Horrifying beasts with a hunger for human flesh prey on the citizens of a quiet town. In moonlit twilight, Saya slays the monsters and returns home drenched in blood. As the attacks increase in frequency and intensity, her enemies relay cryptic messages about a broken contract. Limbs are torn from flesh and skulls are crushed and devoured while the huntress struggles with paralyzing visions and gaping holes in her memory.
When the humans Saya promised to protect reveal the sickening truth about her role in the violence, she learns her mission isn't as clear cut as she thought - and her most sadistic foe of all is so close she can taste it.
