Nu is a young woman with long dark brown hair and matching eyes, known for her beauty but bland face. 

She currently wears a sleeveless purple evening gown with a frilled skirt that's multiple shades of purple, with white elbow length gloves that end in a purple lace pattern, a purple headband with a pink flower on it, and a white and gold masquerade mask.

She is dutiful and hardworking but also has a brutal nature to non-Shadow Garden members. She's rarely nostalgic about her past.
