Lu Bixing is defective because his brain won't sync with Eden, the neural network that decides everything about your life. Lin Jingheng is a state weapon built to enforce that network. The show watches them collide and then asks what it actually costs when two people choose each other over the system designed to keep them apart. The mecha aren't the point, the intimacy is. Two men holding the line against a world that coded them as incompatible, and winning anyway.

In a future where a mind-link technology called Eden holds society together, one person in every hundred cannot connect to it. Those people are branded defective and pushed to the margins. Lu Bixing and Lin Jingheng are two very different men who end up fighting side by side against this unjust order. In Nova Calendar year 270, Lin, a general of the Star Alliance, is framed and exiled to the far edge of space. Five years later, space pirates invite him back into action, and he sets out on an interstellar journey with his defectives to uncover whoever orchestrated the plot against him. The ONA mixes action, mecha and science fiction.
