Tsukihime (Zanpakutō Spirit)

Tsukihime (月姫, Moon Princess) is the manifested spirit of Tsukimaru Tokugawa's Zanpakutō, Hitorigami, as well as his Kitsune powers. Many members of the Tokugawa Dojo believe she is Tsukimaru's "other side", which would later be dubbed to "Female Tsukimaru" (女性月円, Josei Tsukimaru). Tsukihime is the oldest and most powerful illusion-based zanpakutō in the Soul Society.
