Well, I finally got around to finishing this... and yep... as expected, AVANTGARDE manages to impress through their failure more than anything else. It hits harder than in their previous game, if only because this one is a pure VN and as such, there's nothing BUT story, and thus the quality of it is all the more apparent. Guess I should say: "the lack of quality"...
Now, the thing is, the VN's art is as high quality as one might expect, given previous releases. Though obviously, mileage will vary. I personally have to take points away for the ugly pubic hair they drew on Mayu, and the fact that they make it even uglier in her NTR content... At least they didn't add in armpit hair too... Also, there's a lot less pissing stuff than the previous 2 releases, and fortunately, no weird shit related humor... Or whatever the hell that was in the previous game.
Unfortunately, much like the previous game, they wanted to have their cake and eat it too, and mixed up a bunch of stuff poorly.
What do I mean by this? Well, each heroine has a vanilla route, a NTR route, and an abrupt bad ending. The problem is that the way the characters behave between the different routes and some of the things that happen in them makes it looks like they tried to cram in several different games, rather than a narrative that branches out due to choices.
One particularly easy to spot example is the MC's dick-size and sexual performance. His dick size varies between certain variants of CGs, where it looks thicker than Mayu's forearm and over half that length in one CG, and then it looks average if not small in another. Then of course in NTR routes it goes as far as being referred too as a micro-penis, even though it's never depicted as such. Of course, the other dude's dick is "so much bigger *ahegao*", but even in the one scene we do get with both their dicks together, the size difference isn't anywhere near as extreme as implied. Go for the vanilla routes and MC can do stuff like fuck a girl literally all day long and has moments where his dick doesn't go soft right after cumming. Enter the NTR routes and of course he becomes a premature ejaculator who's out after one shot and can't figure out how to make a girl feel good even if he had a manual.
It's ridiculous. They wanted the MC to be a stud with the girls when he gets them, and then automatically be a cuck if the NTR dude gets involved.
The girls fall ridiculously fast too, and their personalities are inconsistent between their routes. Not to mention that the routes themselves are overall lazy.
One particularly jarring detail, at least for me is the fact that Mayu, who doesn't seriously care about anyone except the MC, and who is willing to kill Airi right away if MC cheats on her... is somehow not willing or able to arrange for the NTR dude to die right after he rapes her for the 1st time, even though she's not addicted to his dick at that point and can still cum with the MC just fine. Yeah. No. I'm not buying this. At all.
All in all, a very mediocre product. Kagura could have picked up something better to translate than this mediocre mess...
