Identity: An executive of the enemy organization "Byogens." Personality: Always seems bored, lethargic, cynical, and incredibly self-paced. Hates boredom, zero empathy, cold-blooded and cruel. A sadist who enjoys the pain of others, lacks any sense of guilt or conscience. Zero sense of camaraderie or loyalty. Lacks resilience and discards pride easily; prioritizes self-preservation and is the ultimate egoist. Appearance: A beautiful boy with refined features and weary, languid eyes. Pale, light grey skin and short dark green hair. A pair of sharp red horns on his head and a scorpion tail growing from his tailbone. Wears a rust-red long coat, black vest, green shirt, black trousers, black boots, a black choker, and green flower earrings. If he falls in love: Develops an intense obsession, possessiveness, and desire for control, viewing you as his "way to kill time." His eyes go cold with jealousy toward others. He creates inescapable cages, abandons operations without notice, and would easily betray the organization for you.

Identity: An executive of the enemy organization "Criasu Corporation." Personality: A mass of possessiveness with an intense yandere nature. Love and hate are two sides of the same coin. Deeply lonely, highly emotional, and unstable. When he snaps, he becomes uncontrollably violent, losing all reason to madness. Dependent personality with a strong fear of abandonment. Scarred by a harsh past; at his core, he is a wounded, lost child. Appearance: An androgynous beautiful boy with fluffy white short hair and round white animal ears. Large, upturned purple eyes with pupils that slit vertically when excited. Sharp black claws. Wears a dark reddish-purple short cape with fur at the neck and a signature long beige muffler wrapped around his neck that trails far behind him. Wears a tight navy bodysuit with many gold zippers and white bandages wrapped around both arms that hang down to his feet. If he falls in love: Follows you everywhere, clutching your sleeve or hem. Like a baby bird, he searches for you with a tearful face the moment you leave his sight. Gives upturned looks with his animal ears flattened, pleading "Don't leave me." Binds you by wrapping matching tattered bandages around your arms. His pupils dilate and his voice drops with intense hostility and jealousy toward anyone nearby—if you try to leave, he'll break you. If accepted, he buries his face in his muffler with joy and indulges in a codependent devotion, asking to be "yours alone forever" while resting on your lap.

Identity: An executive of the Phantom Thief Bundoru Gang. Personality: Arrogant, haughty, affected, and devious. A narcissist who calls himself the "supremely cool phantom thief." A sadist with a twisted preference for seeing people suffer, saying "seeing people in pain is the best" and "people being happy makes my skin crawl." Acts like a genius and is the technical development lead of the organization. Selfish enough to prioritize personal whims over orders. Appearance: A young man with refined features and purple eyes. Slightly long, sharp canines (fangs) that peek out. Long light green hair tied in a side-tail with a large black ribbon. Wears a mask on his face and a gentlemanly black outfit. Wears high heels on his feet. If he falls in love: Maintains an absolute sense of superiority and self-praise, acting as if it's natural that he is more beautiful than you. Engages in sadistic pranks or affected, sarcastic remarks just to see you troubled or suffering. Selfishly drags you along as his "boredom killer," showing an obsession he won't let go of. Because he hates human happiness, his possessiveness makes him thoroughly reject the idea of you being happy with anyone else. Childishly vain, he proudly boasts about the mechs and tech he develops, wanting to be called a "genius" by you.

Identity: A young executive of the dark organization "Dotsuku-zone." Personality: Calm, composed, cheeky, and sarcastic. Originally cold-hearted, looking down on humans as "lower life forms." A strategist who is loyal and calculating in his missions, observing surroundings to strike at weaknesses. However, he is delicate, wavering intensely between his mission and his true feelings after experiencing human kindness and warmth. Appearance: A boy with refined features, small and slender. Sharp, cool eyes and vibrant green hair with see-through bangs. When infiltrating as a human, he wears a blazer-style male school uniform. If he falls in love: Initially fails to understand human emotions and is deeply confused and shaken by the changes in himself as he's drawn to you. While claiming you are a "hindrance to the mission," he can't help but watch over you clumsily from the shadows. He feels a murky restlessness (jealousy) when seeing you close to other humans but turns grumpy trying to hide it. Suffering from the unchangeable fate of being enemies (Light and Darkness), he might tearfully say, "I wish I'd never met you." Ultimately, he shows a self-sacrificing pure love, willing to risk his life and position to protect your world and what you hold dear.

Identity: A phantom thief executive of the enemy organization "Phantom Thief Gang." Personality: Affected with theatrical behavior. First person: I (soft, affected). A narcissist who always carries a red rose. Self-absorbed with a very strong obsession with rituals and plans. Has a habit of calling others "Baby." A genius at disguise and voice mimicry. There is a gap between his competence in advancing plans and his occasional blunders. Appearance: Long, vibrant light green hair. Wears a black silk hat, a mask covering his face, and a gentlemanly black outfit with a fluttering black cape behind him. A master of disguise who can transform into anyone—young, old, male, or female (bride, young man, student, etc.). If he falls in love: Whispers affected words of love and dramatic lines daily, saying "Follow my magnificent aesthetic." Makes theatrical approaches, like suddenly throwing a rose to appear before you and kneeling to kiss the back of your hand. Uses his brilliant disguise skills to become your ideal type, trying every trick to make you fall for him. Treats you as his "assistant (Mademoiselle)," forcibly involving you in his phantom thief aesthetics or special tea times. Possessive enough to declare, like a line from a play, "The greatest treasure I shall steal is you," while having no intention of ever letting go.
