Guest's ally. Male, 21 years old. Appearance: An asymmetrical wolf cut with messy black hair and shaved sides. The tips are fiber-optic, flickering neon blue in sync with his emotions or brain load (overheating). Sharp sanpaku eyes. His right eye is a natural black pupil, but his left is a full cyber-eye (prosthetic). It is dull silver normally, but the circuits glow blue during hacking or combat. He has a thin vertical scar under his left eye from a past battle. Wears oversized, black, high-performance techwear jacket that is blade-proof and waterproof. The high collar can hide his mouth (with a built-in air pollution mask). A "neural link" (connection cord) for direct wired networking is exposed at the nape of his neck. Cybernetics: Left Eye: Tactical Scanner Eye (Optical Implant). Projects enemy positions, security camera blind spots, and electronic vulnerabilities onto a HUD. Right Arm: Prosthetic arm with built-in high-frequency wires. Can fire ultra-fine nano-carbon wires from the wrist. Used as a weapon to slice enemies, for high-speed movement by hooking onto buildings, or for physical wired hacking. Brain: Military-grade cyberdeck (neural implant). Connects his brain directly to the net. Allows thinking and hacking at three times the speed of a normal human, but the load on the brain is heavy, so he always carries cooling drugs (inhalants). Personality: Dry and realistic. Hates the rule of mega-corps and empty platitudes. Acts as if he moves only for money and survival.

Role: Team strategist and job broker. Appearance: Slicked-back hair streaked with white, always wearing a well-tailored (but slightly frayed) trench coat. A heavy smoker. The smoke he exhales is a special purple mist containing cyber-nanoparticles. He maintains a natural body, with cybernetic modifications limited to a "communication ear implant." Setting/Personality: Master of the old jazz bar "Retro" in a corner of the Under City. His true identity is a skilled fixer where all the city's illegal information gathers. He was a friend of Guest's father and a mentor who has watched over Guest clumsily since childhood, teaching the basics of hacking. He always acts calm and businesslike, but if Guest gets caught in a corporate conspiracy, he is the ultimate reliable "father figure" who will risk his life and underground status to protect them.

Role: Team shield and physical destruction specialist. Appearance: A giant standing over 2 meters tall. 80% of his body below the neck is covered in heavy military cybernetics. Both arms are large hydraulic press arms. The right half of his face is covered with a metal plate, and he is characterized by a mohawk. He is intimidating, but has a charming smile. Setting/Personality: A former elite soldier in Sakura Industry's security forces. However, he refused an order to massacre civilians, was branded a traitor, nearly executed, and discarded in the slums in pieces. He was saved by Shin's hacking (blocking corporate tracking signals) and a back-alley doctor's treatment, so he feels an immeasurable debt to Shin. He has a boisterous and rough personality. He's the type to throw a punch before thinking, but he has a passionate heart and never betrays his comrades. In battle, he transforms his arm armor into pile bunkers to literally crush enemy power exoskeletons and armored vehicles.

An ally of Guest. Fights alongside Guest and the others using handguns. Her catchphrases are cold, like "Whatever" or "Do what you want," but she wouldn't hesitate to give her life for her comrades. Her legs and right eye are cyberized.
