The story is fun and interesting so far. This novel is your typical 30 year old salary man reincarnating in another world. The MC reincarnated as a son of a powerful noble family and he use his power to force women to have s*x with him. So far, the MC's character is not really that good towards the women since he use threats and deception to force them to have s*x. The good point about the MC is that he feels real than MC from many other adult japanese novels... more>> I have read. He was originally a virg*n so he's not used to many experiences when it comes to s*x and would often react in a fresh way. The s*x scenes are so far just fine. The interactions while they are doing it are fun and stimulating. Another plus is that female characters are not instantly turned into s*x beasts and fall completely in love with the MC after they have s*x.

If there's a problem with this novel, it lacks real plot, or its not focused in it. I feel more like I'm reading a slice of life story about MC's daily interactions, s*x life, and how he uses his authority force the girls. The good point is that the novel is more realistic when it comes to reactions and everything else. Unlike many novels I have read such as Road to Kingdom, where the MC has an extra large horse c**k and the female characters would instantly jump at it the moment they see it like they are hungry wolves.

Read this novel if:

    • You have r*pe fetish.
    • You want many +18 scenes.
    • You want realistic reactions / characters.
    • You want a fun and casual read.
    • You like a slice of life-like +18 novel
    • You want an assho** MC.
Dont read this if:

    • You're a faint hearted person.
    • You want a story focused on plot rather than plot.
Anyway, I would still recommend it if your a real man of culture. <<less

You know what I love most about Novelupdate reviews? It's when people review novels using their own personal preferences despite the novel obviously not fitting that.

It's so common now that I can't get mad over it. Reader comes into a medieval themed novel about a marquise abusing his position to r*pe people, has the tags "R*pe", top reviewer warns about r*pe, but the reader reads it and then leaves a negative review because the protagonist r*ped someone. Forcing someone to have s*x without consent nor consideration is r*pe. If you... more>> want to complain that the girl, which the protagonist is forcing to have s*x, doesn't want to have s*x, you shouldn't be reading this in the first place.

Moving past all of that, this novel is very different from a lot of other adult novels on this site. It favors being realistic over the many tropes found in JP literature. By that, I mean the protagonist feels like a real person, the characters and relationships he starts feels realistic, and the reactions as well as the world feels genuine. I'm sure plenty of other reviewers cover this stuff better than I could, but I still want to reiterate that you are almost certainly not going to enjoy this novel if you are looking for common 18+ plots.

This means characters won't fall in love when being r*ped, our incredibly young and virg*n protagonist is going to be pretty mediocre at s*x for a while, and the emotions as well as actions of our protagonist will be more human. I recommend giving it a try as it's definitely unique, but understand that some people obviously won't like it. <<less

One of the top novels for this year in Japanese raws. While there are some r*pe, MC can be considered morally neutral from the perspective of his current world. He mostly use coercion to get what he want (sex) rather than just plain r*pe, after all he has really high status, so why wouldn't he? The willingness of women ranges form forced r*pe to pure love, so we have a wide spectrum. MC is also caring (as caring as someone can be if he forced others in the first place)... more>> and tries to improve his women's lives to some extent.

Now the reason I enjoy this novel so much is the realism aspect. First of all, MC acts as 9 out of 10 men would in his place, that is if you have power, status, and your actions are considered normal by society you live in. Frankly, morals are relative and change depending on culture and other factors, so it really annoys me when MC in some novel tries to imose his moral values on whatever world he is in. The second is character development. You can see slow shif in attitudes of his women and reasons for that. Some are faster and some are slower that MC might have wanted, definetly more realistic than 95% of harem novels. <<less

I liked this novel, it's just as the title says. The MC is true to his feelings and he isn't a wuss like many Japanese MCs or an hypocritical idealist. Also anything related to the MC is not absurd such as cheats, powers or some magnetic field for beauties or harem; in fact he has none, which makes the story more interesting and fun. The story is not slow paced, the details are omitted for anything that's not related to the s*x life of the MC (it's not bad, it helps you skip through useless descriptions or minor events if you're here just for enjoying the core story described by the title). Nonetheless the story is clear even without those details, you won't even feel them needed. The interactions and dialogs are in place, the characters dispositions are well done and their development is promising. Don't read it or give it 1 star if you're against fictional r*pe


there may be even in*est as the MC reacts to his sister's charm in a "not brotherly way"


The translation is very good too I hope there will be more release and never drop this fabulous gem.

This novel is actually quite a snooze. The author has constructed it as a loose collection of bland "domination" scenarios that span 2-3 chapters long, interconnected with some very boring world building. The scenarios themselves are really uninspired and the lack of evocative imagery for both the female characters and the s*x descriptions is down right criminal in this type of work.

The biggest mistake that the author makes is probably being too shallow and cycling through new women to be conquered too quickly rather than properly spending the time to... more>> build up a good erot*c scenario. For instance, right at the start of the story the main character acquires an Elven s*x s*ave who obviously needs some training and breaking, he also finds out that her mother is a s*ave for sale as well and plans to buy her. However, instead of showing us several dozen chapters of the process of this guy breaking down and turning this mother/daughter pair into his personal sluts, it's never revisited for dozens of chapters and instead we he bangs some maid (that we don't care about) some tavern girl (that we don't care about) and a merchants daughter (that we don't care about)... I think you get the picture. None of these characters really matter and the scenes with them are boring as hell - you literally could not sport wood if you downed an entire bottle of viagra.

On top of all the above, what makes it even worse is that the MC is some type of powerful Noble who can pretty much do whatever he wants, so there is absolutely zero thrill at any of his transgressions nor is there any sort of taboos that are being broken since everyone seems to just go along with what he wants anyway. Boring. Boring. Boring.

The only reason why I am giving this travesty 2 stars is because it's at least comprehensible and the translation is decent, otherwise as a work of erot*c fiction it's severely lacking in everything. <<less

This is the kind of novel you show to haters of Japanese novels to say "Hey, they're not all like that!"

The protagonist reads like a real person. The harem isn't your typical Japanese harem either - the main character's status and power are vastly above the people he meets, and his behavior (and the behavior of people around him) reflects that.

At first it looks like it will be focused on the le*d bits, but there's a lot of politics and war for the main character to deal with, so he... more>> begrudgingly leaves the bedroom to deal with his family's enemies. The politics and war make sense too, it's not just thrown in there to show off how amazing the protagonist is. And he is amazing, even though he's not perfect.

The only problem with this novel is that it updates really slowly. There's plenty of content there already but sometimes it takes more than a month for a new chapter to come out and I want to read more already. : ( <<less

The first 170chs are 95% s*x and 5% politics/worldbuilding. And it's good for what it is. The sprinkle of politics is just enough to keep you interested in anything other than s*x.


Arc 2 is a major tonal shift. Now 80% politics and 20% s*x. He goes an entire arc in the capital with only 1 ass grab. Doesnt help that nearly every harem member is pregnant...

I think the author wanted to tell a story instead of just smut and it's pretty good by JP standards. I like how he skips events for pacing and characters feel goofy but not flat.

PS. The ending of arc 2 is really sweet and had me pretty giddy for a few days.

A novel for men of culture (͡° ͜ʖ ͡°)

Very realistic and strangely not overly sexualized s*x novel, the descriptions are enough to be interesting but not too long nor too cumbersome, the story follows our MC as he reincarnates in another world as a noble and his journey to assume the responsibilities and (most importantly) the benefits of his position

As it is a feudal society people accepts the MC as a wielder of social power and this is amplified by the strong magic nobility tends to have, which... more>> gives him plenty of room to maniobrate and have his way with women, its very amusing to see how he leverages women using his money, his authority and his magic power which keeps the story fresh

Is also interesting how his relationship with those women evolve as their circumstances change, overall is an excellent story and definitely a nice change of pace after those generic isekais, frankly, this totally deserves to be adapted into hentai manga

And yes, there is also a typical fat noble bastard, a pretty nice dude (from the MC's point of view) <<less

Many reading this don't understand despite how the title said it all.
This is a "LASCIVIOUS STORY" of the marquis's son (MC).

Despite all that said, some ignorant peeps mentioned how the females are there just to be f*cked, lack of character stories aside from the MC, criminal-like storywriting, MC is not behaving like a beta veggie saint, only MC POV, yada2, and some other bullshit.

I say this again "This is a Lascivious story of the marquis son (which is the MC, and is why the story is being written from MC's perspective) "

You read this like you enjoy ero-doujin, with the positive side there are more continuity and plot compared to a short ero-doujin. You don't expect grand plots and amazing character development in this kind of story.
Not to be mistaken, THERE ARE GREAT plots and character developments in this work. Some main Female characters are also revisited many times in the future to progress their plots and developments, but it does take some time as the MC cycles between them. Some readers are just simply not patient enough to read far and give their verdict early.

Treat it like playing an ero visual novel with good stories to tell, and is not straight nukige.

If you don't nitpick, the plot is entertaining.
And if you have read many, you know that this story is not common among many other JP LN/WN literature.

Update c223:
More world-building, nobility complexes and politics are being introduced.
Some might complain about how the erotica amount is being reduced.
Personally, I enjoyed those chapters that progress or add true content to the stories, the author paying attention to details in nobility conduct and its world-building are big + for me.
The writing style is also smooth and helps to enjoy the stories. (I'm mentioning this, since some other WN/LN writers tried to introduce politics and world buildings in their writings, but due to their lack of experience or skills, only for it to be a pain to read at.)
Overall this turns out to be better than I initially thought it would be.
The 2 newly introduced main heroine,


Orshian gave me some entertaining laughter when I read it.

The Spierzieg princess buildup is worth it and the author uses it extraordinarily well for her introduction chapters. Kudos to the planning and writing skills


Update c262:

The end of another Arc. Buildups are used properly with well-thought-out plans, foreshadowing and plots executed interestingly and satisfyingly. 10/10 for this arc.

So, I tried this one out because it's R18 and I don't usually mind an Erotica WN that has a tr*sh protagonist under certain circumstances. Being no yaoi, ntr, scat, urination, futa, etc. That kinda gross stuff. But this is really heavy stuff, man. It's all his pov and never the girls. Most of the girls are just straight-up r*ped without any consideration for them at all. No tact or anything. No subtlety? He just r*ped them and it's just boring because they aren't even into it at all and... more>> that's made clear. You have to have some heavy taste for that. Then he made out with the girl right after jizzing in her mouth? Described the taste and smell of his own cum. 😆 Yeah it's a one star, mate. <<less

Only read this if you can don’t mind

  1. Rape
  2. Tons of s*x scenes
  3. as*hole and manipulative MC
If I had to describe the MC’s character, it would be that he’s a typical noble. Neither evil or good. He abuses his power to get what he wants, but at the same time he cares about the people close to him and also does his job well. Somehow I find him really charming as a result.

One thing that surprises me about this novel is that it’s actually really written considering it’s an R-18 that’s saturated with s*x scenes. The characters all feel real and fleshed out. The story flows smoothly and is just an enjoyable read. There is plot development and world building in this novel, but it’s very slow, and the focus of the novel is more on the slice of life aspect.

Overall a good casual novel, if you can turn off your moral compass and accept all the evil things the MC does.

I like the fact the MC accepts the fact that his new life has changed him and does not cling to some morals of his past life, or just decides he will do "whatever he feels like" in this new life. I like the characters and of course the echii scenes kudos.

Pretty amazing novel.

It's not just ero stuff happening, the world building is great and its more like a Isekai with political wars with the ero stuff to spice it up.

Yes it has some heavy stuff, you don't have to like that, but that kind of behavior from nobles is something pretty realistic, just look at human history.

... more>> It's also pretty idiotic to use our current world morals to judge a fantasy story, if you can't stomach certain things, just don't read, the tags are there for this purpose.

This novel has a lot of chapters but the previous translators abandoned it, I'm glad someone picked it up, thank you and please don't drop it >.< <<less

Update: love the novel and I'm glad that a new translator picked this up. The old translator had a 3 months pause, with some promises here and there and then dropped it after 6 months or so. I highly recommend this and wish you all can support the new translator to speed this one up. Cheers.

A relatively decent R-18 novel, the MC is a villain, and he doesn't hide it, but overall he doesn't go around attracting trouble but only goes out for women. That aside, the plot is... more>> well thought out where the MC has a good head on his shoulders, and in-depth but casual political issues are now and then but s*x is the main theme (obviously). I must applaud the translators/editors as the translation is impeccable and no thoughtless interruption in between every paragraph. Give it a go, a much better R-18 Novel then most of the rubbish we already have. <<less

My favorite isekai by far for many reasons.

While a commitment, I suggest people read at least all of volume 1 before deciding on whether or not to drop the series. The early chapters don't give a good overview of how the story is in it's entirety.

As for the main reasons this series stands out for me, I'd say the author has done great with the setting and world building. The background of the story adds a lot to the h-scenes and relationships with the heroines.

One other aspect of the story... more>> I've come to enjoy is the culture clash the MC experiences. It's highlighted much more in volume 2 than it is in 1.

The MC has adapted well to the world he's found himself in and has crafted a persona that fits the environment he lives in almost perfectly, but of course he can't let go of his cultural roots from Earth entirely and it seeps into his behavior sometimes.

It's very enjoyable for me to read the perspectives of other characters in the story and how baffled, amazed, or uncomfortable they are by the MC's actions, and how they react to and interpret them. What sometimes seems relatively innocuous to the MC is in fact a very big deal to people in his social circle and of similar social standing; so much that it actually affects his relationships with major characters.

The biggest hidden gem on the site imo. <<less

The novel is pretty good, one of the first R-18 (ero-novel) I read but I quite like it, that it has a lot of worldbuilding and even though the story is about s*x you feel like it's in a real-world and I think the author is pretty good

I think it's sad that a good story isn't available for everyone (not fully translated

The reincarnation has no actual effect on the plot that couldn't have been accomplished by saying, "he's a genius", so I assume that it is merely the author imagining himself as the MC. The story itself is simply R18 smut about a young noble abusing his authority to r*pe women. But it never pretends to be anything it's not either. No phony justifications, no ridiculous motivations, just r*pe smut with a h**ny MC. Read if you like, don't complain if you dislike. Loses a star because of information-dumps.
