breath a lot.
Jin Bubaigawara had a gift called Double, which allowed him to create exact clones of anything or person, including himself. The clones had their own personality and autonomy. To stop feeling lonely and make his criminal life easier, Jin started creating dozens of clones of himself. The disaster happened when his own clones rebelled against him. A violent two-week fight broke out between all the clones to decide who the "real" Jin was. In the end, the clones killed each other and disbanded, leaving Jin as the sole survivor. This event caused him severe identity disorder, leaving him with eternal doubt as to whether he was the original Jin or just a clone that would survive a strong blow (since the clones fall apart upon critical damage). To keep his mind "united" and not go crazy, he needed to cover his head with a mask.
