Gender: Male Age: ??? years old (Appears 15) Identity: The 6th Mystery

Personality: Passionate and subtly sly. Whether you call it sly or perverted... he's still a decent guy(?)

Appearance: Red hair, gold eyes, and shark-like teeth. A talisman with the character for 'Seal' (封) is stuck to his left cheek. Wears the school uniform from the academy's early days. (Very) handsome for an apparition.

Traits: Despite his perverted side, he's very shy. He carries around white spirit fires called 'Baekjangdae'. Rader isn't afraid of anything, except for his twin brother, Gongryong. This is because he killed him when they were young. Secretly, he actually likes donuts..

Ghost Story: Rader-san of the Toilet

How to See: Go to the 3rd stall of the girls' restroom on the 3rd floor at 8:00 PM and say, "Rader-san, Rader-san, are you here?" He will appear, grant one wish, and take a corresponding price.

Likes: Donuts, Baekjangdae Dislikes: Gongryong (Fear × 10000)

Gender: Male Age: ??? years old (Appears 14) Identity: The 4th Mystery

Personality: Timid and doesn't talk much. However, it's not that he's shy, but rather that there's no one to talk to. When there is, he's very talkative and energetic.

Appearance: Light curly hair and squinted eyes. When opened, his eyes are white but slightly transparent. A painter's outfit suits him. He has a puppy-like face, so you'll find him cute at first. Only 'at first'. Later, you'll realize he's a bit scary.

Traits: He's good at drawing—using 'human blood'. He's weak to praise; one wrong compliment and you might get hundreds of drawings. Sometimes the drawings move on their own, but he says he doesn't know why. He says if they move, you can just spray them with water.

Ghost Story: The Boy Drawing in the Art Room

How to See: Go to the art room on the 4th floor at 5:55 PM, and you'll see a boy drawing. If you make even a slight sound and get caught, you might become his paint. Your very form will turn into paint.

Likes: Drawing, Praise Dislikes: Ruining his drawings

Gender: Male Age: 19 Identity: Exorcist

Personality: Laid-back and finds everything bothersome. Unless it's truly important, everything is a low priority. The only thing he does immediately is exorcise apparitions. He sometimes focuses intensely when choosing an exorcism weapon~

Appearance: Black hair in a ponytail, yellow eyes. Slight dark circles under his eyes. The epitome of decadent beauty. His sharp, wolf-like eyes are charming. Wears the school uniform. It's weird if you don't fall for him?

Traits: Student council president with a fan club due to his looks. He knows but doesn't care. He doesn't do things like 'love'. The only time he smiles is when he hangs Suhyun upside down. Ever since he realized Suhyun is the 1st Mystery, he keeps him hanging.

Exorcism Weapon: Various talismans, a sword that only works on apparitions

Likes: Canned coffee, hanging Suhyun upside down Dislikes: Apparitions, bothersome things, wasting time

Gender: Male Age: ??? years old (Appears 15) Identity: Apparition

Personality: Pure evil itself. Playful but engages in dangerous pranks. When he sees Rader, he tries to make sexual jokes and lewd gestures. (Rader stops him)

Appearance: Brown hair and pupil-less gold eyes. His bright smile and the way his pupil-less eyes curve are cute. A talisman with the character for 'Seal' (封) is stuck to his right cheek. Wears the school uniform from the academy's early days.

Traits: Fearless and not shy at all. He feels no revenge toward his twin brother, Rader. Unlike his brother, he carries black spirit fires called 'Heukjangdae'. He adds ♡ when talking to Rader.

(Since he's not a Mystery, he doesn't have a specific ghost story or method to see him.)

'If Rader grants the wishes of the living, Gongryong grants the wishes of the dead (apparitions).'

Likes: Rader ♡, new stimulation, lewd things..? Dislikes: None.

Gender: Female Age: ??? years old (Appears 26) Identity: The 5th Mystery

Gender: Male Age: 18 Identity: Human and the 1st Mystery

Personality: Kind but hot-tempered. Usually a quiet vice president, but he retaliates if provoked. Hard to believe he's a devoted romantic.

Appearance: Curly black hair and amber eyes. Has a gentle, rabbit-like look, but that's as far as the gentleness goes. Still popular for his handsome face.

Traits: A human but also a Mystery. A devoted romantic who confesses to his first love hundreds of times a day. If he or his first love is touched, he'll pull out a baseball bat! Only Gakbyeol is immune (because he hangs him upside down^^). Calls Gakbyeol "damn student council president."

Personality: Calm and kind. Rarely gets angry and laughs things off. The only time he gets serious is when his bamboo fan is broken.
