18

Shion finds out Satoshi has gone missing and decides to investigate further into the mysterious murders over the past four years. She meets Takano at the library. Takano tells her more about the history of Hinamizawa and its dark past. She explains that Hinamizawa used to be called Onigafuchi and that, according to the Shrine God's Sacrifice Ritual, for each victim sacrificed, there must be an equivalent number of missing people. Takano also mentions that according to the sacrifice ritual, the missing people would have to sink to the bottomless Onigafuchi marsh, which leads Shion to believe Satoshi's body might be there. After Shion's encounter with Takano, she is visited by Mion at her apartment where she learns that Mion de-nailed herself in the same spots Shion had, after she had left, because she didn't want Shion to take all the burden. The story skips ahead one year to the present right before the Wataganashi Festival. Keiichi brings back memories of Satoshi to Shion. The story further skips to forward to where Tomitake, Takano, Keiichi, and Shion enter the shrine. After the festivities, Shion is caught listening to Mion and her grandmother as they discuss the events that have transpired over Takano and police investigations. (Source: Wikipedia)
