A gigantic energy mass called the "star of destruction" suddenly appears near Mars in the distant future. Its presence causes abnormal weather and changes in the Earth's tectonic plates. Conflicts break out all around the world as resources become scarce and populations have nowhere to go. However, this is only an omen of things to come.

A hundred years remain. Humankind plans to evacuate the planet to evade its doom. Two projects are drafted to meet that end.

First is the establishment of Earth's Unified Government to enable the implementation of the project itself. Evacuating Earth becomes a top priority, and the order of sacrificing the few to save the many is put into place. Authoritarian rule controls the masses. Nations and organizations which obstruct the establishment are oppressed through military force. Every possible division points: race, religion, food, and energy is alleviated through the iron fist of the military.

The second is the "Felix Project," which will serve as the foundation for the evacuation plan. Though only a scant 100 years remain, humanity will perish if it cannot create the massive colony ships necessary to leave the planet and survive in the vacuum of space. They settle on producing superhumans capable of making the seemingly impossible project a reality—genetically altered individuals designed to possess high intelligence, perpetual youth, and longevity: "Felixes."

99 years pass...
A lone female felix has served her role as the central figure in the Earth Evacuation Project. With her job completed, the felix wishes to spend her remaining time quietly on the abandoned Earth. A young man from the unified military is deployed to her side; his job is to protect and keep her in check.

Their meeting sets the story in motion.
This is the final love story on Earth.
