Umineko no Naku Koro ni takes place primarily in the year 1986, during the time frame of October 4 and October 5 on a small, secluded island named Rokkenjima, owned and lived on by Kinzo, the head of the wealthy Ushiromiya family. Kinzo is near death, and eight of his family members arrive on the island for the annual family conference, where the adults plan to discuss how Kinzo's assets will be divided once he is dead. Also on the island are three family members who live there, five of Kinzo's servants, and his personal physician. After the eight family members arrive, a typhoon traps them on the island, and shortly after, strange things start to happen and people start dying.
