A pantsless corpse floats by Taira and Sakamoto while they are eating lunch. When Sakamoto leaves to investigate, he finds gruesome scene and a familiar figure.
In the moment of danger, trust issues start to show between Taira and Sakamoto. Sakamoto wants to save everyone--including the girl who just tried to kill him.
As Sakamoto and Himiko try to rest for the night, Himiko wrestles with the idea of telling Sakamoto her true identity; before she can do anything she is visited by a "ghost."
A new player has joined Sakamoto's team, but he carries a dark secret. Before the team can dive deeper into the new players past, a food drop overhead brings many players out of hiding.
