Chaos Dragon: Sekiryuu Seneki

Plot
The story takes place during Imperial Era 3015. Donatia and Kouran, two countries fighting for supremacy over the world, are causing it to be torn apart due to the constant warfare and bloodshed. Amidst the strife, is the island country of Nil Kamui, which has lost its independence. The Red Dragon, the guardian deity of Nil Kamui, didn't protect the land though, as it had lost control of itself. Will the island country of Nil Kamui be able to regain its independence?

Chaos Dragon is based on the role-playing fiction project Red Dragon, a story which was created by five notable character designers: Gen Urobochi (Fate/Zero), Kinoko Nasu (Kara no Kyoukai), Iduki Kougyoku (Mimizuku to Yoru no Ou), Ryohgo Narita (Durarara!!), and Simadoriru (member of the Stripe Pattern doujin circle). The results of their tabletop role-playing game sessions over six days created material for a seven-volume light novel series.
