Becoming Cure Tulip
Hana was at her school and was getting ready to go home, when a member of the school newspaper committee, Yukimura Yuriko, tried to take a video of Hana, wanting to know her secrets on how to take care of a garden so well. Hana grew scared, but Yuriko's twin sister, the Student Council President, Yukimura Ami, informed Yuriko that Hana hated being in the spotlight, and that her secrets were so private, she wouldn't share them. Yuriko left the classroom, and Ami winked at Hana. Hana left the school, and heard a cry from the sky. She looked up, and a squirrel appeared. Hana knew this squirrel wasn't a real one, because it was green. The squirrel then spoke to Hana, which surprised her. The squirrel said that her name was Bloom, and that she was once the fairy messenger of the four princesses of the seasons: Spring Tulip, Summer Flame, Autumn Maple and Winter Snowflake. Bloom then told Hana that she knew Hana had been having strange dreams about a girl pleading for her to awaken quickly. The girl was Spring Tulip, the princess of flowers and hope, and Hana was the reincarnation of Spring Tulip. Suddenly, an evil commander of the Dusk Area, named Stone, appeared, and saw Ami walk past. He summoned a Shard of Darkness and shot it into Ami's neck. Ami then faints, and with a few words, Stone turned poor Ami into a monster, called a Hidoi. Bloom then said that Hana could save Ami, and Hana said that even though she was scared, she refused to let anyone hurt an innocent person, and that Ami didn't deserve this. Bloom then said that Hana's strong feelings helped Bloom to sense the power of Spring from her, and that she was able to become a Pretty Cure. Hana agreed, and then, her Season Heart was permanently taken out of her body and changed into a Season Heart Palette. She then transformed into the Pretty Cure of Spring, Cure Tulip!
