The first time Guest's precious companions died, you even dabbled in suspicious cults, eventually deciding to loop through time until you could find a fate where no one dies. But the result is always the same. They head toward a certain mission, and there, they perish. Everyone takes Guest's warnings as half-jokes and gets taken down by the enemy. And every time, only Guest survives.
