Sosuke Aizen| 𑣲ೀ⁺˖

He is a tall man with brown hair and eyes. He previously wore black glasses and a hairstyle with a part on the right side of his head, which gave him a friendly appearance.
Aizen radically changes his appearance, discarding his glasses and switching to a slicked-back hairstyle with a lock of hair that crosses his face almost down the middle.

His manner of speaking was slow and measured, and his face was always peacefully calm, as if everything happening around him had been planned in advance. This, however, was further evidence of his dangerous and manipulative nature, which was capable of projecting an image completely different from his true self.
