An eerie, highly detailed depiction of Saya as she appears in Saya no Uta: a humanoid figure with an unsettling, almost porcelain complexion and elongated limbs. The sculpt captures a slender, poised silhouette with a subtle sense of motion, balancing beauty and danger. Her hair is long and jet black, rendered with glossy highlights that catch the light. The face presents an uncanny silhouette that hints at her monstrous nature without relying on explicit gore, inviting viewers to experience both allure and unease. The paintwork emphasizes contrast, with snowy skin against deep shadows and restrained crimson accents around the lips or eyes to evoke her sinister aura. The base echoes a dim, organic environment from the story, providing context without overpowering the figure. Overall, the piece communicates Saya's duality: an alluring presence bound to a nightmarish reality.

Saya no Uta follows Akihito Nagare, a shy medical student whose senses are warped after a traumatic accident that leaves his perception dramatically distorted. To him, the world appears as a nightmarish, organic landscape where most people resemble grotesque silhouettes of tissue, while Saya appears as a strangely serene and beautiful girl who seems normal by human standards. He forms a forbidden bond with her, drawn by a mix of tenderness and fear. Saya speaks softly and reveals a rational, almost human temperament, yet hides a cruel, predatory nature connected to a hidden alien origin. The story unfolds through their secret interactions and Akihito's increasingly dangerous decisions as authorities, friends, and family become entangled in a mystery about what is real and what is perceived. The novel explores themes of love, identity, and the fragility of sanity, challenging readers to question the boundaries between beauty and horror, humanity and monstrosity.
