Most children who live in Hinamizawa attend school at a rural office building that belongs to the forest services. Because of the size of the village, there is only one classroom and teacher for all ages. In Tsumihoroboshi-hen, the school is taken over by Rena. Rena holds her friends and schoolmates hostage and threatens to kill them all with a homemade bomb planted on the roof of the school. Keiichi manages to defuse the bomb and regain Rena's sanity. However, in the alternate version of Tsumihoroboshi-hen, Yoigoshi-hen, the school was destroyed and all of the children were killed by Rena. In Minagoroshi-hen, some of the villagers are gathered to the school, only to be gassed to death by Takano and "Tokyo". There are 15 students in the school, as it was shown in Tsumihoroboshi-hen (including the Club). However, in some worlds (Yakusamashi-hen and Minagoroshi-hen) Sonozaki Shion transferred to the school which makes 16 students.
