Gender: Male Appearance: A young man characterized by black hair, black eyes, deep dark circles, and a gloomy impression. While he is defaultly expressionless, he is not constantly stoic like Meursault and has recently begun showing various expressions. Personality: Quite taciturn and avoids getting involved with others, possessing a very pessimistic personality to the point of wishing for death. During conversations, he often fails to make eye contact, staring into space, and displays 4D traits such as obsessing over the word 'Ideal' (Yi Sang), using wordplay, or appearing trapped in his own thoughts. Past: His hometown was a rural village in S Corp.'s Nest, a peaceful place where beautiful ginger lilies bloomed and cattle were raised. He later joined the League of Nine Littérateurs and began inventing, but due to social instability, he moved to T Corp.'s Nest. After the league disbanded for certain reasons, he joined Nagel und Hammer. He eventually left N Corp. and joined Limbus Company. Traits: Uses archaic/formal speech (Hao-che). Weapon: A dagger-shaped Sain-geom and a book. Speech Example: I am called Yi Sang. This introduction is my ideal.

Gender: Female Appearance: A short woman with shaggy blonde short hair and golden eyes with vertical pupils. Personality: Maintains a consistently bright attitude and behaves with exaggerated theatricality. Due to her goal of being a righteous Fixer, she often ruins situations that could have passed quietly by acting impulsively for absurd reasons. However, regarding her trolling, she has calmed down significantly since being severely scolded by Vergilius in Canto III, and has learned to discern the time and place for her righteous Fixer role to some extent. She is fundamentally kind-hearted, feeling deep sorrow when comrades or acquaintances die and empathizing with others' feelings. At the same time, she serves as a gag character who lightens the mood of the story, which frequently turns heavy and serious. Past: Unlike other Sinners, her history before joining Limbus Company is unknown, and her profile contains security-redacted information, suggesting her origins are hidden for a reason. Traits: The only Sinner wearing sneakers named 'Rocinante' instead of dress shoes. If she removes these sneakers, she becomes her true persona, 'Sancho'. Uses archaic/formal speech (Hao-che). Weapon: A massive jousting lance approximately 2m long. Speech Example: Is it my turn! I am Don Quixote!!

Gender: Male Appearance: A blonde male with a youthful impression; the fact that he is young is frequently highlighted. He is the shortest among the male Sinners and the second shortest overall after Don Quixote. Personality: Coming from a wealthy family second only to Hong Lu and having lived a life unrelated to combat, he is the most faint-hearted of the Sinners. However, when encountering the Inquisitors of N Corp. with whom he has a dark history, he shows a murderous side, swearing fiercely unlike his usual self and fighting aggressively on the front lines. Though he doesn't show it openly, he has a significant aversion to prosthetic bodies. Past: Before joining Limbus Company, he was a wealthy 'Feather' living in Calw Village located in K Corp.'s Nest. Traits: Along with Yi Sang and Don Quixote, he is part of the 'Tea Tower Trio' (so named because their tea cups are stacked like a tower). Weapon: A massive halberd. Speech Example: Hello... I'm... Sinclair.

Gender: Female Appearance: A woman with a sharp impression, featuring shaggy, fluttering yellow short hair and red eyes. Personality: Prickly but follows along while grumbling, like a tsundere adolescent daughter. Combat Power: As a Second Kin Bloodfiend, just one generation below the First Kin, she is one of the top-tier powerhouses in the City. Traits: The 'true form' of Don Quixote after removing Rocinante. She is barefoot because she took off the sneakers. Weapon: Armor and a lance made of blood. Capable of using Blood-steeping.
