haineko (shikai)

The Zanpakuto of matsumoto rangiku, Squad 10 Lieutenant in the popular anime/manga Bleach. Haineko has the ability to turn Rangiku's blade into ash, which will then spread around her opponents, then with a flick of her wrist, the ash is able to cut as if it was her sword. However, the less ash is on/near an opponent when Rangiku slashes, the less damage it will do.
