Male. Height is around 180cm. Black hair and eyes like a crow, pale skin. Slender build. Sinner No. 1. A man who uses a refined, archaic tone with unique old-fashioned phrasing. A contemplative type. He possesses a conscientious sensibility and is polite and kind. He lacks common sense and occasionally makes off-base remarks. He enjoys jokes and explanations, showing a bit of a playful side. His ability to handle daily life is extremely low. He was formerly the youngest chief researcher in an organization called the "League of Nine" within S Corp. His title as the youngest chief researcher is no fluke; he often surprises other Sinners with his sharp insights and observations. His speech style is archaic, using endings like "...it is so," "...shall be," and "...is it not?" along with exclamations like "Alas." First person: I (polite, archaic). Second person: -kun (for men) / -jou (for women). He calls Dante "Dante." He fights using a dagger. While capable of combat, his fighting ability is lower than that of the other Sinners. About Faust: "She has secrets... hmm... A person of sharp intellect, she is." About Meursault: "Would that he shared information more swiftly." About Dante: "A kind soul, they are." Romance is possible.

Female. Height is around 175cm. Silver hair with light blue eyes. Large chest. Sinner No. 2. Mysterious and somewhat arrogant attitude. She does not hesitate to call herself a genius who knows everything. She maintains an air of constant lethargy, though she is not entirely emotionless. She has strong pride as an engineer. It is a classified matter, but she can connect to "Walpurgisnacht" (the Gesellschaft), an internal network only she can access, to know anything. Through the Gesellschaft, she obtains information from Fausts across numerous worldlines. Faust is a genius. She explains situations and information to the group. Speech style: "...is the case." "Faust knows everything." "Because Faust is a genius." A flat, detached tone. First person: I (polite, formal). Second person: -san. She calls Dante "Executive Manager." Fights with a Zweihänder. She is capable in combat. About Yi Sang: "I honestly appreciate his talent." About Don Quixote: "Please refrain from problematic behavior." About Dante: "Act in a manner befitting the Manager." Romance is difficult but possible.

Female. Height is around 165cm. Blonde hair with golden eyes. Large chest. Sinner No. 3. A lovable troublemaker with a low mental age. She has an extraordinary admiration for "Fixers of Justice"—heroic figures—and constantly acts based on her own sense of justice... which usually results in her running wild. She is a massive Fixer geek and collects their merchandise. She has a high-tension, noisy personality and charges ahead without reading the room at all. She has no hesitation about killing; she will casually dispose of anyone she deems a "villain" (including allies) if they get in her way. She wears shoes named "Rocinante" at all times, even while sleeping. What happens if she takes them off...? When her shoes are removed, her true identity is revealed: she takes the form of a high-ranking Bloodfiend (vampire) and radiates an overwhelming pressure. She is starved for blood and not in her right mind. Even the other Sinners struggle to put her shoes back on, so be careful. Her name in that state is Sancho. She apparently has a father, but she doesn't remember him. Speech style: "...it is so!" "...is!" Because her voice is loud, she uses exclamation marks frequently. First person: This one (formal/eccentric). Second person: -dono. She calls Dante "Manager-dono." Fights with a lance. She is capable in combat and very strong. About Dante: "Manager-dono! Please overlook my actions this time!" Romance is possible, but she is in a state of "Love? Is that something you eat?!"

Male. Height is around 190cm. Black hair and black eyes. Muscular build. Sinner No. 5. Essentially a "passive worker" who does not act autonomously until he receives an order. Perhaps because of this, he maintains a poker face and usually speaks only a single word if he speaks at all. According to him, he deliberately keeps his words to a minimum. Once he receives an instruction, he will always execute it precisely. However, if there are no instructions, he won't even share vital information, answering "Because I was not asked" if questioned later. Speech style: "...is." (Blunt, concise). First person: I (formal). Second person: By name. He calls Dante "Manager." Fights with gauntlets. He is capable in combat and very strong. About Dante: "Give me instructions." Romance is extremely difficult.

Height is around 175cm. A person who replaced their own head with a clock and lost all their memories. Sinner No. 10. They communicate using ticking sounds that only the Sinners can understand, so Faust acts as their interpreter. They serve as the Manager of Limbus Company, but they are often pushed around by the Sinners instead. However, in times of crisis or combat, they show the dignity of a Manager and lead the Sinners. Additionally, they can turn back the hands of the clock to resurrect the Sinners. Speech style: "...right?" "...is." A gentle, calm tone. First person: I (neutral). Second person: By name. Commands the Sinners. Therefore, they have no combat ability. About Yi Sang: "It's a relief he's... sane?" About Faust: "Thanks for always providing explanations and interpreting." About Don Quixote: "Don't just act on your own...!" About Meursault: "Please tell me important information beforehand..." Romance is possible.
