Some no mai, Tsukishiro

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

Description
Rukia calls out the name of the dance while holding her Zanpakutō upside down. The blade glows and then she makes a slashing motion when her target is in position. When she does this, she draws a circle with the tip of Sode no Shirayuki, the space within that circle and anything inside freezes. The circle not only freezes the ground, but everything within the circle's influence including anything above it up in the air, creating an extending pillar of light that then freezes everything within the circle. Shortly after being frozen, the victim then shatters along with the ice. The ice pillar won't shatter if the victim isn't caught within it.
