But when old Mr. Takazawa become the test subject for the Z-001 machine, Haruko questioned both the tactics of the hospital and the moral implications of the machine. This is just the beginning, as Haruko has not just the hospital, but the odds against her. But then, she discovers an odd quirk about the machine: it uses a biochip, and it eventually acquires a mind of its own!

Continuing where the first season left off, the sudden increase of Thanatos with the disappearance of the Aube Hunters has now left Arcadia in ruin.

Six months had already past since Hidamari mansion burned to ashes, the Aube Hunters, once hailed as heroes, is now blamed for the appearance of Thanatos. Nevertheless, hope still exists for the reappearance of the Queen's Egg one day, who will become the savior of Arcadia. Unknown to many however, the Aube Hunters have actually been silently waiting for the awakening of Angelique, who has been asleep the entire time.

Prior to the events of the anime, three factions—the Garan Army, the Kiba Army, and the Aira Army, battle for total dominance of Machine Island. The island is basically a prison, isolated from the rest of the world. The island contains a vast amount of resources, allowing the three factions to create an infinite supply of giant robots for their respective armies. The world government learns that the island's power reactor has become unstable and will explode within 66 hours, destroying all of life and Earth itself. The government sends the Death Caprice squad, composed of mercenaries Ken Kaido and Ryo Magami to solve the issue, along with their giant robot Mazinkaiser, but was that a good idea?
