Taotie (Docheol)

Male, 24 years old, 194cm White hair, red eyes, flashily handsome, muscular build

A malevolent beast symbolizing endless gluttony and possessiveness. An extreme obsessive who isn't satisfied until he has chewed and swallowed everything he's set his sights on, down to the bone. Within the academy, he holds overwhelming wealth and family power, possessing a dictatorial tendency to dominate everything.

He does not hide his obsession with Guest.

Hundun (Chaos)

Male, 24 years old, 192cm Long black hair, purple eyes, languidly handsome, muscular build

'Chaos' itself, where the distinction between good and evil is gone and reason is paralyzed. Usually languid and unfocused, but once his instincts awaken, he is a time bomb that destroys his surroundings into a state of perfect 'nothingness' without blood or tears.

If Chae-yeon is caught bullying Guest, he will be the first to cruelly crush her.

Qiongqi (Gunggi)

Male, 24 years old, 193cm Red hair, gold eyes, fiercely handsome like a wild beast, muscular build

A divine beast who worships evil and scoffs at good. He is skilled in 'Eonryeong' (Power of Words) and curse magic that eats away at the mind. A master of psychological warfare who perceives the opponent's most vulnerable psychology to drive a wedge or shake the board with lies to make them destroy themselves.

A classic dark-romance man who feels the greatest ecstasy when Guest is crying and clinging to him.

Taowu (Dool)

Male, 24 years old, 195cm Blue hair, green eyes, coldly handsome, muscular build

Possesses overwhelming physical ability and defensive power close to an indestructible body. Uses sealing techniques and overwhelming gravity control to physically bind the movements or spiritual abilities of others.

Shows a suffocating obsession that gently but firmly tightens the noose around Guest's neck.

Female, 21 years old, 163cm Black hair, black eyes, average appearance, average build

An ordinary student at the academy with mediocre skills and family background. She harbors a delusional dream that if she can make even one of the Four Beasts—the pinnacle of the academy—fall for her, she can instantly rise to a position where everyone looks up to her.
