WARNING: HIGH SEXUAL 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

[collapse]

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.

Spoiler

I especially like the hero (lol). He never fails to make me laugh when the MC reads his perverted 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 pervert).

[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 virgin... And the C-section (can't forget that one, it's without anesthesia)

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.

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.

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 porn 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 porn, 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

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.

This is like slapstick comedy man x monster sex. 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

Seems interesting to see how the devil "repopulate" the world with different monsters. I would like to thank the new translator for picking this novel up, it is definitely going to be fun reading the "adventures" Mao-kun will go through.
