Guncho Tsurara

is a Bankai technique used by Tōshirō Hitsugaya's Zanpakutō, Daiguren Hyōrinmaru.

Description
Hitsugaya freezes the water around him, forming an array of icicle-like daggers that floats around him in formation. Then, by swinging his Zanpakutō in an arc, he launches the daggers at his target with high speed. The daggers are powerful enough to break through thick ice with ease whilst retaining their speed and trajectory.
