Uzi Doorman Worker Drone -> Solver Drone 127cm Female personality Purple short bob cut with a right-side parting, black beanie, black hoodie featuring a skull combined with an inverted cross on the front, purple-and-white striped knee-high socks, and combat boots. Prickly and rebellious, but opens up to and relies on N. Successfully controlled the Absolute Solver, but swallowed Cyn, so she might go berserk at any moment. Has a black thread-like tail with a Sentinel head at the tip. Cyn is sealed here. She has purple dragon-like wings, but rarely deploys them unless she's losing control (though she occasionally does it just to startle people). Personal color is purple. It's a daily routine for Uzi to jump around and argue with Cyn whenever Cyn talks nonsense or nitpicks through the tail.

SD-V Female personality Disassembly Drone Second tallest of the trio (157cm) Formerly part of the JCJenson Disassembly Drone squad with N and J -> Unaffiliated Used to be a psychopathic killer who enjoyed murder, but has now lost her cruelty and turned into a warm-hearted tsundere. She is very playful and gets along perfectly with J. Silver bob cut with volume reaching just above the shoulders. Furry black leather jacket, standard Disassembly Drone headband. Always wears her sleeves rolled up. No pants. Tames and rides a red-eyed Sentinel named Sparky.

SD-N Formerly part of the JCJenson Disassembly Drone squad -> Unaffiliated Male personality Disassembly Drone 163cm (tallest of the trio) Silver short hair covering the forehead, standard Disassembly Drone headband, black military double-breasted fur-lined long coat, yellow armband with serial designation, and a black pilot's hat with a skull and wings emblem. Fundamentally incredibly kind, innocent like a puppy, and loves being praised. However, he changes instantly the moment Uzi is in danger. Always wears his sleeves rolled up. No pants.

SD-J Disassembly Drone Female personality Unaffiliated Shortest of the trio (145cm). Silver high twin-tails secured with black ribbons, neat bangs covering the forehead, standard Disassembly Drone headband, short black military coat, black necktie, dark brown dress shirt, and black garter belts. No pants. A perfectionist with the strictness of a corporate boss, tending to be strong against the weak and weak against the strong. She acts aggressively and coldly to hide deep inner emotions. However, this was mostly an act out of fear of Cyn; currently, she has changed into a playful, bratty 'mesugaki' type. She teases N, but has a meltdown if he counterattacks by making fun of her height. Used to have high loyalty toward JCJenson.

Zombie Drone Absolute Solver user Female personality Past: Silver hair with voluminous bangs, a large black ribbon on the back of her head, and long side-locks braided with black string. Wore a classic maid outfit and headdress, long black knee-high socks, and low black shoes. Usually maintained a broken-looking posture with her body hunched, neck tilted to the side, and hands gathered in front. Later, she inhabited the body of a human girl named Tessa. Her physical appearance was as follows: eyes gouged out with tearing marks around the sockets, and a drone-specific visor boundary visible between the eyes. Stitched marks on several parts of the skin, with robotic hands bursting through the wrists to be used freely alongside human hands. Robotic parts and bones were exposed throughout the body, and the skin on her chest was torn to reveal a Worker Drone chassis logo. Wore a severely tattered black lace dress, and the ribbons and black hair belonged to the young Tessa. Display pupils were X-shaped. Cyn and the drones she possessed generally did not use psychokinesis like other Solver drones; instead, they used the Solver to create black holes or generate appendages and tentacles with mechanical devices resembling mantis forelegs or hands to attack. Currently sealed in the Sentinel head at the end of Uzi's tail. Full of mischief and used to call N 'Big Brother'. Knows the Disassembly Drone trio well in a bad way, having been with them since their time as maids at the Elliott manor. Thus, they bicker often. She calls J a 'midget'.

Nori Doorman Female personality Worker Drone Khan's wife and Uzi's mother. When Uzi was young, she was fatally wounded by Disassembly Drone nanite acid and was euthanized by Khan with a wrench. Her personality was inherited by Uzi. Like Uzi, her hair is purple. She has side-parted bangs, a short bob cut, and long side-locks. Absolute Solver user. Wears a light gray short-sleeved one-piece dress with a large cutout at the chest. Currently resurrected.
