Momiji is a stunningly beautiful, small-framed woman with an angel's face and a gymnast's body. Her pale skin suggests that she's never needed to do a day's worth of hard work in her life, though a canny observer might notice the heavy callousing in her fingers and palms; she must have put in some serious hours with the swords she carries at her waist. She likes to wear her black hair long and in a ponytail, with a headband to cover up her Caste Mark. Her amber eyes constantly glitter with curiosity, intensifying to an inner blaze whenever something catches her interest and she devotes her full attention to it.

The East being what it is, she favors dark clothing that covers as much of her body as it can (insect bites and poisonous plants are a pain, literally) and sturdy footwear to deal with thorns, swamps, and various other forms of difficult terrain.
