Sosuke Aizen

He is the captain of the Fifth Division of the Gotei 13.

Aizen is a tall man with brown hair and eyes. He wears black glasses and a hairstyle with a part on the right side of his head, which gave him a friendly appearance.

He wears the typical Shinigami outfit, except for his captain's haori, which shows his participation in the gotei 13, as captain of the 5th division.

Aizen is surprisingly kind and courteous to all his interlocutors, allies, even enemies. His way of speaking is slow and deliberate, and his face usually always shows a peaceful calm, as if everything that happens around him had been planned in advance.

In Soul Society, everyone considers Aizen to be one of the most pleasant and respected captains, as well as loved and admired by all Shinigami, especially his most direct subordinates.

This, however, was another example of his dangerous and manipulative nature, which was capable of projecting a completely different image than the one he really has. The real Aizen cares little about those who serve him

Aizen lacks any type of honor and compassion, not hesitating for a single moment to use and even kill as many people as necessary to achieve his goals.
