Synopsis
Kazuya Souma is brought before the king and queen of the Elfrieden Kingdom. The king is envious of Souma being relaxed and explains that he was the target of the hero summoning. He talks about the world and how mankind if fighting against the demons that appeared 10 years ago. The Gran Chaos Empire vowed to fight them but required compensation from the nations that didn't border the Demon King's Domain. They were going to send him instead of funds to the Gran Chaos Empire. Souma decides to discuss what was going to happen next privately with the kin, queen and the prime minister, Marx. They discussed various topics and the king left enlightened. The next day, Souma is declared the new king of Elfrieden and is also engaged to marry Liscia Elfrieden, the king's daughter.

Liscia herself came rushing home wishing her parents were okay. She quickly learned from them that the king abdicated of his own free will. She assumed Souma was up to no good but quickly learned that he only wanted to save the kingdom to save himself. He also learned that he could use magic known as living poltergeist. He sold off some of the national treasures to pay off the debt, but also told Liscia that there were many reforms that needed to happen including limiting the acreage of cash crops that weren't cotton. He also hoped for the kingdom to grow food again and hoped Liscia to run the kingdom when he was done.

Liscia thinks about her 'failures' as a leader as they eat breakfast. There they meet the captain of the guard, Ludwin Arcs and they talk about how the three dukes (Georg Carmine, Excel Walter and Castor Vargas) have remained in their domains. Souma also wants to find better subordinates and decides to use the royal voice broadcast to help with the recruitment.

There were many individuals that took part with Valor, Beauty and Public Entertainment being the most crowded categories. Competitions were held for each being the Kingdom's Number One Fighting Tournament, Elfrieden Bishoujo Grand Prix (with some rumors floating around) and Kingdom of Talents. Five individuals who were the most exemplary stood before the king. Aisha Udgard, the dark elf, was pronounced the best when it came to combat. Souma looked over what the dark elves were with his glove and book with his living poltergeist. She wanted the king to deal with the human trespassers coming into the god protected forest. Souma says he'll do what he can because of the food shortage and suggests trading for lumber from periodic thinning. Aisha doesn't know what thinning meant but when she does, she bows in respect asking for the king to visit them to teach them the 'art of thinning.' She was made into the king's bodyguard.

Hakuya Kwonmin is next and was shown to have great knowledge. He's made into a castle librarian after rejecting the first recommendation. Gyna Doma was next as the winners of both the Elfrieden Bishoujo Grand Prix and Kingdom of Talents. Souma asks to demonstrate with a lively song, but Gyna cannot accommodate. Souma gives her a song to listen to via his music player and she remembers it. She sings the song very well and wants to hear more songs at a later time.

Next up was the mystic fox Tomoe Inui who was a refugee. She gives the fact that she can talk to demons to the king only, and he manages to keep his cool. He calls for a break and for Gyna to sing for the kingdom in the meantime. He gives the information to the others in a private room and to compensate for her new importance she's allowed to be adopted by Albert and Elisha with her old family allowed to work at the castle. When they reconvene, Poncho Panacotta is up next for his gift for gluttony and Souma is delighted. After Poncho is declared to be a retainer, Hakuya speaks up saying that he no longer wants to be a librarian but someone similar to a strategist and later the prime minister. After the big meeting, Liscia and Souma talk in the back.

As rumors of a mannequin circulate the castle as Souma mentions that his magic increased to the point where he can manipulate four inanimate objects at once. As Souma thinks about the day care that is now active in the castle, Liscia confirms that the rumors were Souma testing out his magic. In the conference room, Poncho talks about how he got the items he was looking for using the hero's bag of holding and a royal flying dragon. In the dining room, a setup is made for a cooking show to help the short-term food situation. They learn how they can make an octopus, burdock root, red bear's paw, sword tiger's liver, grilled salamander and Zelring (slimes) edible. Souma is delighted by the Zelring Udon but the locusts are an odd choice. Later Hakuya and Souma talk about the neighbors and that the Principality of Amidonia were likely going to attack them while they were at odds with the three dukes.

Eventually Hakuya tells Souma to take a day off and take Liscia and Aisha with her. Souma learns about combat while promising to visit to the god protected forest to help with the thinning. As they talk about various projects, Liscia also learns that Souma would want to marry someone for love's sake. In Gyna Doma's cafe Souma learns that he can have up to eight wives. He also meets up with Kaede Foxia and Halbert Magna and learns about Georg Carmine's intentions. Souma asks them about it and when Halbert tries to grab Souma he's held by his face, neck and back by Aisha, Liscia and Juna respectfully. After his highness is revealed, Souma reveals that he's going to take down the three duchies' without help from the Mercenary State Zem and mentions indirectly that Kaede won't be protected and Halbert needs to think about what he's fighting for. The trio leaves apologizing for the disturbance.

They meet Halbert's father, Glaive Magna, the following day who apologizes for his son's behavior and gives some news to Souma. Everyone is stunned in their own way before Kaede is promoted and Halbert is transferred to serve under him.
