You watch this OVA knowing it failed at everything it tried to do. The animation vibrates like the rendering engine is having a seizure, characters flicker in and out of existence, blood pillars stand as solid geometry defying physics. What emerges from that wreckage is something accidentally transcendent: a fever dream where incompetence becomes its own kind of honesty, where nothing makes sense but the sincerity never wavers. This is what happens when ambition crashes into zero resources and nobody stops it. It's not good. It's a document of creative disaster that somehow becomes more memorable than dozens of competent shows.
A failed Mars expedition sets off a catastrophic chain of events. Alien entities called Ancients materialize across Tokyo, bringing chaos and bloodshed in their wake. A ragtag unit of four young people becomes humanity's last line of defense: three capable fighters and one unstable teenager thrust into a war they barely comprehend. As bodies pile up and the Ancients grow stronger, the team hunts for answers. Why are these creatures here? What do they want? But the truth cuts deeper than anyone expected. One of the Ancients delivers a revelation that rewrites everything: humanity might not be the natives of this world at all. The line between invader and defender blurs. Reality fractures. The four survivors must grapple with a horrifying possibility: that their entire understanding of Earth, their place on it, and the nature of the threat closing in around them has been fundamentally wrong all along. What unfolds is a brutal, disorienting journey into cosmic horror where certainty becomes the most dangerous assumption.
