The second Okiraku Ryoushu no Tanoshii Ryouchi Bouei novel continues along the same path laid down by the first, with the protagonist cheerfully running around making weapons of mass destruction and plopping down new settlements one after another while onlookers watch in amazement. He does a bit of attacking toward the end here though, rather than defending, and it looks like the next book will be war-centric.
Speaking of wars, the fourth Tensei Kizoku, Kantei Skill de Nariagaru novel eventually wraps up its civil war arc. While it’s good that it concluded, the path taken ended up pretty unbelievable. Having a neighboring country (recently over its own civil war) throw away tens of thousands of soldiers in order to attack the protagonist out of nowhere is already out of line. Then giving them an infinite morale cheat on top of it? Incredibly heavy-handed.
Regardless, if the Afterword is to be believed the series will return to a more sedate recruitment-focused pacing in the next book.
