In Shibuya, Japan, there is a game that certain people of the dead play that none of the living can see, though it is played around them. With the cost of an entry fee, which is the thing you hold dearest to you, you play for a chance at living again. It is held by reapers who summon Noise, which are creatures biased on real animals sent to take out the many players of this game in one week. The players of this game must make a pact with a partner and slay the Noise to stay alive for their chance at a new life. For Galaxy, one of the newer players, this seems like an impossible task, until she becomes partners with Atmos, a headstrong, not that talkative boy who seems to hate Galaxy. Will they put aside their differences and fight together for a new life? Or will they be doomed to erasure by the mysterious Reapers and their Noise?
