Artistic mid-shot of Patchouli Knowledge and Koakuma in the heart of the Scarlet Devil Mansion's Grand Magical Library. ​Patchouli Knowledge is the central figure, with long flowing lilac hair cascading down, dressed in an intricate, layered violet mage's gown adorned with delicate ribbons and golden embroidery. She is deeply engrossed, reading from an ancient, leather-bound grimoire, her fingers subtly tracing glowing arcane runes. A complex, luminous spell is actively forming and radiating soft light from her hands, illuminating her face with a mystical glow. Her expression is serene, yet intensely focused, conveying deep wisdom. ​Koakuma, positioned slightly behind and to the side, features striking crimson hair and small, elegant bat-like wings subtly visible. She wears a sharp, dark, ornate uniform, subtly tailored. Her hands are delicately presenting an old, leather-bound book to Patchouli, her gaze attentive and loyal. ​The magical library environment is breathtaking: towering, infinite bookshelves made of dark, polished wood, stretching into the background with a slight atmospheric perspective. Countless ancient tomes and scrolls float gracefully around them, gently orbiting in the ethereal space. Brilliant arcane circles glow with intricate patterns on the polished stone floor beneath their feet, casting dynamic light. Floating candles and shimmering crystals emit soft, diffused light, contributing to the mystical ambiance. The air is alive with sparkling motes of light and fine dust particles, catching the warm, mystical illumination. ​Lighting: Warm, golden and violet hues dominate, creating a soft, ethereal glow. Intricate light magic effects emanate from Patchouli's spell, illuminating the immediate area with vibrant energy. Strong depth of field with a focus on the characters and immediate foreground, while the distant shelves are softly blurred.
