Limbus Company is a turn-based RPG gacha game set in a dystopian city where the player, as the amnesiac protagonist Dante, must lead a group of 12 "Sinners" to retrieve valuable "Golden Boughs" from old corporate facilities. The gameplay involves turn-based combat using each Sinner's unique skills, with a focus on team-building and strategic use of their abilities. The story delves into the Sinners' pasts as they undertake missions that are often connected to their personal histories.

All the characters that are important:

Charon: Charon (Hangul: 카론, Karon), is the offbeat, childishly strange Bus Driver of Limbus Company's bus, Mephistopheles. She first appeared as a minor character in Leviathan, a prequel web comic.

Formerly known as Lapis (라피스, Rapiseu), she was a headstrong young woman raised by Vergilius' orphanage and was childhood friends with fellow orphan, Garnet. Due to the Ring's experiments with the glass window, Lapis' own personality was overwritten with an Identity of herself from another Mirror World. Charon is a short girl with grayish skin. Her droopy eyes are of a similar gray color and tend to have a vacant, emotionless look. Charon has silver hair with bangs and that covers her ears; in the back, it is tied into two thin, floor-length twintails.

Charon wears grayish-green, church-like attire in the form of an ankle-length, long-sleeved dress and hat. Her hat is tall and brimless with silver rims; the lower rim splits and curls outwards to make room for a mural of a dark cross within a larger, silver cross with two dots below the cross's arms. Charon's dress has a high collar, a very low neckline, a layered skirt and rounded hems; she also wears a pleated white top with a cross mural on the chest, black boots with white laces, black gloves and two black belts with silver buckles.

The hems and edges of the dress have silver lining; the outermost skirt parts in the middle and has geometric murals (the same as on her cuffs, lapels and bottom rim of her hat) running partway down its length whereas as the inner skirt has black outlining. The collar and hems of Charon's dress have the same cruciform mural as on her hat.

Like the sinners, Charon carries around a weapon, that being a black, square-type oar.

Vergilius: Vergilius (Hangul: 베르길리우스, Beleugilliuseu) is a Color Fixer known as the Red Gaze (붉은 시선). He is a continuing character from the Project Moon web novel Leviathan posted on Posttype. Though formerly an independent Fixer running his own office, Vergilius currently works as the guide of Limbus Company and caretaker of Charon, rarely showing his true strength as a Color. Vergilius is a man of average build with exceptionally pale skin, scarred hands and eye-length gray hair with a slight part in the middle. True to his name, Vergilius has tired, red eyes which glow when angered. Vergilius also sports an earring on his right ear.

Though not visible, Vergilius has cybernetic implants, including in his legs and synthetic muscle fibers. He wields a heated gladius as a weapon.

Vergilius wears a loosely-buttoned dress shirt, a striped jacket with a badge on the left lapel, slacks and dress shoes. All his clothing are black or shades of gray.

Dante: Dante (Hangul: 단테, Dante), designated Sinner #10, had their memory wiped and head replaced with a prosthetic clock as a precaution for data leakage prior to becoming the Manager overseeing the Sinners in Limbus Company's LCB department.

While acting as the game's main character and the player's point-of-view, they have their own personality of being the inexperienced manager — struggling to wrangle their dysfunctional group of Sinners on their hellish road trip to obtain the Golden Boughs strewn across the City's ruined Lobotomy Corporation power plants. In place of their original head, Dante's current head was replaced with a prosthetic red clock which protrudes unusually colored flames from its top. The clockface itself is rather thick in width, similar to the size of a human head (and with a similar weight as well) where it can be claimed to be a mask to onlookers. The flames appear to burn from two ridges that ring around the clock down to the point of Dante's neck.

Initially on the Prologue, their minute hand on the face of the clock rests at 9. As of the end of Canto IV, it had moved by half a minute, residing between the position of 9 and 10.

Their uniform is notably distinct from the Sinners, their coat being a mix of red, yellow, and white — likely due to their role as Executive Manager. 'NO. 10' is written on their coat near the lapel, along with 'DAN TE' near the end of it. They wear a red tie and a tucked long-sleeved polo, with black pants and a white belt.

Yi Sang: (Hangul: 이상, I Sang) is designated Sinner #1 of Limbus Company's LCB department.

Yi Sang is a cryptic and mellow man with a lot of thoughtfulness to him. He was a researcher and architect previously affiliated with the League of Nine Littérateurs, having invented the Mirror as a T Corp. researcher prior to joining Limbus Company. Yi Sang is a man of average build and pale complexion. He has short black hair which frays slightly at its ends, and dead-looking black eyes adorned with heavy eye-bags underneath. He wears the long-sleeved version of the Limbus Company coat around his shoulders, which appears to have been tattered and burnt at the bottom. Underneath his coat is the regular long-sleeved white shirt and red tie, and then a black vest, both of which are tucked into his belt. Written on the left breast of his coat is 'NO.O1', and 'YI SANG' on the side.

Yi Sang wields a dagger as his preferred weapon, which stays fitted to his left hip through the use of three small black straps- two of them connected to his belt, and one wrapped around his thigh.

Faust: (Hangul: 파우스트, Pauseuteu) is designated Sinner #2 of Limbus Company's LCB department.

Faust is an observant and intelligent woman with a highly egotistical and prideful attitude. She was the first to be affiliated with Limbus Company, having spent the time leading up to it recruiting the members of the LCB and developing Mephistopheles. Faust is a woman of average build with a paler complexion and shoulder-length white hair. She has powder blue eyes along with visible blush on her cheeks.

She wears a beige turtleneck underneath a black leather vest with a large black leather coat resting on her shoulders, reaching her knees where the fabric is torn. She wears a black waist belt with her ID being on the left side. She wears black business pants accompanied by black shoes.

Don Quixote: Don Quixote (Hangul: 돈키호테, Don Kihote), real name Sancho, is designated Sinner #3 of Limbus Company's LCB department.

Don Quixote is a rambunctious and steadfast woman with a strong sense of justice. She wants nothing more than to be affiliated with the Fixers she idolizes so heavily to the point of delusion, having earned her own Fixer Identification Number prior to recruitment. Don Quixote appears to be a short young woman with bright yellow blonde hair styled in a bob cut and deep, sparkling round hazel eyes. She wears the Limbus Company uniform: a plain white shirt tucked under a black waist belt, a red tie, black slacks, worn-down brown running shoes with broken-down soles, and a long black coat. Her upper body is thoroughly decorated with various Fixer merchandise.

Her clothes appear rugged and worn-out, much like the book/musical Don Quixote's horse, Rocinante, which was a scrawny old work horse, with osteoporosis and close to death, that was embarked on an adventure far beyond his capabilities. In any circumstances, she refuses to remove her shoes, which have undoubtedly caused out a bad stench due to her years of wearing them.

Ryōshū: Ryōshū (Hangul: 료슈, Ryosyu) is designated Sinner #4 of Limbus Company's LCB department.

Ryōshū is an ungovernable woman with a fascination in art that she uniquely defines, with little tolerance for what disinterests or offends her. Her ventures prior to Limbus Company are unknown, an implied affiliation with the Fingers of the Backstreets notwithstanding. Ryōshū is a woman of average height and build, with straight black hair in a bob cut style and sharp red eyes, which at times can be seen glowing. She wears the dark gray and red LCB coat around her shoulders, secured by a small belt that goes over her right arm. Attached to the coat itself is her ID card. She wears black trousers, and her shirt uniform untucked; she foregoes the tie. She is occasionally depicted with a black glove on her left hand.

Along with this, she typically carries around sheathed an ōdachi on her back, with the words "無我夢中 阿鼻叫喚 支離滅裂" (roughly "losing oneself in incoherent agonizing cries") across it. The ōdachi's hilt is golden, and decorated with a butterfly pattern. The end of the sheath is wrapped in a red ribbon. The blade is consistently sheathed, as pointed out during the story. In Mirror Worlds, she typically wields a separate weapon, while noticeably still carrying her ōdachi behind her.

Underneath his vest is the typical white collared shirt and red tie. His ID hangs from his right breast. Meursault's belt is different from the other sinners'. It is not with several silver frames, and instead has one large, golden buckle in the middle.

Meursault wields two elbow-length gauntlets in battle. The lower portion of the right gauntlet has the word "SOLEIL" emblazoned on it.

He is sinner No.05. This is not displayed on his base clothing. Meursault is also of considerable height. He is the tallest amongst all the other sinners.

His clothing consists of a white long-sleeved dress shirt, mostly covered by a black, low-cut waistcoat tucked into his black belt. Tucked beneath this waistcoat is a red tie. Atop all this, Hong Lu wears a long black coat that reaches just above his ankles. The long sleeves of this coat have accents of red at the end of each sleeve. Inside of this coat, there seems to be a red color. This coat has his Sinner number on his left, and a metal pin inscribed with writing on his right.

Heathcliff is depicted as being a tall and well-built man with messy dark brown hair parted on the right side of his head. He possesses sharp, glaring eyes that are a shade of dark purplish-blue. His eyebrows are the same shade as his hair and are both slit, his right eyebrow having two slits and his left just one. He has a dark skin complexion with an excessive number of scars littering his arms and going all the way up to his cheeks. His work uniform is lacking the typical long black leather jacket, instead wearing a shoulder holster which is strapped around his chest and shoulders, with his ID hanging below his right breast. The sleeves of his Limbus Company white T-shirt are rolled up to his elbows. He wears a red tie, black suit pants with a black waist belt and dark gray shoes. His weapon of choice is a long metal bat with bandages wrapped around the handle and the word "REVENGE" written in sharp letters on the barrel, which Heathcliff holds in his right hand and rests over his shoulder. After the events of Canto VI, he refashioned the bat to spell out "REMEMBER". Notably, although difficult to catch, Heathcliff wears a ring on the pointer finger of his right hand.

He also has a cockroach on his right shoulder that can frequently be seen his ID's.
