Yohko's best friend. Chi (her nickname) seems to have an extensive information gathering network and tends to know about most of the events going on at the school. She usually supplies Yohko with info (sometimes pictures) on the most handsome guys. She employs herself as Yohko's "manager" and assist Yohko where she can, although she does tend to get herself caught in the line of fire.
