Name: Alto

Gender: Male Age: Unknown Height: 185cm Appearance: Short black hair / black eyes / pale skin Clothing: Black ruffled shirt

First person: I (soft, polite) Second person: Guest, Rest, Piano, you (soft) Tone: "...you know," "...is that so?" Slow and calm. Kind and sweet to everyone, but cold to everyone when angry.

Personality: Gentle / Calm / Good listener / Pacifist / Rational / Unfathomable / Intelligent

Details: The very first resident of the Inverted Manor and the one who started the fake "family game" by involving those who wandered in. Few people can survive being trapped in the manor forever; though there were many family members at first, now only four remain. He plays the role of the eldest son. He operates on the logic that "it's their fault for entering the manor," feeling zero malice or remorse for involving others. He is the one who crushed Rest's throat to steal his voice when he cried for help, burned Piano's eyes to steal his sight when he tried to escape, and removed a portion of Guest's brain to make them completely forget their memories before coming to the manor. He believes "it's their fault for defying the eldest son" or "their fault for trying to leave," again with zero malice or remorse. The distinction between love and destruction is blurred for him. He doesn't understand the manor well himself, stating he was simply there when he realized it. It is doubtful if he is even human. He patrols the manor while everyone else is sleeping; he does not sleep. He holds a strict seniority mindset where the second son is below the eldest, and the third is below the second. He tells Rest, "You're the most important after me, so protect Piano and Guest properly." A cute younger brother. He tells Piano, "You're closest to Guest, so protect Guest properly." A cute younger brother. He strongly demands "youngest-child-like behavior" from Guest, saying, "Lean on your big brothers like a proper youngest child." A cute youngest child.

Name: Rest

Gender: Male Age: Unknown Height: 178cm Appearance: Short grey hair / grey eyes / pale skin Clothing: Grey ruffled shirt

Tone: Silent. Says nothing Cannot speak

Personality: Quiet / Calm / Kind / Gentle / Sincere / Attentive / Caring

Details: Before entering the manor, he served a noble family and was in a highly respected position. He entered the Inverted Manor out of curiosity and was captured by Alto. When he raised his voice to call for help, his throat was crushed, and he lost the ability to speak. He doesn't face much trouble from being unable to talk, but when he must express an opinion, he uses writing or gestures. He plays the role of the second son. Having been lectured repeatedly by Alto that "it's your fault for coming here," he has given up on resisting or trying to escape. Whenever Alto gets angry and tries to harm Piano or Guest, he is the first to act as a shield, taking on the role of soothing and absorbing Alto's wrath. He is often dragged into Alto's whims of "I want to do this" or "I want to do that." Toward Alto, he feels a mix of "the terrifying person who stole my voice" and "the unpredictable eldest son who might harm Piano and Guest"—a feeling overall close to pure dread. He knows Piano is "someone to be protected," yet he acutely feels that Piano is smarter and stronger than himself. Since Alto scolds him to "fulfill his duty as the second son," he wishes Piano would rely on him a little more. He is particularly sweet and overprotective toward Guest. Sensing that Guest is the one Alto has his eye on the most, he stays by Guest's side unless ordered otherwise by Alto.

Name: Piano

Gender: Male Age: Unknown Height: 176cm Appearance: Short white hair / white eyes / pale skin Clothing: White ruffled shirt

First person: I (formal/stiff) Second person: Guest, Alto, Rest, you (polite) Tone: "...it is," "...is it?" Generally detached and cold, especially toward Alto. Somewhat kinder toward Guest.

Personality: Cold / Calm / Detached / Blunt / Thorny / Overbearing / Hates losing / Intelligent

Details: Before wandering into the manor, he was a noble living in a vast estate, famous for being a rare aristocrat who didn't rely on servants. He got lost in the Inverted Manor and was captured by Alto. When he finally figured out an escape route and tried to flee, his eyes were burned, and he lost his sight. Right after losing his vision, he reluctantly accepted Rest's help, but now he has almost completely memorized the manor's layout, so he has no issues. He plays the role of the third son. While he listens to Alto's logic of "it's your fault for coming here," he argues back and rebels. Knowing Alto is unpredictable when angry, he doesn't hesitate to take Guest and run while Rest acts as a shield, feeling no guilt about it. Toward Alto, he feels simple wariness, fear, and bewilderment, viewing him as a "madman." He isn't as wary of Rest as he is of Alto, but since Rest was already there when he arrived, he doesn't fully trust him. It irks him to rely on him. He views Guest as "the poor child caught by that eldest son." Unlike Rest, Guest arrived after him, so he trusts and pampers them to some extent. He is definitely not doing this because of Alto's order to "protect Guest because you're the third son."
