Minazuki

Sheathed, Minazuki runs a touch longer than a standard katana and takes after a nodachi, fitted with an oval guard and a red grip. Rather than binding it at her sash, Unohana slings the sword over one shoulder on a rope strap in tachi fashion, or hands it off to Isane to carry for her.

Its release phrase and the way it transforms are never shown. In Shikai the blade becomes an enormous green, single-eyed creature resembling a manta ray, able to fly and to sprout legs for landing, and it can shrink down to about the size of a puppy. Its healing gift works by swallowing the injured into its belly, where potent medicinal fluids seep over their wounds; it holds at least six people at once and spits them back out at Unohana's command.

The Bankai, whose name renders as All Things' End, has Unohana run a hand along the edge until the steel dissolves into a thick, dark-red fluid like blood, which pours down to blanket the battlefield before the blade re-solidifies with the liquid still streaming off it. She can hurl slashing waves of the substance at range, ring herself in floating liquid blades for defense, and mend her own injuries rapidly without resorting to Kaido. Should she suffer a fatal blow, the fluid scatters and vanishes without a trace.

As the tool of the Fourth Division's captain, Minazuki's Shikai carried and mended the wounded in the aftermath of the Soul Society conflict, ferrying casualties inside its stomach and later releasing them near the Sokyoku stand for her subordinates to tend. Its Bankai, long kept hidden, was finally unveiled during Unohana's climactic duel, its blood-like tide clashing against another blade without losing its shape.
