Inhuman beings hide among us. Tokyo, 2048. The northern hemisphere is now connected by the Eurasian Railroad, which deposits all manner of crime and vice here at its eastern terminus. Night after night, the megalopolis is gripped by fear as bodies turn up mutilated in ways unthinkable for a human assailant. Remorseless killers stalk the shadows-but one man stalks them! He is ORIGIN. And he is not what he seems.

You got a death wish, Tanaka-? To carry out his new central dogma-“protect Mai Hirose”-ORIGIN dons his exo-muscle armor and charges into battle against wave after wave of identical GON replicas. Victory seems within his grasp, until a powerful new foe bursts onto the scene. With the Kyoto A.I. Institute coming down around his ears, flight is ORIGIN's only chance at survival-but for Mai's sake, he will overcome his programming and fight on, armed with a new weapon: an independent WILL...!

I know what you really are-! As he demolishes one identical GON-BOT after another, ORIGIN's own body is slowly but surely brought to the brink. But even when the massive GON PRIME bursts onto the scene wielding unimaginable destructive power, ORIGIN exercises his newfound will to prioritize protecting Mai Hirose over his own survival. Physical power isn't everything, though-and the knowledge of GON PRIME's true identity might just give ORIGIN the edge he needs!

What is it I'm fighting for? Director Yamada's nefarious plan to steal a cutting-edge AEE military robot and kill his co-conspirators goes south when they hit on the same idea. Dragged into the middle of the conflict, a disguised ORIGIN must follow his programming and minimize casualties, despite being faced with the uglier side of the humanity he is compelled to save. If ORIGIN can survive this battle with the strongest military bot in the world, he just might find a new cause to fight fo...

Father, this world isn't beautiful in the slightest. The death of Mai Hirose has finally awakened selfhood and emotion within Origin-but all he feels is endless sorrow and a consuming, fiery rage. Hell-bent on exacting vengeance for the woman he had sworn to protect, Origin infiltrates the underground hideout where his robot siblings await, leaving a trail of destruction in his wake…!

What is ORIGIN up against-?! Having destroyed DA, ORIGIN is suddenly ambushed by the murderous robot's compatriots SON and GON in what is clearly an act of revenge. But with neither sentiment nor ego, no robot should engage in such illogical behavior-can one among his foes truly be a robot with emotions?! Even as this desperate battle plays out in the shadows, ORIGIN has another fight on his hands: the struggle to pass as human in his day-to-day existence!

When you develop emotions, will you fall in love with me? Nothing can change Mai's feelings for Origin-not even the revelation that he's a robot. After a narrow escape from a deadly foe, they go on the run together, Origin pledging to protect Mai no matter the cost. But even in the snowy reaches of Hokkaido, their pursuers are hot on their trail-!!

Seems you've grown fond of me, Mai. With their massive political pull, AEE has managed to thoroughly cover up Gon's assault on the Kyoto facility. Now, assembling a team to analyze the remnants left at the scene, they're well on their way to discovering the truth-that mysterious robots live in secret among the human population. At the same time, Origin has determined that for Mai's own safety he has to reject her affection so harshly that she'll keep her distance from him forever…

The final battle awaits-ORIGIN has reached the heart of his enemies' hideout, but one thing stands in the way of his showdown with Masamune-his old sparring partner SON. And what's more, she has transcended reality itself and achieved an unparalleled level of superhuman power. Can ORIGIN find a way to defeat the most powerful being in the world…?!

If I don't do something, everyone's going to die. Origin arrives in Kyoto with Mai and Dr. Fermi, only to find the director of AEE's A.I. Institute recalcitrant at best-but that's the least of their worries after Origin's robot brother GON shows up and goes on a merciless rampage! Committed to protecting Mai but unable to reveal his true identity, Origin must make a deal with the mysterious “data-mind” Y in order to find a way out of this lethal ordeal!

Ken rescues the waitress Ji-Hae Yoo from the Galgi Gang, but the battle is far from over. After the crew is made painfully aware of just how weak they really are, Tae-soo proposes they seclude themselves on a mountain to undergo training. The training they are put through, however, is far more hellish than the five could have ever imagined. As the days turn into months, Ken's longing to see Yumin again and his eagerness to face off against the Galgi Gang only grow stronger...

Ken Kitano has lost everything. He's lost his family, his dreams, and even his first crush, Yumin, who suddenly left for Korea to pursue her dream of becoming a police officer. He spends his days getting into one meaningless fight after another, but one day, after learning Yumin actually managed to make her dream come true, he decides to follow in her footsteps and head to Seoul. Only, instead of becoming a cop, he ends up catching the attention of a street gang and becoming their boss! Su...
