Yuri is the school's #1 idol as the student concil president, but she gets some unwelcome competition when Ayumi transfers in. She met Haruo when she was a little girl, and instantly fell in love. Her hair changes colour (brown to silver) when she uses her battle magic. Yuri is still in love with Haruo, hence her constant daydreaming about him, and gets irrationally angry when Ayumi is with him. As an excuse to see him she often says that Ayumi's behavoiur is "Against School Policy" and as the Student President she must see that all rules are followed
