Synopsis by Cammila Collar
This OVA has little to do with the original Super Dimension Century Orguss TV series. It focuses on a war taking place on Earth between rival nations that are both searching for the Decimators: massively powerful mecha that nearly brought about the destruction of the world 200 years ago. Now Lean, a youthful cadet and Nadamura, a powerful woman, must try to change the events of the past, when the Decimators first came into being, in order to save the future.
