1

Keiichi Maebara moves to the rural village of Hinamizawa and befriends four girls—Rena Ryuugu, Mion Sonozaki, Satoko Hojo, and Rika Furude. He joins their after-school club. Life is peaceful until Keiichi learns from a man named Tomitake about a murder in Hinamizawa's past. He also learns about a dam construction project which had been proposed by the government five years earlier. The project met with protests and was withdrawn. When Keiichi asks Rena and Mion about any incidents relating to the project, they refuse to speak about it, which makes him suspicious. He gets even more suspicious when he finds a newspaper article about the dam project manager being dismembered. He learns that one of the killers is still at large. (Source: Wikipedia)
