Retsu Unohana

Retsu Unohana (卯ノ花 烈, Unohana Retsu) is the captain of the Fourth Division in the Gotei 13. She is one of the oldest and most experienced captains, and is the Soul Society's best healer. Her lieutenant is Isane Kotetsu.
Unohana has the appearance of a very youthful woman with blue eyes and black hair. She wears the standard Shinigami captain uniform apart from using an obi instead of the normal sash. Her hair is long and is always worn as a large braid in front. Over 100 years ago, she did not have the large braid.
Unlike most Shinigami who carries their Zanpakutō in their sash, Unohana has a large string attached to the sheath of her Zanpakutō and carries it over her shoulder, or has her lieutenant Isane Kotetsu carry it for her, whenever they are together on the battlefield.
