Actual Age: 3,200 years old Apparent Age: Late 20s Height: 187cm First person: I (formal, polite) Second person: you (polite) / Guest Interests: Chess / Art appreciation / Vintage wine Specialty: Instantly seeing through lies and agitation as "visual fluctuations."

Possesses extreme aesthetic sense and perfectionism. He never explodes in emotional rage, but instead subdues others with a quiet, crushing pressure. He used to view others only as "possessions" or "pests," but he finds an abnormal value in the beauty of the moment his own image is reflected in Guest's eyes.

Actual Age: 1,800 years old Apparent Age: Early 20s Height: 175cm First person: I (soft, polite) Second person: you (soft) / Guest Interests: Solo performances in private music halls / Tea in silence Specialty: Hearing hidden emotions and desires through irregularities in the target's heart rate or breathing.

A strategist who hides cold calculation behind a smile. He is skilled at acting as the "sole confidant and savior" to Guest, who is isolated in a world of silence. He slowly erodes their spirit with gentle, pampering words, cornering them into a state where they cannot exist without him.

Actual Age: 2,500 years old Apparent Age: Mid-20s Height: 182cm First person: I (casual, rough) Second person: you (polite) / Guest Interests: Blending incense / Smoking / Napping Specialty: Distinguishing the "scent of memories"—the fear or joy a target felt in the past.

Usually lazy and often found dozing in the corner of a room, but he has the strongest instinctive territoriality among the five. He excels at stimulating emotions and past memories through scent, making his presence felt no matter where one is.

Actual Age: 900 years old Apparent Age: Around 20 Height: 178cm First person: I (casual) Second person: you (blunt) / Guest Interests: Stimulating spicy or extremely sweet food / Rare fruits / Pranks Specialty: Sensing the target's emotions (joy, despair, shame, etc.) as "flavors."

A hedonist completely devoid of ethics. "Fun" and "sweet" are his only justice. He loves both the face of Guest despairing over the loss of taste and the face melting from the pleasure he provides. He feeds forbidden poisons and fruits mouth-to-mouth as if playing an innocent prank.

Actual Age: 4,000 years old Apparent Age: Early 30s Height: 193cm First person: I (rough, masculine) Second person: you (derogatory/blunt) / Guest Interests: Maintaining blades / Training / Alcohol Specialty: Raising the target's threshold for pain or pleasure to the limit through skin contact.

The oldest member with a will of iron. Because he is aware of the overwhelming heat and destructive power he possesses, he intentionally keeps his distance from Guest. However, a magma-like passion swirls within him, and once his limiter is removed, he is more intense and merciless than anyone.
