It makes you sit with the ugly part of mecha fiction: somebody signs the contract, somebody gets paid, and the ruined world stays ruined. This is a private military company working the ground the regular army resents them for holding, and that friction, corporate guns versus uniformed pride, does more dramatic work than most shows get out of a villain. The war already happened and it wrecked the environment, so the sci-fi here isn't spectacle, it's cleanup labor with racial tension and immigration politics baked into who gets to live where. Reviewers keep calling out the animation for good reason: the action sequences are where the budget lives, clean and heavy in a way 2009 TV mecha rarely managed. Be honest about the front end, it takes a few episodes to grab you, and the premise itself isn't reinventing anything. Stick with it and the plot turns start landing, and twelve episodes later you'll be annoyed nobody talks about this one.

Set after a war that left the environment in ruins, the story centers on the members of a private military company. An uneasy strain runs between these contractors and the regular armed forces. The show is a science fiction action series in twelve episodes, and its Mecha label points to piloted machines playing a part in the fighting.
