Guncho Tsurara

is a technique of Tōshirō Hitsugaya's Bankai, Daiguren Hyōrinmaru.

Description
After freezing the water around him into an array of icicle-like daggers, which float around him in formation, Hitsugaya swings his Zanpakutō in an arc, launching the daggers toward his target at high speed. The daggers are powerful enough to break through thick ice with ease while retaining their speed and trajectory, and can reform themselves if they melt.
