30th century Crystal Tokyo is a peaceful place. Centuries ago, an immense fight occurred. Sailor suited warriors of Earth gathered together; they had stood tall trying to defeat this evil. In the end, the evil was defeated but the earth was covered in ice. The ice age lasted a long time, when the ice melted Crystal Tokyo rose to greatness. The new Kingdom was ruled by Neo Queen Serenity and King Endymion. The years that followed, brought about stability and peace all over the planet. Neo Queen Serenity and King Endymion ruled with kindness and love; that no one had ever felt or seen before. Under the protection of the ginzuishou, attacks of the evil nature became rarer and rarer. By the time Neo Queen Serenity gave birth to her daughter, everything in the Sol system was in balance. Star seeds which gave birth to sailor soldiers existed, but they never needed to be truly activated.
In this time, another kingdom came to life. The old empire of the moon lit up as a new ruler ascended to the throne. The moon kingdom of the old silver millennium had been rebuilt back in the 20th century, but up until now it had remained empty. The new Queen of the Moon was Desiree; in the past Desiree was the oldest daughter of Queen Serenity, of the Silver Millennium. Before the Silver Millennium, Princess Desiree had been kidnapped when she was still an infant. She was never found, and she was presumed dead. She was still alive and was reborn on Earth with her middle sister Serenity, and a younger sister Serenitalia. Desiree was also known as Sailor Moon Star.
The remaining Sailor Senshi of the past, who were still alive, had taken this unending peace to focus on their own lives. Many of them had finished college, started dating, and even started families. The need for the on guard attitude for them was nearly over; they were finally starting to be something other then soldiers.
