All Mototsu are similar to Humans and Shinigami, however, the one trait that stands out is their magenta within blue eyes. They are all similar to porcelain dolls; extremely beautiful, slender, flawless, and androgynous. Mototsu are genderless; though are referred to whatever gender they sound and act like. In Gai's first appearance in Bleach: Rising Phoenix, an onlooker described the seemingly young boy as having "White porcelain skin like a bisque doll, beautiful hair, big bright eyes like diamonds, and a youthful and perfect body."
