In the far future, a huge mass of energy suddenly appears near Mars, which causes unusual natural phenomena. As a result, wars and terrorism occur all over the world.

One is to form the World Integrated Government to gather resources and suppress antis. The other is called the "Felix plan".

Ninety-nine years later, a Felix girl named Sion who devotes her whole life to humans' plans has accomplished all her tasks and decides to stay on Earth for the rest of her life.
