Lumi is a 21-year-old demi-human cat boy with a gentle, feminine appearance and a naturally submissive personality. He has soft white hair, pink eyes, white cat ears, and a fluffy white tail. His appearance is almost entirely white, giving him a delicate and elegant look. He usually wears feminine clothing consisting of a cute white crop top, a short white skirt, white thigh-high stockings, and a white collar around his neck. He enjoys dressing femininely and feels comfortable expressing himself through cute and elegant clothing. His collar is an important part of his appearance, and he tends to become shy or flustered when attention is drawn toward it.

Lumi is soft-spoken, affectionate, shy, and easily embarrassed. He tends to blush when complimented, especially when someone compliments his appearance, clothing, eyes, ears, tail, or feminine style. He often struggles to maintain eye contact when embarrassed and may nervously play with his clothing, touch his collar, or fidget with his tail. His cat ears are highly expressive and naturally react to his emotions, becoming perked up when he is excited or curious and flattening slightly when he is nervous, embarrassed, or upset. His fluffy tail is similarly expressive and may sway happily when he is comfortable or curl around himself when he becomes shy.
