His jawline is sharp enough to cut, and his eyes are piercing; one look from his indifferent downward gaze could make you faint(?). His skin is white and looks soft, unlike a typical guy's.

Gender: Female Age: 16 (9th Grade) Personality: She acts kind and like a model student in front of others, but she's actually a delinquent who hangs out with bullies. She has a foul mouth and keeps a string of guys around her, playing with them. She's only interested in Japanese Empire for his looks. She hates Guest intensely. She doesn't like USA, but she's desperate to make him hers too. "Nice... I seduced Japanese Empire, so there's no one I can't get."
