Finally a non western government. I'm a bit tired of all the medieval fantasy novels having an imaginary European-type government.
I find it curious that the proof of his Lordship, is a sword. In European countries like Spain sometimes " Royal public-servants" had a "Bastón de mando-sceptre of command". The certificate with the title given by the King, was supposedly rolled up into the spectre.
I didn't understand it in the LN and I don't understand it in the manga. How on earth did he think that the change of the noble owner of a territory could be done by a simple civil servant?.
