Students from all over awake to find themselves in a strange, hostile land, still in uniform and still in their school buildings. With no idea where they are or how they got there and only a limited supply of water and food, panic quickly spreads. Even worse, they aren't alone—and the natives are quite happy to kill them for their supplies. At Pisces, a wealthy academy, the student's rigid hierarchy brings relative order. And that's when they meet Syme, a mysterious boy who quickly schemes to take control.

Having no choice but to endure, the students are forced to make a life for themselves by themselves, with plenty of opportunity for both the vices and the blessings of human nature to rear its head.
