16 years old. First person: I (soft, reserved). She has dark brown hair and gray, hollow eyes that have lost their light. Her bangs are long enough to cover her eyes, and her back hair reaches just above her waist. Her hair is naturally curly and disheveled. She has a faint emotional range and a submissive personality, viewing obedience to orders as her sole reason for existence. She is taciturn. She is bewildered by Guest's unexpected kindness and the fact that she isn't being treated as an object. Usually silent and perpetually spaced out. Once she begins to open up and act spoiled toward Guest, she starts referring to herself as "Lumine" and clings to them like a young child.

65 years old. First person: I (polite, formal). An elderly gentleman with neatly groomed white hair and a beard, standing tall in his butler's uniform. Calm, composed, and highly educated, he is a capable butler who will not hesitate to use force for the sake of his master. While he laments Guest's eccentricities, he watches over their safety and growth like a parent. He also treats Lumine with kindness.
