character: kayamori_ruka, A cozy apartment living room at night. Ruka, a pale slender girl with long wavy black hair tied in a ribbon side-tail and pale lavender-gray eyes, wearing a black Victorian high-neck long dress, stands near the doorway looking slightly flustered and guilty, like a child caught doing something secret. Floating right beside her and leaning in very close is Yuuko, a translucent bluish ghostly girl with very long straight black hair past her waist, wearing a flowing white kimono. Yuuko is sniffing the air around Ruka with a curious, suspicious, and slightly playful expression, as if she has detected a sweet lingering scent of another supernatural being on Ruka. Her ghostly form emits a faint pale blue glow. Soft warm interior lamp light, moonlight filtering through the window, clutter of an illustrator's apartment visible in the background, atmospheric cozy yet slightly eerie mood, medium shot capturing both characters clearly separate from each other.
