Book of puppets - a Black Butler Ff - Earl Phantomhive got a new assistant, a quite special one. The chinese man has recommended him to get an author to write down his stories for the public. But Yin's first story already tells an unbelievable incident that may involve herself. How is she going to survive at the Phantomhive's mansion? Warning: Abuse, Blood, Murder, Violence I don't own any of characters of Black Butler nor any elements of it. Not historically accurate at all haha.
