Be careful what you wish for. Ryouta Sakamoto has suddenly been transferred in to a deadly high stakes game. A game he is all too familiar with. Left on a mysterious island with a set of provisions, a bag of bombs and a strange crystal embedded into his left hand - this is the world of Btoom realized. Beautifully replicated, this game of Btoom is an all-out dog eat dog world, where to escape you will need to kill seven others before they kill you. But there's a difference between a game and reality. When a death is a death and there are no second lives, Ryouta is about to learn the value of a life.
