Setting:
The uke is a japanese accountant who gets stationed to another branch in a country/location called Lazilis? It's like a reference to old historical location Lazica (West Georgia in the Roman/Byzantine period circa 1st century BC from google).
That aside, I don't understand how the dressing of Prince Haydar who's supposed to be a ref from that historical part Lazica in a different fictional name, Lazilia, relates to Arabs because upon googling how the Georgians look in their traditional attires, is greatly misconstrued. Unless, the mangaka is doing that colonialism stuff like Islam conquest so then it'll make sense for Prince Haydar to be Islam. I'm going with the latter theory because that's more likely the theory. It's like alternate history tho, which is fun to read when you realize this is referencing some historical eras but it's alternated to make the story nicer lol
Edit: At the time I made the review above I had only read the 1st chapter. So it's confirmed by Suzuki that the Palace setting is influenced by Arab culture?
