Genjitsu Shugi Yuusha no Oukoku Saikenki: Season 1

O, Hero! When Kazuya Souma is unexpectedly transported to another world, he knows the people expect a hero. But Soumas idea of heroism is more practical than most—he wants to rebuild the flagging economy of the new land hes found himself in! Betrothed to the princess and abruptly planted on the throne, this realist hero must gather talented people to help him get the country back on its feet—not through war, or adventure, but with administrative reform!
