In her turnover costume, she dons a uniform composed of a yellow vest, green plaid skirt, and a white shirt with green tie. Around her neck is a small red bandanna worn like a scarf. She has red armguards on her forearms with bandages underneath, and straps around her waist to hold her two swords. On both legs she wears thigh high socks and brown formal shoes.
