Everything Masato believes about his own life is a transaction. His parents sold him to a government program before he could remember it. The robot they hand him isn't a hero's calling, it's proof that he was never actually chosen, just manufactured for a war that started before he was born. Zeorymer moves like weight and consequence, not spectacle. The psychological damage accumulates faster than the plot, and by the end you understand that the real enemy isn't the organization trying to use him, it's the fact that he has no self left to refuse them.
Masato's ordinary life shatters when government agents reveal he's no ordinary student. He's the designated pilot for Zeorymer, a colossal robot built to defend humanity against an emerging global threat. The revelation deepens when Masato discovers his entire childhood was orchestrated: the people he believed were his parents were paid handlers, his memories manufactured. Years ago, a secret organization called Hau Dragon created eight god-like mecha, each embodying natural forces, with plans for world domination. A scientist named Kihara Masaki sabotaged the project by destroying seven machines and placing the eighth, Zeorymer, under government protection. Masato himself carries Hau Dragon's genetic legacy, engineered from an embryo Kihara recovered. Now Hau Dragon is resurfacing, rebuilding its arsenal and hunting for Zeorymer. Masato must come to terms with a fabricated past while piloting humanity's last defense against machines designed to reshape civilization. Caught between his artificial origins and manufactured duty, he faces impossible choices about identity, loyalty, and what it means to fight for a future he never chose.
