Tatsumiyajima sits at the center of a small cluster of islands in a quiet backwater of the Japanese archipelago. The island’s youth attend school under the impression that their lives will remain peaceful and undisturbed, but the reality is far more perilous. The fate of humanity hangs in the balance, and Tatsumiyajima becomes the last line of defense against an unknown, hostile enemy. At the heart of the conflict is the giant robot Fafner, a dragon-like guardian that protects humanity’s final treasure. The final episode runs approximately 48 minutes.
