Kyou Toono is a supporting character in the anime Chibi Devi!. He is a teenage boy with brown hair that reaches his neck, and his eyes are typically not visible. He holds the role of the childhood friend of the main protagonist, Honoka Sawada.

In the story, Kyou is known to be an enthusiast of anime, and his viewing habits play a small but notable part in the events of the series. On one occasion, Honoka calls Kyou and their classmate Shin Sugisaki to her apartment to see the devil baby Mao. However, Kyou leaves the apartment to watch his favorite anime program, an absence that allows the baby to escape and cause trouble. He later reveals important details about Honoka's family circumstances, explaining to Shin that she lost her parents and currently lives with an aunt who is always away at work. Demonstrating his priorities, Kyou suggests that Shin should take on the role of being a father figure to Mao, claiming that he himself is too preoccupied with watching anime to do so.
