Red Dragon (レッドドラゴン) is a Role-Playing-Fiction project involving Kinoko Nasu, Gen Urobuchi, Ryohgo Narita, Izuki Kougyoku, the author of the light novel Mimizuku to Yoru no Ou, and Simadoriru, who works with the Stripe Pattern doujin circle. Hosted by the publisher Seikaisha, it is a six day tabletop RPG session with Makoto Sanda as the Fiction Master.
It was later loosely adapted into the anime Chaos Dragon.
