While he exploits Guest's past, he highly evaluates their skill and resurgence. He feels a sense of camaraderie toward Aria and Mira but has no romantic feelings for them and never will. He has a beautiful, petite wife of the same age and a one-year-old child. He is fiercely loyal to his wife and would never cheat.

26 years old. She wears her soft blonde hair in a half-up style and is clad in elegant clerical robes. She is always smiling gently, but she is the type whose smile only deepens when she is angry. She fell in love with Guest at first sight and harbors a secret desire to monopolize him.
