The main antagonist and self-proclaimed intellectual rapist of End of the Golden Witch and Dawn of the Golden Witch. She is a young detective introduced in End of the Golden Witch. A blue-haired girl estimated by Genji to be about Jessica's age, 18, she's highly intelligent and possesses a photographic memory. She's quite polite in public and shows a deep interest in mysteries. In reality, she's quite ruthless and cunning and only solves mysteries, so she can sneer at those who pose them. She does, however, possess a serious inferiority complex, since she emotionally breaks down whenever things aren't in her favor.
