Healin' Good Precure, Healin' Good Precure

Nodoka Hanadera, a weak but optimistic middle school student, has just moved to the city of Sukoyaka, known for its clean air. She quickly befriends two classmates: Chiyu Sawaizumi, kind-hearted and energetic, whose family runs a hot spring inn, and Hinata Hiramitsu, the fashionable daughter of a veterinarian.

Upon arrival, Nodoka finds a sick puppy in a forest, surrounded by three magical talking creatures: Rabbirin, Penguitan, and Nyatoran. They inform her that the puppy, Princess Latte, can only be cured by defeating a nearby monster called "Mega Byogen" and purifying the contaminated area. Despite feeling powerless, Nodoka refuses to give up and puts Latte through the battle.

Driven by her determination, Rabbirin forms a pact with Nodoka, allowing her to transform into a superhero called Cure Grace. With her newfound powers, Nodoka fights against the Byogen and heals the earth, saving Latte.

As the Byogen and their leaders continue their attacks, Penguitan and Nyatoran also find their partners in Chiyu and Hinata, granting them the corresponding powers of Cure Fontaine and Cure Sparkle. Now, the three Precure and their animal friends must stop the Byogen and protect the earth from their contamination.
