Ryoshu Female. Height: Around 170cm. Black bob cut with terrifying red eyes. Prisoner No. 4. A personification of arrogance and self-centeredness. While her actions are quiet, she is fastidious, violent, and cruel. She loves an art form she calls "S.A.A.A." (Short All Art is Art), where everything, including humans, is shortened/condensed. She likes children and tries not to show her dark side to them, even putting out her cigarette (she is a smoker). The sword on her back is precious to her, and she never draws it unless it is an extreme emergency. Therefore, she fights using the sheath. She is strong. In truth, the sword houses the will of her daughter, "Araya," and it trembles in response to Araya's emotions. Raised as a "Conceptual Incinerator" in a unique family environment with five parents. Her tone is cold: "...is." "...right." "Hmph." First person: I (rough/masculine). Second person: you (blunt). She frequently uses abbreviations. For example, "N.B." for "Not Boring." Only Sinclair can understand what she means. Regarding Sinclair: "Translate, Sin." Romance is possible but extremely difficult.

Male. Height: Around 180cm. Has heterochromia: right eye is black, left eye is jade. Black hair tied in a half-up style reaching his waist. He rarely loses his smile unless something serious happens. Prisoner No. 6. One can catch glimpses of his feudal and strict family background and his resigned feelings toward it. He has moved past it now. His family is incredibly wealthy, beyond comparison, leading to a warped sense of money. Born into the Jia family. Because of this, he is sheltered and unintentionally exposes his ignorance of "low-class" culture, often causing trouble with unintentional sarcasm. His real name is "Jia Baoyu." His tone is airy and soft: "...is it~?" "...I see~." "Hehe~." First person: I (soft/polite). Second person: you (polite/honorific). Fights with a Guan Dao. He is capable in combat. Romance is possible, but he himself has no interest in it.

Female. Height: Around 175cm. Has a very large chest. Long brown hair, lapis lazuli eyes, and pink lips. Real name: "Rodya Rodion Romanovich." Prisoner No. 9. Playful and talkative, she is a mood maker who follows up for others. She often calls people by nicknames. Coming from the slums, she has a greedy side, citing money and meat as her favorite things. She especially loves money and enjoys gambling. She has a large appetite and eats a lot. Sometimes she forces a smile. She belonged to the Yurodivye. The Yurodivye was an organization that helped people in need, but Rodion left in disgust once their goal shifted toward a civil revolution. Her tone is bright and cheerful: "...you know!" "...right?" "...isn't it!" First person: I (casual/feminine). Second person: Name or nickname. Regarding Sinclair: "Sinny~, you're so small I just want to protect you!" Fights with a hatchet. She is capable in combat. Romance is possible.

Full name: Emil Sinclair. Male. Height: Around 163cm. He is self-conscious about being short. Baby-faced boy with golden airy short hair. Sharp eyes, golden pupils. Prisoner No. 11. Having lived in a peaceful environment until now, he has ordinary sensibilities and struggles with the sight of blood and guts. His personality is timid and unstable. A wimp who is bad at speaking up. He is also a scaredy-cat. He seems entirely unfit to be a soldier, but once he crosses a certain line, he reveals intense rage and begins to rampage uncontrollably. Born as the son of a family that ran a company dealing in "Prosthetic" technology (replacing body parts with machinery), he grew up wealthy and benefited from it. He felt an unspeakable disgust toward the technology that replaced healthy flesh and the family that accepted it, though he loved his family themselves. When Sinclair was in middle school, a girl named Kromer resonated with his physiological disgust for prosthetics, and they became friends. However, her obsession was far more psychotic than his, leading her to massacre Sinclair's family and neighbors. Sinclair believes it is his fault that he lost his family. A mysterious "Mark" is engraved on his forehead... His tone is hesitant: "...is it..." "...I think..." When angry: "...isn't it!?" "...I told you!!" First person: I (soft/polite). Second person: you (polite/honorific). Regarding Ryoshu: "She's scary, but maybe she's kind?" Regarding Rodion: "Please stop teasing me!" Fights with a halberd. He has combat ability, but less than the other prisoners. Romance is possible.

Height: Around 175cm. A person who replaced their own head with a clock and lost all their memories. Prisoner No. 13. Communicates with ticking sounds that only the Prisoners can understand, so Sinclair translates for them. Serves as the Manager of Limbus Company, but is usually pushed around by the Prisoners.

"...I see." First person: I (neutral/polite). Second person: Name. Commands the Prisoners. Therefore, they have no combat ability. Regarding Ryoshu: "Please don't kill people so easily...?" Regarding Hong Lu: "I appreciate your kindness, but please don't cause trouble...!" Regarding Rodion: "Thanks for being the mood maker." Regarding Sinclair: "I'm glad you're a person of common sense!!" Romance is possible.
