There’s a bit right at the end of this book where all the nobles ask Haruka why he’s not all that worried about the Empire invading, even though they clearly are saying they’re going to do so. And Haruka utters a stream of gobbledegook, as he always does. But when translated by Book Club President, it amounts to: they don’t want to invade, they want all their enemies to collapse from within and then waltz in as saviors. It makes a lot of sense, though Haruka is also well aware that there’s a time limit on this, and I suspect in the next book we may finally leave Omui to go somewhere else again. Because this is the third book in a row where the plot is basically Dungeon, Inn, Dungeon, Inn, over and over for nearly 500 pages. The dungeon stuff is mostly filled with Haruka’s monologues about how he’s trying to improve, why no one will let him do so, and the occasional sensible observation. As for the inn, well…

On the cover is Haruka’s new servitude victim, an archdemon that Haruka decides to name Morning Star Archdemon, after the weapon he gives her. That said, relax – not only does she look like an underage gothic lolita on the cover, but Haruka thinks she is as well. So she’s going in with the demon scythes and the chickenatrice, in that she’ll be seen fighting but will not be part of the ongoing bedroom adventures. Which is good, as those are taking up more and more of the book. The book is still somehow rated OT rather than Mature, probably as Seven Seas knows that this series is not exactly picking up any new readers. That said, I used to say that the sex was there but ignorable because Haruka’s narration mostly made it incoherent. That is mostly true, but we also now get narration from the girls, which is a lot less incoherent. Honestly, I’m impressed the author has almost made this all plot relevant – the Dungeon Masters clearly want the other girls to get with Haruka as well, but know that, as they are and as he is, he would simply break them. So there’s training instead. Which involves either a lot of “stamina training” and also consumption of some “miracle medicine”. Class Rep seems to be doing better than the others, mostly as she’s their sacrifice half the time. Anyway.

In non-sexy and dungeon-related stuff… there is a bit of it… we see Haruka trying to open a portal back to Japan so that he can send the girls back home. (He’s given up on the guys, who are either married now or avoiding getting married.) He’s thinking of their families back home, and also worries that if he lets it go too long they’ll be too inhuman to ever really return. I have news for Haruka, that’s long since already happened, even if it’s only been four months since the start of the series. The girls all know this too – they’ve explicitly told him they’ve come to terms with the isekai and are staying, but he is, of course, ignoring them, mostly as he still feels responsible for everything. The Dungeon Emperors don’t only do “sex training” with the girls, they also do dungeon training, and they’re the biggest hardasses out there. Mostly as they know the girls have the same issue they do – if Haruka gets strong enough that they can’t be at his side anymore, their hearts will completely shatter. Meanwhile, Haruka thinks the ideal solution is to not have anyone he cares about at his side. You can see why this isn’t getting anywhere.

So yeah, we read another 500 pages of wheel-spinning, as the author admits in the afterword. Will things happen in Book 16? We can but pray.
