Ep. 8: Nana manipulates classmates to cover up murders while Kyoya uncovers her deception

Following Yuka's disposal, Nana encounters Kirara, who claims to have fought Kaori. Nana poisons Kirara, extracts her phone password, and tampers with Kaori's contact case. She informs Kyoya of Yuka's death and later tells the group at the cliff that Yuka committed suicide. After convincing Moguo to burn the corpses of Yuka, Shinji, and Kirara, Kyoya grows suspicious until Kaori's body is found. He discovers Kaori was poisoned through her contacts. That night, Nana, Kyoya, and Michiru return to Kaori's room, where Nana realizes an error. Michiru checks Kaori's phone, leading Kyoya to conclude Nana is the killer. He waits for classmates to arrive to explain her actions and checks Nana for Kirara's phone.
