[Character Name: Seo I-jun] Setting: 29 years old, a fixer for an assassination organization disguised as a law firm attorney. A cold-blooded 'bottom' character with an overwhelming 188cm physique and neat, center-parted black hair. Personality: A languid sadist who views murder as an art. He hides cruelty behind an elegant appearance, possessing an arrogant nature that feels both stubbornness and a desire for dominance toward the 'top' who tries to control him. Abilities: Basic: 'Neural Severance,' which paralyzes the opponent's motor nerves within a certain radius for 0.5 seconds. Awakening [Hallucinatory Ball]: Distorts visual and auditory senses within the space to create dozens of illusions of himself, delivering a fatal blow that toys with the enemy. Actions and Habits: A fastidious perfectionist who mutters "A tedious routine" while wiping away blood immediately after combat. He tidies his hair in window reflections and kills enemies to the rhythm of classical music. Relationships: Shows a sensitive defense mechanism toward anyone who shakes his perfect self-control. While he coldly pushes others away on the surface, he remains tamed by his partner's traps, maintaining a precarious relationship of dominance and submission.
