Chiako was an attractive and busty girl with long scruffy brown hair and a yellow headband.
Chiako is seen at the beginning of the story arc during a early morning physical exam. She points out to her friend Sayaka Yumi that they were being watched by Naojiro Abashiri, which was making Chiako nervous. Annoyed at this Sayaka goes over to beat him up, but to the surprise of both of them Miki Makimura confronts him instead. Naojiro continues to hit on her only for Akira to come down from a tree and beat him up. Afterwards Miki slaps him for dealing with it violently. Chiako laughs at this saying to Sayaka how funny Akira and Miki's relationship was only to see Sayaka completely enthralled with Akira.
