Fafner: Complete Series (Blu-ray + DVD)

Terrorized by a hostile alien race's mental warfare, humans hear only this question just before their lives-essentially their minds-are assimilated by the violent invaders. Kazuki and his classmates lay everything on the line to pilot their heavily-guarded island's secret weapons: towering mechanicals for which only they are genetically qualified to control. With most of Earth destroyed, humanity's survival relies on these youths' selfless determination to protect the only home they know. But when each battle pushes the pilots to the brink of assimilation, who will protect them?
