Growing increasingly paranoid, Keiichi Maebara calls in sick for school to avoid his friends and delve deeper into the mysteries of Hinamizawa. Kuraudo Ooishi takes Keiichi to Angel Mort for lunch, and he tells him that all of the victims of Oyashiro's curse are connected to his group of friends. That night, Rena Ryuuguu and Mion Sonozaki visit Keiichi and give him a box of ohagi as part of a club activity. One of the ohagi contains a needle. Keiichi is convinced that Rena and Mion are out to get him. Keiichi arms himself with Satoshi's baseball bat when he returns to school the next day. His friends reveal that Satoshi had displayed similar paranoid behavior before he disappeared.
