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. Small particles of ice fill the air when the technique is used. The ice then freezes the target from the base up in a continuing freezing process, as it transforms the target into ice. Parts of the target that are frozen can easily break apart or shatter.
