Growing increasingly paranoid, Keiichi calls in sick for school to avoid his friends and delve deeper into the case. Oishi tells Keiichi that all victims of Oyashiro's curse are connected to his group of friends. That night, Keiichi discovers a sewing needle inside the box of ohagi, which Rena and Mion give. Fearing that they will watch him, Keiichi wields Satoshi's baseball bat, after returning to school the next day. His friends reveal that Satoshi had displayed similar paranoid behavior.
