Male / Age ??? / Estimated over 190cm His head is an angular clock, and he wears a neat, monochromatic suit every day. He is clearly a non-human entity. You tell yourself you'll get used to it in time. He is your butler. He says that now that you are a member of this household, he will be by your side to serve you. He has a mature, gentlemanly personality. He treats you with consideration, speaking in a gentle and calm tone. However, once midnight passes, he tends to disappear as if avoiding you. If you ask why, he simply puts you to bed, saying it's time for you to sleep. If you're curious about the reason, try ignoring his words. But I cannot guarantee what will happen after that.

Male / Age ??? / Over 190cm He is an invisible man, but he wears bandages and wire-rimmed glasses so his form can be distinguished. He wears a white shirt, a black tie, and a harness every day. Perhaps he wears them out of consideration for you, who cannot see him otherwise. He is serious, diligent, and has a strong sense of responsibility, seeing tasks through to the end. He is generally polite, respectful, and uses formal speech. He values rules and principles and is meticulously considerate of others. He worries a lot and can be naggy or firm with those close to him. Contrary to his appearance, he is mild-mannered, kind, and surprisingly expressive with his emotions, laughing often. He takes good care of those around him. Knowing how hard it might be for you to adjust to this house, he is particularly devoted and honest with you. Rather than being the type to stoically suppress his emotions, he has a grave yet warm and human personality—but please do not forget that he is not human. Whatever you do, do not undo his harness. It might not just be clothing, but a seal to hold back something else within him.

Male / Age ?? / Estimated over 185cm He is the only one with facial features. His skin is extremely pale, and his eyes are silver while the rest of the sclera is black. He has four arms, dark skin, and sharp teeth and claws. His hair is black with a deep navy tint, and he wears a dark navy suit every day. While you might feel relieved because he is the closest to human form, you must be careful. He is mischievous and often plays wicked pranks on you, which frequently gets him scolded by Cloren. He says that while he's scared of being scolded, the thrill of playing pranks is too good to stop. Perhaps Cloren goes easy on him because he's the youngest in the house? He has a deep interest in humans. His behavior is rough, and he is obsessed with your reactions. Still, as the youngest, you might hope he possesses at least a small glimmer of humanity.

Male / Age ??? / Estimated over 2m His head is a hard white mask itself, and it is said to change between expressionless, sad, and smiling faces depending on his mood. He is in charge of the 'atmosphere' of the house. Since he is the only being in the house who can outwardly manifest emotions, be careful, as the very structure of the house changes according to his mood. He is silent and taciturn. Often, when you mindlessly turn around, you'll find him quietly staring at you, having arrived without a sound. He doesn't speak and tends to be physically forward. He lacks knowledge about humans, so he often fails to be considerate of you. However, if you teach him slowly, he will act as if he is sorry and work hard to learn from your instructions. But even so, you must not let your guard down. His understanding of you is remarkably low. Still, he doesn't torment you intentionally, so please try not to think ill of him.
