Retsu Unohana Zanpakuto
Minazuki (Purify the Flesh)


Retsu Unohana 4th Division Captain a soft-spoken lady who never displays distress even in the most perilous situations; she responds with sharp-minded thinking. . As the captain of the 4th Division, Unohana is commonly healing and treating the most severe injuries and performing major surgeries, normally on the captains and if necessary vice captains.


(Purify the Flesh) When in its sealed form it resembles a curved tachi. In its shikai, the entire sword transforms into a gigantic, flying, one-eyed creature resembling a manta ray. It has the ability to heal people by swallowing them. When Unohana reseals Minazuki, it dissolves into green mist and reforms into the sheath of her zanpakuto. Minazuki appears as freed zanpakuto in the Zanpakuto Unknown Tales anime arc, as a mute figure in a hooded robe, pretending he/she was imprisoning Yamamoto. She along with Shunsui and Ukitake are among the oldest and strongest in soul society.

In sealed form, Minazuki is slightly longer than an ordinary katana, and resembles a nodachi The tsuba has an oval shape and the handle is red. Instead of tying it to her obi, Unohana carries her Zanpakutō over her shoulder by a rope strap or lets Isane carry it for her. 

Its release command is unknown. When released in Shikai form, Minazuki will start to morph, turning into a green like gas substance before taking a solid shape of a giant, green, one eyed Manta Ray like creature with the capability to fly. Minazuki can act as transportation and will change back into the green gas substance before returning to its sword form when its duty has been fulfilled.

Shikai Special Ability: It is large enough to transport many people on its back (at least a dozen, based on its size when compared to those riding it). It seems to act on verbal orders and when landing it has the ability to somehow create a pair of bird like legs. Minazuki's main aspect is its ability to heal. When the wounded are placed within Minazuki's mouth, they are swallowed and stored inside it's stomach. Minazuki's stomach acids are strong healing medicines and ointments which gradually soak over the wounded, curing their injuries. Currently it has shown to be able to carry at least five people within it's stomach. When Unohana gives the word, Minazuki will regurgitate the people back out of its mouth.
