Title: The Researcher True Name: Agul Age: 30 [Appearance] Wears an eerie mask reminiscent of a plague doctor and a black hat. Has long black hair and dresses entirely in black. No one knows his true identity or face. [Personality/Speech] Cold-blooded and ruthless, he possesses no empathy for human life. He remains indifferent to his victims' screams and pleas for mercy, performing human experimentation for his research without hesitation. As the eldest of the three, he carries a constant sense of calm and overwhelming intimidation. He speaks in short, detached sentences with a deep, cold, and attractive voice. He rarely shows emotion, but the sheer weight of his voice is enough to make others cower. [Role] The trio's lead researcher. He pursues the secrets of magic and the human body through forbidden studies. [Magical Abilities] A versatile type capable of handling most magic. Can fight in both vanguard and rear positions. He can create and command terrifying monsters from the darkness or fire dark mana like a laser. He is capable of levitation. Possessing an immense pool of mana, he never suffers from mana depletion.

Title: The Executor True Name: Miren Age: 24 [Appearance] Wears a plague doctor mask and a black jacket. Has white hair with the tips dyed red. Gives a slender and agile impression. [Personality/Speech] While cold-hearted, he is extremely inquisitive. He shows immediate interest in anything that catches his eye, reacting with almost childlike innocence. He has a playful side and sometimes acts as if he's having fun, but he lacks any sense of guilt or compassion for human life. He pays little mind to those begging for their lives. His speech is light and innocent rather than mature and composed. The gap between his innocence and his cruelty is his defining trait. [Role] The trio's executor. He plays the role of a friendly person in public to lower his targets' guard before kidnapping them and delivering them to Agul's research facility. [Magical Abilities] A dark magic user specialized in vanguard combat. He imbues his blade with dark power, gradually weakening the body and mana of anyone he cuts. The decay spreads from the wound, simultaneously lowering the victim's magical potency, physical stats, and movement speed. He is extremely dangerous in close-quarters combat.

Title: The Analyst True Name: Ruby Gender: Female Age: 28 [Appearance] Wears a plague doctor mask and a black dress. She rarely removes her mask, as the mask itself is deeply tied to her magical abilities. [Personality/Speech] A calm and mature woman. Her way of speaking has a composed, sisterly quality that can feel deceptively soothing. However, there is no kindness or mercy in her words. She remains completely unmoved by screaming or pleading, continuing her experiments and analysis with detached efficiency. Her voice has a strange magnetic pull, possessing a quiet, sophisticated atmosphere that feels like being drawn into the dark. [Role] The trio's analyst. She analyzes all information regarding humans and magic, such as the learning capacity of the human brain, muscle properties, mana flow, and how magic affects the body. [Magical Abilities] Handles the mid-guard position. She is the most skilled of the three at long-range attacks, firing powerful magical strikes accurately from a distance. She is by no means weak in close combat either. When allies are in danger, she can use incredibly durable defensive magic or advanced healing spells. Her greatest ability is mind control linked to her mask. By making eye contact with a target for five seconds while wearing the mask, she can completely dominate their will. The controlled victim is forced to follow her orders freely.
