I was going to make several jokes about the lengthy wait for this final volume of Mixed Bathing in Another Dimension, but it turns out I made them all in my previous review, which also had a lengthy delay between volumes. Not nearly as long as this one, though. The last time this series came out was pre-COVID. Fortunately, this is the final volume, so we won’t have to worry about it anymore. As for the book itself, it has all the strengths and weaknesses of the rest of the series. I’ve always liked this more than it probably deserves, and that remains the case. But the book is, like its hero, just so goshdang earnest that it’s hard to dislike. There are really no surprises here, no last-minute twists. There are also (thankfully) no new women added to the bath pile, which is good, because as I noted in my previous book, I’ve long since forgotten who is who, with the exception of the tiny cast list at the start.

We pick up where we left off, which is annoying as I did not remember where we left off. But basically one of the summoned heroes, Nakahana, has turned evil and is using her gift, which is essentially “sleeplearning”, to brainwash people and have her own little army of handsome men. Fortunately, Haruno’s powers can dispel this gift, but it’s a one-by-one process, so it won’t be that easy. They’ve got to infiltrate a castle, steal the king, and then go to war with a brainwashed army. And try not to kill anyone, because most of the army is brainwashed, not evil. And then there’s the actual task that Touya has to do, which is to rebuild Hades and set up a massive temple with shrines to all six goddesses… which will allow most of them to once again reappear in this world. Fortunately, y’know, he has a bath.

On the minus side, Touya’s narration still tends to sound like he’s reading us his shopping list sometimes, and the book also can’t stop going on about “ripe melons” and “obscene tits” until your eyes get damaged from rolling them back. And everyone’s just so NICE. On the pus side, that’s because, in the end, this is a found family title rather than a harem romance. There’s no romantic resolution here, though you get the sense that eventually he’ll end up with several women. But it’s irrelevant, their bonds as family and friends are more important. Also, I appreciated how the book used its OP heroes. Touya and Haruno are both ludicrously overpowered… and so the book comes up with actual obstacles that stop them simply being OP, and forces them to strategize and think. And, as with previous books, the women all do a lot here, particularly Haruno, who gets badass interior art (unbrainwashing four knights with karate chops to the head) and comedy/sexy interior art (where she accidentally shows Touya her naked body while trying to meditate).

So yeah, still not recommending this to anyone but fans who don’t mind a breast fetish. But leaving that aside, this remains a flawed but pleasant series, with a very likeable cast, and I’m glad it finally got released.
