Higurashi No Naku Koro Ni Kai Episode 12 English Subbed Episode Title:Massacre Chapter Seven – Hinamizawa Syndrome.Episode Description:Rika tells her friends the details of the Hinamizawa Syndrome, regarding how the disease whose symptoms show up when one tries to leave the village. Rika reveals that the clinic, was actually an establishment built to research the disease, or more specifically gather information on how to harness it as a biological weapon, sponsored by various bureaucratic connections collectively referred to as "Tokyo". The Yamainu are revealed to be a security force tasked with maintaining the secrecy of such an operation. Irie is revealed to be innocent in the matter, as he was originally hired as a director of the institute but his actual intentions were to find a cure for the syndrome rather than to develop a biological weapon. Rika revealed that her family lineage has historically been referred to as "Queen Carriers" that have suppressed the onset of symptoms of the syndrome, and thus she is targeted by the military. Her friends believe her without hesitation. The police are stationed, at Rika's request, around the Furude residence to give her added protection. The military forces kill Oishi and his assistant at the radio tower.
