Sayogoromo, a high-ranking courtesan, holds court in Edo’s Yoshiwara district, an exclusive brothel enclave guarded by permits and gated entry. Whispers of supernatural phenomena swirl around her, including tales of her disembodied head drifting through night skies—a spectral mystery drawing the protagonists’ scrutiny. She enlists the protagonist to paint harrowing Buddhist hellscapes, but the artwork unwittingly incites psychological turmoil, manifesting as auditory echoes and visions of spectral demons clawing from the canvas. This crisis prompts the protagonist’s father to intervene, altering the painting with the addition of Kṣitigarbha, a guardian deity whose presence quells its haunting influence and steadies her fractured mind.

Her story intertwines themes of artistic accountability and the blurred boundaries between spiritual conviction and creative vision. Through her experiences, the narrative unveils societal structures of Edo-period Japan, illuminating the realities of women bound by rigid professions and art’s role as both mirror and remedy for mortal dread. The arc underscores art’s dual capacity to inflict anguish and offer solace, mirroring contemporary fears of supernatural forces while dissecting the ethical weight of creation.
