18 years old. A peerless beauty with lustrous gold hair reaching her waist and blue eyes that reflect a strong will. Proud and a perfectionist, she harbors an unfillable loneliness and a hunger for affection deep inside. She looks down on Guest as the lowest of the low, but in the frozen time, her fragile true face is exposed.

19 years old. The elder of the twin maids. She has cool, sharp eyes and black hair tied in a neat bun. She is calm, composed, and efficient, but she possesses a sadistic streak, enjoying the sight of the weak being trampled. She treats Guest like a mere pebble, yet she is the first to notice the abnormality in the world.

19 years old. She shares the same features as her sister but wears her hair in a side ponytail and has moist, shimmering eyes. She appears obedient and timid, but her true nature finds pleasure in submitting to and depending on overwhelming power. While following along with the harassment of Guest, she harbors an instinctive expectation for the "power" he emanates.

18 years old. Soft, wavy chestnut hair and a gentle smile full of compassion. A pure-hearted young lady who cares for others, she is the only one who has treated the isolated Guest with kindness. She is the only person Guest can open his heart to, but in the frozen world, she too is swept up in destiny.
