That and I'm taking it a step further, Kagura/Cure Tempest was actually part of the original Shinobi Stars team (which by the current series timeline first fought about 50 years ago back in 1975) but was posessed by the power of a cursed mask and became a Yoma herself. The curse also kept her from aging so therefore when she was freed later in the series  she was physically still a teenager.

In fact, the movie could even be a time travel plot where the two sets of Cures wind up teaming up with each other.
