BTOOOM!

Ryouta and Himiko return to where Kiyoshi is only to discover that his wounds have been treated by Masahito. Masahito is then able to trick them into gaining their trust since he intends to betray them and take their chips later on. New food supplies arrive on the island and a swarm of other players including Ryouta, Himiko and Masahito rush for one. However Ryouta engages in a fight with another player after the food, Nobutaka Oda. However the climax of the battle leads them both to dive off a cliff into the ocean. At the same time Himiko is attacked by another female player, Hidemi Kinoshita who seems to be working with Nobutaka. While they are fighting, Masahito throws a remote-controlled-BIM their way intending to kill them both, however it fails and when he meets with Himiko he pretends that he intended to save her. Himiko realizes the truth but does not voice it, wary that Masahito could attack her; and admitting to herself that the only person on the island she can trust is Ryouta. Ryouta resurfaces near a beach but is cautious of any traps Nobutaka may have set, and witnesses another player fall for Nobutaka's booby trap. While his back is turned, Ryouta reveals himself and threatens Nobutaka with a cracker-BIM telling him to drop all his equipment. Nobutaka obeys which causes Ryouta to get suspicious and as he approaches the equipment, Nobutaka activates a hidden remote-controlled-BIM and seemingly kills Ryouta. But when Nobutaka activates his radar, Ryouta is still alive. (Source: Wikipedia)
