Umineko no Naku Koro ni Chiru Episode 7: Requiem of the Golden Witch

Umineko no Naku Koro ni Chiru Episode 7: Requiem of the Golden Witch summary:

On October 1986, the members of the wealthy Ushiromiya family and a number of their servants mysteriously died. When rumours began to circulate regarding who was responsible, it was said that the Golden Witch Beatrice magically caused the tragic events to occur. To reveal the truth behind what happened, the Witch of Miracles Bernkastel presents an alternate reality where Battler Ushiromiya does not come to Rokkenjima and the Golden Witch does not exist. Instead, the mystery child who was abandoned nineteen years ago has been designated the uncontested heir to the family as Lion Ushiromiya, whose existence holds the source of everything presented thus far. To solve the mystery, Bernkastel brings Willard H. Wright, the reluctant former Head Inquisitor of the SSVD redemption agency, to the island as a detective to solve the mystery of Beatrice, including the origin of the legend of the Golden Witch and her true identity.
