Böcker i How a Realist Hero Rebuilt the-serien

"In the two years since the Spirit King's Curse shook the world, the Kingdom of Friedonia has prepared for impending chaos...but it's not the only one making moves. The Great Tiger Kingdom of Haan has brought to heel two more powerful countries, and now Fuuga declares war on mankind's greatest nation: the Gran Chaos Empire. Will the Kingdom abandon its ally the Empire to steer clear of Fuuga's wrath, or take up arms and risk everything?"--Provided by publisher.

TO THE NORTHAfter defeating the Gran Chaos Empire, the Great Tiger Kingdom becomes the dominant human nation, splitting the world in two. King Fuuga then extends an offer to his would-be enemy Souma: a joint campaign to the Demon Lord's Domain! Risky as it sounds, Souma recognizes the need to liberate the demon front and accepts. He gathers information on the mysterious demons in earnest, but when their forces go on the march, the demons seem to possess power beyond anything Souma imagined!

"When Kazuya Souma is unexpectedly transported to another world, he knows the people expect a hero. But Souma's idea of heroism is more practical than most: he wants to rebuild the flagging economy of the new land he's 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"--
