The Hidden Dungeon Only I Can Enter Review (Spoiler Free)

Ok. Let’s keep on going with these fantasy anime reviews.

This one is the kind that has a title which basically tells you the premise of the anime. Which I once thought was sort of obnoxious or dumb, but I understand the reasoning behind such a title now (accessible mini-synopsis).

That said, I prefer a cool or well-thought out title.
So MINUS one point for the title!


Our protagonist is Noir Stalgia, a member of a lesser noble family who was just about to start his new life as a librarian when he finds out that someone from a higher-up noble family was abruptly given the position instead. Unsure what to do, he uses the rare skill that he was born with, “Great Sage”, which allows him to ask any question and receive an answer at the cost of debilitating headaches, and is told about the location of a hidden dungeon.

He arrives and in the dungeon ends up meeting a legendary adventurer from the past who has been sealed away, and she gives him her two most powerful abilities so that he can become a successful adventurer himself!

Slice of Life?

The genre tags on MAL list this one as an action / adventure fantasy anime, but I’m not so sure about that. There definitely is action, but I’d personally contest the adventure tag, as I wouldn’t say there’s much of a journey. Sure, Noir gets stronger and builds up himself / relationships with others throughout the anime, but he doesn’t really go anywhere or do anything special.

Which is why I’d say this is more like a slice of life anime. A little more happens than the average slice of life, but the overall feel I get is that of a slice of life. It’s kind of just Noir doing whatever comes to him, reacting to the environment around him.

In addition, he ends up with a bit of a harem, which is another subgenre I’d more commonly associate with slice of life than adventure.


Not everyone is a fan of ecchi, and well, there’s a decent amount of it in this one. One of the premises behind one of Noir’s newly acquired skills is that he benefits from lewd acts with others. And so this gives the anime an excuse to show us plenty of ecchi material.

Personally, as a fan of the genre, I thought the ecchi content was pretty good. The anime isn’t very serious, so the ecchi just fits in well. Of course, the justification for it doesn’t make much sense at times, and like many other harem anime you begin to wonder why the protagonist doesn’t take things further, given he actually receives a tangible benefit from doing so.

But these things aren’t really supposed to make sense anyways, in these kind of anime.

Noir’s Ineptitude

I won’t spoil how anything works, but let’s just say that Noir acquires a specific set of skills, skills that he uses throughout the season to get stronger and overcome obstacles. And the anime frames it as if he’s sometimes in a tight position, and he has to “get creative” in order to get through things.

Problem is, he doesn’t use these skills well at ALL. As I said, I won’t spoil anything, but man, Noir seems to have no idea how to really go nuts with his skills. Basically, the sky is the limit, and instead of really becoming overpowered, he just scrapes by.

It’s not that big of an issue or anything, but while watching, I felt like there were pseudo plot holes the entire time due to how tame Noir was. Noir is basically your typical harem protagonist, through and through, happy-go-lucky and just sort of goes with the flow. So I guess it’s not surprising that he’s not all that creative when it comes to abusing his abilities.

If you’ve seen enough of these types, you’ll know what he’s like.


I’m giving The Hidden Dungeon Only I Can Enter a 6.5 / 10.

It’s a decent anime to watch just for the hell of it. Never is there really a moment where I was at the edge of my seat, or really excited to watch the next episode. But it was just sort of enjoyable overall. There’s some good ecchi eye-candy, and I’m always up for checking out another fantasy world in anime.

Not the greatest, but not terrible. Unlike some others, this is one where I don’t really care if there’s a sequel or not. I’d watch it, but I’d just as soon watch something else.

That does it for this review.

Next up is likely another fantasy anime, as I have a bit of a backlog in reviews to write. I watched these anime several months ago, but just didn’t get around to writing the reviews for them. So I’ll get through those first, and then I’m not sure what I’ll do.

Maybe finally continue with the Monogatari Series.

Until next time,
Thanks for reading.

  1. “you begin to wonder why the protagonist doesn’t take things further”

    That is a damn near universal trope in harem anime. I think there’s a law requiring it. I’m thinking the point is to make the male audience fantasize about all the things they’d do if they were in the protagonist’s place. By extension they get to feel superior to him. The MC is even more of a dweeb than they are. At the same time, those who feel differently can praise the MC for his restraint. And some of the shyer audience members feel reassured that it is OK to vapor lock in the presence of willing and desirable females.

      I’d actually never thought about it that way, but that’s a great point. The dweeb character usually just irritates me, but when you put it like that, I can see why some people might enjoy it.
