ONWARD, TO THE NORTH!Having taken back the Kingdom of Merinard, Kosuke and his allies get busy with restoration efforts. But while they're hard at work, news comes in from the north that the Principality of Diieharte and the Kingdom of Tigris are preparing for war. A special task force is formed around Kosuke and Ira, with Shemel, Bela, and Tozume as backup, and together they head off to defend the borders of their reclaimed kingdom!
While it isn't unexpected, I feel way too much time is spend on the MCs relationships with his way too accepting harem and not in an interesting way at that. It is all surface level lust with little romance or character growth. It comes with some decent R&D and a reminder to the MC he can do better and especially faster if it comes to settling his main goals. So there is some progress later on and that section makes it a decent read in the end, but I really hope the plot speeds up.
This time Kousuke has to repel an invasion from some Holy Kingdom vassal states. He also spends quite a bit of time being conflicted by his role in the slaughter of so many during the course of wars so far. At least, he does when he isn’t constantly having sex with his expanding harem of monster girls. It was good overall.
