Umineko When They Cry Episode 7: Requiem of the Golden Witch

Battler assumes control of the sixth game, wielding his new golden truth as he parries the logical blows of the detective-and-witch, Erika Furudo. For Battler, what began as a contest over the existence of magic has become a fight to revive the fiery, vibrant Beatrice of his early clashes on the game board. The logical loops and rules of the game were already complex, but now as the game master, Battler must quickly learn how to shape the events to his and Beatrice's ultimate ends without getting locked in a closed room by Erika, the Witch of Truth!

Lambdadelta takes over as Game Master following Beatrice's defeat at the end of the previous arc while Bernkastel takes primary control of the human side in the game. Battler meanwhile tries to understand the truth behind Beato's games and comes into conflict with Erika Furudo, a detective character created by Bern who approaches the island murders from a "mystery" perspective, in contrast to Battler's "anti-fantasy" stance. The chapter also has a focus on Natsuhi, who receives threatening phone calls from a "Man from 19 Years Ago".

This episode presents an alternate reality where Battler does not come to Rokkenjima, the Golden Witch does not exist, and a mysterious child named Lion is now the designated successor to the Ushiromiya family. The detective Willard H. Wright is tasked by Bernkastel to investigate this strange world and uncover the truth behind Beatrice. The chapter delves into the past experiences of several characters, including Kinzo and the person who would become Beatrice.
