Mazinkaiser SKL - S01

Before the story begins, three rival forces-the Garan Army, the Kiba Army, and the Aira Army-fight for control over Machine Island, a remote prison cut off from the world. The island holds vast resources, letting each faction build endless armies of giant robots. When the world government discovers the island's power reactor is unstable and will detonate in 66 hours-wiping out all life on Earth-they dispatch the mercenary team Death Caprice. The squad, made up of Ken Kaido and Ryo Magami, arrives with their giant robot Mazinkaiser to stop the disaster. But whether that was the right move remains to be seen.
