As a Monster Musume fan I honestly just wish the manga would end already
This may sound a bit embarassing, but Monster Musume was one of the very first anime I watched when I was young, I really enjoyed it and to this day I still believe the anime is one of the best Ecchis out there, and not just for the "spicy" content.
I really think the show is funny to this day, and I like how it behaves like a standard harem anime, where the focus is in the relationships between the girls and the main character, it's an Ecchi anime yes, but also has incredibly wholesome moments between the cast that leave you caring for the girls more than you would expect.
After finishing the anime at the time I immediately searched up the manga and I have been reading it since, the thing is, I just can't stand the manga anymore.
For a good time the manga kept following the same standard the anime had, giving cute moments to Darling and the girls, developing the cast, giving focus to the girls who didn't get a lot, etc.
But after a while the structure of the manga started to change, it started with an arc where Darling and the girls get tasked with helping capture three fugitive monster girls and then... that just became the whole manga.
Every arc Smith or some other character comes up to Darling and says "Hey, I have a quest for you!" then the main character needs to find and help/stop some new monster girl with her problems, that always involve something sexual happening between them.
The focus of the manga shifted from romance to random pseudo-cuck sexual escapades between Darling and whatever new species of monster girl the author came up with, or not even that, sometimes the focus just shifts to multi-page illustrations between some background character engaging in sexual activity with a monster girl. The main girls were there when this trend started but nowadays they have become secondary characters in their own manga, sometimes not showing up for entire arcs.
As you can guess from what I have already said the author even discarded the main plot driver of the manga: Darling having to choose one of the girls to marry hasn't been mentioned in like 60 chapters, and the ban in relationships between monster girls and humans got lifted off-screen or something, because now every single background character is always fucking a monster girl every chapter. You could straight up change the title of the manga from "My Everyday Life with Monster Girls" to "Monthly Sexual Misadventures with Random Monster Girls"
And I haven't even mentioned the WORSE part, 2/3 of these misadventures involve LACTATION for some reason, which is a kink I have nothing against but when the "author's not at all disguised fetish" becomes the whole manga of course I'm going to take a problem with it.
I just wish the manga would end, because then even if it's an ass open ending I would stop feeling obligated to keep reading these random anthology stories wearing the corpse of what used to be one of my favorite manga...
