Earth is assimilated into an intergalactic game for survival, and everyone is forced to play - or die. One of the many (un)lucky participants goes by the name of Vincent. He wakes up in the middle of a forest, and the first thing he notices is that he isn't quite human anymore. His memory databank is malfunctioning, but he is aware of the fact that he just woke up in a new, dangerous world where the weak get eaten by the strong.

In which direction will his new life develop?
