One day, a Renegade Extended carrying an unconscious little boy stumbles into his office on the run from the Security Bureau, begging for help. Though reluctant to get involved with such a matter, Juzo agrees, only to learn that things are far more complicated than they seem.

This manga features the following tropes:
- Action Girl: Mary proves to be quite capable in a fight.
- Anti-Hero: Juzo is a mercenary who's Only in It for the Money, but nevertheless comes across as fairly principled and he protects other Extended knowing it's a thankless task.
- Arm Cannon: Juzo's left arm can turn into a revolver.
- Artificial Limbs: Plenty of folks have cybernetics, most prominently replacements for limbs - to the point that it easier to count characters without any extensions.
- Badass and Child Duo: Juzo must protect the child, Tetsuro, from the Security Bureau.
- Badass Longcoat: Juzo sports a pretty cool looking duster, as befitting a Cyberpunk protagonist.
- Back-Alley Doctor: Mary.
- Batman Cold Open: Juzo chasing off Extended thugs who are bothering the local doctor.
- Chekhov's Gun: Juzo's gun head has a trigger, which he can't pull on his own. At the end of the first volume, he tells Tetsuro to do so.
- Cyberpunk: Falls pretty squarely into this genre.
- Cyborg: The Extended. Juuzo himself, in particular, seems to have a lot of enhancements compared to others.
- Evil Redhead: Karen the fake Sister who works for Behruren.
- Fantastic Racism: The plight of the Extended is that Behruren exploits this trope, portraying them as inhuman killing machines so that they don't attract public backlash for their mistreatment of them.
- Fat Bastard: A Behruren agent who comes after Tetsuro seems to be very well fed, and is a complete Jerkass.
- First-Episode Twist: Tetsuro has the power to hijack the brains of other Extended, and he was controlling the fugitive asking Juzo for help.
- Luminescent Blush: Juzo gets this despite not actually having a face, when his client kisses him chastely. It's a bit of a Running Gag when women flirt with him.
- Great Offscreen War: The Great War so far is only alluded to, not seen.
- Mega-Corp: Behruren.
- Rated M for Manly: A cyborg with a gun for a head is pretty darn manly.
- Smoking Is Cool: Juzo. Presumably Extendeds don't have to worry about lung cancer.
- Super-Deformed: The art style of Juzo's head becomes this way when feeling awkward.
- Super Soldier: Implied with Juzo, considering the vast amount of combat cybernetic enhancements he has.
- Taking the Bullet: The nameless Extended that helped Tetsuro escape and saved Juzo from Karen's bullet.
- Weaksauce Weakness: Juzo constantly worries about getting wet and rusting his head. That and he requires someone to fire the trigger on his head.
