13

Rika and Satoko's friends leave the house to the officers for the night. As Satoko sleeps, Rika talks with Hanyuu about Rika's fated death. Meanwhile the Yamainu disable the guards at Rika's house and infiltrate the residence, but Rika and Satoko escape. Rika and Satoko are cornered by the Yamainu in the forest at one point, but Mion, Shion, Rena, and Keiichi come to rescue them when Rena had a suspicion that 'people' were watching them after they had left Rika's house. The six of them try to make their escape to the Sonozaki household but Keiichi is suddenly shot by Takano-san standing from afar. One by one the members of the group are shot and killed by Takano-san and the Yamainu, leaving Rika for last. Rika asks Takano-san to kill her without anesthesia in an attempt to carve the identity of the culprit behind all the Hinamizawa murders into her mind and thus prevent the events from this and past worlds from repeating themselves. Rika is killed and gutted. The spirits of the group members as well as Hanyuu meet and agree that Hanyuu too must have the will to break the cycle of death. Meanwhile the villagers are rounded up at the school and gassed to death, while an ecstatic Takano proclaims her ascension to godhood. (Source: Wikipedia)
