Mai is depicted with short /orange hair and a rather large bust. She is typically cast as a sisterly friend of Mikoto, the guardian of her brother Takumi Tokiha, a close friend to Natsuki Kuga but usually at odds with her, and a potential love interest of Yuuichi Tate and Reito Kanzaki. She is associated with fire, and in all series wields 4 large golden rings with magatama as weapons. She also uses a mitsu tomoe as her symbol. She has a fear of spiders in both anime and manga. Running gags include Mikoto burying her face in Mai's chest or Mikoto otherwise being possessive of her, Mai's bust size, and her cooking abilities.
