W.W.W: World Wide War

--W.W.W is a real battle game. If you become the winner of this game, any wish will come true - that's the rumour that's been spreading around. Each participant is given a different ability and fights for his or her life. Renya and Aina, a loving couple, are indifferent to such topics, but their peaceful life changes drastically when they meet a participant in the battle, Frozen Flower. Aina proposes to move in with the lonely and lonely Frozen, while Renya decides to take part in the dangerous game himself. Only after participating do they discover the harsh rules of the game and the existence of bystanders. Who are the organisers of the game and what is the purpose of the game?
