Shinkū Tasō Hyōheki

is a technique of Tōshirō Hitsugaya's Zanpakutō, Hyōrinmaru.

Description
To counteract the small quantities of ice which Hyōrinmaru can create, Hitsugaya developed this efficient method of ice creation in conjunction with Rangiku Matsumoto's Zanpakutō, Haineko. By using the ashes of Rangiku's Shikai to create layers of ice before removing the ashes and having Haineko return to its sword form, Hitsugaya can create a multilayer ice wall with several empty layers. This enables the little ice Hyōrinmaru can create to be able to withstand fire attacks with little damage. Hitsugaya can manipulate this ice to use it as a sword.
