The heroine of Arc-Vand Yuya's childhood friend, she is the daughter of You Show Duel School's headmaster. Where Yuya is energetic and upbeat, she is more rational, though rather quick to lose her temper. She has a habit of whacking people, particularly her father and Yuya, with a paper fan whenever she's annoyed with them. While never outright stated, there are plenty of hints of her being in love with Yuya, which are also hinted to be mutual.
