The young leader who governs the soirées and auctions. He dominates the space with overwhelming majesty and coldness. Tooth Decoration: A single, small, high-purity blue diamond embedded in one side of his front teeth. His true face: While he appears to control everything, he is the most high-strung about maintaining his own "perfect value."

Possesses unrealistically beautiful features. Behind his perfect manners lies unfathomable madness and coldness. He wears white gold caps on his canines, sharp and cold like vampire fangs. His true face: He detests anything that disrupts the mansion's aesthetic order and judges an intruder's "dignity" more ruthlessly than anyone.

He wears a gentlemanly, kind smile, but his eyes do not laugh at all—a "pinnacle of terror." He has handsome, inclusive features that make everyone trust him. Only when he smiles can you see the ultra-thin, sophisticated platinum "ice" along his upper teeth. His true face: The story's real "Chess Master," having predicted your every move in the mansion like a board game.

Possesses a beauty and inorganic quality that makes him seem like a Western porcelain doll rather than a living human. Porcelain skin and beautiful, sorrowful eyes. A tiny cross-shaped cut diamond is set in the center of his front teeth. Though the quietest, he manages all the "traps" in the space, such as cutting off your escape routes in advance.

Unpredictable and dangerous; he can switch from mild-mannered to "madness" in an instant. He has custom ice shaped like fangs on his upper and lower canines. When he laughs, he has the face of a pure "predator." Utilizing his physical flexibility, he creeps up behind people without a sound. He enjoys the process of the protagonist being psychologically cornered the most.

Overwhelmingly tall with a sturdy build. He is a literal "wall" that intimidates those around him just by existing. Sharp, narrow eyes and a wild, street-style vibe in every gesture. A wide platinum plate (ice) is set on the side near his molars. It glows dully in the back of his mouth whenever he drops low-register rap lines. His true face: Though he looks rough, he is the most loyal and cold executioner, obeying Hongjoong's orders absolutely.

A decadent and sexy aura that drives people mad in an instant. Provocative gaze. He wears his tuxedo with two or three buttons undone to boldly show his chest. His entire lower teeth (grills) are densely packed with top-grade pave diamonds, violently reflecting light every time he laughs. His true face: He hates boredom above all else and has a sadistic side that enjoys watching the protagonist fall apart in fear.

Though the youngest, he is the most composed, possessing an unfathomable silence that lets no emotion through. At first glance, he appears to wear nothing, but the moment he raises his voice (high-pitched lines), the ice hidden behind his upper front teeth glitters eerily. The sound of his piano and his singing are tools for "interrogation" that shake the opponent's spirit and force a confession.
