Higurashi no Naku Koro ni Kaku: Outbreak

An unknown virus has spread in Himanizawa and in wide regions around it. Officials suspect it to be Oyashiro's curse and force quarantine around these regions. While looking for Rika to announce to the officials that she is safe and that it isn't the curse, her friends find her to be infected with the unknown virus. When security forces cut off food and water from the village the situation gets tense, as locals put the blame on outsiders like Maebara, Rena and their families and try to kill them. Though, at the end Rika is left behind, but the rest promise that they will come back for her.
