How a Realist Hero Rebuilt the Kingdom (Light Novel) Series

Summoned to another world to slay the mighty beast…of governance! The fantasy isekai series that inspired the anime!

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!

BROTHER, MY BROTHER

The Demon Lord’s Domain has been liberated, ushering in a new era. With the demons no longer a common enemy, the threat of a power shift hangs in the air. Who will triumph if the Maritime Alliance led by the Kingdom of Friedonia clashes with the Great Tiger Empire of Haan? While Souma is busy mobilizing his personnel for the impending conflict, Yuriga approaches him with a shocking request to return home. As it turns out, it’s merely part of Yuriga’s plan to corner her own brother, the Great Tiger Emperor!

TO THE NORTH

After 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!

EMBRACING CHAOS

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?

AN ACCURSED AFFLICTION

Following the political fracture, the three great powers are locked in fierce competition. When the haughty high elves of the Spirit Kingdom of Garlan come asking for help in reclaiming their land, King Souma refuses, and it is the Great Tiger Kingdom that deploys troops to aid them. But the Spirit Kingdom is plagued by a curse, a deadly disease that claims the soldiers’ lives and could threaten the entire world. Souma will have to merge his modern knowledge with the magic and medicine of this fantasy world in order to stop the spread!

FEEDING THE TIGER

Souma is hailed by Friedonia’s people after defeating the monster that menaced the Nine-Headed Dragon Archipelago. But outside his kingdom, Souma is overshadowed by Fuuga, King of Malmkhitan, who has reclaimed part of the Demon Lord’s Domain! In a stand against his growing power, the anti-Fuuga faction makes an attempt on Fuuga’s life, dragging the whole Union into a massive conflict! When the dust settles, will the world truly be the same?

BATTLE AT SEA

Risking her life to save her homeland, Shabon, a princess from the Nine-Headed Dragon Archipelago, joins Souma’s side in hopes of stopping an impending war. But with a fleet already en route to the hostile archipelago under his orders, Souma sets out on an infiltration mission before it arrives, and he discovers that the real threat is a massive creature in their waters that defies all common sense!

A DANGEROUS PRIZE

When Souma receives an invitation to a martial arts tournament, he has no plan to attend until he discovers two things: first, the grand prize is a single wish, and second, the daughter of his kingdom’s former general will be participating. Her father was arrested as a traitor, and she has every reason to hate Souma and the Elfrieden Kingdom. Now, he’ll have to discover her true intentions before she gains the power to start an all-out war.

A GIFTED STUDENT With Souma’s coronation and wedding behind him, he’s ready to send his little sister Tomoe off for her first day at the Royal Academy. But from her first step through the gates, she’s greeted with comments and stares from the other students. Tomoe’s adoption, her gift, and her older brother are drawing a lot of attention…good, bad, and possibly even dangerous.

FOUR WEDDINGS AND A CORONATION The ceremony that will turn Souma from provisional king to true monarch is rapidly approaching, and because Souma is to wed his fiancées on the same day, the capital is overflowing with excitement. Not overflowing enough for Souma, though, who uses his own marriage as an excuse to push his retainers to confess to their beloveds and tie the knot, too. Admirable as the king’s motives are, can the kingdom really handle all this romance, all at once?!

ALL’S FAIR IN LOVE AND WAR Souma pushes east toward the demon onslaught in the Duchy of Chima, where Duke Chima has been promising to reward those who distinguish themselves in battle by presenting them with one of his six remarkable children. Along the way, he meets Fuuga, king of the nomadic state of Malmkhitan. As they travel together, Souma learns Fuuga is also there to support the Duchy of Chima. The only problem is that Fuuga, who intends to be the decisive factor in turning the tides of battle, now sees Souma as a rival—competing with him for the reward of one of the Duke’s children!

MY RETAINERS ARE MY STRENGTH Beset by an unprecedented wave of monsters, the group of small to medium-sized countries known as the Union of Eastern Nations is in dire straights. Requested to send reinforcements to their aid, Souma dispatches troops to the Kingdom of Lastania—where Julius, former crown prince of the Principality of Amidonia, is currently holding the monsters at bay. And so it comes to be that Souma, standing shoulder-to-shoulder with an old foe, must depend on his retainers’ strength to save Lastania…

HAMMER AND TONGS Visiting the neighboring Republic of Turgis on a diplomatic mission, Souma’s eye is caught by the skill of the local blacksmiths—and an idea occurs to him. Sensing that he’ll need the cooperation of Turgis’s head of state to make this scheme a reality, Souma prepares for a dual display: show the republic both what they could gain from working with him—and what wrath they might incur if they refuse. Will this bold move work, or backfire on him?!

A STORM APPROACHES An invitation from the godbeast, Mother Dragon, takes Souma to the Star Dragon Mountain Range to attend the Contract Ceremony, where contracts between knights and dragons are formed. There, he meets and befriends flightless dragon Naden, who has always been taunted for her inability to fly. But Souma’s attempts to make her realize her own value are rudely interrupted when the Mother Dragon prophesies impending disaster—an unforeseen calamity is about to strike the Star Dragon Mountain Range, and Souma’s caught right in it!

THE ENLIGHTENMENT BEGINS! Souma visits Lagoon City, where he finds Castor waiting for him. But Souma is prepared for the encounter, and has an ace up his sleeve! Castor is left dumbstruck when the king unveils a top secret project he’s had the National Defense Force working on. Just what is Souma planning, and what role does he intend his disgraced former General to play in it?
