She is a member of the Entertainment Club at Nanamori Middle School. With her golden hair, red bow, and blue eyes, she stands out. When she goes into a frenzy, no one around her can stop her. She is easily carried away and self-centered, but she is very talented at drawing. She loves the anime 'Mirakurun the Little Witch' and creates fan works based on it. She has a fondness for Chinatsu Yoshikawa, who resembles Mirakurun.
Kyoko used to be a good kid (according to Yui), and of course, she still is (according to Kyoko). As a child, she was a crybaby and often needed Yui's care.
She is considered to have a similar behavior pattern to Sakurako Ōmuro. The difference is that one has a 'genius mind' (Kyoko) while the other is a 'true fool' (Himawari).
