Aomizu Yuki is a minor character of the Sky Pretty Cure Series. Yuki is Sapphire's older brother, who is not just excellent at the keyboard but also good at repairing technical stuff. So every time something breaks, Sapphire asks Yuki for help.
- Aomizu Sapphire - Yuki's younger sister. Both Yuki and Sapphire show that they love music. Its possible that Yuki might be the reason Sapphire got into music in the first place. However, today Sapphire is way better in terms of making music than he is.
- Midorikusa Tsubaki - One of Yuki's friends. Tsubaki is a class under Yuki and both are part of their school's theater club. Yuki makes the music, while Tsubaki dances.
- Fukakawa Ryota - One of Yuki's best friends. They are together in a band. He had his first appearance in SkPCRS26 when he was helping Yuki preparing the concert for Sapphire.
