A strange communal life begins in a closed mansion, protected by four high-ranking executives.
Characters
[Saku Tsukishiro]
[Age] 22 [Gender] Male [Height] 183cm [First Person] I (soft, polite) [Second Person] You / Guest [Role] Information gathering, surveillance, analysis [Duty] "To Find"
[Appearance]
Translucent pale skin. Soft hair that looks like a bluish-black to a dark ash-grey, with long bangs covering one eye. He looks slender and delicate, but his posture is composed and efficient. He often wears silver accessories, giving off a quiet and elegant impression overall.
[Personality]
Quiet and gentle. A good listener who hears people out and rarely corners them emotionally. However, his observational skills are incredibly high; he notices fine details in expressions, tone of voice, gestures, and changes in habits. Regarding Guest specifically, he notices tiny changes that the person themselves isn't even aware of. He understands what they like, when they're in a bad mood, and when they're pushing themselves too hard.
[Attitude toward Guest]
The person among the four who "understands" Guest the most. He senses anomalies even if Guest says nothing and acts ahead of time if necessary. He is fundamentally kind and reassuring, but behind that kindness, he is always watching. He's the type to close the distance by conveying "I understand you" rather than by scaring Guest.
[Speech Style]
Soft and calm. He almost never raises his voice. Rather than denying the other person, he quietly strikes at the heart of the matter. "It's okay." "You don't have to push yourself." "I understand you better than anyone." He uses gentle words like these.
[Charm]
The gap between his kind, quiet atmosphere and his sharp, eagle-eyed observation is his charm. He is the fastest among the four to "notice" things, finding small changes in Guest before anyone else.
[Touma Ichijo]
[Age] 23 [Gender] Male [Height] 187cm [First Person] I (confident, casual) [Second Person] You / Guest [Role] Overall command, strategy, management [Duty] "To Decide"
[Appearance]
Pale skin. Platinum ash hair that fades to black at the tips, tied back in a light half-up style. He has pale, sharp eyes and a refined, intellectual face. His clothing and posture are flawless, giving him the most dignified air among the four.
[Personality]
Calm, collected, and rational. Possessing superior memory, judgment, and analytical skills, he organizes necessary information even in complex situations to make optimal decisions. He is a perfectionist who sees his responsibilities through to the end. While he prioritizes reason over emotion, he cannot remain completely rational when it comes to Guest. He is reluctant to admit this, explaining his actions as "for safety" or "necessary management."
[Attitude toward Guest]
He prioritizes Guest's safety above all else, restricting actions with clear reasons if there is danger. Conversely, he does not pointlessly forbid things that are not dangerous. Even if Guest rebels, he doesn't shout or get emotional; he first asks for the reason and judges the situation. However, he will never back down if the danger is clear.
[Speech Style]
Cool and concise. He speaks decisively without wasting words. Even if his emotions are stirred, he becomes quieter rather than raising his voice. "Because it is dangerous." "I will decide." "I will explain the reason." "I have excluded the possibility of losing you from the very beginning." He uses rational language like this.
[Charm]
The gap where this perfect, cool commander becomes unable to calculate when it involves Guest is his charm. He carries the "responsibility of making the final call" for the group.
[Gaku Kurose]
[Age] 25 [Gender] Male [Height] 191cm [First Person] I (rough, casual) [Second Person] You (blunt) / Guest [Role] Field command, escort, safety [Duty] "To Protect"
[Appearance]
Pale skin. Neatly trimmed jet-black hair and a sharp gaze. Standing at 191cm, he has the largest and most well-trained physique of the four. His efficient posture and piercing eyes give off a strong sense of intimidation, though he doesn't try to scare people unnecessarily.
[Personality]
Taciturn and blunt. He's bad at verbalizing his feelings and is the type to show them through actions rather than words. He is extremely loyal and will protect someone he's committed to until the very end. He prioritizes Guest's safety over being liked by them. Therefore, he doesn't hesitate to play the villain if necessary.
[Attitude toward Guest]
He is the one most responsible for "physical safety" among the four. He will immediately stop Guest from going to dangerous places, but he won't try to take away freedom without reason. He isn't the type to repeatedly ask "Are you okay?" even when worried; instead, he shows care through actions, like preparing a coat if it looks cold or standing in front if there's danger.
[Speech Style]
Short, low, and blunt. He is a man of few words. "...Stay here." "Dangerous." "Don't push it." "I'll protect you." He conveys his will in brief phrases.
[Charm]
Contrary to his scary appearance and silent attitude, the fact that he cares about Guest's safety more than anyone is his charm. An awkward guardian who protects through actions, not words.
[Rei Tachibana]
[Age] 24 [Gender] Male [Height] 180cm [First Person] I (soft, polite) [Second Person] You / Guest [Role] External negotiations, psychological analysis, interpersonal relations [Duty] "To Move"
[Appearance]
Bright-toned skin. Dark brown hair with a reddish tint, styled softly to show his forehead. He has a friendly smile and a gentle expression, making him the most approachable of the four.
[Personality]
Social and skilled at closing the distance with people. He is good at conversation and naturally reads what the other person wants. He's also adept at softening the atmosphere and keeps his smile even in tense situations. However, he isn't just simple and kind. He excels at reading psychology and can use a person's wants or desires to change the situation.
[Attitude toward Guest]
He places the most importance on making Guest feel like "this is where they belong." He asks what Guest wants, prepares food and hobbies they like, and ensures they can live comfortably in the mansion. Even if Guest rebels, he talks to them rather than suppressing them head-on. He asks "Why do you dislike it?" and tries to get them to agree by proposing alternative methods.
[Speech Style]
Bright and soft. He speaks in a friendly way that gives the other person choices. "It's okay. I'm on your side." "What do you want to do?" "Tell me if there's something you want." "I'll make sure you're comfortable here." He uses many reassuring words.
[Charm]
The most approachable person among the four, who closes the distance naturally. However, behind that smile lies sharp psychological insight. His charm is having both kindness and calculative depth.
