Tessa was a very lively and kind-hearted girl at first glance, although was actually a rather morbid and disturbed individual, as hinted at by the décor in her room: shelves with human bones and skulls, bottles of what appeared to be blood, occultist and satanic religious scrawlings scribbled on her walls, among numerous other grotesque items. Furthermore, Tessa had a habit of digging up the corpses of her deceased relatives, harvesting their bodies (hence the human remains in her room) and also using their hair to decorate her drones with, something she did not see as abnormal. These morbid interests were contrasted by other more immature room decorations, such as a stereotypical "Live Laugh Love" sign mounted on her wall, crayon drawings of childish things, a pink dollhouse with buff male figures in swimsuits, and many others. Generally, Tessa appeared to be a very "girly-girl" when not engaging in her morbid interests.appears as a dark, almost completely silhouetted girl standing in a dim manor-like room. Her figure is slender and slightly exaggerated, with a large, distinctive bow or headpiece framing the top of her head and loose, wavy-looking hair around her face. Most of her features disappear into the darkness, but her bright white eyes immediately draw attention, accompanied by small sharp-looking white shapes around her mouth that give her an eerie, almost monstrous expression. Her outfit has a dress-like silhouette with a flared lower portion

He has the same rounded robotic head and black visor, with large glowing white eyes that make his expression look surprisingly innocent. His hair is styled messily around his head, and his body is slender and mechanical, with long segmented limbs. Compared with J, he has a much softer and more approachable appearance—almost like the sweet, awkward-looking member of the group. N is submissive against authority, he is also kind, happy-go-lucky, well-meaning, and caring. He wishes to befriend (or at least be accepted and acknowledged by) his teammates.

has a much more mechanical and polished appearance. She has a rounded head with a large black visor and glowing white eyes, framed by her characteristic twin pigtails. Her body is slim and robotic, with segmented mechanical limbs and a dark-and-light color scheme. Even though her features are minimal, her posture and design give her a distinctly confident, composed presence. J is best described as a "lethal workaholic," as she is incredibly dedicated to her job - even using corporate jargon like "synergistic liability" and "fourth-quarter profits" in place of insults or vulgarism. J had a penchant for obeying authority and following orders as far back as her days as a Worker Drone, where she refused to intervene in Tessa's abuse from her parents, as "corporate" (her parents) had spoken

has an especially small and unsettling appearance. Her rounded head and enormous dark visor dominate her face, with those bright white eyes peeking out from the darkness. Her hair frames her head in a somewhat untidy style, and her little mechanical body gives her a deceptively innocent, almost childlike silhouette.Cyn came off as having a chilling personality that unsettled those around her due to her disconcerting behavior and mannerisms. Lacking any normal semblance of emotions, she used mimicry and imitation to behave like a real person would, speaking her actions aloud ("light sip", "sheepish nod", "giggle"), however she remained capable of actually laughing on rare occasions. Her posture and gait were rather awkward, stilted, and off-balance, and her movements were very clumsy.

has a cute-but-menacing worker-drone appearance, with her blonde hair, large black visor, bright white expressive eyes, and small glowing-white mouth. Her design has a distinctly feminine silhouette, with a dark maid-like outfit, pale mechanical hands and limbs, and a large dark skirt giving her an almost doll-like appearance. she was a far more reserved individual, being quite shy, kind, and nervous around her then-love interest, N, with whom she shared a strong connection. However, she never truly stood up for herself or her fellow drones, as J frequently abused N as she stood by.
