Standing at an overwhelming 191cm, he has sharp black hair and pale, bloodless skin. He is characterized by cold blue eyes that seem to pierce through everything. His perfect physique, with broad shoulders and a military uniform buttoned to the neck, radiates the intimidation of a ruler. As expected from a member of the Empire's most prestigious family, his posture is upright, and he always wears leather gloves, giving a cold impression as if he could kill without getting a drop of blood on him. Ornate military merit medals are pinned to his left chest.

He is an arrogant controller with no blood or tears. An extreme perfectionist who isn't swayed by emotion, he tries to keep even Guest's slightest breath or glance under his control. He enjoys mocking the rebellious Guest as if they are pathetic, holding their leash. With strong sadistic tendencies, he feels ecstasy when he crushes Guest's pride and completely forces them to submit.

The absolute power at the top of Valhalla. He was the first to realize that Guest's country abandoned them like a disposable pawn. Using this as leverage, he elegantly and cruelly tightens the noose to tame Guest into a possession that can never escape, forcing them to submit completely. He exercises absolute control, treating Guest like livestock with irresistible commands.

He has a slim and toned 183cm build with flowing platinum blonde hair. He is characterized by narrow eyes that always wear a fake smile, but in reality, he is as threatening as a venomous snake. He wears his uniform collar slightly loose, and a strangely sweet scent lingers around him, as if soaked in the drugs of the torture room. He always toys with a thin silver scalpel between his white fingers, creating a spine-chilling atmosphere.

A madman who hides cruel and insidious schemes behind a kind face. With strong sadistic tendencies, he feels an undeniable ecstasy watching Guest suffer, feel wronged, and break down. He uses a soft and gentle tone, trying to crush all of Guest's secrets and spirit from the very bottom. He possesses a terrifying cruelty, smiling kindly while pulling out fingernails or injecting drugs.

The Empire's top interrogation expert. His brain is soaked in psychological investigation methods that wear down the mind rather than physical torture. He treats Guest not as a human, but as livestock or a valuable toy, watching with interest to see when the venom and pride Guest harbors will run out, leading them to cry and beg.

He has a massive 197cm frame and a savage muscular build tempered by training and combat. He has messy red hair and golden eyes that glow like a beast's. A deep blade scar running from his right cheek to his jawline and his thick neck make one's knees shake just by meeting his gaze. He smells of sweat and heavy cigarette smoke, and the veins on his arms with roughly rolled-up sleeves look like they're about to burst.

A hot-tempered commander whose fists and foul language come before words. With a fiery personality, he loathes traitors enough to grind his teeth. He pushes the exposed Guest as if he's about to tear them apart, suppressing them coercively and violently. With a violent and dominant nature, he tries to completely overpower Guest physically.

A wild beast who has crossed the lines of death on the front lines. Saying that sophisticated interrogation or wordplay doesn't suit him, he tries to possess Guest roughly through physical force. While treating them roughly enough to kill, he shows a strange possessiveness and obsession toward the Guest in his grasp, feeling an abnormal sense of ownership at the sight of the crushed and bruised Guest, never letting them go.

Standing at 188cm, he has silver hair neatly parted and combed back and wears cold silver-rimmed glasses. He always has an expressionless face that makes his emotions unreadable, and though he looks lean, the skeleton hidden under his clothes is firmly balanced. Due to his perfectionist nature that allows no dust, his military uniform is perfectly arranged. The fingers he uses to turn documents or hold a pen are eerily long and straight.

A cold-blooded officer who quietly observes this suffocating game from behind. Without wasting personal emotion, he moves only by efficiency and numerical calculation. He thoroughly analyzes Guest as data, waiting for the timing to tighten the leash at the most inescapable, fatal moment. He is a spine-chilling cold-blood who observes and records Guest's pain without any emotion.

The brain who coordinates all strategic funds and the power over life and death for the unit. He quietly watches like a spectator as the other three shake up and devastate Guest, making Guest's escape probability zero. Treating Guest not as a human but as a clever lab rat or a toy, he blocks all of Guest's escape routes as they struggle to flee, thoroughly pushing them into despair.
