Ayako is 16 years old stellar athlete and captain of the archery dojo. Ayako and Rin are actively competing to see who will be the first to snag a boyfriend. She is victimized by Rider or Caster early in the story and later found unconscious in an alleyway. In the anime, Ayako is seen with Shinji after her disappearence, although Shinji denies it when asked by Shiro. Ayako often asks Shiro to come to the archery dojo and watch them practice. After she is attacked, Ayako is not seen again. soon it is revealed that she was taken by Shinji and used as source of mana to gather energy for Rider (who also sucks her blood). She survived but she was left with almost no mana and in a sort of comatose status.
