Butcher Demon


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

There is an ugly beast that violates women in prison.

A treacherous beast that is feared and called a “Butcher”.

That’s me.

I was once a human but now I can’t even remember my own name.

I can’t speak, and I don’t understand a word they say.

It is in this deep loneliness that I am pouring my essence into the women everyday.

I pour my burning rage into them.

Over and over again, until they conceive.

From morning till night. Until the women’s souls withered.

To show them that I’m an excellent stallion and an obedient domestic animal.

But my soul has not perished yet.

I will break free from this prison soon. And when I do, it will be your last.

Every human who betrayed me, every demon who altered me, I will trample down like an ant.

And it won’t stop until I’m satisfied.

The dawn of the beast is near.

It's a fairly unique story, though it will definitely not be for everyone.

The protagonist is a former human turned into a (supposedly) mindless monster that only wants to kill and r*pe. (Stop here if you don't like that)

I like that you can tell he was intelligent, but is kind of dumb now due to the changes. He's able to make rational decisions, but not always able to carry through with them because he's a monster. It's a delicate balance and I think the author does an excellent job on... more>> that point.

Since the story is first person, the setting is not very clear (main character is insane) but is slowly revealed to the reader. I think that part is pretty good too. The humor relying on the protagonist's idiot strength is fun and doesn't get too repetitive.

But I'll add again that the h-scenes and various other parts of the story are not pleasant and there's a decent helping of tragedy. <<less

The author did something that I really hated. Do I'm giving it 1 star.

The MC has been betrayed by his own comrades and subsequently turned into a hideous monster. A real, disgusting monster. Not similar to an anime, where the protagonist's eyes turn red and his nails black, then says: "Don't look at my face!". The kind of monster with a face like a rotting zombie and a misshapen, weird looking body.

He is self-aware regarding his appearance and knows that any positive behaviour his r*pe-victims show toward him is simply... more>> for their own survival. Beauty and the beast fairy tailes are well and good, however in the real world something like that would never happen. A beautiful girl isn't even willing to date an average looking guy, never mind a deformed freak of nature.

He even kills one of his old comrades when he comes into contact with them, because he knows they will just use him as a monster when they are freed.

I thought this mentality of his showed a very realistic way of thinking of a person who got turned into a real monster.

Unfortunately, this doesn't last. Despite his conviction that no woman can ever really love him (which is the truth) he somehow becomes convinced that one of them is different.

This feels like such a sudden dumbing down of the protagonist and I can't even understand the reason for it.

He suddenly develops a blindspot for this one woman which is so out of character for him.

I feel like the author wanted to give him a weakness to add some tension to the story. It's s*upid and dumb. <<less

Let me first preface this by saying that I really enjoyed the actual plot a lot. And if the story isn't heading towards the darker side of thing I'd gladly give this novel a 5/5. The novel somehow managed to pull me in with both the plot and the "plot". Unfortunately, the author fully embraces the bleak and gloomy theme of the world and as such

ntr happened

If you are someone who can handle dark stuffs then this novel is a huge recommend.

I have a hard time writing these kinds of reviews, because I have such mixed feelings.

The premise is fine and most things seem kind of acceptable... but then the protagonist doesn't care when other guys have s*x with the women he's having s*x with. He even pushes them to who*e themselves out to others.

I just don't get the whole cuck thing. I doubt I ever will, it makes me cringe and its insane popularity boggles my mind.

As much as I had been enjoying the story thus far, I'm not really... more>> interested in reading a story where the protagonist is a cuck and/or whores out his women.

It's a shame that there aren't enough good harem s*x stories where the protagonist isn't a cuck and netorare-like things simply don't happen. <<less

As far as human to monster transformation is considerer this novel is at The very top. All those who rate it less than 3 points are salty kids. Common The tags say it all and if you still read it, it's pathetic to bash on those points. Anyway both MC and The side chars expierence character growth and we slowly get more info on them. The pace of The story can be quite slow. Some people complained that it's strange to get females to actually fall in love with MC,... more>> not considering The fantasy aliens who have different viewpoint. Human females can be incredibly Hardy and accepting when it considers survival. Stockholm syndrome, inherent or acquired masochism and genetic desire to chose strong and capable males. Add to The fact that 90% of The females would chose to acompany The butcher rather than to die outright, with repeated acts One gets used to it and it becomes The norm. <<less

(This first paragraph is a bit of a rant about other reviews. Just skip past for stuff about the story) This is a very vivid smut novel. If you are here you should realize that this is a potentially upsetting story about a large humanoid monster raping women. There is actually some rather vanilla aspects to this but there is plenty of more graphic stuff so don't come into this expecting vanilla. I feel like I have to specifically say that because there are plenty of negative reviews on... more>> here by people who apparently saw the title, saw the synopsis about pouring burning rage into women until their souls wither, saw all the rather dark and disturbing tags, and were then somehow surprised that it was full of graphic r*pe. I even saw one review that seemed surprised that this was a smut novel. This site does a great jobs of putting tags onto novels so that you can find what you are looking for and avoid what you dislike. Try using them. There is r*pe. There are also situations where some of the MC's victims/lovers are r*ped by others. This is not NTR. NTR is a more than just cheating or having a love interest r*ped. NTR is more of a full emotional betrayal. The Netorase tag is accurate though (and I know netorase is considered subset of NTR but it is pretty distinctly different here. MC is tolerant of some of his less-significant lovers sleeping with others because he is a hideous monster and because he is confident that he is far better at s*x than these attractive men so he doesn't feel challenged by them. And even then he is noticeably jealous about women he actually cares about.), because the MC does enjoy seeing his partners having s*x with others because he has this whole "I'm a hideous monster so I want them to enjoy being with attractive people" mindset going at first. But as of this point none of the MC's love interests (they are mostly r*pe victims but whatever) have been truly stolen unless you count

one being r*ped by someone else and later mu*dered and another being r*ped to death by someone else. The second one gets resurrected, the first one does not.

. Like I said, this has some messed up graphic stuff. If you don't like that, don't read it. Check the tags.

So with all that off my chest, what do I think of this graphic r*pe smut? I think it's pretty good. Lots of s*x scenes and the author goes into pretty graphic detail. Some of it is pretty weird since the MC is a monster with a 2-foot long prehensile tongue and an bottomless sex-drive. Also some pretty extreme bloodlust. The story establishes that the MC has been turned into a horrible monster that kills people in a pretty gory manner and will frequently eat its s*xual partners because of this weird mixture of lust and bloodlust that the MC is barely keeping contained through willpower. So at one point the MC is able to eat one of his guards, take a bite out of the skull to quickly kill him and then completely eat the rest of him, and still be considered a weirdly docile Butcher. That is the kind of gore we are talking about and while the author keeps it separate from characters we care about, there are some pretty graphic vore scenes. But that is more of a backdrop.
The author and the MC clearly both want to move into more of a story where the MC has a harem for purely s*x, and then the MC goes out to brutally mu*der people for the bloodlust. The story starts with the MC trying to escape and get revenge, and while the escape part eventually happens the revenge part gets complicated. It seems pretty simple: MC was human but was betrayed and is now a hideous monster imprisoned by the enemy. Kill them all. But we wind up with other characters trying to hold the MC back to preserve what is left of his soul. Also, the MC actually finds several willing harem members among his former enemy so at this point it is a legitimately interesting question as to how far the MC will pursue his vengeance and how much acceptance he will get from the two sides. There is a lot of maneuvering going on and the MC is a uniquely powerful weapon with valuable knowledge from each side. So we have the story where the MC wants to just f*ck, kill, and not think of complicated things beyond revenge. But at the same time there are harem members trying to find a comfortable niche for the MC on one side or the other of this war that the MC died fighting. Throw in some interesting worldbuilding and political agendas and some interesting plot stuff happens between chapters.

So give this a shot of you are looking for some dark smut with a monster male and human female. The s*x scenes are (mostly) nonviolent. The MC makes a point to be gentle with women (unless he was already planning to kill them) and this is one of those stories where r*pe victims become lovers so obviously he isn't particularly cruel to them. It is pretty extreme though, so if you are wondering if this is a good story to explore your comfort level, the answer is probably no. <<less

This LN break my expectation of conventional japanesse LN. Amid the satire fantasy genre trope that majority japanesse author used, this one mold it to dark story.

Some readers may not be able to entertain themself by the idea of the world setting that author used. But it was necessity for the author to lay the groundwork so the reader can understand better.

there is a lot of +18 scene in this novel and the author used it in various way. At early part the he used it to show us the... more>> situation surrounding the MC but latter he used it for mc's advantages.

The story part is really intresting, I kept wanting to skip +18 parts so I get know what will happen next

Author used of 1st person plus the nerf communication skill he put in MC butcher body makes the reader recive slow and little information that keep the msytery going which is nice but sometimes little frustating

overall solid novel, love it <<less

Writing after the first arc ended. Its an interesting one. I originally found it for the r-18 tag, but I generally just read it for the plot. Don't read if you are squeamish, but otherwise its an enjoyable one.

I just wanted to mention the r*pe tag. The protagonist is not a rapist. He is forced to have s*x for his own safety and survival in the hopes to escape.

His s*x drive/libido is not something he's supposed to have control over either. He was made that way. So whether his sane mind wants to have s*x with a person or not, his impulses will almost always overpower and choose s*x.

His lack of smarts plays into this as well. It's hard for him to focus on saying no to s*x... more>> if there is no explicit reason to other than the other party doesn't want it. Humans have the ability and mind to reject any s*xual impulses, but the main character does not.

I think it's valuable enough that he never dry f*cks and is focused on the other party's pleasure as well — especially after reading the scenes of the even dumber monsters with the same impulses.

So you're wondering who the rapist is? It's the alien government.

However, I have to mention he has occasional rapisty thoughts. The only thing I can say in defense is that he hasn't actually r*ped. But I doubt he will. As of now

there are a few people who have come to him without being forced by circumstance


ugh. Ch.64 he's using coercion on innocent little ferris! Even tho he's doing it to eventually escape, I feel like he has more responsibility this time. He helped create the circumstances he's currently in. <<less

So this is a soft core NTR Harem fic. The MC is an ugly monster, but that isn't what makes the story 'good'. Honestly, the whole take on his monstrous side and human side contradicting each other makes this a superb read.

Every dozen or so chapters, the MC acts morally, then sht hits the fan and he falls back to his beast instincts of mu*dering.

To summarize the first two volumes, the MC is a transformed human to monster. Who is forced to breed against 'his' will... kinda. The first volume... more>> is dedicated to his failing ego as a s*ave, while the second one is him finally freeing himself and establishing his dominance over the other half of himself.

Now that I'm in volume three, the focus is leaning towards his growth beyond a simple pet breeder and into a person who might become the antagonist.

Though this story isn't with out its flaws. The sole thing I did find truly off putting, is how messed up the aliens are. They're a bunch of hedonist enthusiasts.... Okay, make that 80% of everyone being hardcore s*xual deviants lol. With the MC eating what he NTRs... sometimes.

Yeah, some might find this a little overwhelming to read.

Rate 3.8/5 <<less

Sooooo yeah its just p*rn... but with a good story and intresting characters. Dam I got nothing more to say here. This not only has good s*x scenes, but also a good story and characters I would be intrested in even if it wasnt p*rn XD. Its good sh*t ngl. If you are in the market for a novel with a lot of s*x scenes you arent gonna do much better than this one.

When I found this novel, I skimmed the synopsis and said "it's not like I have anything better to do". This novel far exceeded my expectations. The characters are surprisingly well-developed and the copious s*x scenes somehow do not seem gratuitous in nature, and anything that would be the author has the sense to skim over. The black comedy hits very well and the pacing is enjoyable. This isn't a transcendent work, but it is a damn fun read if you don't mind the stuff in the tags.

What started out only as a p*rn butcher doing kinky stuff ends up with intertwined plot of war between 2 worlds. I enjoy this very much for the story

The segs scene is somewhat whatever tbh

Expect an inhumane MC. While MC protects and care for his really close girlfriends. He will eat innocents or even enemies when its needed

I can’t write an honest opinion because I hate everything about it. It’s non stop pain and torture. There’s 50 + chapters of self delusion and non stop r*pe mu*der and torture. If this is your kind of genre and writing style I’ll say this. YOU’RE f*ckING INSAINE.

that’s just my honest opinion. The MC can only have conversations within his own head for 40 chapters. 40 more chapters and it’s become complicated but he can. Then we go back to f*cking nothing.

the only part of this novel that is... more>> like easy to understand is that he has a craving for s*x that is unrivaled. And that it will happen. Often. I see reviews praising this novel for its writing but I don’t understand that.. At all. I can’t rate this novel for its “BRILLIANCE” apparently and that’s fine. So I’ll tell you. He r*pes. They r*pe. Stockholm syndrome. You’ll never know when the MC will snap and who will get dragged into it. You’ll feel like this whole thing is madness. I want nothing more to do with it. I held a faint hope that the setting would change. Maybe his race. The status quo. But no. If you’re waiting for hope it won’t come. Just leave. I am. I wasted a day on this <<less

2023.08.15 5/5 4vol. Chapter 295 (Chapters of regular or slightly longer length)

It's definitely a good piece, but one of the "either you like it or you don't" kind of thing. There is a lot of hentai in it and it is well written, but gradually the plot takes its place. There is definitely cruelty in it, but at the level of a film about a real war, not an action movie. (Many World War 2 documentaries that use footage of real events are able to show an equal level... more>> of cruelty, and often this cruelty is precisely in these newsreel footage.)

The protagonist is able to command respect. His character traits are intelligence from a science protagonist, attention to detail from a spy movie, purpose from a fantasy protagonist, and a high libido from hentai. He lives by certain principles and is definitely not s*upid. And the fact that he lives in this body only adds color to the picture.

The other characters don't look like cardboard backgrounds and have their own storyline, albeit mostly hidden behind the scenes. Of course, if you try, you can see the stereotype in them, but why do this while reading?

The background, events and structure of the world are well thought out, so far I have no doubts about the plot #Except for the school of aliens on the front line. I understand that this is a different culture and they are future soldiers and also relatively safe there, but I would not have a military academy so close to the front no matter the situation#. About 1 year has passed in the world since the beginning of the story, an anime could have been filmed based on the work if there weren’t so much s*x in it, there are no problems with violence for anime.

The 1st volume of history is the most colorful and vivid in terms of cruelty and s*x for the reader. But on the other hand, he immediately cuts off all those who would definitely not like this work, since it was not written for this group of readers. And this attitude of the author causes respect for the writer. Basically, the screening concerns moralists who are protected from the adversities of the world and live in their black and white or pink tiny worlds, or pe*verts who think only with their pen*s. For most of the remaining readers, there will be something in this work that can interest them. <<less

A decent smut, it seems like it's a gender bender though which I don't find interesting but the story holds up for a smut.

+Edit: obviously contains r*pe and disgusting stuff but I personally think it doesn't go over the top, for a smut, that is.

And the translation is fine, not good but fine.
