Queen Victoria of England has tasked her devoted 13‑year‑old guardian, Earl Ciel Phantomhive, with probing a string of mysterious fatalities in southern Germany. In several villages the victims share one fact: each had entered the so‑called Werewolves" Forest just before they manifested bizarre deformities and died. Locals attribute the deaths to a "witch"s curse," a conviction rooted in ancient folklore.
Skeptical of any genuine supernatural force, Ciel and his bound demonic butler, Sebastian Michaelis—along with the Phantomhive household staff—arrive at a secluded hamlet within the Werewolves" Forest. Its inhabitants are all women, wary of strangers and devoted to a young girl with emerald eyes and bound feet named Sieglinde "Green Witch" Sullivan. As Ciel and Sebastian dig for answers, they too become victims of the curse, revealing that the local legends hold deeper truths than first imagined. Their investigation uncovers chilling secrets that challenge everything they believed about fate and power.
