character: hong_meiling, patchouli_knowledge, koakuma, rumia. A medium shot from a wide angle captures the grand library of the Scarlet Devil Mansion, where towering bookshelves vanish into the shadows. In the middle-left foreground, rumia, a blonde girl with short hair and red eyes, looks up in awe with her mouth slightly open, pointing her finger toward the high shelves. Beside her, koakuma floats with her bat wings spread, leaning in with an enthusiastic smile while pointing a hand toward a specific book section. In the distant right background, patchouli_knowledge, with long purple hair and wearing a pink and purple striped dress, sits at a massive wooden desk piled with grimoires, focused intently on a spellbook. In the mid-ground near the entrance, hong_meiling stands with red twin braids and a gentle smile, watching the others. The scene is lit by warm candlelight and floating magical orbs, casting dancing shadows on the wooden floors. The visual style is a traditional croquis aesthetic with visible paper texture, soft sketchy strokes, and warm muted tones, creating a cozy yet mysterious atmosphere.
