a Katana with a blue handle and a circular guard with a brown sphere or bag attached to it. Along the length of the blade is a gauge.
· Healing: Hisagomaru unlike common Zanpakutō does not inflict damage when the blade hits a target, but rather heals the wounds of anyone it touches. Upon contact with a target a red smoke is emitted from the wound as it heals. The red smoke then enters the blade causing its gauge to fill up with a red light consistent with the level of the injury. Smaller wounds will barely fill the gauge at all, while Encroachment is great enough to instantly fill the gauge.
- Shikai: the Shikai command is "Fulfill". When the gauge is full, Hisagomaru automatically initiates its Shikai and transforms into Akeiro Hisagomaru (朱色瓠丸, Crimson-Colored Gourd). In this form, it takes the shape of a scalpel.
Shikai Special Ability: Akeiro Hisagomaru concentrates every wound it has absorbed into one massive attack that is usually initiated with a slashing movement that generates a stream of red energy somewhat similar to a ki blast, extremely powerful. Subsequent attacks also have the healing restriction lifted, allowing Hanatarō to attack normally after the transformation, though Akeiro Hisagomaru's form makes that difficult.
