死にゆく楽園（ほし）へ、最後のラブストーリー。

 近未来。火星付近に突如出現した“破滅の星”。その影響で地球は滅びを迎えようとしていた。

 地球統一政府は、人類の宇宙への脱出計画を提唱。そして、実現不可能に思えたその脱出計画を可能とするため、遺伝子を操作し、高い知能と不老長寿の肉体をもつ超人類“フェリクス”を生みだす。

 そんなフェリクスのひとり・“シオン”。人類を救うという目的のためだけに、彼女は100年もの間、孤島に建つ洋館に囚われていた。自由を求めるシオンと、彼女を鳥かごに閉じ込めている地球統一政府軍の兵士・“榛名亮”。

 2人が出会ったことで始まる、地球で最後のラブストーリー ―

In the distant future, a gigantic energy mass called the "Star of Destruction" suddenly appears near Mars. Its presence causes abnormal weather and tectonic plate shifts on Earth. As resources become scarce and populations have nowhere to go, conflicts erupt worldwide. This, however, is merely an omen of things to come.

Only a hundred years remain for humanity. They plan 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, which will allow the project to be implemented. Evacuating Earth becomes a top priority, and the order of "sacrificing the few to save the many" is implemented. Authoritarian rule controls the masses. Armed force oversees states and non-governmental organizations that oppose the new world order. The overwhelming military power maintains order regarding race, religion, food, energy, etc.

The second is the "Felix Project," which will serve as the foundation for the exodus plan. With only 100 years left, humanity needs to build a spaceship to leave the planet and acquire the technology to survive in the vacuum of space for a long time. They decided to create "Felix," genetically modified people with extraordinary intelligence and longevity. These "superhumans" will be able to complete the seemingly impossible project.

99 years pass.

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

Their meeting sets the story in motion.

The final love story on Earth.
