2 volumes read at the moment of writing this review.
Let me state something first. I'm reviewing this series not as a regular ecchi manga, but as a hentai. Because yes, this one clearly trespasses the boundary, and despite being censored, a lot of things are clearly showed.
The plot revolves around Daisuke, a man who is transported into another world (yay another isekai...), where he is finally able to accomplish his most desired dream. To be the monster girl harem king. Yes, you read this right, he goes around the world banging with all sorts of monster girls. He's also a biologist, so he takes the

TL;DR: Copious amounts of seggs with a taste of red pill.
Meandering about, is a subgenre of Isekai that I thought of, in which the entire story is the author stroking themselves out the little nuggets of information they collected. I'm not opposed to half slice of life, half fantasy (masturbation) works, but very few of such works are worthy of people's time. If you couldn't imagine a work in this sub-genre, just give the "smartphone" isekai a read. That's the one. This, however, is one of those rare gems that's actually fun to read. Let's start by addressing the controversy regarding the so-called "sexism". Somehow, ...

Was doing fine enough until the mangaka revealed their hand on how much they hate feminism.
From the top, man gets isekai'd into a world of primitive monster people and decides to build stuff for them without making 4 certain technologies that are commonplace in modern day because the mangaka wanted a writing challenge(literally says this in volume extras). That is half of the manga. The other half is pure hentai, way past ecchi. Lots of boob and lots of loli in every chapter. The manga is at it's best when it is a pure hentai that is describing how these creatures biologically exist rather than ...

The most compelling and engaging ecchi isekai I've ever read. Strongly appeals to readers with a STEM background. A lot of time is spent on explaining the intricate biology of the various monster girls and the new technology introduced by the protagonists. Yes, there are two and I really enjoy the different experiences and perspectives for which this allows. Starting in Vol 4, contains some hot takes critiquing modern feminism which are a turn-off for some, but I personally thought were done in good faith. It wasn't enough to "red-pill" me, but I thought it was fascinating to see what that side had to say

It's a typical ero isekai with a fairly flushed out world. Each demi-human tribe is given a few chapters to flush out their lore, biology and also have the main character help them with a new technology (which is given very informed detail about it's design and purpose). Art is fairly good for monsters, environments and armor/weapons, but character designs feel somewhat generic and same-y. As of writing I managed to get 43 chapters in, but the general formula is pretty predictable, with the primary protagonist discovering a new group and mating with one of the characters after saving the tribe from some impending doom.

Wow. What a weird mixed bag. Starts out with a frequently creepy protagonist caught between sexual narcissism, scientific amoralism, cringey nerdism, and bouts of common decency. Extends into an intriguing setting which more than supports itself without smut. Diverts into plausible xenobiology and 'How It Works' pages that actually apply to the real world. Then it jumps directly down the unpleasant rabbit hole of "Jesus F. Christ, when did Ayn Rand start writing H-manga???"
This is a really good milieu story with one or two genuinely unexpected twists. Now, I'm not *complaining* about the sexual content, but to me it ... |
