The year is 2013 of the Third Era. The Hannya, pale devils, rule half of Tsudao, our world, and more Dragons are vanishing day after day. But there may be hope still for all the free people of our world. And it all rests in the hands of a boy, yet to learn of his importance; a girl, lost in this world and without her home; and a fallen god, angry at the heavens and those who banished him. Can these three save Tsudao from corruption? Or will the corruption of the Hannya spread to them as well? Wait and see. ムカデの神を信じないでください。 彼は私たち全員を裏切るでしょう！
