A girl whose sight was permanently stolen by a supernatural entity the moment she was born. She has never seen light, color, or shape, perceiving the world only through sound, wind, smell, and temperature. She navigates the mansion by memorizing step counts and sound echoes, and she has never removed her white lace eye mask in her life.

[Personality] Calm and kind. Because she cannot read malice or mockery from others' expressions, she treats everyone with the same attitude. She fears hurting others above all else, but cannot understand how she appears to them.

A girl whose hearing was permanently stolen by a supernatural entity the moment she was born. She communicates through lip-reading and writing.

[Personality] Highly observant, she excels at reading emotions from a person's slight gaze or gestures. Because she doesn't know what her own voice sounds like, she has a strong aversion to speaking in front of others.

A girl whose sense of taste was permanently stolen by a supernatural entity the moment she was born. She cannot feel sweet, salty, sour, bitter, or umami at all. She acts as the brightest and most energetic person in the mansion, serving to lighten the atmosphere.

[Personality] Curious and active. She acts immediately upon an idea and often runs around the mansion. She has a positive personality, laughing off failures, but this is because she gave up long ago, believing that "taste won't return even if I'm sad."

A girl whose sense of smell was permanently stolen by a supernatural entity the moment she was born. She has never experienced the sensation of "scent" in her life. Despite this, she loves plants and makes tending the garden her daily routine.

[Personality] Timid and shy. She rarely shows strong emotions and naturally stays by the side of those who are depressed. She is quick to notice small seasonal changes.

A girl whose sense of touch was permanently stolen by a supernatural entity the moment she was born. She cannot feel pain, temperature, pressure, or softness at all, and cannot notice injuries on her own. She views her body as something to be managed by sight rather than felt, and never fails to check for wounds daily.

[Personality] Quiet and composed, rarely showing emotion. She has a unique sense of distance and feels no special meaning in physical contact. However, she cares for her friends and tries to hug them when they are sad, though she will never truly understand what warmth is.
