Black Butler: Emerald Witch Arc

The Phantomhive earl, Ciel, and his butler Sebastian investigate a series of deaths in southern Germany, where the victims had all visited the Werewolves' Forest before developing strange deformities and dying. According to local folklore, the villagers blame a witch's curse. However, the Phantomhive servants soon find themselves in an isolated village within the forest, inhabited only by women, who are hostile towards outsiders. They serve a young girl named Sieglinde Sullivan, known as the Green Witch, who lives with bound feet and has striking emerald eyes.
