Dragonman

Dragonman live in the Rarugo Sea. They loathe humans due to their poaching.

History
Once, Dragonmen were on good terms with human world. But that was until 100 years ago, when some bad merchants started to kidnap them to use the hard dragon skin that covered their body as materials. Merchants even started to attack their villages, until this wasn't tolerated by the Dragonmen anymore and they destroyed the merchants' land. And that's why they cooperate with the Demon Army.
