Becoming Cure Treasure
Kelly was hanging out with her childhood friends, Aihara Ichigo and Suzuki Ayano. The three were very close to each other, however, Kelly didn't realise that Ichigo and Ayano were hiding a secret from her. When it was after school, Kelly and her twin brother, Kyle, said goodbye to Ichigo and Ayano, and Kyle said that he has realised that the two were hiding a secret from Kelly. Kelly, furious, caught up with them, confronted them and demanded that they tell her the truth at their mothers' shop, the Eternal Wedding Shop, however, Ichigo and Ayano refused. Suddenly, a yellow bunny appeared and a pink dog jumped out of Ichigo's bag and started hugging the bunny, and a blue cat came out of Ayano's bag. Kelly became confused, and before Ichigo and Ayano could explain everything, the bunny began talking, and said that her name was Crystal, and she wanted to find a human partner. She asked Kelly to be her partner because her love of weddings was so great, but before she could answer, a commander from Midnight appeared, and had started attacking with a Namida. Ichigo and Ayano told Kelly to keep a secret, and they then transformed into the Pretty Cures of Love and Wisdom, Cure Rose and Cure Serenity! But the Cures were struggling to defeat the Namida, so Kelly asked Crystal to make her a Pretty Cure. Crystal, excited, agreed to Kelly's decision, and Kelly transformed into the Pretty Cure of Happiness, Cure Treasure! With a song she wrote, she purified the Namida and joined Rose and Serenity. Now the three girls together make the Wedding Love Pretty Cure!

"The energetic wedding flower of happiness and courage! Cure Treasure!"
Kōfuku to yūki no enerugisshuna kekkonshiki no hana! Kyua Torejā!
Cure Treasure (キュアトレジャー Kyua Torejā) is the Pretty Cure alter ego of Kelly. She controls the power of light and happiness. She can transform by saying the phrase, "Pretty Cure! Lovely Kiss Change!" Her main attack is Treasure Solution.
Treasure Solution (トレジャーソリューション Torejā Soryūshon) is Cure Treasure's main attack, which can be used by shouting a special phrase to activate it, which is "Dreaming, loving, courageous, caring! Show the world what happiness can do!"
Light Festival (ライトフェスティバル Raito Fesutibaru) is Cure Treasure's most powerful attack, which can be only be used in her Eternal form.
Wedding Lumiere (ウエディングリュミエール U~edingu Ryumiēru) is the team's first group attack, which can be used with the Eternal Love Wands and in their Wedding forms, and is activated by a special phrase, which is "Sparkle with your hearts, weddings of the future!"

Nishimura (西村): Nishi (西) means "west" while Mura (村) means "village".
Kelly (ケリー): Kelly is an American name that means "warrior". It is also an Irish name that means "war".
So therefore, Nishimura Kelly means either "western village warrior" or "western village war". This could be a pun seeing Kelly's ADHD kept her alive, and she become a great warrior of Pretty Cure. Yoichi is also in the West, and Kelly lives in Yoichi.
Cure Treasure means an important item in someone's life, just like her friends and family were important to Kelly.
