Honestly, this is nothing special at all. It's generic trash but still better than average generic trash because the art is actually quite good and the ecchi is nice and rapid fired. The plot/story is garbage but simple and easy enough to read while laughing at how stupid it is.
Really, it feels very forced most of the time, but we don't expect it to make much sense. The abilities make no real logical sense, there doesn't appear to be a logical, proper system to it all, as if everything was thought of on the spot with zero scrutinizing. There's no real connection between various abilities and we can only sum everything up as "it's weird magic, lol", the power system is simply flippant.
The author just adds whatever he wants and it's at best wish fulfillment. The garbage story is saved by the great art, sexy scenes and actually quite cool chuunibyou scenes/transformations. The super rapid pace and drama that fails to evoke any feelings actually works in its favor because the story, characters and world building are done so badly that if the author managed to make us take anything seriously, it would backfire and be really damn annoying to read.
The protagonist is a real masochistic fool but at the same time he's somewhat likable simply because he lacks the most detestable parts of similar characters, he's actually useful, he tries his best, he ENJOYS being treated harshly and takes no offense to anything. He doesn't mind being treated like a slave or being used. It's pretty much his hobby and he can be "cool" when he needs to. I'm more inclined to being a sadist myself and my favorite protagonists are more in control, intelligent, powerful and scheming, but I can still enjoy the opposite spectrum if the protagonist has a decent attitude about it and is treated like that because he enjoys it. The girls are likable enough that you don't want them to die either.
So, I end up laughing at the supposed "drama" instead, because it's just so silly, simple and forced, so out of place. While I notice out of place story elements and actions all the time, things that make no sense, I just turn a blind eye because I know perfectly well what this is, just ecchi trash where art matters far more than the story. Complaining about the story here is kind of like complaining that porn doesn't have a good enough story, though I do believe the best porn is the stuff that does have proper world building and storyline. Hell, even the timeline makes little sense at most, the world building is so damn bad it's kind of funny. Like how it seems the entire mato thing is kind of new but somehow there are families that has probably dealt with this stuff for at least 2 generations or more, how there seems to be very few people in this "army of super powered women", how juvenile and simplistic everything is, how the humanoid mato seems to be "new". The very idea that some random "peach" can grant powers, how skewed the structure between men and women is said to be DESPITE the supposed fact that a vast majority shouldn't have eaten any peach due to limited availability and that you need to literally apply to do so, how weak mato appears, at least at the start, since there never appears to be any real danger. Everyone's actions and decisions are far separate from how real people would act and honestly I feel a bit dumber for every chapter I read, so while I can read a volume in probably 20-30 minutes max, I don't really want to read more than a few at a time.
I somehow still recommend this as long as the protagonist keeps on being useful, energetic and enjoys his circumstances while not being a wuss about anything. The chapters can be read in a few minutes at most since there's very little text. At the end of the day, this is a shounen action ecchi manga, which is a pretty silly combination, how come the manga made for kids are some of the most filled with erotic stuff? How come such a silly plot is combined with so much depraved garbage?
