Umineko no Naku Koro ni Timeline (final game)

The final game is a relatively simplistic puzzle created by Bernkastel as a challenge to BATTLER. The final game is specifically designed so that magical influence is impossible, thus eliminating the usual challenge of trying to disprove the existence of magic. Instead, the goal of the game is simply to find the culprit.

The Rokkenjima masssacre
In this timeline, Kinzo never appears, presumably following the assumption that Kinzo is dead prior to the beginning of a Game. In the first twilight, Eva, Hideyoshi, Rosa and Genji are all killed in the Ushiromiya family dining hall. Kyrie and Rudolf are seemingly killed, however, their deaths are faked and the confirmation of their death is done by Battler, and is also false. The group then proceeds to kill Krauss and Natsuhi in Natsuhi's room in the second twilight. In the fourth twilight, they kill Shannon, thus also "killing" Kanon. In the fifth and sixth twilights, the group kills Gohda and Kumasawwa. In the seventh twilight, they kill Doctor Nanjo in the guest house. For the eight twilight, Kyrie and Rudolf kill Jessica outside the guesthouse. As the remaining group of Battler, George and Maria despair over their losses, George begins to seriously question who the culprit might be. However, George stops himself from thinking about it once we realizes that one of the cousins must be implicit in the murders. Maria, however, glibly speaks her mind on the topic of the culprit and comes to the conclusion that Kyrie, Rudolf and Battler all worked together to slaughter the family. Acknowledging her deduction, Kyrie and Rudolf emerge from a few bushes and declare that they in fact are the killers. Battler joins his parents as they kill George and Maria. The family laughs as an otherworldly Ange looks on, helpless.
