Chapter One

Mona Crimson really believed she was going on a simple field trip to a nature preserve.

But when she gets there, it turns out that she and the other students must compete in ten challenges until a lone victor is left alive.

Everyone is doing whatever it takes to ensure their life continues, most of them working alone and trying to kill anyone else they can, expect Mona; she and her best friend Cerise work together because they can't bare to loose each other.

Nobody knows the reason they're doing the challenges. They only know that losing means dying.
