WARNING: HIGH s*xual CONTENT

The story is very unique, with a lot of thought and research put into the anatomy of each monster. It's amazing how the author considered the unique characteristics of each monster to form their unique personalities and backstories. I really respect that after so many monsters, each one feels refreshing and unique. I was also surprised that this wasn't just a fantasy about having s*x with monsters; not all monsters are friendly.

I also like that it has a bit of philosophy and touches on subjects such as... more>> pollution and, well, the end goal of world peace for both sides.
Spoiler

For example, I loved the portrayal of the hero. He isn't a bad guy just because he's the natural enemy of the demon lord and kills monsters. The hero has his own troubles. The demon lord tries to understand him so that both sides can attain peace, and the hero, who fell in love at first sight, falls even hard for him.

[collapse]
It shows that while this is 95% smut, the 5% of world building helped make the world immersive.

The author occasionally writes a chapter where you see all the major monsters collected so far, so if you like one, chances are, it'll pop up again. <<less

Many disgusting moment but the story is absolutely soo unique and interisting. I like the mind break and psychological event. Ahhh and the story of each monster. Especially the story of the hero in this story

[who is fall in love with him. Many misunderstanding the maou had to hero, but I like it when he planning to negotiate with the hero, and try to understand his place as hero. Kuhhh I wanna them not be an enemy, really. Even though the hero is an absolute pe*vert, I like his story....]

Anyway this is a wonderfull story and if you can telorate some disgusting event here and there, then you will find a beautifull story... <<less

It's pretty good despite being too graphic. Most of the characters (mostly the humanoid ones), even with almost no character development, are likable.

... more>>
Spoiler

I especially like the hero (lol). He never fails to make me laugh when the MC reads his pe*verted thoughts. He's super OP being lvl 800+. Despite being the hero, thus, an enemy, he's quite hard to hate especially once his background was told. Beside him, I also like the dark dragon (according to google translate but it could be black dragon), fenrir, basilisk and vampire (that cosplay pe*vert).

[collapse]

Just a warning though:
IT'S HARDCORE YAOI SO IF YOU'RE NOT INTO THAT THEN I DON'T SUGGEST READING IT. And also, that r*pe and Pregnancy tag is not for display (bestiality should also probably be added just to be safe even with the monster tag). Almost all chapters contains s*x scene (not that it's that much of a problem since that's most probably the reason why you're reading this) and considering that the MC have the body of a child with adults (if it was even in human form) as partner, you can pretty much guess how it ends. If you're fine with that then you're good to go.

Spoiler

Seriously though...A giant, Kraken, Leviathan, etc. Then there are some with multiple partners... His body returns to it's previous state which means he's always like a virg*n... And the C-section (can't forget that one, it's without anesthesia)

So far the story is very entertaining, due to its incredible wackiness. It's definitely not the usual plotline you see on NU, and both the writing and translation are pretty good.

... more>>
Spoiler

The MC is 100% confused, but he also has a spine, despite mostly going with the flow (forced to). The "system" that guides the MC is hilarious because of how merciless and blithe it is to the mc's confusion, though it does help the MC somewhat. The story development is too fast paced so far, but it's forgivable with how entertaining it is.

Warning for weird stuff such as shota, mpreg, laying eggs. It's also implied there will be bestiality in future chapters. It's not exactly a new kind of p*rn on the internet but definitely isnt the norm for NU.

Edit for ch24: r*pe. Tbh I should've known it was coming. Previous chapters had dubcon situations, but this was the first one where it was explicitly noncon, but then the rapist had a sad backstory and MC Forgave and Accepted him and yeah, f*ck that. I'm tossing this one out.

The story started out as a pretty fun, unapologetic p*rn, but it's gone into far more dubious stuff. I'm pretty sure the author's just trying to fit every possible kink into the story, but that's made the story lose its fun for me.

By now I'd say half the s*x is dubcon, and it's just unpleasant to sit through now. I draw the line at excusing r*pe. Changed my rating from 4 to 1 too.

[collapse]

Edit: see spoiler. Changed my rating since reviewing at ch4 <<less

I love yaoi period.

So when I read the synopsis, I was instantly hooked. It's not like previous yaoi I've read when it takes a pretty good amount of chapters before you get to the steamy part. No, it skips all that and takes a plunge into parts that make you want to blush on the second chapter.

But, you know that you are expecting it as soon as you read the summary so it's not that surprising. Every single chapter is basically filled with s*x.

I'm really looking forward to the releases.

The novel is simple, straight to the point, and very easy to read. The tone is light hearted and humorous.

The characters lack a bit of depth and dynamism, but its just the start. So, we will have to wait and see. Even so, they are quite likable.

The story doesn't dilly dally with unecessary filler chapters to the point of it being fast-paced and linear.

Points for you to like this novel (If you do not have any of these or can bear the ones you are missing, it is better not to read this) :

1.- You like the shotacon (Just to remind you of the fact that he is reincarnated, so psychologically he is an adult, that does not take away the fact that his body of less than one meter has to support horse-sized c*cks (literally))

2.- r*pe (There is not much to explain here, it is something really explicit, read at... more>> your own risk)

3.- s*x (In all the chapters, at all times, with all kinds of monsters, which do not necessarily have a humanoid form, with two at a time and a large etc)

4.- Zoophilia (? (They are animals that have conscience, but they do not stop being animals, poor Maou-sama)

5.- Mpreg (If you have no problem reading how Maou-sama lays MANY eggs with his little body, so good)

6.- Disruptive adults (Yes hero, I'm looking at you, I'm afraid to read your dark thoughts about Maou-sama again)

7.- Possible in*est (Well, this has not happened yet, but because of how your children are behaving and because of how obscene and morally this novel is, it is very likely that it will happen at some point)

Here are the 7 deadly sins to which you must show indifference (or twf taste) to read this, after all it is just fiction. I do not know if saying that I liked it is disturbing, I would not reread it, but the curiosity of seeing how all this ends is what makes me keep reading.

I give it a 4 because the plot (don't expect much either, the development of romance is slow because s*x occupies the plot more) and the writing is nothing to write home about, I must admit that the variety of f*cking monsters is surprising, there are few scenes that seem repetitive, reading this novel is like eating popcorn while watching a good movie, when you realize it is over.

Besides that I admire the translator for the effort she puts into this. (THANK YOU VERY MUCH, TRANSLATOR <3) <<less

I won't deny I crave and like smut tehee. In reading only I meant. I've noticed that some people do not like High s*xual Content and this one might be a little no maybe above average and it's hardcore so hope you keep this in mind when you open a chapter. But for me this is a 😫 5 star coz' it matches my taste.

So for a smut one, it's OK....... for some reason the author is obsessed with sigmoid Colon which is kinda a turn-off cuz she/he/they keep repeating the same thing again and again. Otherwise, I kinda like the wholesome vibe I get from this book 😌 (leaving the fact that there is graphic gore and r*pe............ yea leaving that aside. I get uncomfortable talking about that). I love Veleke and Chaos (the dragon) and Copper (the dog?). They are my bias. What I find interesting in the novel is that the... more>> Maou (The MC).... doesn't have a name. Like he's called Maou-Sama but he doesn't have a proper name. We don't know his name, actual age, past life as a human, occupation in his last life, family anything. He's the most mysterious character in the book and no one questions it either. Like Noone asks him what is his name....... they all just Call him Maou-Sama and he's fine with it as well. One word to the author is that I would love to know what his actual name, age, and personal info is. That's all otherwise it's a pretty nice novel. I always look forward to seeing it update.

EDIT: So I read up to chapter 102 and I'm frankly surprised. Towards the end, the story got rather serious with the whole
Spoiler

Maou and Hero having s*x so Maou can give birth to a baby who will bring peace to the world and end the whole war thing with the demons. He gave birth to twins btw.

[collapse]

The ending was seriously sad. I didn't cry but I really felt sad.
Spoiler

There are two parts to chapter 100. The first part and the second part are the same but in chapter 100 part 2 we get to see that the Maou's body is left but the soul is gone and a new Maou is born.

[collapse]

Honestly? For a purely mind-numbing smut novel, the plot was actually good! With good humour, Weird s*x (That I kinda feel uncomfortable about but whatever), some seriousness and literal wholesomeness this story is actually good! *insert surprised Pikachu face*. I have to say that this was well thought out and I really am happy that I gave it a try. I had been contemplating whether to read it or not and I'm happy to say that I don't regret it at all.

P.S: We get to know more about Maou's past life as a human and we get a little surprise element in the end. <<less

I loved to read this for some mindless smut but I guess 56 is a good time to stop.

Spoiler

I'm so tired of reading the author writing about the monster fcxking MC's sigmoid colon. It's not about the chrysanthemum anymore, everything has to be at the sigmoid colon or it's not sxx (it seems to the author).

It hurts to read how MC repeatedly screaming it's hurts while getting his hip bones dislocated or disemboweled.

It's not an enjoyable sxx if only one party is enjoying it.

I click this for yaoi and smut but stayed for the plot.

Spoiler

Not gonna lie. This is actually legit good but what erks me is that he is in a body of a child. Basically hes a shotacon. Because he was born too early.

He's a forever a virg*n state everytime he recovered (so ouch!) + Big monster dicks in that smol body (oh noes)

Im glad there are monsters that really take it slow on him, give him the love and care. They genuinely love him. BUT there were still those that r*ped the poor kid and I am flipping a table when I see him hurt.

[collapse]

The story gives insight to the grief for other monsters that were left alone as the only surviving species of their kind and its truly heart breaking. This story aside from s*x and smut. Also has a psychological feel to it and you cant just point fingers to blame anyone because they all had their reasons to why this and that.

Its a really great story that balances the fluff, angst, humour and smut

Ahh I feel like I understand why the monsters love the demon king (maou) because I cant help loving him too. He's such a precious treasure <<less

This reads like a biology textbook that covers the mating habits of monsters with children. Yes, children. The MC's body is a 10 year old child who's only job is to let literally anything f*ck him in order to breed.

You'd think this would make the story really dark but no, remember it's basically a textbook. Even the torture, r*pe, and forced breeding of a child comes across as dry and boring. You never really get to know any characters, there's barely any world building, there's no romance, no smut, it's... more>> just a dry reciting of how monsters breed with kids.

I'm giving it one star because it's boring. <<less

By all means, if people judge you as pe*vert for reading this, it's pretty much justified.

There's a lot of questionable content here, with the MC pretty much always screaming in pain every interc**rse. It's a combination of r*pe, pedophilia, gore, and monster fetish. I think I haven't dropped this one yet simply because it's in novel form and not graphic, so I could just blanked out all parts that I didn't like.

Velke and dark dragon best boy, the hero is a tr*sh.

So the MC has transmigrated as demon king and his job is to increase the population by ***. He would have a harem with people loving him and his children are so cute. My favourite is Velke. Though one chapter is gore. What I like the most is MC is been shown as traumatic from his experience. Like it's how thing are in real life, you can't forgive someone so easily.

The MC is a child dude like he has a body of 10 year old.I wonder when he will grow up.

This is like slapstick comedy man x monster s*x. This series makes me feel a baffling combination of being feeling turned on and laughing so hard that tears come from my eyes. I'm not entirely sure how to react to this series, but I really like it and caught up with all the recent chapters in one sitting!

The comedy is great. The monsters are great. Even the world-building and setting are great.

And then... there's the hero lurking around in the background, upping the suspense and tension with every appearance.

This series... more>> is definitely bizarre, and I am not sure I could read it if it were in a graphic novel format, but it's definitely worth checking out for those who are curious or just like yaoi!... If you are neither curious nor interested in yaoi, however, you may see something you might not be ready for. In that case, your world may be opened to a whole new range of experiences you're not sure you ever wanted. You have been warned. <<less

Rating : 3.5⭐️

The story is fun and interesting, and I kind of like it more than I originally thought I would. Thanks to the author's hiatus and the sudden change in his/her writing style, the story gets a lot better and more fun to read even though the author's note stated that the plot and the ending is fixed (originally, I rate this 2-3* for the chapters before the hiatus).

First of all, *big warning* since the MC is extremely young and has an elementary school student physique, this story is... more>> strongly pedophilic. It also contains a lot of gore contents, hardcore and rough s*x which may disturb some people.

Personally, despite being uncomfortable with MC's external appearance at first, I must admit this story is strangely addictive (even though I practically skimmed through most of the gore and painful parts). The whole story is basically about MC breeding and laying eggs in loops, and although I don't think the plot is extraordinarily impressive, the smuts are kinda exceed my expectation. Like seriously, I really appreciate the author's uniqueness and creativity in writing smuts. It truly opens my eyes and expands my horizons. 😂 The only thing I regret in this is that there's barely any bonding or relationship development between the MC and his husbands at all, except for a few important characters. It would've been great if the author can add some more development to their relationships after the interc**rses.

Nevertheless, I love the ending and chapters towards the end very much. It was written very beautifully and the casual smut story appeared to be meaningful and very touching. 🤧 Gosh. I am so in love with how the story was wrapped up. I didn't expect it to be this good at all from my first impression. The children of the demons are also extremely adorable. If only I could unsee those messy early chapters, I'd definitely rate this novel higher. Thanks to the translator for sticking to it until the end!

Spoiler

To be honest, it's disturbing af when I saw the author's note, saying he/she wrote this story as a material for his/her own use (m*sturbation). I mean, seriously? Is the author a potential predator? A pe*ophile? That talk is very suspicious. I hope it's just my misunderstanding or the fantasy, and he/she isn't an offender in real life.

This book is completely PWP, or at least very little plot. That being said, there are plenty of cute fluffy moments as well as some darker moments. I really enjoy this book, it's brilliantly translated, and I love seeing the interactions between the demons, the kids, and the main character as well as the different types of demon and their personality. Once again, it's mostly s*x scenes as well as mpreg, not too much plot.
