Ep. 1: Tsubomi dreams of Cure Moonlight's defeat and meets Erika in Kibōgahana before becoming Cure Blossom

1

Tsubomi Hanasaki experiences a recurring dream where Cure Moonlight falls while protecting the Tree of Hearts from Professor Sabark and Dark PreCure, prompting the fairies Chypre and Coffret to seek a successor. Tsubomi relocates to Kibōgahana and encounters Erika Kurumi, a classmate attempting to help the shy girl transform her image. Tsubomi rejects Erika’s aggressive approach, leading to criticism from Erika’s older sister Momoka, whom Erika envies. In the park, Tsubomi meets the fleeing fairies and witnesses Sasorina steal Erika’s wilting Heart Flower, transforming it into a Desertrian due to Erika’s jealousy. Remembering Tsubomi’s vision, the fairies designate her as the new PreCure, Cure Blossom, to battle the monster.
