History: Lived on Mercury, on a sub dimention - Atlantis, in the Sapphire Palace. Destiny destroyed the entire planet Mercury in that dimention. To stop the apocalypses from hitting Earth, Princess Keira and Princess Yurina summoned their powers and reflected the apocalypses. Because the apocalypse was from another dimention, the people of earth were never aware of it's existance. The two headed to earth to live there until a way to restore the planet was found. Both Kei and Yuri were weak from the battle, but because Kei was always weak she died on the travel to earth.
