Suzuki Touru is a college dropout in need of a place to live. With only a part-time job, there are not many places to live…but he lucks out and finds a two bedroom apartment for 30,000 yen ($300). Yes, not sketchy at all! The moving his stuff in goes well, and then he opens a door and finds a pitch-black stone clad room also in his apartment. In other words, a dungeon — but the good news is he can still get back to his world! He just has to exit the window! Despite the dungeon in his apartment, dealing with that is no issue thanks to the cheap rent.
But of course everything’s going to change once he finds a beautiful blonde knight in the dungeon…
My Room is a Dungeon Rest Stop is the most typical manga adapted from a light novel there is. That said, the premise of being a dungeon rest stop was appealing. It could set itself up similar to Restaurant to Another World, where different adventurers arrive at Touru’s place, annoy him or eat his food, and never showed up again. Or at minimum, had the dude explore the dungeon a lot more than he does in volume 1.
Instead, he meets Ria inside the dungeon, who is paralyzed by a poison. He ends up saving her but not before he accidentally scares her into passing out (she thought he was goblin due to his look and his speech) and carries her back into his apartment after she wet herself. When they eventually are able to talk, he ends up lying about his circumstances about what he can do (she thinks he’s a mage due to all the exotic — some of it otaku — stuff in his room, and he decides to let her believe that) and then a very common set of elements occur — knight from another world is unfamiliar with modern stuff, hot girl takes multiple baths, and dude manages to get fantasy knight to dress in bloomers somehow, and she’s ok with it.
In other words, very typical stuff you’ve seen before.
That’s the most disappointing part of this manga — with the premise it has, it should be devoting more of its story to that rather than wasting an entire volume of Touru and Ria attempting to get used to each other. At least make it like two or three chapters. It loosely introduces some RPG elements as Touru tries to explore the dungeon, but it’s kinda lame. He ends up trying out different human foods and drinks inside the dungeon when he learns from Ria they seem to have given her stat increases; he fights a slime and ends up taking a really small slime into his apartment, and if that sounds boring to you, then yeah, I can confirm it pretty much is. The only good part is him trying to understand that Ria is in an unfamiliar world, so it makes sense for him to ease her worries, even if that means sleeping with her (and only just sleeping with her).
The start of the manga teases that Touru will head into the fantasy world with Ria, a slime, and a character that’s on the volume 2 cover. At least have some of that in this volume! Or unless it’s just a feint, and his trip into another world is not gonna happen. I would’ve taken that over this. It’s just a very ordinary manga with haremish aspects and a hot naked lady. Just go read High School Prodigies Have it Easy instead for a manga based on a light novel that’s at least fun.
