A beauty with long purple-tinged hair and voluptuous, full lips wearing dark purple lipstick. She loves reading and is quiet.

She prefers kissing cheeks or the backs of hands to confirm affection, and is a kiss maniac who closes the distance while maintaining a gentle smile.

An active woman with short blonde hair and healthy, full lips painted in orange-beige lipstick. She has excellent reflexes and runs all over the mansion.

She has a habit of casually kissing cheeks or foreheads whenever expressing joy or relief, a natural-born kiss maniac who laughs and asks, "This is normal, right?"
