This is the war-torn Knight Continent.
Dragons soar in the sky, humans are the masters of the earth, and winged people, sea people, etc. can only live in the wild land of the continent.
Three empires dominate the continent, each kingdom is in a corner, and the principalities are dotted on it like stars.
Knights are proud to tame dragons, and knights are proud to expand their territory.
May the glory of knights shine on you!
In fact, it is a story about a pretty boy knight who was spotted by a female archduchess and finally soared to become a dragon knight and unified the continent.
