Deidoro is a very skinny and bony but muscular man with greasy black long hair, reaching just below his shoulders, circular- and rather deep-set eyes, and notably straight teeth. Like all members of Shie Hassaikai, Deidoro wears a mask, his one being plain and having drains fitted into the eye-holes so that the alcohol he consumes can drip through. Aside from that, Deidoro wears nothing but a furry vest and dark pants with black shoes.
