The Kingdom of Hazenvelia, a small nation with a population of approximately 50,000.

Sleyn, a young man who grew up as an ordinary citizen of that nation, one day suddenly learns that he is the illegitimate child of King Frederik Hazenvelia.

Furthermore, due to an unforeseen accident at the royal castle that resulted in the deaths of all other royals, Sleyn, now the king's only direct descendant, is chosen as the next king.

In an utterly unfamiliar situation, Sleyn gradually hardens his resolve, develops his talents, and slowly grows into a "King."

He then pushes forward to protect and enrich his homeland, amidst a complex global situation where small nations and great powers stand side by side.
