With the talks to relinquish Van concluded, Souma returns to the Kingdom to meet face-to-face with the primary culprit of the rebellion, Georg Carmine. When Souma presses Georg about reasons for committing such a crime, the man remains silent. Refusing to talk, and no recourse left, the once famed general is offered “poisoned wine” as a means of atonement... Following this, Castor Vargas, the remaining culprit in the rebellion, is put to trial. “What do you think is the appropriate judgment for fools who raised the flag of rebellion against me?” Souma’s treacherous allies promptly call for the death penalty. However, in order to protect what he must, Souma makes a decision that calls into question his determination as king.

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...

During a conference with Empress Maria of the Gran Chaos Empire, Souma is asked to dispatch reinforcements to the union. The place Souma sends those troops to is the Kingdom of Lastania.

The Gran Chaos Empire is the largest nation on the continent and the leader of the Mankind Declaration, a united front against the demons. Amidonia uses part of the text of that declaration which states, "The moving of national borders by force will be deemed inadmissible," as their shield, borrowing the might of the Empire to demand the return of their capital, Van, but Souma refuses. And so, negotiations begin with the Empire's envoy, Jeanne, the younger sister of the Empress. "We do want to enter an alliance with the Empire. A secret one." With the tempest of war behind them, the goals of the different nations send sparks flying in the seventh volume of this transferred-to-another-world administrative fantasy series!
