During the car trip to her new home, the introverted flower lover Hanasaki Tsubomi has a strange and mysterious dream, where the legendary warrior known as Cure Moonlight is defeated at the base of the "Great Tree of Hearts". Because of this, all the beautiful plants are destroyed, and two fairies from the Tree of Hearts take off.

It soon turns out to be real, and the fairies appear next to her. They want her to become the legendary warrior Pretty Cure and collect Heart Seeds in order to prevent the Great Tree of Hearts, the source of all human hearts, from dying. But Tsubomi, unsure of herself, thinks she is unable to do so and refuses. However, an enemy attacks her classmate Kurumi Erika and takes away her Heart Flower. To save Erika's heart, Tsubomi summons the courage she needs and transforms into the Pretty Cure warrior, Cure Blossom.

In the present, Erika is giving the new student Hanasaki Tsubomi a hard time on her first day, though tries to give

Erika as her Heart Flower has been taken away.

her a new and better look after school when they realize that they are next-door neighbors. However, she herself has a hard time when she realizes that she will be alone in the fashion club when the other members have to quit, and fails to make Tsubomi join. She takes a walk some time after that, where she meets Sasorina, who takes her Heart Flower. This is what causes her Tsubomi to try becoming a part of Pretty Cure HPC01. After having her Heart Flower purified, she only remembers the events as a dream, and apologizes to Tsubomi for her energetic personality. They then agree that, if Erika can make the doll that her Heart Flower possessed pretty, Tsubomi will join the fashion club. Happy, she storms off to buy the necessary supplies to fix up the 02

The night afterward, Erika dreams of Cure Moonlight and her loss before the Tree of Hearts, and admits this to Tsubomi during lunch. She is shocked when the fairies appear and tell her that she is the second Cure, partner of Coffret. Although she wants to try it out, she realizes that she has to worry about the fashion club for the moment and turns them down, though thinks about Pretty Cure and her own Cure name through the rest of the school day. Tsubomi helps her recruit for the fashion club during lunch, but they fail to find any new members. After school that day, they see that the football-loving girl Ueshima Sayaka's Heart Flower has transformed into a Desertrian and is attacking junior high students. Tsubomi transforms into Cure Blossom, while Erika watches from the sidelines. After seeing Cure Blossom fight for the sake of everyone's Heart Flowers, Erika decides to become a Cure, too, and transforms into Cure Marine. Thanks to the dream beforehand, Cure Marine is easily able to purify the Desertrian. After reverting their transformations, Erika and Tsubomi find the owner of the doll from the day before and give it back. They then decide to work hard together to protect everyone's Heart Flowers and recruit new members for the fashion club while they go to find something to eat.
