- Prism Pretty Cure! was created from the desire to create her own fan-made Pretty Cure series and since Mirai was bored and wanted to spend her time actually doing something. The series got the name "Prism Pretty Cure!" randomly.
- Many changes to the series were made after figuring out how Japanese names worked (ex. Yukimura Aiko was previously Yukino Aiko; both were first names).
- Jewel Hearts are similar to Futari wa Pretty Cure's Prism Stones as well as the Cure Icons of the season.
- The Prism Communes shares similarities with the Card Communes which are used in Futari wa Pretty Cure and the Lovely Communes in Doki Doki! Pretty Cure.
