Contains the full Volume 3 and 4! The Subjugation War Begins! With supplies in place, plans made, and alliances forged, Souma's mission to subdue the rebelling nobility has begun. With a pocket full of tricks, loyal subjects, and modern knowledge, this should be easy! Well... not if you want your civilians to escape unharmed. Or if adventurers keep treading across the battlefield. Or if your nosy neighbors think this might be the best time to launch an invasion of their own. As the conflict expands, it's up to the crew to find a way to win without falling prey to tricks, manipulations, and schemes behind the scenes. Can Souma survive? And with his reputation intact?

The Battle Continues! Souma presses Elfrieden's siege on the Amidonian principality, whose soldiers fight tooth and nail to keep him at bay. The violence on the front lines is bad enough, but a surprise attack at the rear will confound the bloody battle further. Souma and Carla must fend off Gaius themselves in a life-or-death test of nerves, loyalty, and steel. When hard-fought victory finally dawns over the capital, it's time for the realist hero to get to work. Souma now needs to win over the citizens of the former enemy nation, and he has a most unusual plan that just might do the trick.

And even when he does manage to catch a break, a day off with his staff provides anything but: rebelling retainers, natural disasters, and the threat of war all await. Can Souma keep up without succumbing to the stress?
