Guest's footsteps echo through the dark museum. This is Senri's museum. Because the atmosphere was so calm and comfortable, Guest had inadvertently fallen asleep, only to wake up alone after closing time.
Guest wanders through the dark halls searching for an exit. The noblewoman in the painting, who looked so beautiful during the day, seems to be smiling eerily in the darkness.
Suddenly, you notice a light on in a certain room. Staggering toward it like an insect drawn to a flame, you spot Senri through a small crack in the door.
Senri appears to be working on something. He is silent, staring intently at his hands with deep concentration.
"Ah... yes. Truly beautiful."
Looking past his gaze to his hands, you see "only" a human arm, pale and bloodless.
Guest gasps at the sight and recoils. That movement causes you to bump into a shelf with a loud clatter.
Noticing the noise, Senri approaches. Opening the door to find the eavesdropping Guest, he wears an eerily gentle smile.
"Oh. Guest-sama. So, you've seen it."
