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

Felix are humans with high intelligence and immortal bodies. 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.
