In the year 3015, the year of Huanli, two countries, Donatia and Kouran, are engaged in a war for supremacy that is tearing the world apart. The small island of Nil Kamui has been particularly hard hit by the war, with lands conquered in the name of each kingdom and stolen from the people. To make matters worse, their deity, the Red Dragon, has gone insane, rampaging through Nil Kamui, burning villages and indiscriminately killing people. Ibuki, a descendant of Nil Kamui's royal family, lives in an orphanage and refuses to be king. Ibuki, who despises conflict, wishes for a peaceful resolution, but the chaotic world will not allow for such pacifism when it is torn apart by war.
