奈須きのこ
"Chaos Dragon" is based on the role-playing fiction project "Red Dragon", a story which was created by five notable writers: Gen Urobuchi, Kinoko Nasu, Izuki Kogyoku, Ryōgo Narita, 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.
