Tatsumiyajima is the central island in the middle of a small cluster of islands, in a sleepy backwater of the Japanese isles. Not much happens there, and the island's young people go to school knowing that their lives are likely to remain peaceful and undisturbed. Or so they have been taught... but the truth is different. The fate of mankind is on the line, and Tatsumiyajima is the last line of defense against a hostile and incomprehensible enemy. At the center of it all, fighting for Humanity's continued existence, is the giant robot Fafner, the dragon that guards this final treasure of mankind. Note: The last episode aired with a runtime of ~48 minutes as opposed to the standard 24 minute long episode. In the DVD release and subsequent home video releases of the series, the final episode was split into two separate ~24 minute long episodes.

July 2008. Mankind was faced with the threat of extinction. An ultra-magnetic weapon, far more devastating than any nuclear weapon known, destroyed half the world in an instant. The earth's crust was rocked by massive movements, the earth was thrown off its axis, and the five continents were torn completely apart and sank deep below the sea... The attempt by a number of people to flee to outer space failed. Their spaceships were forced back to the earth and vanished with their hopes shattered. But one of the spaceships narrowly escaped destruction and crash-landed on a small island which had miraculously survived the devastation. The crew members of the spaceship settled there, as if they were seeds sown on the island. After years, a boy was born. He was a new life in the desert, a ray of light in the darkness of the annihilated earth...

In Japan in the year 2035, an accident known as the "Burst" occurs during a research project, spawning an out-of-control artificial life form called "Matter" that has spread throughout the Kurobe Gorge. The research city that was once hailed as the hope for humanity is cordoned off by the government. Two years later, 15-year-old Aiko Tachibana, who lost her family in the Burst, learns something unbelievable from Yuya Kanzaki, a new student at her school. A secret is hidden within her body, and the answer to the puzzle lies at the "Primary Point" that was the center of the Burst. When boy meets girl with the fate of humanity in their hands, what new truth will come to light?
