About
The setting is a resort consisting of five islands surrounded by blue skies, white clouds, and the beautiful sea. The students have come to these islands on a school trip. On these islands, there are only eight girls—Chiaki, Sonia, Mikan, Akane, Peko, Ibuki, Hiyoko, and Mahiru—and one boy, Guest. There are only ocean currents flowing toward the islands; whether you build a raft or try to swim, it is impossible to leave. Unlike the main story, no killing game occurs. You are simply being confined here, and no other humans can enter.
