Hero Organization

About Hero Organization

In a near future where humanity teeters on the brink of extinction, armored warriors rise in the depths of space to fight monstrous creatures known as Star Beasts for the survival of humankind. Forced by looming collapse to look beyond a dying world, people turn their eyes toward the stars in search of a path forward across an expansive universe. Yet the move into outer space does not bring safety, as the vast darkness harbors an unfamiliar and deadly threat waiting among the stars. Out in the cold reaches of space, humanity encounters the Star Beasts, a menacing presence that stands directly in the way of human survival. These hostile creatures loom in the void as an existential danger to a species already pushed to its limits. Faced with annihilation on two fronts, humankind cannot retreat and must confront this cosmic menace head-on. To answer the threat of the Star Beasts, warriors clad in mechanical armor step onto the battlefield. Equipped with these mechanized suits for combat in space, these fighters serve as the frontline defense against creatures that ordinary means cannot stop. In an unforgiving universe where every clash carries the weight of human survival, they stand as humanity's last hope. Each battle pits armored fighters against the relentless Star Beasts in a struggle where defeat means the end of humankind's future among the stars. Relying on mechanical armor to endure the rigors of deep-space warfare, these warriors carry the burden of protecting everyone left behind. Across this vast cosmic frontier, the war between mechanized defenders and the Star Beasts defines humanity's fight to endure. As the battle for survival unfolds in the depths of space, those who wear the armor must hold the line against extinction.
