Plot

"O, Hero!"

With that cliched line, Kazuya Sōma found himself summoned to another world and his adventure--did not begin. After he presents his plan to strengthen the country economically and militarily, the king cedes the throne to him and Souma finds himself saddled with ruling the nation! What's more, he's betrothed to the king's daughter now...?! In order to get the country back on its feet, Kazuya calls the wise, the talented, and the gifted to his side. Five people gather before the newly crowned Souma. Just what are the many talents and abilities they possess...?! What path will his outlook as a realist take Kazuya and the people of his country down? A revolutionary transferred-to-another-world administrative fantasy series starts here!

Characters

Main Characters

Kazuya Souma (相馬 一也, Sōma Kazuya)

Summoned to another world to reportedly deal with the threat of the Demon Lord's Domain, Kazuya instead finds himself with the throne of the Kingdom of Elfrieden and the hand of Liscia Elfrieden thrown at him. Now king, Kazuya begins radical reforms in order to improve the standard of living in the kingdom. In the One Week War, Kazuya finds himself in a civil war between himself and Dukes Georg Carmine and Castor Vargas while also having to fight the Principality of Amidonia. Through a series of military strategies, Kazuya emerges victorious and annexes Amidonia, although this was entirely unplanned to create the Unified Kingdom of Elfrieden and Amidonia, otherwise known as the Kingdom of Friedonia. He then forges a secret alliance with the Empress Maria Euphoria of the Gran Chaos Empire.

Liscia Elfrieden (リーシア・エルフリーデン, Rīshia Erufurīden)

The crown princess of the Elfriedon Kingdom and Kazuya's first fiancée, Liscia was at Kazuya's side from the very beginning. Initially dissatisfied with the unannounced engagement, Liscia soon softens and eventually develops deep feelings for Kazuya. Following the end of the One Week War, both Kazuya and Liscia affirm their love for each other, which results with the beginning of a series of nightly activities. Liscia is extremely tolerant of Kazuya's philandering, even encouraging him to take more wives.

Aisha Udgard (アイーシャ・ウドガルド, Aīsha Udogarudo)

Daughter of the Chief of the Dark Elves of the God Protected Forest, Aisha Udgard is one of the 5 people discovered during the gathering of the Gifted People, the first policy Kazuya implemented as king. She serves as Kazuya's bodyguard and falls deeply in love with him during the landslide incident that struck her home. Following the One Week War, Aisha becomes Kazuya's second fiancée in recognition for her actions in that war concerning the hostile Principality of Amidonia. She is an utter glutton and Kazuya himself thinks of her as a cute pet.

Juna Doma (ジュナ・ドーマ, Juna Dōma)

Also known as Lady Canaria of the Elfrieden Navy's Marine force, Juna Doma is the granddaughter of Duchess Excel Walters who was sent to spy on Souma when he was first announced as the new King. She is one of the 5 people discovered during the gathering of the Gifted People. She primarily aids Kazuya in both war and in peace by being the Prima Lorelei, Kazuya's implementation of the concept of the Japanese idol. After falling in love with Kazuya, she is secretly made into his fourth fiancée with the reason for withholding the fact of their betrothal is the possibility of starting riots when the common folk find out that the famous idol is being wed.

Roroa Amidonia (ロロア・アミドニア, Roroa Amidonia)

The princess of the former Principality of Amidonia, Roroa Amidonia's craftiness had forced Kazuya to not only take her as his third fiancée but also annex the entirety of Amidonian territory instead of just the capital in order to prevent the Turgis Republic and the Orthodox Papal State of Lunaria from getting their claws on the territory after the Principality had lost the war. She has a very keen sense for economics and heads the Silver Deer, a private company whose public face is that of her acquaintance, Sebastian Silvadia.

Poncho Panacotta (ポンチョ・パナコッタ, Poncho Panakotta)

The Minister of Agriculture and Foresty of the Elfriedon Kingdom, Poncho Panacotta is one of the 5 people discovered during the gathering of the Gifted People. Due to his vast knowledge of edible delicacies, he was a key player in ending the food shortages in the kingdom. Kazuya has given him the name of Ishizuka.

Tomoe Inui (トモエ・イヌイ, Tomoe Inui)

A member of the Mystic Wolf race and one of the 5 people discovered during the gathering of the Gifted People, Tomoe Inui possesses the rare ability to speak to all manner of beasts and animals. When it was revealed that she could speak to a demon, Kazuya immediately recognized her as extremely valuable and she was adopted by Albert and Elisha Elfrieden in order to shelter her, in the process, becoming Kazuya's sister-in-law-to-be and Liscia's adoptive sister.

Having trespassed the southwestern border of Elfrieden, Gaius laid siege to the city of Altomura. In a clever plan crafted by Kazuya, Hakuya, and Georg Carmine, Elfrieden was able to outwit Gaius, forcing him to flee back into Amidonia proper. In the subsequent battle, Kazuya himself ended Gaius's life but not before Gaius instructed his son to keep the flames of vengeance burning. Gaius's death resulted in the Elfrieden occupation of Amidonia's capital city, Van.

Julis Amidonia (ユリウス・アミドニア, Yuriusu Amidonia)

The son of Gaius and the older brother of Roroa, Julius Amidonia is the prince who hastily inherited his post from his father prior to his death. However, after negotiations with the Gran Chaos Empire ended and Julius was given back his country to govern, rebellions soon rose up.
