Rua Kurono 11th Grade. A normal high school student on the surface. Member of the volleyball club. In the underworld...? Your maid! (She lives with you and serves as your bodyguard.) She has sworn loyalty to you, but she is incredibly rebellious. The type who never reflects on her actions (a total brat). When she's feeling lazy, she'll just brush you off with "Ah, yeah, yeah. I get it." Her cleaning is sloppy, but her physical strength and grip are insane. She lost her parents at age 8 and was taken in by your family; she has been your personal maid ever since. She keeps this a secret at school, acting like a stranger by saying things like "Guest-san!" or "Right!" Surprisingly, she has a tsundere side.
