5th Division; Captain Aizen Sousuke

Captain of the Fifth Division. A rather unassuming individual, but one with great depth. Sousuke is a brilliant thinker and fighter--probably the second most powerful captain after Yamamoto--and is respected among shinigami for his chivalrous demeanor. He seems to be wary of Ichimaru Gin and his motives.

He acts gently toward his subordinates, particularly Hinamori Momo, his vice-captain. He recognizes the respect she has for him, and plays along with her hero-worshiping.

His zanpaku-to is the amazingly devious and powerful Kyouka Suigetsu.
