High sexualized, highly assertive monster girls with superior physical (and maybe magical) strength to that of a human or specific monster characteristics which give them a district advantage in their pursuit of men, who are a highly desired commodity amongst all competing monster girls in the universe of the work. Most relationships between monster girls and men is a predator-prey relationship. Men, being the prey, cannot hope to meaningfully combat these creatures as the creature's specific evolution gave them a distinct advantage, it would be like a fly trying to defeat a Venus fly trap, a creature specifically designed to capture and feed off of flies. As such, men exist only as slaves, cattle, semen tanks or otherwise unwilling companions of monster girls who continually feed on their semen and/or use them for sexual pleasure/reproduction.
This interpretation is contrasted by more 'lovey dovey' or waifu type monster girls with a wide range of quirky personalities, especially if it consists of an equal partnership, who are less likely to be on a cold-blooded quest to capture and rape men, but more likely to be seeking a traditional husbando.
I think your analysis of KC might be a bit off then.
The monsters are definitely high sexualized. They aren't really all highly assertive.
The ones that are assertive are super assertive, but there's quite a few that have reversal conditions. AKA "do this and that and she'll be your submissive slut."
Orcs and orc chiefs for instance. They can take the lead or be super submissive cumdumps that are ok with whatever their master wants.
The redcap is also like this where if she gets horny her head is red but she turns demure and passive when that sex drive is fulfilled.
It'd take a while to go through all of them but a lot of monsters have reversal conditions.
In fact I think all the book 3 monsters have one.
Some are just full submissive, though to be fair some are also full dom.
Men, being the prey, cannot hope to meaningfully combat these creatures as the creature's specific evolution gave them a distinct advantage,
This though I think is your biggest misconception.
Heroes exist in this world. It's a fantasy dragon quest style world.
While the monsters are strong, humans are
also powerful due to the advantages of magic and fantasy weaponry.
Dragons,
who are another submissive type of monster, are cocky and look down on others. They will only take men capable of beating them as husbands, but when they do get husbands they wait on them hand and foot, giving them full access to their treasure. Fact is, that means people exist that are capable of defeating them in that universe.
especially if it consists of an equal partnership, who are less likely to be on a cold-blooded quest to capture and rape men, but more likely to be seeking a traditional husbando.
I think this is your second biggest misconception.
Some monsters are like this no doubt. Like sharkgirls for instance.
But Kenkou is actually pretty obsessed with classifying the relationship between monster and man as "husband and wife." He uses the terminology often. In most of his entries, he refers to the monster's mate as their husband, and talks about them searching for a husband and what not. Not prey or sexual partner. But husband.
In fact the battle system for this game is designed around an "equal" (hmmm more like male leading tbqh) relationship from what I can see. It's battlefuck. You don't get one-sidedly fucked in most battle-fuck. You fuck back. If she takes the lead, that means you're losing. In order to win battles you have to please her sexually to the point that her love points are maxed before yours. Becoming allies with them means making them subservient to you in a sense.

I'm excited because I like KC's design sense and he comes up with interesting scenarios in MGE. The dominant girls are also all really hot and I hope he includes my favorites. I hope they take their time designing a good battle system.
