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?

Kirai (otherwise known as 'Hate' for the meaning of her name) is a lonely 15 year old girl who lived on Destiny Islands with Sora, Riku and Kairi before their adventure began. Now, she's alone, nobody else on the Islands really talks to her. Kirai thinks that nobody is there for her to fulfill her dreams of sharing a Paopu fruit with someone special until a boy washes up on the shores of the Islands, memory gone, past erased. Kirai then sets out on her own adventure to recover the boy's memory, realizing her feelings towards him along the way.
