The Touhou Project - Koakuma figure presents a playful yet elegant portrayal of the tiny demon maid. Koakuma stands with a soft, curious tilt of the hip, one hand lifted as if inviting you to peek at a favorite book, the other resting at her side. Her long red hair cascades in gentle curls around small bat-like wings, and a pair of delicate horns peeks from the fringe. She wears a petite, frilly outfit featuring a black bodice, a white ruffled apron, and a skirt with layered lace. The base evokes a library vignette, with spell book motifs and subtle shadows that suggest motion. The finish emphasizes glossy eyes and hair, crisp sculpted lines, and textured fabrics to convey charm, mischief, and warm charm.

Koakuma is a demon attendant to Patchouli Knowledge in the Scarlet Devil Mansion's library. Despite her diminutive size, she holds a keen interest in occult tomes and magical texts. She can be found organizing shelves, lending a mischievous spark to readers, and sometimes playfully misplacing books with a cheerful wink. Her aura hints at mischief, yet her loyalty and diligence show through in quiet moments when she helps Patchouli tend to rare manuscripts. Her relationship with Patchouli is one of companionship and mutual study, a dynamic that balances curiosity with restraint. In the Touhou universe, Koakuma adds warmth and mystery to the mansion's halls, suggesting knowledge can be powerful yet comforting and approachable.
