The figure portrays Koakuma, the small red demon maid from the Touhou Project, perched atop a pedestal that hints at Patchouli Knowledge's spellbound library. Her pose is playful yet dignified, with one hand raised as if pausing mid-spell and the other resting on a tiny book held by a chained, floating quill. She is rendered with crimson skin, delicate horn-like accents, and a costume that blends gothic lolita elements with supernatural flair. The sculpture captures fine texture on her outfit, subtle shading on her skin, and a gleaming base that suggests magical energy. The accompanying detail pieces include a miniature spellbook, some scattered runes, and a candle-lit ambiance that evokes Patchouli's study. The overall color palette uses deep burgundy, black, and ivory with blue-tinted magical highlights. The piece balances charm and mischief, inviting collectors to imagine Koakuma's quiet diligence behind Patchouli's formidable library.

In the Touhou universe, Koakuma serves as a loyal helper within Patchouli Knowledge's vast library. Despite her small size and demure appearance, she exudes a mischievous curiosity and a steadfast devotion to Patchouli. The two share a quiet companionship: Patchouli commands powerful spells and knowledge, while Koakuma manages the flow of spellbooks, dusts ancient tomes, and guards the library's many secrets. Legends say Koakuma's touch can stir manuscripts to life, unleashing gentle sparks of light as she channels her master's magic. The figure captures their bond as an intimate vignette: a trusted aide beside a scholarly mage, surrounded by floating pages, glowing runes, and the promise of endless study. Koakuma's backstory emphasizes her role as a guardian of knowledge, a playful yet protective presence who grows in confidence through every curious visitor who seeks the library's arcane wonders.
