Thirteen kids wake up in a war they didn't start, separated from everyone they knew, forced to pilot a training ship that was never meant for combat. The show doesn't pretend they're soldiers, it watches what happens when children have to become them anyway, one impossible decision at a time. This is survival without heroics, childhood ending in real time, a generation raising itself in the wreckage of adult failure.

In AD 2058, aliens suddenly attack Clayad, the third planet of the Ypserlon system, 43 light-years from Earth, and its settlers are forced to flee. In the chaos of the evacuation, a group of children lose track of their parents and end up aboard Janous, a training spaceship. After many sacrifices they reach Belwick, the system's fourth planet, only to find it already caught up in war. With no adults to rely on, the thirteen children set out for Earth by themselves in this mecha science fiction series.
