University student Souma is suddenly summoned as a hero to the kingdom of Elfrieden, which is facing a number of crises, both foreign and domestic. Souma confers with the king and prime minister, after which the king makes a stunning announcement.

Souma is checked for any magical powers, and puts his results to use with the administrative paperwork. Hoping to recruit more competent personnel for his staff, Souma sends out a nationwide broadcast offering prizes to the most talented in the land.

After Souma realizes the true gravity of Tomoe's ability, he ensures that it remains a secret, and that she is kept safe. Juna and Poncho host a program that shows how to prepare readily-available but unconventional ingredients during the food shortage.

Juna and Poncho close out their cooking show with their take on udon noodles. Marx steps down as prime minister, and as Hakuya fills the vacancy, he insists that Souma get some rest. Souma, Liscia, and Aisha take a tour of the castle town incognito.

While at Lorelei, Souma overhears two soldiers arguing about whether to side with or against the new king. Hakuya reviews the political situation concerning the neighboring lands with the king. Souma and Liscia discuss the nature of their engagement.

Souma dispatches his magically-controlled mascot warrior to join an adventurer party. After securing funding with his team of accountants, Souma sets out to build a new port city and network of roads, but runs into opposition from the local residents.

Kaede leads an engineering corps, including Halbert, in constructing a road. As the work detail receives a royal inspection from Souma and Liscia, an urgent message from Aisha's father arrives, informing them of a natural disaster in their homeland.

The Three Dukes meet to discuss what to do about King Souma. In Amidonia, Gaius receives word from Georg accepting his aid, and prepares to invade Elfrieden over the objections of his finance minister. Souma delivers his ultimatum to the Three Dukes.

Gaius leads an invasion force from Amidonia into the kingdom and lays siege to the city of Altomura. Meanwhile, in Randel, the Forbidden Army constructs a fort from which they engage Georg's forces, while Red Dragon City receives its own surprise attack.

Souma and his entourage confront Vargas in his castle before hurrying off to Randel to regroup with the Forbidden Army. A stunning truth about Georg is revealed by Glaive, leading to a dramatic turn of events with Gaius and his forces at Altomura.

Under Gaius's command, the Amidonian army launches a full-scale attack to retake Van, but Souma and his forces move to stop them. In the aftermath of the war, there are serious consequences to be faced and plans for reconciliation to be put into action.

Jeanne Euphoria of the Gran Chaos Empire is sent to Van to deal with the occupation. Roroa observes the newfound freedom of the citizens of Van. Poncho locates a source of food for the impoverished citizens. Souma, Juna and Tomoe enjoy a day off together.

Julius, the son of Gaius, attempts to reclaim his former territory of Van from Souma, backed by the authority of the Gran Chaos Empire. The power to negotiate is given to Jeanne Euphoria, younger sister of Empress Maria Euphoria.

Jeanne's negotiations continue. These negotiations are no longer in the hands of Julius, but wholly a matter for the Gran Chaos Empire and the Kingdom of Elfrieden. Further, Jeanne sees a new future and a new world in Souma.

Van is returned to Julius as a result of the mediation of the Grand Chaos Empire, in exchange for a great deal of reparation costs. Souma returns to the Kingdom of Elfrieden, where many other problems yet remain.

Souma is victorious in both the Elfrieden civil war and the battle against Amidonia. However, his victory was won as a result of the devotion of a man named Georg. Still, the law is the law, and Souma must pass down a harsh judgment against Georg.

Weathering a number of problems, Souma more or less finishes dealing with the aftermath of the war. However, he was set upon by an inexplicable anxiety, the distress and pressure only felt by those in authority. It was not something he could bear alone.

Royal Guard Captain Ludwin's childhood friend, Genia, was a rare breed of mad scientist. Her inventions leave even Souma, who comes from a world of science and technology, in astonishment... In addition to being utterly dumbfounded.

With Van, the capital of Amidonia, returned to Julius, so too returns the oppressive rule of the government. The people's dissatisfaction increases day by day, until finally they end up revolting. Julius's sister, Roroa, then comes before Souma.

Roroa's arrival further complicates the situation between Amidonia and the Kingdom of Elfrieden. It was an outcome not even Souma had anticipated. In response, a conference between Grand Chaos Empire Empress Maria Euphoria and Souma must be convened.

An unusual Friedonian slave trader named Ginger Camus gave his slaves clean clothes and enough to eat, as well as providing them with an education, little knowing that this would eventually end up rocking the kingdom.

Refugees are one of modern society's great challenges, and the Kingdom of Friedonia is no exception. Refugees who had been driven from their lands by invading monsters have gathered outside the walls of the capital and started an encampment.

Souma and the others visit the refugees, where they help an expectant mother with a difficult delivery. The newborn life provides hope and a foundation for the future to the refugees, but not all of them accept the future Souma presents them.

One evening, Excel whispers to the fiancées Liscia, Aisha, Juna, and Roroa that she will teach them how to please their man, and suddenly commences a "Fiancées' Bridal Course". The secrets of Souma and his fiancées are about to come to light.

On New Year's Eve, Souma is summoned by his predecessor, King Albert, to talk with his wife, Elisha. The amazing truth told by Albert's mouth. And what's up in Souma's chest when he knows "everything"...
