Strix is a young woman with long dark purple hair, pale skin, and dark violet eyes.
As "Tsukuyomi", she wears a school uniform consisting of a long-sleeved shirt with white accents and long pleated skirt colored identically to her eyes, a mulberry pink tie, long black socks and brown loafers. Strix wears a lily in her hair in this outfit, one that she grew herself.[2]
While part of Bankikai, Strix had her hair in a ponytail and wore a grey short dress on top of an identically-colored bodysuit that left her bust area exposed and held together by eight belts. With her, she wielded a gun and needles given to her by Ogre for self defense.[3] This uniform, which was worn by Zohar too, was designed by him as well.
