After suffering a devastating attack from the Zerg, humans spent several years cultivating a new generation of geniuses and training them as warriors to resist another attack by the Zerg. The best and smartest young people on the planet are selected to join the combat school built on the orbiting space station, where they will compete with each other to become the commander of the international fleet.

The laser training in the zero-gravity combat classroom also proved that he has excellent tactics and physical fitness. Ander's special talents also aroused the jealousy of other new students. Battle School Commander Colonel Graff () will be isolated from other children Andrew, in order to sharpen his unique leadership qualities.
At first, Ander was squeezed out, but with his incredible understanding of human nature, he gradually became mingled with his teammates, and soon he was promoted to the military academy on a distant planet for further study, which was once used by the Zerg as a frontier for invasion of the earth.
