It is two years after the previous volume. Fuuga feels he needs to keep up the momentum and the only direction for him is to attack the Gran Chaos Empire. Souma is of course not to sit back and let his allies be overrun without a fight, nor do Maria and Jeanne intent to surrender.
The book starts with a bit of slice-of-life, explaining where everybody is standing. The majority consists of fast-paced politics, military movement and a bit of cloak-and-dagger. I like the fact that the plot is finally progressing, even if Souma still has a bit of an easy time. The theory is reasonably, I just wonder whether people would be this rational. At least this isekai is getting rid of slavery.
All in all, a good read.
