Definitely not for children

This one starts out really stupid, trying way too hard to be funny and not succeeding. As things progress, the juvenile humour does have a few amusing moments, but the sluttiness of the sidekick characters is as much a test of patience to mature readers, as it is w***ing material to immature, teenage boys. Obviously, if you're all grown up, you're way less likely to enjoy this.

At some point, however, an actual story springs seemingly out of nowhere and, lo and behold, it's actually really good! There are evil villains, the MC is a wholesome beauty and it all kind of feels a bit like the classic, Ninja Scroll. To be honest: for a while there, I was really enjoying this.

Sadly, the author remembered that this was supposed to be a sex-based gag comedy, and he did really beta move st like having the female characters all engage in lesbian group sex. I was close to dropping it, but it happened so near to the ending, I just wanted to see the final battle. Things wrap up nicely and it was 3.5, with a 5/5 for meme potential... but then, during the extra chapters, there's drug use, more lesbian st and, the absolute f**ing no-no: paedophilia. Luckily this doesn't actually occur, but to even have a 25 year old bunny-eared bitch lusting over what look like little boys - and right after another bullsht lesbian scene - was an instant drop.

Of course, wkers were still w*ing and pretending all this s**t's funny, but if you're not a basement-dwelling gamma male who thinks dykes are cool because it's the only way you can think of satisfying more than one woman (still too immature to know that a real man only needs one woman anyway), you'll probably get sick of this eventually too.

I have to reiterate the meme potential though - this has some of the best panels for that purpose you'll likely ever come across.

Just a basic story full of ecchi and memes, if you don't find those amusing then skip this.

There are about 20 characters total, 4 of which have a regular point A to point B character development which would appear amazing if you are used to trash tier isekai, but only average if you have read any book or seen any good movie in your life.

Overall this is a lot better than any isekai/reincarnation/regression manga published nowadays, but nothing amazing and the constant ecchi nonsense can get tiring after a while. The artwork is cute and the action and facial expressions are well drawn.

If you have time to waste you could do worse than reading this.
6.5/10

Chapter 78 is such bullshit
Chapter 88 was really nice, however it felt like her development was somewhat very abrupt, like bouncy ride. Rather than a smooth ride for her to have her emotions be present on the surface

Overall, really nice read, but i most likely wont read again unless i want to have some few laughs. Like the manwha is meta and funny

A Masterpiece

And thus, one of the greatest R-18 comedy mahwa has come to an end. If the raunchy scenes and NSFW-based plot elements of the story won't bother you, then do not hesitate to read this, it'll be one of the best decisions you make in your lifetime.

It starts goofy, then goes heavy on the plot and will sometimes leave you on the edge of your seat. This is the series you will want to, but can't recommend to your normie friends.

I only wish that I could rate it higher than a 10. I'm already excited for the author's next work and the spin-off chapters he mentioned in the afterword.

Edit: Forgot to add this when it first ended, but the epilogue/side story was just as good, albeit with a bit of a rushed conclusion. It ties up loose plot ends and adds some good worldbuilding. Still 10/10.

An amazing story, hilariously masked with sex references

This is arguably one of the best stories I've read this year and I'm leaving a review to address the criminally low score.

Let me tackle the elephant in the room - the ecchi, it's quite omnipresent and at the centre of the story. I read it as very much tongue in cheek, a great satire to all the other "you won't belive it's not hentai" adventure stories. If the crass humour is not your cup of tea, this story is probably not for you.

Beyond that, you'll find a very well fleshed out (pun intended) world, with deep characters and motivations. You'll find layers of machinations and centuries of scheming. There are also amazingly choreographed fight scenes and sensible power levels.

As of chapter 80, I'm really enjoying all the revelations to subplots and can't wait for the upcoming battles.
