Fafner in the Azure: Dead Aggressor - Season 1 (2004)

When an enormous golden being attacks the peaceful Tatsumiya Island, citizens evacuate the surface to underground protective shelters. Soshi urges Kazuki to fight this horrifying adversary by piloting the Fafner Mark XI.

Aboard the Mark XI, Kazuki has a brush with death in his first battle to save the island from the Festum. Soshi tells Kazuki about the secrets of the island. Once a paradise, Tatsumiya is no longer safe from the dangers wrought on the rest of the planet.

A probe from the New United Nations has threatened to reveal Tatsumiya. As Alvis prepares to move the island to the northwest, students are drafted as new pilots and begin grueling training.

Kazuki and Soshi pursue the Festum while Alvis begins to move Tatsumiya Island. Then a New United Nations unit interferes with the plans, moving the battle directly into the island's path.

After their discovery of Tatsumiya, the leader of the New United Nations forces Makabe to hand over the Mark VI. Shoko promises Kazuki that she will protect the island as he leaves for battle. Suddenly, another Festum attacks.
