User blog comment:Ssj4jw/Will there be a Second Season?/@comment-25286645-20151220205800

Ah... Chaos Dragon isn't based off a JRPG, it's based of a six-day tabletop RPG session by various famous 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), which created enough material for a seven volume light novel series which ended up getting two manga adaptions and an anime adaption.

Anyway, to answer your question, I don't think the anime will get a second season, considering the amount of people dissatified with the adaption, even if you look at the MAL review, they all score it value ranging from 2 to 4, which shows something to say the least. Most people are disappointed with the skipping of major points of character development and other scenes. Altogether, the public opinion seems fairly negative which mean that Chaos Dragon probably isn't going to get a second season.
