Living up to its name as the most beautiful Zanpakut� in Soul Society, Sode no Shirayuki manifests herself as a beautiful woman dressed in white and light blue clothes. Her hair is pale blue and she speaks softly. In its released state the blade becomes completely white and a ribbon forms from the pommel, earning it the recognition as the most beautiful zanpakut� in Soul Society. Sode no Shirayuki utilizes ice to attack, each of its three abilities being labeled as "dances" by Rukia. "First dance, white moon" (��舞・月白 some no mai, tsukishiro) denotes a circular area around Rukia's target and freezes everything within the circle from the ground upwards until it reaches the sky.
