Unohana Retsu

She is a slender, youthful-looking woman with blue eyes and long, black hair tied into a large braid that falls down the front of her body. Despite her gentle and warm personality, she possesses a violent and bloodthirsty nature that she calls upon when she draws upon her past as the first Kenpachi. Unohana has a strong sense of duty and is well-respected as the best healer in Soul Society. She is soft-spoken, polite, and caring, using honorifics even when addressing her enemies, but is not to be taken lightly.
Captain of the 4th Division of Gotei 13.
