Queen Juliet Chika (女王ジュリエットちか Joō Jurietto Chika) is the ruler of the Light Kingdom and the first original Cure in Prism Pretty Cure! In the series, she is the first Cure to make an appearance, identifying herself as Cure Light. She first appeared in episode 1, when Queen Juliet saw the Light Kingdom fall into darkness, while she fought against Vincent.

Before the Light Kingdom was invaded by the Shadow King
The Light Kingdom was in peace and harmony along with the people who live there. The place was ruled under Queen Juliet, who cared for love, wishes, and seeing her subjects happy. The Jewel Carriers, her servants, also known as Cake, Teddy, Wave, and Lu, were some of her friends.

Light Kingdom is taken over
After awhile the Light Kingdom is invaded by the Shadow King, he and The Six Generals had trapped the citizens in darkness. But Queen Juliet Chika didn't lose hope and fought Vincent as Cure Light. She had used all her power to seal Vincent's powers and was trapped in darkness. She summoned the Jewel Carriers off to earth.

Relationships

She always lectured Vincent on his behaviour, but was incredibly open minded. When she and Vincent became the rulers of their kingdom, Vincent was overcome by the shadows haunting his family. He and Juliet had one last battle, while she was able to seal his power.
 * Jewels Carriers / Fairies: The Jewel Carriers of the Light Kingdom.

When Cure Light activates her attack she lands her hand on Vincent's heart. While a bright white light shoots out, sealing Vincent's power.
