Umineko no Naku Koro ni Chiru Episode 6: Dawn 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!
