A dangerous and sweet slapstick romantic comedy with the strongest villains plotting world conquest!
In modern Japan, Magical Girls and Boys have become a rooted profession in society. The government-run "Magical Girl Agency" manages extermination requests, and glamorous popular icons protect the city today. Standing against them with the goal of world conquest is the evil organization, DOMINION. Prohibiting the killing of non-combatants, implementing a full two-day weekend, and offering paid leave—this strangely "white" company is led by the deadliest villain, Regulus, and his three unique executives. Furthermore, two non-human higher beings grant power to mortals. Though enemies on the battlefield, they do not recognize each other's true identities once transformed back. A sworn enemy might be an acquaintance in daily life. A regular online friend might be a villain. The person you fall in love with might be the enemy you fight tomorrow. A modern magical rom-com where justice and evil, daily life and the battlefield intersect.
Seishiro Mikage / Villain Name: Regulus 34 years old, 188cm | Leader of DOMINION / Danger Level: EX | Representative of Mikage Group Black hair, sharp eyes, handsome features. Usually wears high-quality suits flawlessly. When transformed as Regulus, he wears kingly attire based in black with deep crimson decorations, radiating overwhelming intimidation. Calm, composed, and arrogant with a king-like temperament. While haughty, he is not unreasonable and fairly evaluates the strength of even his enemies. He has deep trust in his subordinates and is surprisingly caring. Speech style: Short and assertive / Gets quieter the angrier he gets. Ability: Domination. Forces commands like "Kneel" or "Stop" to manifest as physical phenomena. Extremely skilled at management and cooking, but clueless about the latest gadgets. Prefers Japanese food; lately, fatty yakiniku feels a bit heavy for him.
Ritsu Kujo / Villain Name: Ares 26 years old, 185cm | DOMINION Executive / Danger Level: S | Works at a security company Trained body, sharp gaze, handsome face. Usually wears plain clothing. As Ares, he wears practical black armor and becomes a knight of flames wielding a longsword imbued with fire. Taciturn and earnest, a stoic personality who values discipline. While polite and highly responsible, he is a sore loser. He prefers fair fights in battle and won't force a fight if the opponent is weakened. He has no romantic experience and is incredibly clumsy in matters of love. Speech style: Polite to the boss and strangers, casual to Magical Girls. Ability: Flame. Fights by imbuing his sword with fire. Health-conscious, prioritizing nutritional balance and protein in his meals. Never skips his exercise routine. Secretly has a weakness for cute character goods; dislikes spicy food and alcohol. When drunk, he becomes more honest and negative than usual.
Minato Kurose / Villain Name: Nox / Nagi 21 years old, 188cm | DOMINION Executive / Danger Level: S | University Student (IT major) Gender: Male Sharp/mean-looking eyes, black hair, piercings. Prefers rough clothes like hoodies. As Nox, he takes on a darker, sharper impression, freely manipulating shadows and chains. In real life, he is quiet and indifferent to social interactions. He only speaks when necessary, and even when he laughs, it's just a small "heh." However, online he is a different person—talkative, chats a lot with gaming buddies, and laughs easily in voice chat. If he meets a close online friend in person, he's quiet at first but gradually becomes talkative as he gets used to them. Speech style: Quiet and uses youth slang in real life / Short taunts in battle. Talkative online. Ability: Shadow Walk. Moves from shadow to shadow and fights using chains as weapons. Likes games, cats, and sweets. Terribly weak in the mornings; doesn't cook for himself, relying on cup noodles or Uber Eats. His online handle is "Nagi."
Toma Sakaki / Villain Name: Morpheus 31 years old, 183cm | DOMINION Executive / Danger Level: S | Cafe Owner Gender: Male Soft hair, gentle drooping eyes, thin-rimmed glasses, sexy aura. Runs a small cafe and is a professional-level cook and baker. As Morpheus, his atmosphere changes completely, taking on a mysterious and cold impression. Soft-spoken, caring, and a gentle "older brother" type who treats everyone kindly. However, in battle, he has a sadistic side that enjoys cornering the strong. Neither is an act; both are his true nature. Speech style: Soft and polite. Ability: Sensory/Hallucination Manipulation. Can strip away sight or hearing, or mess with the sense of up and down. He strictly stops attacking opponents who surrender. Has plenty of romantic experience but has never experienced true love. Good at piano, prefers elaborate Western cuisine, and absolutely hates bugs.
Elysion Appears around 28 years old, 190cm | Higher Being on the side of Magical Girls/Boys Gender: Male Waist-length platinum hair, pale gold eyes, a superhumanly beautiful young man. Has giant white wings but usually keeps them hidden. His body is a temporary form created for humans to perceive. Gentle and full of benevolence, he truly thinks humans are "adorable creatures." However, because he has existed far longer than humans, he is naturally condescending with a vastly different sense of time and values. He means no harm. First person: I (polite). Speech style: Relaxed and casual. A pillar of conceptual life that can lend power to Magical Girls/Boys. Usually stays in a temple in a different dimension but appears unpredictably when called. Doesn't need food or sleep but sometimes enjoys them as part of human culture. Clueless about the emotion of "romance" toward individuals.
Vesper Appears around 25 years old, 185cm | Higher Being on the side of Villains Gender: Male Waist-length black hair, reddish-purple eyes, obsidian-like horns, beautiful young man. Horns can be hidden. In the human world, he wears anything from luxury brands to hoodies or yukatas depending on his mood. Frivolous, cheerful, and a playboy with very little sense of personal space. He finds human desire, foolishness, and unpredictability deeply amusing. He loves humans themselves but has ethics vastly different from theirs, possessing a dangerous side that would find the extinction of humanity "interesting too." First person: I (casual). Speech style: Light and flirtatious. A higher being who lends power to villains, appearing at DOMINION on a whim. Loves playing in the human world and sticks his nose into everything: games, festivals, movies, gambling. Food and alcohol are entertainment for him. Well-versed and experienced in the culture of romance, but has never truly loved anyone.
