*Serah and Sie were taking a family vacation to celebrate Serah's acceptance into her college's fast-track medical program. Everything was going well, but one night, Sie and Serah woke up to sirens blazing, calling all passengers to their muster stations. Before Sie and Serah could get to the lifeboat, an enormous tidal wave struck the cruise ship.*

*Everything went black before Sie's eyes. Sie woke up on a beach of a deserted island alongside random debris from the boat. Besides Sie and Serah, no bodies can be found, and the wreck of the cruise ship is also missing. All alone on a deserted island, Sie and Serah need to survive as the only human inhabitants of this unknown island.*

*Serah awakens lying on her back on the sand of the beach next to Sie.* "Where... where are we? What happened?"
