A page detailing The Coma's cast. Due to the series' heavy focus on lore and secrets, all spoilers will be unmarked.
Humans
A freshman student at Sehwa High, and the playable character of the first game. He picked up an amulet that Taehoon dropped, which turns out to be a Relic that ends up transporting him into The Coma when he falls asleep during his exams.
Youngho ends up failing at properly escaping The Coma and is rendered comatose and hospitalized in the waking world. The second game reveals that he has been stuck in The Coma since, and has been fighting for survival.
- Action Survivor: Thrown unexpectedly into The Coma and managed to live. In the sequel, he managed to remain in The Coma for years and is little worse for the wear.
- Big Damn Heroes: Drags Mina onto a motorcycle, saving her from Dark Song, and rides her to the Songreung Police Station.
- Blessed with Suck: The second game reveals that Youngho is what is called a Cold Soul, someone who can persist in The Coma indefinitely without succumbing to its effects like most other people. Unfortunately, this means he's the perfect choice for becoming the Vessel for Vicious Sister.
- Childhood Friends: With Mina Park, having known her since elementary school.
- Distressed Dude: Ends up taken hostage by Vicious Sister and needs to be rescued by Mina.
- Exhausted Eye Bags: Sports them in the second game, showing how difficult surviving and sleeping in The Coma can be.
- Fire-Forged Friends: With Yaesol, implied to have been built up over the interim of the time he spent in The Coma between the two games. They mutually respect each other.
- Grand Theft Me: What Vicious Sister intends to do with him in the second game. In either ending, she fails.
- In the Hood: Wears a hoodie over his school uniform in the second game.
- More Hero than Thou: The second game has him lock Mina into a room, citing that Seho and Vicious Sister are too dangerous for her to confront, and that he'll go and retrieve the Relic they need to return home. Unfortunately, Mina's heritage means she is the one fit to perform the job.
- Noodle Incident: A note found in his hideout shows that he was fooled by the Dokkaebi and cannot trust him anymore after having gotten an elixir from him that turned him into a girl.
- Seriously Scruffy: The second game shows him disheveled, scarred, and exhausted, showing how much it took for him to survive in The Coma for so long.
- So What Do We Do Now?: The good ending of the second game has him ask Yaesol what she'll do now, since Vicious Sister was defeated.
- Spanner in the Works: Nobody and no thing wanted Youngho in The Coma. The Shade tried desperately to get him out of there.
- Sudden Sequel Death Syndrome: Will die in the bad ending of the second game.
- Took a Level in Badass: Managing to survive in The Coma for what amounts to years required him to do this.
A freshman student at Sehwa High, and the playable character for the second game. A shadow version of her appears to Youngho in The Coma and is part of a sidequest. She ends up picking up the amulet that took Youngho to The Coma.
Mina finds herself in The Coma and has to fight for survival, learning that Youngho is supposed to be sacrificed during the Super Blood Moon, and that she is a descendant of Sumi Park, which makes her a shamanka.
- Aesop Amnesia: She calls out Myung-gil at the end of the first game, yet the second game has her incapable of standing up to him. Mina re-learns standing up to him at the end of the game.
- The B Grade: Miss Song kept her behind after class to discuss her latest English grade, which was a B+ that leaves Mina disappointed.
- Beauty Is Never Tarnished: Subverted, as Mina getting her max health decreased will lead to her model getting visible damage. Her portrait will have scratches on her arms, a bruised lip, and bandages.
- Childhood Friend: Has been friends with Youngho since elementary school.
- A Friend in Need: Subverted, with her realizing that her friendship with Da-hyun was a one-sided version of this. She claimed that Da-hyun could count on her when in need, but Mina had let her down a lot. Part of the game involves Mina realizing this and wanting to become a real friend to her.
- Good Feels Good: Going through The Coma has her realize that taking care of her problems herself feels pretty satisfying.
- Took a Level in Badass: Required to make it through The Coma. Doubled with her standing up to Myung-gil, too.
An experienced Ghost Vigilante that is travelling to The Coma frequently. her current duty is to investigate the going-ons at Sehwa High, since things had become wild there, and try to purify it.
Yaesol remains as a bit of a mentor figure to Mina in the second game, giving her tips on how to advance when needed. She wants to stop Vicious Sister, knowing that the current Super Blood Moon is the only chance remaining.
- Beauty Is Never Tarnished: Has her arms wrapped in bandages, but she has no injuries on her face. Could be explained that she has enough experience to avoid most injuries.
- Cynical Mentor: Plays this role towards Youngho in the first game, bluntly telling him things to do and to not do stupid things. She explains a bit more with Mina in the sequel, but still doesn't tell her some basic rules of The Coma.
- Damsel in Distress: Suffered from poisoning in the second game and needed Mina to bring her the remedy.
- Fire-Forged Friends: With Youngho, implied to have occurred over the course of time he spent in The Coma. They mutually respect each other, which is a big step up from how she saw him as a bumbler in the first game.
- Hero of Another Story: Little is known about Yaesol, although her knowing much about The Coma makes it clear that she is well-traversed in it.
- Locked Out of the Loop: She was unaware that the Ghost Vigilantes were going to kill Youngho because they didn't have access to Moon Incense.
- Mentor in Sour Armor: For all the guidance she gives Youngho, she's still surprised when he lives (and makes it clear she has bigger priorities than his survival).
- Rogue Agent: Denounces her allegiance to The Order if it's true that they were planning to kill Youngho from the beginning.
- Vague Age: Looks to be not older than Youngho and Mina, but Jang-mi refers to her going soft in her old age, and an unchanged Yaesol was seen in a flashback that took place 60 years ago. Even when Mina asks her age, Yaesol merely handwaves her question aside.
A freshman student at Sehwa High. He found an old recorder in the school's storage and found himself taken to The Coma. He became drunk with power that The Shade gave him. Since he lost the recorder, The Shade possessed his body.
Seho actively works to keep Mina away from everything, locking her into the Police Station and sabotaging the trains at the Subway Station. He wants to stop the Ghost Vigilantes from getting their hands on Youngho.

- Grand Theft Me: The Shade possesses him in The Coma, implying that she controls him in the waking world.
- Left Hanging: His ultimate fate is unclear in the sequel, with him being mentioned to not have been in school for some time.
- Rejection Affection: Despite Mina having no interest in him, Seho wanted her to be taken to The Coma, so that they can rule together as king and queen of Sehwa High.
- Scary Shiny Glasses: His glasses were always shiny, but once it becomes clear how horrible of a person he is, they become this.
- Start of Darkness: Finding himself in The Coma and being shown how he can manipulate reality in it, Seho became influenced by The Shade's words. A note written by him claims that he considers himself king of the school.
A freshman at Sehwa High and school bully. He bullied Youngho and Seho, but Taehoon apparently got the worst bit of it off, to the point that rumors claim that Myung-gil's bullying is the reason for Taehoon's attempted suicide.
Myung-gil retains his bullying demeanor in the sequel, and his incessant focus on Mina becoming his girl. He had Da-hyun give her a love letter, wanting Mina to finally make things official.
- Abhorrent Admirer: Has a crush on Mina, who considers him gross and dislikes his personality.
- The Bully: He insults and mocks people he doesn't like, and gives them demeaning nicknames. Seho is forced to buy him pizza bread, among other things.
- Curse: Was cursed by Seho in the first game to rapidly starve, no matter how much he ate. His shadow version in The Coma had a black hole in his stomach and face.
- Jerk Jock: Considered the baseball star of Sehwa High and considered a catch by most of the female students, but his personality is disgusting.
A freshman at Sehwa High and Mina's best friend. She was only mentioned by name in a note of Mina's in The Coma during the first game, but appears in-person in the sequel.
Da-hyun is sick of Mina using her to get Myung-gil off her back and tells her to grow a spine already. A shadow version of herself appears in The Coma before Mina and sends her on quests to figure things out.
- Abusive Parents: Her father was emotionally and physically abusive.
- Big Damn Heroes: Her shadow version appears to Mina in the final moments of the game, giving her the missing piece of the cryptograph that tells Mina how to destroy the eldritch vines.
- A Friend in Need: Always there when Mina needed her, but realized that Mina was never around when Da-hyun needed her. Her shadow version in The Coma is infuriated over this long-standing imbalance.
- In-Series Nickname: Rash Girl. She absolutely despises being called that, since it was given to her through bullying.
- Scars Are Forever: Has burn scars all over her back from when her father splashed hot tea over her years ago.
- Stepford Smiler: Tends to have a smile on her lips, but her diary reveals that she's been putting up a look of positivity for a long time because of her past.
- There Are No Therapists: Averted, as they do exist and Da-hyun has frequent meetings with psychologists at the hospital to have therapy.
An English teacher at Sehwa High. She doesn't know anything about The Coma, but it's clear that there's a connection between her and the picture of Sumi Park in her amulet.
Miss Song loves her students and wants them to succeed, and worries about Youngho and Taehoon being hospitalized.

A woman that has a profound connection to everything in the game. An old portrait of hers is in the amulet that belongs to Miss Song and that serves as a Relic to The Coma. She chose the group of Ghost Vigilantes to send out to stop Vicious Sister in the sequel.
- The Chessmaster: Planned the events of the sequel sixty years ago, including having Jang-mi raised to believe herself to be the chosen shamanka to rid the world of Vicious Sister, while Sumi actually planned for them to fail.
- The Heavy: Sumi is responsible for most of the actions in the sequel, starting with her being the one that created Vicious Sister, albeit unintentionally. She also gave the Moon Incense to her successor, ensuring that Vicious Sister couldn't be stopped until the fourth Super Blood Moon.
- I Have Many Names: She's known as the head chairman of the Sehwa Institute to most of the public, with the Ghost Vigilantes calling her The Minister. Yaesol simply calls her by her name.
- Tragic Keepsake: The rosewood recorder. Her brother taught her how to play it when she was young, and it was her memento of him after he died. She lost it in The Coma, leading to it becoming a possession and personal property of Vicious Sister.
One of the Ghost Vigilantes sent to stop Vicious Sister in the sequel. She's a middle-aged shamanka and was raised from an early age onward to perform her duty as such well. She appears in the Dokkaebi Market, buying some Spectral Incense.
- Red Herring: She was called in to be the shamanka to defeat Vicious Sister and her death is treated as the lynchpin to go with Plan B to get rid of that shade. Turns out that Sumi Park intentionally did this, including having Jang-mi raised to believe her destiny as the one to defeat Vicious Sister, because she knew Jang-mi would never be able to do it.
- We Hardly Knew Ye: Jang-mi barely appears on-screen before being killed by Dark Song. She does have four notes to find in the Dokkaebi Market, that describe her raising as a shamanka.
- What the Hell, Hero?: Calls Mina out for giving out her name to someone in The Coma.
- The World's Expert (on Getting Killed): As someone raised to be a shamanka, Jang-mi knows everything about The Coma, what Vicious Sister is planning, and what the Moon Incense is, and how to use it. She gives no such information to Mina before being unceremoniously killed off.
One of the Ghost Vigilantes sent to stop Vicious Sister in the sequel. He's an older, Catholic priest that joined the Ghost Vigilantes when he encountered a demon that was actually a shade from The Coma. He appears in the Sehwa Hospital, having gone there to sanctify the Holy Water of Separation and finding the vessel Vicious Sister plans to possess.
- The Generic Guy: He's a priest and Ghost Vigilante. That's all that's known about him and to find out about him, before and after he gets killed off.
- We Hardly Knew Ye: Spent little time hanging around before Dark Song kills him in the hospital morgue.
A new, native English teacher that joins Sehwa High. He turns out to be one of the Ghost Vigilantes sent to stop Vicious Sister in the sequel. Chance is off doing his own thing most of the time, but is there for Mina when it comes to tips on how to advance. Or just to improve her English skills.
- Go On Without Me: Tells Mina to go on ahead to the school, leaving him behind to fend off Mad Shadows when their Spectral Incense goes out prematurely. Chance can survive, if the player manages to find a Spectral Incense and return before activating the Point of No Return for the game.
- Phenotype Stereotype: A native English speaker with blond hair and blue eyes.
Coma Citizens
The primary antagonist of the two games. She mostly played a small role in the first game, possessing Seho and wanting to get her flute Relic back, but was the one that wants Youngho to get out of The Coma.
She turns out to be a Fettered Shade of Sumi Park, created when Sumi was too grieved over her brother's death. She created the Dark Song to stalk the school and mock Sumi Park, and plans to possess Youngho's body to infiltrate the waking world.
- Alternate Character Interpretation: Sumi believes that Vicious Sister has good in her and can be redeemed, without killing her.
- Enemy Without: Of Sumi Park, coming into existence when Sumi mourned her dead brother.
- Eyes Out of Sight: Her long hair covers her eyes completely.
- Femme Fatalons: Has elongated limbs and claw-like hands.
- Orcus on His Throne: Does little to actively stop anyone in The Coma, preferring to have Dark Song do the work. She does stalk Mina in the final confrontation.
- Slasher Smile: Her default expression.
- Sudden Name Change: Merely referred to as The Shade in the first game, but gets called Vicious Sister in the second game.
The active antagonist of the two games, stalking the halls of Sehwa High and looking for anyone that shouldn't be there. She repeatedly stalks Youngho, and gets progressively faster and stronger.
She keeps her role in the second game, now following Mina around into the other locations that she visits, expanding her territory beyond the school.
- Black Eyes of Evil: Instead of teeth for eyes, the Recut edition had her sport these instead.
- Evil Counterpart: To Miss Song. This was done intentionally by Vicious Sister because she wanted to mess with Sumi Park, making her beloved granddaughter's image roam locations and kill people.
- Eyes Do Not Belong There: The original version of the first game had her eventually have sharp teeth for eyes.
- Femme Fatalons: Has elongated limbs and claw-like, bloody hands.
- Implacable Man: Cannot be damaged. The second game gives Mina a chance to temporarily get out of her grasp by using mace, but still needs to go hide.

- Sudden Name Change: Referred to as The Killer in the first game, with a more fanon name of Dark Song. The second game referrs to her as a Flesh Thrall.
A specific sub-species of Shades found in The Coma. Every location has their share of Notemen, but there is also one Shade the game specifically referrs to as 'the' Noteman. He overlooks all the locations. The job of Notemen is to write down the rumors, emotions, and memories of people from the waking world. These end up being what can be read on all sorts of surfaces, written in any kind of substance.
- Couldn't Find a Pen: Notemen write on anything with anything. One notewoman in the Subway Station asks for toilet paper and a lipstick to write her memos.
- Creepy Good: The Noteman has long claws, a creepy grin when he isn't scowling, and overall has a weird sense of humor. But he is a non-violent type of Shade and does help Youngho and Mina out at times.
- Everyone Calls Him "Barkeep": With knowledge of someone's name being a bad idea in The Coma, most Notemen tend to have no actual name given. They are referred to as Noteman or other descriptive names.
- Mr. Exposition: The Noteman himself is basically a plot device to explain certain aspects of The Coma to people like Youngho and Mina.
