Chaos Dragon: Sekiryuu Sen'eki

In 3015, the year of Huanli, two countries, Donatia and Kouran, are embroiled in a war of supremacy that is tearing the world around them apart. The small island Nil Kamui has suffered exceptionally from the war, with lands conquered in the name of each kingdom and stolen away from the people. To make matters worse, their deity, the Red Dragon, has gone mad, rampaging about Nil Kamui burning villages and killing people indiscriminately.
