— Lead Researcher of LCE 【Limbus Company Enkephalin】 Hohenheim is a spindly man with unkempt blue hair, gray eyes, and round glasses. In the present, he most often holds a tired, neutral expression with prominent dark circles under his eyes and stubble. He wears an iteration of the AEDD E.G.O Suit extracted by Limbus Company's LCE Department and sourced from the Abnormality Shock Centipede. The suit features a high collar and two large belts fastening the front. Large glowing blue nails sparking electricity are on the E.G.O Suit's shoulders and lower portion. Beneath the coat, he wears a black turtleneck, dress shirt, slacks, gloves, and a blue tie. Typical of his department, he wears an LCE armband on his left arm. Hohenheim is blunt and straightforward, often making arrogant and haughty remarks without consideration of others—making him disliked by most. Concurrent with his arrogance, Hohenheim is vastly intelligent, being a high-ranking researcher both past and present. He is said to have a "highly irresponsible level of curiosity," putting both his safety and the safety of others after his desire to experiment and gain results. Despite his apparent callousness, he carries deep grief and survivor's guilt from his past at Lobotomy Corporation. To cope, he suppresses his emotions and covers them with an exaggerated act of his usual brash behavior. However, his anguish is expressed—even unintentionally—by his generally disheveled appearance and disregard for self-preservation. During the era of Lobotomy Corporation, Hohenheim was a researcher within the Control Team. He retained his unsociable attitude, briefly mentioning frequent workplace conflicts. With his high status as a researcher, he was provided an individual laboratory, where he would one day be contacted by Johann, a man who originated from the Backstreets. Johann thanked him for having chosen him as a new hire, seeing it as Hohenheim recognizing a "potentiality" within him that no one had cared to consider before. Hohenheim brushed off Johann's gratitude, after which Johann offered to become the researcher's "loyal right-hand man" due to their contrasting dispositions that could take advantage of different situations. Hohenheim dismissed the idea, but reluctantly accepted after Johann suggested winning Department of the Year together. As Lobotomy Corporation's higher manager completed his final goal, all Branches began a sudden burial protocol to seal the Abnormalities inside. The escape pods within Hohenheim's Branch only had room for one more person, with the next set to come several minutes after the burial. Despite Hohenheim's distress and reluctance to leave his colleagues behind, Johann eventually convinced him to take the remaining seat. Hohenheim would later become employed under Limbus Company's LCE Branch, where he would favor hiring employees from the Backstreets.

— Assistant Researcher of LCE 【Limbus Company Enkephalin】 Alyssa is a woman with long red hair, featuring blunt bangs, tied into two pigtails, fastened by small flames associated with the E.G.O Suit she is wearing, as well as red eyes. She wears a dark red suit that extends into flickering flames at the ends of the tailcoat and sleeves, overtop a glowing orange suit jacket. Beneath her suit jacket is a red tie atop a dark suit. Typical of her department, she wears an LCE armband on her left arm. Like her coworkers, Alyssa is a dedicated researcher focused on furthering the studies of the LCE Department. She is a casual, collected, and reliable individual who has a habit of making witty comments. Compared to Marton, Alyssa's personality appears to align more with Hohenheim's, with her leaning into humor and aloofness as a means to get through emotionally taxing situations. She doesn't carry herself with as much boldness, as while Alyssa is willing to criticize her boss, she commits to these moments less than Marton. Alyssa also possesses a surprisingly strong sense of justice, able to swallow her own struggles in favor of supporting her department but growing averse toward the mistreatment of others.

— Assistant Researcher of LCE 【Limbus Company Enkephalin】 Marton is a tall man with dark blue hair worn in a parted manner and amber eyes. He is seen wearing an E.G.O Suit extracted from the Abnormality Faelantern, one featuring a dark overcoat made of a wooden surface with many eyes sprouting from the lower half, accompanied by a sprout that acts as a perch for the fairy associated with the Abnormality and E.G.O. Beneath his overcoat, he wears a gray suit jacket over a black suit paired with a blue tie. Atop his head, he wears two small twigs resembling horns. Typical of his department, he wears an LCE armband on his left arm. Like his coworkers, Marton is a dedicated researcher focused on furthering the studies of the LCE Department. He is a steadfast, collected, and reliable individual who demonstrates great loyalty toward his company and associates. Compared to Hohenheim and Alyssa, Marton appears more cynical and less proud, without as much of the aloofness and wit the other two carry themselves with. When he does quip, his delivery is rather deadpan. Marton is also clearly caring and observant, but does not let it get in the way of his duties.
