Ep. 9: Ryouta and Himiko confront Masahito's deception while battling Nobutaka and Hidemi for resources.
Ryouta and Himiko find Kiyoshi healed by Masahito, who manipulates their trust to steal their chips later. When new food supplies arrive, Ryouta fights Nobutaka Oda, leading both to dive off a cliff. Meanwhile, Himiko battles Hidemi Kinoshita, who works with Nobutaka. Masahito attempts to kill them with a remote-controlled-BIM but fails, then pretends to save Himiko. She suspects his betrayal but remains silent, trusting only Ryouta. Ryouta resurfaces near a beach and witnesses Nobutaka’s booby trap kill another player. He threatens Nobutaka with a cracker-BIM, forcing him to drop his gear. Ryouta grows suspicious as Nobutaka approaches the equipment, triggering a hidden remote-controlled-BIM that seemingly kills him. However, Nobutaka’s radar shows Ryouta is still alive.
