Deck Master

When monsters suddenly emerged all over the world, can you survive?
Even though Kaan has read lots of books like this, he never thought it will became reality until he met a demon in his dreams. The demon offered him a contract because he was 'weak' and he wanted to 'help' him, but Kaan didn't accept it. The demon gave him the last threat while warped darkness swallowed him. Kaan woke up he found himself in a ruined world.
As the world slowly turns into the playground of the unknown forces and the vicious monster begins to roam around to hunt any uncreaful prey, will Kaan and the people around him be able to find a way out of this madness and survive until the end?
