Shirosora Hiroto is a minor character in the Sky Pretty Cure Series. He is Diamond's father. Though he was mentoined many times, his first real appearance was in The Final 13. He and Chinatsu are often away due to their jobs. As their jobs are quite similar, they tend to travel a lot. Hiroto is an archaeologist. Even if they are away for more than one year, they care a lot for Diamond and send her postcards almost every day.
- Shirosora Kumiko - Hiroto's mother.
- Shirosora Chinatsu - Hiroto's wife
- Shirosora Diamond - Hiroto's daughter.
Shirosora (白空?) - Shiro (白?) means white, a reference to Diamond's alter ego as Cure Whitney, and her theme color, which is white. Sora (空?) means sky, which would fit the season's theme. Together, his name means "White Sky"
- In SkPC28 it was mentioned that Hiroto loves when Diamond's hair is tied to twintails.
- This might be the reason why she prefers to keep them in twintails.
