Captain of the 4th Division :The Sweet and Nurturing...Retsu Unohana

Sweet, nurturing, caring, thoughtful, considerate, and fearful, these are the traits that define 4th Division's captain, Retsu Unohana. Just like Jushiro Ukitake and Shunsui Kyoraku, she was originally the captain of her division since the beginning. Not much is known about her except that her Zanpaktou is called Minazuki (Purify the Flesh), but her release command is unknown. Being captain of the 4th division, she is fond of treating the sickly and injured and is Soul Society's greatest healer. Other divisions call the 4th Division weak, spineless, and unfit for combat, but ironically, other squads are afraid of Retsu Unohana for her intimidating nature, despite the fact that she's speaking normally with a gentle and sweet voice. She was the one that told Ichigo that he was unaffected by Aizen's Zanpaktou and he is the only one that stands a chance to defeat him. Unohana also treated to her former captains (Shinji, Love, Rose, Kensei, etc). Hopefully, Unohana will fight back and possibly show what her true powers are other than healing the sick.
