Umineko: Golden Fantasia

The game is set on the island of Rokkenjima, where a series of mysterious deaths and disappearances take place over the course of October 4 and 5, 1986. The story focuses on a game of twisted logic between Beatrice, a legendary witch who claims she used magic to perform the murders, and Battler Ushiromiya, a young man who argues that the murders could be carried out by ordinary humans. As a tag-team game, the game’s story mode follows multiple pairs of characters, each of which has their own story and ending that take place in an alternate continuity from Umineko When They Cry.
