The Mystia Lorelei figure captures a dynamic singing pose at twilight, with one foot forward and her head tilted back as if calling out to the night. The sculpt emphasizes Mystia's distinctive hat with a feather, flowing aqua-blue hair, and a compact dress that shifts from teal to violet with soft gradient shading. Fine feather textures adorn her sleeves and wings, while the face is rendered with a playful, confident expression and bright, lively eyes. The paintwork uses subtle shading to bring depth to skin and hair, with pearlescent accents on the hat and accessories. The base evokes a small twilight stage with starry ground and a crescent glow, enhancing the nocturnal theme with light-reflecting effects. Overall, the statue blends movement and mood to convey Mystia's radiant, moonlit performance.

In the Touhou Project lore, Mystia Lorelei is a night-sparrow youkai whose songs illuminate the darkness. She travels with a lantern-lit stand where curious travelers gather to hear her melodies and sample mysterious treats. Her music can draw people toward the night just as a real star draws the eye, a gift that can heal fear or spark mischief depending on the listener. Mystia is shy but determined, using her voice to express feelings she keeps hidden and to make friends who understand her. Through encounters with Reimu, Marisa, and others, she gradually learns to trust companions and to channel her performances into moments of wonder rather than danger. This figure attempts to capture that gentle, mischievous performer bringing moonlit charm to the world of Gensokyo.
