Abel Yanami is a 17 year old boy living in a small town in Europe. Summer vacation already started a few weeks ago and he still didn't know what to do with his free time. One day he decided to play a new game that came out last week but as soon as he opened the game he was taken in a forest area somewhere in the world with only one black gem infront of him...What will he do to escape this forest? Will he come back to his old world?
