A Demon Lord’s Tale: Dungeons, Monster Girls, and Heartwarming Bliss


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.

This is Yuki’s story, my story. It tells the tale of how I spent my days after settling down in a dungeon with a self indulgent, “supreme” dragon girl and a young vampire.

Here we see that the voting should not be allowed to novels that don't have a defined minimum of chapters (unless they are short) or force comments to those who vote and avoid bad votes because of prejudice, I will not take into account the translation since I read it in its original language, so.

You must read it!!... you don't need to thank me.

5 stars - For not being boring (as an agent who wants to be a teacher in another world).
5 stars - For true comedy (not like... more>> that with a perverted highschooler with a red glove and his oppai here oppai there).
5 stars - For the interaction MC - heroines (and that's it, you should have enough with this, comparing with other novels that are better voted).
5 stars - Because I want a dragon Waifu (and caress her little horns and wings, don't forget the wings).
5 stars - For being more sweet than child-raising novels (that have no emotions in a world without cuisine).
5 stars - For never focusing on food (like mayonnaise and mayonnaise, wait, also add soy and...).
5 stars - For being a well executed cliché (although all the novels have clichés in some degree or another).
5 stars - Because the dragon Waifu deserves it. (no dragon Waifu no life)
5 stars - Because the harem is not a joke (it takes time, as well as the plants you have in your room because you are alone in this life...)
5 stars - Because I feel the love (that she never gave me...).
5 stars - Because this web doesn't accept anymore.

Bad jokes aside, the strength of this novel is the interaction between the main characters, I still think how I read more than 100 chapters without getting bored in one day, maybe the weak point (if it can be considered in that way, in a novel in which development is like a slice of life) is the variety of characters (as well as male characters) and the long development (which seems to be introducing more and more), even so, does not tire, like having a teenager with a smartphone with a pseudo loli harem, and the romance is not superficial and forced, as in that of a programmer who only wants the high elf or the pseudo political romance of the eighth child of a low-ranking noble. Even so, what many forget is about the dragon Waifu!!, how dare they, even if Kira forgives them, just remember those meromero (メロメロ) scenes, break my heart like a piñata... <<less

This one is thoroughly a slice of life novel, alright. What you should seek from this novel isn't fighting scenes, or schemes, or politics, or whatever heavy matters you could think of. It's a f*cking Slice of Life spiced with Comedy and mundane, down-to-earth, normal interaction between sentient beings who love to live their life leisurely.

Just enjoy this novel as it is. Why are you hoping something like Dungeon Defense from slice of life, geez.

  1. An interesting novel, not much has happened so far aside from a bit of action to show off how OP the MC is, which is what almost all isekai novels do.
  2. Feature a bit of romance which goes great together with the slice of life theme.
  3. A bit of a downside is that the translation quality is just bad.I feel like the translator "asian hobbyist" guy just feed the raw to some sort of machine translating program then throw in a few edit and call it done. It really sucks. The characters sound like robots with bland personality.
  4. Another downside is that, despite the already short length of the chapters, the translator goes out of his way to split them into multiple parts for non other than getting more clicks for ads revenue. He also holds up the already translated chapters for patrons, which I'm fine with, but he usually hold on to them for too long, sometimes for more than a month, which I'm not fine with. Even when u do as they say and paid 5$ for a chapter, he sometimes "forget" to unlock them so the chapters are only available for 20$~ patrons.
  5. There's a silver lightning that cardboard translation is picking this novel up, but just from chapter 33 onward so you still have to plow through 32 chaps of mediocre quality on a garbage tier site to get there. Good thing is "Supreme tentacle" is doing a great job with providing quality translation and seems very enthusiastic about it.

I don't know how the author does it, but they make the story simultaneously interesting and mind-numbingly boring. The main issue of it is the protagonist. He's basically a high school reincarnator with a chuuni supervillain mentality who denies he has a chuuni supervillain mentality, and as a result often does stupid things alongside brilliant things.

For example; he constantly insists he's not human in mentality any further, and can thus deal with certain things no self-respecting human would do, but then he gets cold feet with gore and the possibility... more>> of growing more non-human elements as he evolves. He's simultaneously lazy and hard-working, refusing to properly practice his skills but also properly taking care of his dungeon.

That being said, the slow-life aspect is fine. The lack of serious plot is fine. But the stupidity of the protagonist at times is really grating, especially since he does show competence in regards to other important tasks. <<less

TL;DR at the bottom

Okay, so far I love the story. The characters are interesting, even if the main character is a bit 2D it isn’t bad. The plots rather interesting, and the translation job is done really really well. You may be asking yourself now, why did I give this series 4 stars instead of 5 if I’m so in love with it? There’s a couple of reasons as to why I did what I did. While the translator is pretty good at their job, the person who is sorely... more>> lacking is the group itself. After one of the chapters in the early teens (ie 11-14), Asian Hobbyist started to split up each chapter into different pages. Now while that might not be a huge issue, the problem is that the chapter isn’t long enough to really warrant that. Some pages are as long as an iPhone 7 screen, so it make sense it a huge hassle to keep going all the way down to the page index, and clicking on the next one. Really takes you out of a series while you’re reading it. The next issue is the fact that the group uses ads, and while again in and of itself I’m totally happy about that since how else are they supposed to cover their website’s overhead cost, the problem is the amount. Each “page” has at least 8 ads on it, 4 on the top and 4 on the bottom which makes it really irritating to go from the top of the page to the page index button. The layout could be changed so that it’s a bit less intrusive, since each time I read a page of this series I suddenly get pulled out of it because of some clickbait article that could/could not be malicious in nature.


Okay, so overall the story is great, the characters are great, and I’m in love with this series. What I’m not in love with however is the translating group because of their desire to split each chapter up into multiple pages as well as use a ton of ads. Great series, great translators, awful website. That’s my only complaint about it. <<less

It's not that bad, but the wish fulfillment is absurd on too many levels.

I read through it, but the second he decides to become an adventurer as a freaking dungeon owner.. Nope, go away. This is not worth it at this point.

Well... it's bland... just ur usual reincarnation stuff, it basicly just like the title said.... don't expect much of it.... it's mostly slice of life stuff..... not that I hate it.... if there's something that put me off then that is :

... more>>MC didn't hesitate to commit a massacre, a bit of humanity still left in him, but all he did is issue a warning, once the warning is ignored he massacred them all without restrain... but the f**king thing is... once the invader is a girl he hesitate like.... wtf?!!! He just scare her off... now that realy putting me off/spoiler]

All in all the title said it all.... what the story is about, n the character of the MC.... I would give it 1... but the slice of life's not bad so I raise it to 2..... n the potential (i realy hope I hit the mark) of MC and lefy's romance raise it to 3.... for now 3/5 <<less

I must tell dat this novel had a good start, many aspects involved here dat make the novel it self such a unique one, comedy, hearwarming story, little bit of action so far, game elements like, and others.

For those who need some refreshing strory with game element and isekai background, I think this is the best one I found so far.

The chapters are short, without much content or descriptions, so for now it's another one of those "slice-of-life in another world".

Despite being in the dungeon master genre, it barely uses it and it is used here and there as an excuse to get materials and items for free.

Because there is a gatcha, you can expect plot luck of getting top-tier stuff way before he should be able to afford it (already happened once, maybe twice but we have no idea if the first one is potent or not as it... more>> has not been used yet).

You can read it if you want one more of those OP protagonists leaving a lazy life in a fantasy world, or give it a pass if you wanted something a bit more structured. <<less

Pretty standard slice of life isekai in terms of world building and characters, the writing itself is above average and the translation is good.

Recommended if you're looking for something of this genre, but it's nothing particularly amazing

It's a relaxing novel with comedy and some action. It's just heartwearming I guess?

It's a light hearted relaxing kind of story with a lot of goofing around and a little bit of action but not much.

If you are expecting anything serious this is not for you but there is a little bit of romance if you like that kind of thing.

Not many chapters released, so no idea how it'll end up. For now it's good, and I would had continuted reading if there were more chapters.

Overall I got a vibe of this novel being a rather slow-paced with lots of fluff and slice of life. If so then not my cup of tea.
