Kiryuu Michiru

Kiryuu Michiru was a denizen of the Dark Fall and is always together with her sister Kaoru with who she guards the infiltrated Fountain of Sky. Together with Kaoru, they meet Hyuuga Saki and Mishou Mai at The Sky Tree and in an attempt to infiltrate Pretty Cure, attend Yuunagi Junior High as exchange students. She and her sister eventually end up befriending both Saki and Mai and later assists Pretty Cure in taking down the Dark Fall.

History
Later on, Michiru and Kaoru were forced to fight their friends, Hyuuga Saki and Mishou Mai. Instead of fighting, because of their newly gained friendship with the two, Michiru and Kaoru sacrificed themselves to rescue Saki and Mai from their leader, Akudaikan. As a result of this, all memories of them in the Land of Greenery disappeared.

After the Dark Fall manages to steal the Fairy Carafe, and resurrect all the defeated denizens, Michiru and Kaoru are revived and join foeces with Saki and Mai against the Dark Fall.

The two sisters decide to go confront Akudaikan, without Pretty Cure, but they follow them. During the last battle, the Sky Tree grants Moop, Foop, Flappy, and Choppy new power, enabling Saki and Mai to again become Cure Bloom and Cure Egret, and Michiru and Kaoru get the powers of the Moon and Wind respectively. They defeated Goyan together with Spiral Heart Splash Star.

Power of the Moon
In the last battle, Michiru gained the power of the moon as Hyuuga Saki reverted to Cure Bloom. In this form, Michiru performed Spiral Heart Splash Star with Cure Bloom, Cure Egret, and her sister, Kiryuu Kaoru, who had gained the power of wind.
