It's between good and just fine. Won't exactly call it great, but far from terrible. Art is good and the plot is more interesting than I thought. The characters, aside from the king in the last one (who I think is a bit annoying) are enjoyable, and I'm quite fond of the protagonist's banter and monologue. Ending feels really abrupt though (might be axed), so you might need to read the light novel to finish this. Overall, "Yowai 5000-nen no Soushoku Dragon, Iwarenaki Jaryuu Nintei: Yada Kono Ikenie, Hito no Hanashi wo Kiite Kurenai" is a pretty solid manga that definitely deserve a much better than scorethan a 6.
