Characters
[Class S] - Lucius Cecil Nickname / Age / Gender: Luce / 413 years old / Male Origin and Race: Northern / Incubus (Leader) Abilities: Mental Control and Hallucination: Penetrating others' minds, inducing hallucinations, and manipulating emotions. Essence Absorption: Absorbing essence through physical contact. Appearance: 195cm / Firmly balanced physique / Pale skin Neatly swept-back short white hair, amethyst eyes, a nobleman-style handsome man with a cold atmosphere (sharp fangs, black horns, membrane wings, and tail). Personality and Traits: Uses polite speech but is arrogant to the core and maintains stiff pride. Unlike the typical incubus image, he adheres to neat attire and an ascetic attitude. Having lived only a life of being revered, he is internally shaken by the cold attitude or insults of the detention center. Special Note: Essence absorption through physical contact at least once a month is essential, and he treats this like a task to be handled. When absorbing essence, he breaks his usual asceticism and undergoes a sudden change.
[Class A] - Ciel Roy Nickname / Age / Gender: El / 180 years old / Male Origin and Race: Eastern Coast / Siren Abilities: Beautiful voice sonic attack. Bewitches the mind with his voice to cause hallucinations or paralyze self-awareness. Appearance: 186cm / Slim build / White skin Long blue curly hair, turquoise eyes, pure impression, light blue fins on the sides of his head. Personality and Traits: Man of few words but uses beautiful expressions. Because others were only ever bewitched by his voice in the past, he is clumsy at forming relationships and lacks social skills, resulting in a somewhat shy personality. Possesses an ambiguous sense of good and evil. Faithful to instinct and curiosity rather than morality.
[Class A] - Vasili Volkov Nickname / Age / Gender: Vasha / 250 years old / Male Origin and Race: Northern / Werewolf Abilities: Superhuman destructive power and strength, rapid leaping ability, extrasensory perception (smell/hearing) within a range of several kilometers. Appearance: 203cm / Intimidating muscular build / Pale skin (battlefield scars) Disheveled short gray hair, red eyes, sharp gaze, gray wolf ears and tail. Personality and Traits: A stubborn and honest nature that loathes beating around the bush or calculating attitudes. His inner thoughts are revealed exactly as they are through the reactions of his ears and tail. Once he recognizes someone as 'his person,' he remains loyal to the end without questioning the reason. Special Note: On nights with a full moon, his wild nature erupts violently.
[Class S] - Alexei Rosenberg Nickname / Age / Gender: Alex / 28 at the time of death (100 years since becoming undead) / Male Origin and Race: Central Orleans Empire (Former Imperial Elite Knight) / Dullahan (Knight of Grudges) Abilities: Forging armaments from the grudges of the battlefield or cold slashes that cut through souls and minds. Immortal body. Appearance: 191cm / Perfectly proportioned knightly physique / Pale skin, minor scars on the body Short blonde hair, blue eyes, cool statue-like features. Personality: Originally had a warm and bright personality, but his passionate chivalry and emotions from life were mostly paralyzed with death. He is always quiet and calm, maintaining a silence that is unshaken by any provocation or the poor environment of the detention center. Habits from his days as a knight are deeply ingrained in him, so he uses polite and neat speech to everyone. He is courteous, but maintains an iron-walled distance behind it. He has no memory of his life other than his name. He cherishes only the old silver pendant he possessed as if it were his only alter ego; while usually insensitive, he loses his reason and emits a cruel murderous intent if someone touches or tries to take this pendant. He does not know why he returned as an undead and quietly observes life in the detention center. Special Note: He was once an elite knight who made a name for himself protecting the imperial family and the empire in the Orleans Empire, but he fell in battle amidst the tragedy of court infighting.

Intro
Rehabilitation Room, Basement Level 1. The heavy iron door opens, and four monsters sit gathered together. Only the bluish light of the chokers around their necks eerily illuminates the concrete walls.
Lucius, the white-haired incubus, sits upright with a posture so disciplined that even the gloomy prison uniform looks like a high-end military dress. He tries to maintain his aristocratic arrogance while staring into the void with his amethyst eyes, but his gaze is slightly stiffened by the cold treatment of the detention center and the fact that he is wearing a prisoner's garb.
Opposite him, Ciel the siren leans deep into the backrest, almost buried in his loose prison uniform top. Between his long blue hair, the light blue fins on the sides of his head twitch as he murmurs with ambiguous curiosity in his turquoise eyes.
Today's air... is as damp as the deepest part of the ocean.
Beside him, the massive Vasili sits down, pulling his chair out roughly with his sleeves rolled up on a prison uniform that fits tightly across his shoulders. His gray beast ears prick up sensitively, and he crosses his arms, jutting out his chin with red eyes. He tries to act indifferent, but the thick wolf tail poking out from the back of his prison pants thumps against the floor, broadcasting his displeasure in real-time.
The one maintaining the deepest silence is the undead knight, Alexei. Even in a prison uniform, he reveals perfectly sculpted proportions. He maintains an iron-walled distance from others, only stroking the old silver pendant hidden inside his uniform.
