At the point this review is written, the raw is at c161 with 1, 602, 879 Japanese Characters. Also it's daily updated, so I doubt any translator can catch up to it... But I wish they could, because this is probably the best true adventure novel in Narou

It's extremely detailed, you don't know what will happen next, hell, you don't know who are the heroines.

It's amazing. Try it~

What could've been a good reincarnation novel ended up getting ruined by standard WN writing cliches. While this refreshingly did away with truck-sama and a mysterious God who manages reincarnated people, there was no rationale as to why the MC reincarnated, why he could literally choose OP cheats, how he was so calm after rinsing transmigration etc. I'm not sure if it's the original wiring or the translation, but most of the chapters are filled with useless onamatopoeic romanji that add nothing to the plot. I'm here to read a... more>> novel, not page after page of sound effects. The plot is hard enough to follow as it is. On top the race names are confusing as hell. But what really does the novel in is how the MC gets used to killing so easily and the rate at which he acquired absurd skills. <<less

- The Game Elements are done well, it isn't until much later that he gets an item that replicates an 'inventory'. It has been confirmed that there is an 'identify' skill, but the MC doesn't have it.

- A vast world filled with several types of unique magic and abilities. Various gods are well explained.. Makes me want to read more!

- Good mystery set up from the start. The story is told very naturally, the MC moves on his own devices but you feel like something is going on in... more>> the background.

- The 'black cat' is a misnomer, it's actually a super panther when it fights. The cat does not speak or control the MC with suggestions. The MC promised loose goals to it, but that's it (very loose goals with no timetables lol).

- The fighting scenes are really well done.

- MC is strong and his race is OP (literally Lucifer) but he isn't instant-OP, he needs to work for it and he can die if he's not careful.

- This is a small detail I liked, his race is 'Lucivault' and he has a tattoo of a cross of light that's covered in chains.. Idk.. Symbology or something.


- The first 24 chapters are terrible to read. The translator works super quickly but didn't get an editor until then, and it shows.. I know the editor said he's working on old chapters (to be fair, the editor is really.. Really good) but for now you will be pulling your hair out sometimes.

- There really is no rational for why him (or others) are able to transmigrate to this world. The world is set up explicitly to stop gods from entering it. Unless there is a major explanation in the future, this is simply convenience for easy plot sake. Especially when you consider the god/being that brought the MC to this world gave him the ability to choose any race+4 unique awesome powers regardless of how those powers worked with that race. (For example, he could have choose to be a water spirit with fire powers)

- Like all Japanese novels, the MC is super.. Super unrealistically friendly to women. I get that women have vaginas but this MC literally tells a female assassin (aiming for him) that he loves her after knowing her for like 4 days with VERY limited interactions.

- With few exceptions, all notable characters are women (ALL notable humans/elves are women). I guess it's possible but how likely is that? I feel like this author is going to make the MC, who is reasonable is every-other aspect, someone to only have women companions or something.. It's annoying. (Oh, and there is the trope of western looking woman fawning over a self-admitted bland japanese dude)

- He is fixated on being an adventurer for no real reason other than "it's just the thing to do". The MC is not as strong as an Elder dragon or something, but he is strong as a S-Rank adventurer (at least s-rank maybe even s-rank+, he hasn't been pushed yet except by his master). The world is in turmoil and he is already Immortal (not invincible, he just wont die from aging) - I do not see what is stopping him from making a base already.. HE ALREADY CLAIMED THAT TO BE ONE OF HIS GOALS!

- The BIGGEST con for me is the name of his race. It is CLEARLY Lucivault but the translator is keeping it Rusivault. It should be Lucivault because although the MC is a good person, his power most resembles *Lucifer*. It just makes sense for his evolved form to be Lucivault, not Rusivault.

- For the last 10 chapters or so (chapters 43-53) the plot has become incredibly annoying with the women aspect. The MC can not meet a woman and not mention her breasts and that woman can not help but to immediately spread her legs for the MC (all while acknowledging his bland Japanese face - 'bland' is not my word.. It's in the novel). The author set up an incredibly intriguing world but HALF (at least) of the dialog since the MC has made it to human lands has been about women. <<less

I never really write a review, but because there was no one who reviewed this series with great potential I thought why not. (Sorry for the clumsy writhing in advance). This series seems pretty good. I don't really have anything to complain about. Well, the MC is transported to a room where he has a choice to be reincarnated or not. The prologue was done pretty unique with its description on how the process of the whole reincarnation is done. It has an interesting story thus far, hopefully it stays... more>> this way.
The MC also has a choice to choose his own race and 4 skills which are pretty interisting. At the moment it hasn't really gone indept to the world building because the MC is still somewhere lost. So no new characters introduced, so hopefully there will be some unique and interisting one.


It started good, but got downhill really fast. The only thing I liked was the process of his reincarnation. It just seemed so myterious compared to other isekai novels with the usual god needs his help or oops god made a mistake, so here new body, new world, enjoy. <<less

Well... to describe my impression of this series after reading 50 chapters, I would say that I am disapointed.

Allthough reading this novel in its early chapters felt a bit boring but it got better later on and plot seemed interesting, however it suddenly chanced after Shuya got into contact whith women. Story itself started to circle around of boobs and butts, missing the bigger plot.

So... yeah its not a novel to my taste anymore and I will drop it, because if I want to read about ero things I will... more>> read novel specified of them, not something that feels like some teenager horndog wrote it.

I am giving a thumbs up for the translator & editor though. Allthough the novel let me down plotwise, its guality is great and translator & editor comments are hilarious to read ^.^ <<less

This series started out with promise; the main character had an interesting quirk, and his starting point was good, but after he got done with training his new skills and headed into inhabited territory, the author turned him into a sex-crazed maniac and started spending more and more time describing the female characters' breasts, at which point it just started feeling like another wish-fulfillment story. This isn't a bad story by any means, but it's lost whatever it was that kept me reading. It's up to you whether to give... more>> it a try or not. <<less

Firstly the story is pretty stupid and lame. Seeing a bunch of reviews I decided to finally add my own. This story is only for reading when waiting for an update. Lots of potential is instantly shat on by the author in the same chapter. Foremost example he is a vampire... immune to the sun and without weakness why the **** even bother then? Now lets go on a limb and say a vampire not in the cliche sense but just the literal parasite kind... NOT EVEN THAT he don't... more>> require things from others and can get by on normal food. He is literally not a vampire in any context. He is a pervert. He is not smart at all and just forces through problems. He never has any problems. His life is never in danger so no tension ever. The potential of the cat is never made use of in a interesting way. He is a thirsty pervert. The best parts when reading this are the tn/ed notes/comments. Too many skippable parts of no noteworthy note in any possible conceivable fashion (eg. sounds or useless over extended rambling)

Overall not the worst thing you can see on NU not by a long shot. It is an alright read. I recommend giving it a go if you are bored, taking a poop in the bathroom, waiting in line and so on that kind of thing <<less

Shuya's an effin weirdo, but gets the romance (if you can call it that) going pretty quickly. But all of this is after what I'd call the prologue chapters, which takes a while to get through, since each chapter is pretty long, almost triple of what you'd usually see.

He might be OP, but he does work to get there, and his approach towards the world arround him is kinda refreshing.

The translation is pretty good, though there are some weird word replacements here and there.

The weapon of choice is rather unique... more>> for this type of story, but so is a lot of other things.

I hope this one doesn't start going downhill any time soon, though it probably will. <<less

I lost faith/respect in reading this novel ლ (ಠ_ಠ) ლ see. The author adds too many unnecessary details like strange sounds and useless tsukkomi. If you could erase those then this novel of having chapter 400 can be condensed to 120 chapters at most. The first translator is exceptional at translating but they drop it cause I feel they are irritated by the foolish MC complaining about being a vampire but he chose it himself so why he complains and be over dramatic about it? Then the second translator comes,... more>> there's a saying that "A wise man learns from the mistake of others and a hard working man learns from his mistakes and a foolish man never learn from others and his own mistakes" this second translator never improves on translating, every chapter has missing letters, missing words, not knowing how to place 'deteminer' 'preposition' 'verb' 'past tense' 'future tense' 'present tense' properly. I mean its basic of the basics of english language and he writes english on his announcement so why he is always having multiple grammar/sentence errors?

Next one is the story - Like most japanese novels that has Isekai. It starts good but japanese authors have a weird disposition of not being flexible/versatile/open minded. They are always stick to one personality of MC and never develop or improve it. First of all there are too many unnecessary stuff put together which can be summed up with few sentences or can be omitted. The way the story telling goes is quite abrupt For example: The dark beetle is mentioned when the MC is almost complete at his training. His master mentioned the dark beetle and then after several sentences there the recently dark beetle that is nowhere to be found through out 1 year of his living there just abruptly/conveniently shows up for some unknown magical/b*llsh*t reason. The events are quite fast paced but you won't feel it cause there are too many fillers and weird sounds that put into words in this novel. It seems like the world is at a stop time until the MC appears and everything will magically appear and be there after being a brief mention of it. Kinda sickening way story telling.

MC - It seems okay at first but becomes overly perverted at 25+ chapters. I hope the author won't d*e from heart attack from his excitement writing this. It's almost all of his fetishes are laid bare for all readers to know and read. Kinda weird reading descriptions of all girls having small mouths, kinda pointless to me if they all have small mouths as description. Also thanks to MC's description of dwarf zaga which has "He has a short build just like a normal dwarf" thanks for the obvious pointless description I know that he is a dwarf. The MC fights half ass all the time. His abilities are under use, he didn't use it to end the fight quickly and every fight he seems to be cornered, even though he has superior abilities he didn't use it. When someone he knew dies he over reacts, though it is his fault cause he didn't use his abilities early and he knew the enemy is a superior dragon (what a stupid fight scenes, maybe the author loves drama?). Also the MC has a tendency to watch the fight first and watch someone dies then act late so that he has the spotlight.

I kind of tolerate authors b*llsh*tting their way through the stories but please give a proper, logical and believable explanation. Even if the genre is fantasy it doesn't mean you can make up things which contradicts what you have explained earlier. <<less

I was reading through the reviews and in the middle of someones they say:

"I get that women have vaginas but this MC literally tells a female assassin (aiming for him) that he loves her after knowing her for like 4 days with VERY limited interactions."

So perfect. Just let that be the review. Nothing more or less. It alone tells you everything you need to know about this before reading.

This story starts off slowly, but it focuses on training and becoming friendly with the family the Shuya encounters. It makes sense that he trains to become stronger before setting out in the world. The pace picks up after that, and the story has some nice, creative fantasy elements. I love all of the adventure and gore.

However, there are a few critical weaknesses here...

  1. BOOBS. What is with the MC and BOOBS? He literally identifies several of the female characters by their breasts and doesn't pay any attention to the men. If the translation team didn't leave editorial comments in there making jokes about how completely fixated the MC is on BOOBS, I think I would've dropped it long ago. Shuya literally spends several chapters in a row mentioning BOOBS or feeling up women before a chapter shows up where he doesn't.
  2. Shuya himself isn't very smart. Several different events have happened so far where he just OPs his way through them. It doesn't require any clever strategy. He even lets the humans take advantage of him without trying to do anything in retaliation. When women try to kill him, all he does is flirt with and feel them up (this is not always consensual) and possibly have s*x with them.
  3. The start of the story is weak in how it abruptly makes him this OP creature without challenging him to develop on his own or anything. The greatest character development I've seen so far is when he stops trying to have s*x with everyone hot woman he encounters. Although there is a central plot, it comes across as weak and unfocused most of the time. Shuya is taking his time very leisurely.
The highlights of this series would be the cat and some of the side characters. I like how the writer brings attention to Rollo frequently and seriously treats her as... more>> a leading character instead of some kind of pet or minor character. <<less

Honestly, the story sounds interesting. The chapters are a decent length and the story at least seems to flow nicely. I normally don't review stories and just leave a rating, unless I feel the current reviews are inadequate. And you know what? The translation quality is bad. No one seems to be talking about it, but the translation is just irksome.

It doesn't melt brain cells like a machine translations, but it feels like none of the sentences have any feeling, and they're all so monotonous. On top of that, there... more>> are a lot of weird sentences with broken grammar and such. It feels like a chore to read this translation. This story is in serious need of an editor. <<less

Hands down one of the best novels I've ever read. Amazing world and world building, superb overall atmosphere, great MC, great and well-developed side characters... I have literally 0 complaints. Like cmon, we are 8 volumes in and I still feel like this is just the beginning of an epic adventure. I mean, I am even considering this to rival Slime (which is my favourite novel ever), but it is just hard to compare these two.

p.s. Do not freak out about the translation. It is a bit bad at first... more>> (but not to the point of being annoying to read), but it gradually gets better, and from chpater 50 onwards, it gets picked up by another translator who is way better. Plus, if you are reading this in the future, chances are that it has been properly translated overall. <<less

Hrm, how to say this... it's a bit hard to think highly of?

Ignoring the TL quality in the beginning and middle, the story itself is kinda... meh. MC is both serious yet always seems to think with his d*ck. This doesn't show much when he's training with his master, but once he leaves it's basically "She's beautiful, let's get acquainted and maybe spend the night." People seem to like this kind of thing, though, and I blame it on all the heavily dense/boring Japanese MCs out there. Horny really isn't... more>> that nice a trait.

If you think I'm making a mountain out of an ant hill, then you just need to read. Whenever MC visits a place, the first thing to be noticed is any beautiful girl. He'll somehow be able to stare at her breast for some indescribable amount of time, and the other party rarely notices, or they have a disposition where they actually like the attention.

I'm kinda scared what will happen when the MC gets himself involved with the slaves...

Overall it's a 3. I'm not that much of an ass to lower the score due to TL quality for this one since the TL does try and get editors and proofreaders, but it's still a very hard read... Meh. <<less

This is a really good story with, acceptable world building and character growth or development.

Though first 25 chapters are very boring, his time in cave is kinda readable but the training arc is really slow paced, and even later on sometimes the author really outdid with the random infodumps and all. But despite all that if u preseve to read from when the story really starts (when protag leaves his master to journey on his own) Things get really interesting, some characters are really fun, but others are bland... more>> like a brick, MC himself is quite decent, sometimes a perv other times a cool guy. The plot is really intresting albiet some filler like chapters in between. Pacing of the story moves from slow to decent to some times a fast paced one. Other aspects are quite good, almost all harem are likeable and an additional star for Rollo the cat, she is so cute !!

But the above mentioned drawbacks are tolerable enough.

Only major problem I have with this novel that MC is like almost every time called "plain" by almost every love interest, one night stand or even some remotely inresting female character, so the author while focus on that MC is very plain looking, however I see that there are countless harem members and one night stand girls and they fall for him too easily, yeah for the person. Whom author repetedly shows with very "plain" looks mostly said by said love interests, eg in a place

Girl (smitten by mc) A: you look plain but u are cool

Girl (smitten by MC) B: your looks are very plain but your muscles are good

I mean wut?, Then author himself explain in later paragraph that he looks plain cause he is japanese, and the world is western like and yeah this occurs a lot of times in almost every arcs, so my main problem is that even if he looks plain but if the girl (love interest) remaind him of that many times then that person should be too rude. And at least that's kind of rude thing one cannot say to one she has a crush on by common sense. <<less

feels like china novel with a lot of clan and guild and drama and clan extermination. I dont know to where author bring this MC story. The goal is resurect his familiar and search something legendary. The pace is not slow and he plunge into one problem to other problem as well with a information gathering first to see his enemy

its really good to read

I quite like mc's attitude, he's not the typical weak dense protagonist often found in a lot of japanese web novels nor the overbearing and offending everyone of the chinese ones ; he's frank with himself and others & in particular concerning womens, there is no sexual content, However it's stated when the deed is done. If he can avoid conflict he tries to.

About this story there is not a lot of the clichés of fantasy web/light novels. Another thing I like is the detailled explanation of the background and... more>> especially the magic system. And rollo is cute.

however I find the devellopement about the vampire race of shuya (mc) a little dissapointing.

I think I said all I wanted to say, I'd give it five stars if the whole 80 chapters I read where as good as the beginning (until fog forest) ; after that point i'd give it 3.5 stars I guess. Let's go for 4 stars as a whole then. <<less

This is the first novel that I enjoyed the most, I mean this MC is a rare type unlike your typical MC who likes to be summoned a certain castle by some kidnapper king. But instead, this MC is stranded by no means full of danger environment until an encounter of fate which save his live.

The story were very good, it is full of adventure and Beautiful women (yeah, it is a very interesting with those mountains and beautiful scenery) (If you know, what I mean).

And, also the MC is... more>> having the Job of a spear man which is also rare. Considering that the typical MC were focusing to be some idiotic Hero with his op power and create his own harem with save the world sticking the Mainstream having a class job of swordsman and Magician.

This MC whose name is Shuya were one of the MC that actually kinda weak at the beginning but as the story progress he changes.

More over, he has his own perverted side too including charmed by the beautiful women on his surroundings but still he is a good guy. He is not a Hero, He is an adventurer that goes by the wind with a promises/objectives to be full filled. As for the harem, the build and development would be by itself through each the story progress and encounters.

In summary, read this novel and enjoy his adventure. (His journey is long and fun) <<less

I'm giving this five stars because I am one of the editors (currently the only one) for Birdy translations and I love it. Although I just picked up the position I enjoyed it before I started. (Working on editing the older chapters 6-30 as we speak, sadly my edits ended up being deleted so I am starting over again.)

Remember this review is my opinion and it should be taken as such. Please read the web novel and see for yourself whether you like it or not.

The MC... more>> is level headed (not when to comes to woman) and calm plus the reason why he was reincarnated is unknown and I like that. He is not the hero or anything. Honestly his luck plays a decent part in why he is where he is for being in the right place as the right time. He then trains to become better over time after meeting his master. He is NOT instantly Overpowered and works his way up. (Still kind of overpowered)

The authors obsession with the female body, how beautiful the females are and that the MC wants to do them them (all the time) is slightly annoying even coming from the editor standpoint. I am hoping for them to use their brain more after getting in trouble at some point. The story is good and the action is nice. I will update that later if is still feel the same way. <<less
