Sennen Hyōrō

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

Description
Hitsugaya creates many ice pillars which encircle him and his enemy. At his command (when he turns his sword 90 degrees counter-clockwise), these pillars then move towards the enemy, enveloping and crushing them. Though this technique is very powerful, Hitsugaya infers that it takes a considerable amount of time to prepare, and therefore the distraction of his enemy is crucial in successfully completing this attack.
