The MC is great. I'd be very okay with it expanding into a story outside of just smut. But the story is true to itself, and that's not a horrible thing.

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 sex. 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 virgin 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 sex.

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

One of the top novels for this year in Japanese raws. While there are some rape, 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 rape, 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... more>> 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 Incest 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. <<less

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.

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

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

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 lewd 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

Good Story

Aristocracy Complex

Smart Protagonist or Genius in that world

The R-18's entertainment is also good

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 slave who obviously needs some training and breaking, he also finds out that her mother is a slave 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

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 horny MC. Read if you like, don't complain if you dislike. Loses a star because of information-dumps.

This is my first review. Good smut and interesting plot. A pretty realistic depiction of powerful noble family with absolute authority in a medieval high fantasy setting. World building doesn't happen until ch 15.
