Neko Rinbu

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

Description
After releasing Haineko, Rangiku envelops her opponents within a cloud of ash. By moving her hands, Rangiku causes the ash to swirl around in a tornado-like formation, trapping any enemies within the cyclone.

Though Rangiku states escape is not optional once the opponent has been trapped inside, this technique was easily countered by three simultaneous Cero from three different Fracción.
