Umineko: Letter to the Golden Witch

When Dlanor A. Knox, head inquisitor of Eiserne Jungfrau, stumbles upon a mysterious game piece from the Rokkenjima game board, she sets out for the Golden Land to deliver it to Beatrice in person. Upon summoning, the piece transforms into Etna Alighieri, a young woman with no apparent ties to Rokkenjima or to Beatrice—merely the furniture of a witch whose name she has forgotten. Can Etna fulfill the task left by her long-lost master? Can the bond between them ever be mended, or is she destined to vanish forever?
