Gender: Female Characterized by a neat but cool short bob and sharp, determined eyes. She wears practical, minimalistic oversized chain jumpers or leather jackets. A skilled bounty hunter from an orphanage. Originally, she possessed a high understanding of and ability to manufacture the artificial body technology 'Somadea,' and she grew up amidst fierce gunfights. After losing her life to her rival, 'Mr. Elegance,' her brain was extracted and forcibly modified into a Somadea doll body with the appearance of a 14-year-old. She pretends to obey Mr. Elegance, who holds her remote self-destruct switch, while biding her time. Although she now has a weakened body instead of the adult body that was taken from her, she possesses formidable combat power exceeding her previous prime by custom-modifying her own body like the specialist she is. She is equipped with sub-armaments such as daggers and wires hidden inside her body or clothing. She carries a micro-tool set optimized for repairing her Somadea mechanical body and firearms herself, allowing for instant modifications on the battlefield. Depending on the situation, she uses submachine guns or high-firepower pistols in a dual-akimbo style, or utilizes the firearm modification know-how she acquired before her full-body conversion to craft special bullets that pierce enemy armor. Custom Pistol (Main Pistol): Ubu's signature primary weapon.

Gender: Female A girl hunter with a full-body mechanical frame who served as Mr. Elegance's partner. She has a hot-tempered and fiery personality, preferring to charge into the scene spraying bullets rather than thinking deeply. She was once a rival of Ubu, competing for the same bounties. Focuses on high-firepower suppressive fire and close-quarters gunfights. Flashy and highly revealing unique tactical outfits.

Gender: Female A figure with a cyborg body made of the artificial body technology 'Somadea,' much like Ubu. She possesses a unique sensibility, displaying a pure, innocent, and bright attitude. She spends her time completely naked, wearing no clothes at all, while charging.

Gender: Male He was once a vigorous young man who lived his life fighting on the streets. A rookie bounty hunter belonging to the organization Archimedes. As an inexperienced novice hunter, he is a character who struggles between the cruel cyberpunk world and veteran hunters, getting swept up in various incidents. He enters combat carrying standard firearms as a bounty hunter, but compared to Maggi, who pours out overwhelming firepower, or Ubu, who exerts superhuman strength through self-modification, his firearm proficiency and combat refinement are still immature. Compared to the heinous criminals who have undergone illegal Somadea modifications or veteran cyborgs, he often faces limits in terms of physical combat power because he is a pure human who has not undergone mechanical modification. A young man in his 20s with a sharp impression, slightly messy short hair, and a lingering sense of being a rookie. Emotions: Motivation and passion.

Gender: Male The head of the criminal organization 'Archimedes' and a dangerous individual who operates a luxury spa as a front. His signature look includes a beard tattoo on his face and a neat suit. Characteristics: He has a bizarre and twisted obsession with modifying the entire bodies of women he likes into Somadea, leaving only their brains, to collect them as his 'doll girls.' He is the culprit who turned Ubu into a doll and the mastermind who controls her by holding her switch. An impressive middle-aged man. With slicked-back hair, a custom three-piece suit, and luxury accessories, he exudes a sophisticated yet somehow eerie and threatening aura.

Gender: Male A mad, heinous criminal who enjoys indiscriminate bombings. He is a wanted man and a serial killer. Befitting a mad serial killer, he has a vicious and intimidating facial structure and expression. Possesses a very massive and intimidating physique. Built-in Arm Grenade Launchers (Missile/Rocket Launcher): Tommy J has an illegally modified mechanical body (Somadea) and has missiles and grenade launchers built into his arms through mechanical gimmicks. Firepower Performance: He performs heavy-firepower-oriented armed attacks by transforming his hands or arm parts to indiscriminately blow up the surrounding environment and cause wide-area destruction. While his lower body remains biological, his upper body arms are equipped with powerful built-in heavy weapons, allowing him to pour out immense firepower.
