I originally read this novel because I was looking for romance, fantasy, and swords.

I didn't expect to like this novel as much as I do now. It starts off pretty well in the beginning but somewhere in the middle all there was... well was s*x scenes. But once you get passed that the story is actually pretty good. Was good for the laughs.

Although there were some really weird s*x scenes, the translator is kind enough to say if there are any particularly weird fetishes in the chapter.

The reviews on this one are really misleading. At first I thought ok they said there is slightly any R-18 scene it seems to be fantasy so why not? I am at chapter 21.. And there is ONLY s*x scenes one after the other with different girls and until now there is 0 plot or story. I won’t say that they are badly written or that the characters aren’t enjoyable.

But don’t be fooled, if you want a novel with a story even a little inside, pass your way.

Dropping at Chapter 65

Okay start, MC dies and go to another world. Then he meet the main heroine (tsundere) (Don't really know why he likes her). Become kinda like a man s*ave to the main girl (don't know why)

The plot of novel isn't really good. Basically a fantasy game based novel with s*x. The world building isn't interesting: So far the world is stuck in the Royal Capital.

MC lacks a goal. The only thing he thinks about is "I'm glad I died"....

A ero novel with content besides characters constantly having s*x. Probably the best ero novel on the website. Good thing translators are understanding that reading ero novels where the characters constantly have s*x is boring.

One of my guilty pleasures. Decent story and decent s*x. A great mix. MC is somewhat perverted, but the girls are not naive (they know and understand what they are getting into) and s*upid (well the main Heroine may be an exception hehe) nor are they forced to do anything they do not want to do. Do as the Romans do so they say, and the MC does it well. I have read other R18 novels and the typical theme is the MC is a douche bag scum of some... more>> kind and takes advantage of the girls. Here it is consensual and fun to read. No hypnosis, no mind breaks... just regular fun relationships. It is Harem and it is consensual.

Action is there as well. The MC is OP with his cheat but does not want to draw attention to himself of the famous kind... well you have to read it to understand why, the H scenes are not abundant and not as descriptive as other R-18 novels and leaves some to the imagination at times. Enjoyment factor 5/5. <<less

As usual with all japanese novels, the MC is a virgin who is given a certain cheat by god. Our MC has the ability to create strong weapons/armors. After his reincarnation to another world, he saved a girl by using the weapon he created to slay a dragon. Then for some reason or another, MC chooses to live a relaxing life without gaining the attention of the country by acting as the s*ave of the girl he saved. It's all fun and games until he could not tolerate the insults... more>> by the captain of his squad towards his master. His ideology of not gaining attention is by sneaking into the captain's room and blackmailing her by screwing her ass. All females are easily dominated except for his master who can easily make him cum. The only thing in the novel that is well known is that he loves his master with reasons unknown and therefore he needs to sexually punish those who insults his masters. <<less

If you are into clueless goalless and non empty MC this is the novel for you. He is slaving himself away with a reason he is not even clear, he doesn't have a pride as a man at all. He can dominate all other female but for some reason Asuka can't be dominated. Putting aside s*x and other play like other Japanese novel MC seems have no self confidence. If you put his ability together he can dominate the world but for some reason he is not even qualify to... more>> be with the lowly Asuka which he boosted with his own power. For god sake he is having the ability gifted by the god in person. If I can continue writing where the author left off I will let lightning strike him 9 time to reform is the first thing ill do and second ill throw him into dungeon or deep dark forest to make his personality a bit better and let some other character beat him senseless and humiliate him so that he can respect and pride in himself. Author do something to man him up not in bed but in real life. <<less

Quite unexpectedly enjoyed this one mainly because of Thunderbolt. She's very adorable and quite a bit innocent. I don't understand why the main guy likes Asuka though. No impetus or anything for him to fall for her. Heck, even Captain Risty might be a better "Master" for him. But he still chooses Asuka because of "love". There's not enough explanation or reason for him to feel that way for her so it's unsatisfying.

There's plot progress on the side besides the ero scenes so you don't really get bored. There's enough... more>> mystery to some characters too (like that narcissistic hero they met on Arc 3). It's not a bad series but not something you'll regret missing to read. I skimmed through some of the ero scenes though.

Check it for the ero or if you're bored and have time.

NOTE: I want more Thunderbolt! <<less

I guess I would probably not rate this story as high, if it was a normal one... But for a Genre based around s*x and sexual interaction, the story is surprsisingly good.

Well, simply story-based I would at most get 4 Stars by me, perhaps only 3 1/2. But considering the focus beeing on interc**rse, I have nothing to aruge about, since it is well done and there are very few other stories that that even bother with a decent story once they settle on s*x.

To sum it up, this story... more>> is sexy, funny, with decent character-development and interessting characters on the top. Well, the combination of all virgin-like characters with no experience in this regard makes some things kinda funny... but it is fun to read non the less.

If you want to read matue-sexual content with a story beyond the sex, I will reccomand Azura everytime I am asked. <<less

I like how almost everything is considered a weapon or armor even though they clearly aren't. Great story with the male lead standing at the rear, creating godly weapons for his girl hero harem. Fast and consistent releases but slightly short chapters. But the R-18 isn't even the main focus since it has fighting and peerage and much more. Great novel. Highly recommend for avid mature readers.

The Novel is good, MC given a super cheat early on that allows the MC to do what ever the f*ck he wants. The almost non-existent romance between the first heroine develops slowly (because hes usually busy trying to f*ck other girls first) but there is progress. Also did I mention that the MC likes to think with his d*ck most of the time? WELL its not that severe but theres still that, hes also quite the pervert although a closet pervert. At some point the MC learns his cheat... more>> is not all supreme and he learns that the hard way (by getting beaten into submission by a dark skinned loli) so theres also that. All in all its a good read if you’re looking for some material to fap to but don’t expect something as extreme as [FIT] or [Charm]. <<less

Since I didn't read much, I don't have notthing to say about the story. I just love how author simplifies the usual reincarnation process (sudden death - god saying sorry - giving special ability for compensation - again giving special ability for compenstaion - again... - reincarnation). I do love reincarnation/transported to another world stories but it was always a great pain to read MC going through this usual process again and again

For a novel that has R-18 content as its main allure, the story is interesting enough. The characters are somewhat unique and likable and the more delicate parts arent overly embarrassing. Certainly one of the better nocturne novels out there, and one of my personal favorites.

tr*sh, complete and utter tr*sh.

To be honest this would actually be a decent read. The smut is varied enough to not get boring and it's fun to see the reactions of the girls. There is basically 0 world building or any kind of plot but hey this is smut pure and simple it doesn't really need that other stuff.

Yes this story WOULD have been fairly enjoyable except for one teeny tiny little problem: The Protagonist

The protagonist of this story is SO bad that it renders the rest of the story... more>> pointless, as in this story has no reason to exist. Almost every other isekai LN is better than this in at least one way. There is nothing this story does as good or better than 100s of others and it feels like the author wanted to make the most worthless MC possible just to see if he could. He stutters during every conversation even if it's about the weather. He goes deer in headlights mode almost every chapter any time the slightest curve ball is thrown his way, sometimes he does it during perfectly normal conversations. He scratches his damn cheek so often it should be a fracking hole! Heck the line ' "Eh..." spilled s*upidly from his mouth' is sometimes used multiple times in a single chapter and I swear there must be 30 or more similar lines in just the first volume, I think the MC says Eh more times than there are chapters! Shinji Ikari is a more well balanced and normal human than this waste of oxygen. We can't even just enjoy the fact that he's a badass politician or fighter because he isn't a badass anything! He isn't even average. If he wasn't gifted a god tier ability he wouldn't even qualify as generic villager #32. Without his cheat ability his story would be 'got teleported to another world and he... existed' he has no goals to work towards nothing he wants to protect or accomplish he doesn't seem to even notice his mountan of issues so he isn't trying to be a better person.

TLDR: The MC doesn't have a reason to exist therefore a story about him doesn't have a reason to exist either. Go read something better. <<less

This could have been a pretty good light read while laying in bed before sleeping. The translation was pretty good, but more editing could have made it much smoother. I hadn't noticed at first, but the fact that the author's plans to continue writing are unknown, I stopped reading at chapter 28. After almost 3 years without an update, I think it is assumed to be cancelled. No reason to continue reading in that case.

Honestly, it could've been so good if the author had focused more on the plot than the s*x. Don't get me wrong: I love me some hentai. But this stuff gets a little too kinky even for my deplorable, disgusting tastes. And it just never stops. Two-thirds of this entire story must be shameplay. Not all the s*x is bad but Christ Jesus all that shameplay is just tiring. Not all the s*x is bad, it's just that it pushes an otherwise interesting story to the background.


I am genuinely surprised this never involved scat. Though, if body hair fetish grosses you out, this probably isn't for you. An*l hair. Also pee.


That said, what is it that made me read this far? Okay, tsunderes annoy me to death, but I do like the character development when it happens and that little bit of story attached to all the p*rn as an afterthought really charmed me somehow.

That's what gives it a three for me and not a two. It didn't deserve a four and a two wouldn't be fair to the parts I did enjoy.

Surprisingly good story for an r18 novel, and it barely has any s*x scenes, really have to commend the author on this one. I would be interested in seeing a published version of it, but I doubt that will happen, unfortunately.

The novel would've been great weren't for MC tr*sh personality and he's issue with women he messed with without taking responsibility, I drop this novel when

thunderbolt and asuka duel because of MC

kinda drop after that duel, I hate the MC letting the girls say some bullsh*it on " it ok if u dont love just dont leave something like that " along that line, he never takes responsibility he just let the girl confess after he's done toying with them...
