Spoiler Warning!! [+/-] Show/Hide Synopsis...
After listening to Teppei and Rina's conversation and checking her father's safe box, Rena realizes that Rina is out to financially ruin her family, and in turn, her happiness. Rina pursues Rena to the Hinamizawa dump site to pressure Rena into accepting her into Rena's family, but Rena vehemently objects. Then Rena reveals that she knows Rina's plan, which causes Rina to make an attempt on Rena's life. Rena manages to overpower Rina and beats her to death with a pipe. She then lures Teppei to the same place and murders him with a cleaver. The next day, Rena dismembers the bodies and cleans up the bloody mess, but Keiichi and her friends appear. They still accept Rena as their friend even after her confession. Together, they cart away the bundled pieces of Rina and Teppei's body. A few days later, the Watanagashi Festival begins, and Officer Oishi shows up with a suspicion in Rena.
