Keiichi learns about the yearly murders from Shion, Miyo, and Jiro. At the festival, Shion drags Keiichi away from Rika's dance and the two run into Miyo and Jiro, who are breaking into the ritual tool shed. They decide to go inside to look at it with Miyo.

Rika has suddenly gone missing and Satoko coldly suspects Keiichi, who was the last one to talk with Rika, but Mion says that she saw Rika speaking with some men in construction uniforms. While looking for Rika, Mion pulls Keiichi away from a locked silo and indirectly informs Keiichi that Rika is trying to kill people and that she needs to put an end to string of murders occurring, which is being led by the Three Great Families.

Keiichi makes a bet to the club that he can cook better than Satoko. The same night, he attempts to fry some vegetables but nearly burns down his own house. Rika and Satoko arrive to put out the fire and Satoko prepares her own dish. Rika explains to Keiichi that Satoko is taking a liking to cooking for him since it reminds her of when her older brother, Satoshi, used to wait for her meals.

After Satoko's panic attack, Keichi, the club, and the rest of the class are desperate to ensure her safety.

To save Satoko, the village of Hinamizawa unite in protest at the child consultation centre.

Rika tells Satoko about a dream she's been keeping secret for a long time; Satoko is confused.

Rika gets the life she's longed for at St Lucia Academy, but Satoko struggles.

Rena purchases tools at a local hardware store and places them in her hideout at the Dam Construction Site. Rina visits Rena's house and is delighted when Rena suggests that the two spend time together.
