Sanada Shirou thought escaping his dead-end corporate job would mean peace at last—until he wakes up in a world where women rule the battlefield and men are treated like fragile treasures. Gifted with creation magic, Shirou figures the smart move is to open a cozy inn and live the slow life he's always wanted. But “slow” doesn't last long when the fiercest fighters and boldest beauties of this matriarchal world start checking in… and checking him out! Between building the perfect inn and surviving as the entertainment for his rowdy residents, Shirou's new life is shaping up to be anything but ordinary in this sexy isekai romp.

There's a bizarreness about the psycho-sexual landscape of Let's Run an Inn on a Dungeon Island! that I can almost respect. The protagonist, Shirou Sanada, is granted creation magic and sent off to another world while out fishing with a client of his abusive employer. The big twist is that this world is a matriarchy where only women can do magic, and men are seen as weak and frail.

Unlike most gender role reversal manga, this one truly commits to the bit. It imagines the standard misogynistic medieval fantasy world, where women are only allowed a small role and live under the constant threat of sexual assault, and switches it. There are no other male characters because Shirou is in situations that a frail, protected class would never end up in. In the first chapter, a woman tries to force him to perform cunnilingus, and he vomits from the odor of her stanky pussy (don't worry, he has plenty of enthusiastic oral sex with girls he likes later). When a random woman grabs his ass, another one castigates her and explains that, since becoming a mother, she can't help but imagine women treating her son that way. It's committed to reproducing misogyny and rape culture, but against men.

Don't get me wrong, it's not well-considered or subtle; Ōoku this ain't. It is, at its core, a fetish manga that has somehow found a way to reproduce the submissiveness and vulnerability that appeals to the audiences of oneeshota ecchi without the pedophilia, and I do appreciate it for that. It's also an isekai, complete with status levels and status screens, but it's not a total convenience-driven miracle skill. Shirou does have to put in work to gradually get better, which is important, as this is more of a disempowerment fantasy than anything else.

But, here's the big reveal: it's not a very good manga if you're not here primarily for jerk-off material. The pacing is positively languid, taking until nearly the end of the double-length volume to get to the titular inn or dungeon. It literally takes over 300 pages to get there. During that time, Shirou manages to enter into not one but two monogamous relationships, despite having little personality to speak of. The art is really only just okay, with far more attention paid to the tits than to anything else.

Every time I review a fetish series, I have to ask myself: how will it appeal to the people here for the specific kink? How will it appeal to those who aren't? If you're a malewife fan, you could honestly do much worse than Let's Run an Inn on a Dungeon Island! But if you don't want to touch your junk to enormous anime tits, this is an easy pass.

There is a very specific form of reverse sexism that assumes that if women were in charge, they would treat men the same way men treat women. It's not correct, and in places where women are in charge, like post-civil war Rwanda or Iceland, they tend to seek ways to improve lives for the entire community. But all that is irrelevant in Let's Run an Inn on a Dungeon Island!, where women are large, strong, sex-starved, and men are small, weak, stupid (let that concept sit there for a moment), and without magic.

It is into this delightful world that an exhausted worker for a toxic company, Shirou, finds himself transported. Predictably, he is not stupid or weak and has magic, thus enabling his escape from prison, where he was sexually assaulted by the prison guards.

Finding himself on a deserted island, Shirou builds his dream of running an inn. He's given a busty companion (all the women are busty, except the meant-to-be unattractive ones.) Sex magic helps him get more powerful, but what Shirou really wants is to cook! I can't say I enjoyed this manga for myself, but I can see that it has a place in the universe for folks who are not me. This does make me wish someone would write an isekai where an average dude is transported to a world where women rule, and everything just is pleasant and functional.

If a power fantasy about slow life innkeeping in a world of sexy women is your bag, you'll probably like this series plenty.
