Juhaku

is a technique of Rukia Kuchiki's Zanpakutō, Sode no Shirayuki.

Description
Rukia stabs the ground, which creates a trail of ice in the direction of her intended target as small particles of ice fill the air. Freezing the target from the base up in a continuing freezing process, the ice transforms the target into ice. Parts of the target which are frozen can easily break apart or shatter.
