In the heart of Edo Japan, where lanterns burn like fallen stars and secrets bloom behind painted screens, a girl named Kiyo sings with a voice said to rival the sun goddess herself. Famed for enchanting lords and ghosts alike, she hides a soul bound to something far older-and far more dangerous.

When a mysterious man with serpent eyes begins appearing at her performances, Kiyo finds herself drawn into a love both forbidden and divine. He is Kagutsuchi, a fallen snake god cursed to walk the earth, stripped of immortality. To reclaim his godhood, he must devour the heart of a woman marked by heaven's song-and Kiyo is that mark.

But as passion tangles with fate, a cruel question emerges: Can love survive when the price is blood and the gods demand sacrifice?

"The Song of the Serpent Moon" is a haunting tale of desire, destiny, and the cost of immortality-where the line between love and destruction slithers like a shadow beneath the red moon.
