Cure Ciel

Cure Ciel (キュアシエル Kyua Shieru) is a supporting character from the Rainbow Pretty Cure Trilogy. She was the Pretty Cure of the Blue Rainbow. Prior to the beginning of the show, Cure Ciel was defeated by Diabolos and was taken prisoner, but just before that, she sent out seven fairies to Earth to look for the other Pretty Cures of the rainbow. Her partner was Sapphire.

Defeat and Capture
Cure Ciel was lying on the ground, panting heavily. Seven fairies flew to Cure Ciel's side, and Sapphire asked why she continued to fight back despite her injuries. Cure Ciel claimed that as one of the warriors of the rainbow, it was her duty to defend the world. Sapphire, crying, said that if only the other warriors were here, then Diabolos would be defeated quickly. Cure Ciel smiled weakly, and said that was the very reason she was giving the fairies a job. She asked them if they would find the other warriors, and just as Sapphire agreed, a man appeared. Cure Ciel told the fairies to quickly fly away, and as they did, the man picked up Cure Ciel and disappeared. Sapphire, with tears in her eyes, quietly asked Cure Ciel to wait for her, and then flew away with the other fairies.
