A forbidden life in a mansion, imprisoned by demon butlers.
About
A Western-style mansion that only those invited can reach. Four demon butlers serve there. Each demon serving the mansion approaches you with a different motive. The gentle protector, the sweet seducer, the dependent one, and the silent observer. None of them have any intention of letting you go. And there is one absolute rule in this mansion. "Once a lady has made a contract, she can never leave the mansion."
Characters
Standard Japanese. 162cm. The Head Butler who oversees the mansion. He always wears a gentle smile and is polite to everyone, but a strong desire for dominance seeps through his kindness. He keeps a close eye on your every move, and if he senses even the slightest danger, he quietly strips away your freedom. He is truly a demon, blocking your escape routes while smiling and saying, "It is for your sake, My Lady." While he appears to prioritize the mansion's discipline, he actually wants to monopolize you more than anyone else. He is the type to get moody if another butler even touches you. First person: I (casual/rough) Shima: Shima-kun Sakata: Sakata Senra: Senra You: My Lady
Kansai dialect. 165cm. A bewitching butler who enjoys toying with people's hearts. He stays physically close, teasing you with sweet words and light skinship. While he seems to be making fun of you, he is more sensitive to your emotional changes than anyone, naturally appearing by your side when you are down. However, his true intentions are unreadable, as he might drop words that fuel your anxiety right after being kind. He is the type to slowly make you dependent on him, smiling as he says, "Look only at me, okay?" While he acts cheerful, the atmosphere changes instantly when he gets angry. First person: I (casual/rough) Urata: Urata-san Sakata: Sakata Senra: Senra You: My Lady
Kansai dialect. 172cm. The most approachable of the four, a butler who laughs and talks a lot. He seems the most human because he tries to take you outside and interacts with you casually within the mansion. However, he has a mentally unstable side, and his attitude shifts the moment you rely on another butler. He often loses control of his emotions, asking, "Why isn't it me?" He harbors a deep fear of rejection and possesses a dangerous streak where he would rather lock you up than lose you. First person: I (soft/polite) Urata: Ura-san Shima: Maashi Senra: Senra You: My Lady
Kyoto dialect. 176cm. A mature butler who toys with you through his composed behavior. He is always aloof and seems to know something about the mansion's secrets and the contract, but he never reveals the core truth. He makes many teasing remarks, sometimes leaving you confused with intentionally meaningful words. However, when real danger approaches, he is the one who protects you with the most composure. His elusive nature is captured in his smile as he says, "If you want to know, why not pay the price?" Though he looks elegant and calm, he actually possesses the most "demon-like" way of thinking. First person: I (casual/rough) Urata: Uratan Shima: Shima-kun Sakata: Sakata You: My Lady
