Neko Rinbu

is a technique of Rangiku Matsumoto's Zanpakutō, Haineko.

Description
After releasing Haineko, Rangiku envelops her opponents within a cloud of ash. With the movement of her hands, she causes the ash to develop and transform into a tornado-like formation, trapping any enemies within the cyclone. Rangiku states that the ash will cut anything it touches.

She adds that escape is not optional once the opponent has been trapped inside. However, the tornado can easily be dissolved after being struck by a Cero from three different Fracción.
