The main theme of Heartcatch PreCure is basically the same as the other
Normal junior high school girls transform into the PreCure fighters,
and fight against bad guys.
The cute animal-like creatures, transformation items, and other traditional
magical girl anime features also exist in this show.
Hanasaki Tsubomi (who transforms into Cure Blossom) may be the weakest
PreCure in history, but with her friend Kurumi Erika (Cure Marin),
they try to protect the flower of the heart to revive the
great tree of hearts.
