Top wo Nerae 2! Diebuster (2004)

Generations have passed since the war with the Space Monsters started, and none remain who know how it began, with even records of those times being scarce. It is a lost cause, but humanity still fights against them, relying on the "Topless": a group of elite space pilots with special powers that allow them to use the Buster Machines—the last hope against the Space Monsters.
