Two years have passed since the Spirit King’s Curse shook the world. In this time, Souma and the Kingdom of Friedonia have been preparing for an impending period of unprecedented chaos. However, the Kingdom was not the only country to burgeon over the two years. Fuuga has been expanding the border of his Great Tiger Kingdom of Haan as well. Following the acquisition of the Lunarian Orthodox Papal State, Fuuga sought to bring the Mercenary State Zem under his control. Now, having gained such powerful forces, he declares war on mankind’s greatest nation—the Gran Chaos Empire. With this move, an agonizing question now hangs in the air: should the Kingdom abandon the Empire, their ally, to avoid conflict with the great Fuuga Haan? The cruel war begins in volume sixteen of the revolutionary administrative fantasy series!

"Starting today, I will formally become the king of this Kingdom of Friedonia." Having returned from the Union of Eastern Nations and rested awhile, the ceremony that will turn Souma from a provisional king to the true king is rapidly approaching. Because Souma's marriage to his fiancées is to be held on the same day, the capital gets more lively than ever! Meanwhile, using his own marriage as an impetus, Souma encourages his retainers to get married, too.

But with a fleet already en route to the hostile archipelago under his orders, Souma sets out to infiltrate the islands before they arrive. As he gathers information within the enemy territory, he finds that the real threat isn't their naval fleet, but a massive creature in their waters that defies all common sense...?!

The Great Tiger Kingdom of Haan, the Gran Chaos Empire, and the Maritime Alliance headed by the Kingdom of Friedonia compete with one another in a newly tripolar world. Suddenly, the Spirit Kingdom of Garlan, home to the high elves, attempts to make contact with these three great powers. They desire to regain the land they lost in the expansion of the Demon Lord's Domain. Souma, however, refuses to help them, seeing no benefit in doing so. Meanwhile, the Great Tiger Kingdom accepts their request and sends troops. Things soon take a downturn as a crisis unfolds; healthy soldiers are collapsing one after another.

However, as far as the rest of the world is concerned, someone else has done something even greater—reclaim a piece of the Demon Lord's Domain. That is what Fuuga, King of Malmkhitan, has accomplished. Within the Union of Eastern Nations, Fuuga's power and influence rapidly expand.
