Koumi-jima Shuu 7 de Umeru Mesu-tachi

Let me start with the review with this, The animation is horrid. It's like playing one of those Doujin eroge made with RPG Maker, the only difference is at least with this one you'll be handsfree to do your business.

Let's talk about the story, It starts with an island filled with people who are so inbred that they hit their genetic limit. What does that even mean? The females can no longer get pregnant with the males on the island and that's where the MC comes in! (literally).

The saving grace of this OVA? the Voice-work, while nothing groundbreaking it's probably enough to at least ... be able to facilitate some "Hand-to-gland combat."

One of the worst abominations of hentai.

Story: 4
The basic idea wouldn't be that bad, but the execution is just laughable. With a decent story, it could be much better, but the narrative doesn't even try to build one; moreover, it just skips scenes and cuts some of them really weirdly sometimes.

Characters: 2
There's no need to talk about anyone specifically, because the story makes even the offscreen characters stupid.

Art: 3
It's easy to think that women are trying to compensate for their brains with their bodies. It would be okay in a hentai, sure, but this kind of deformation is either disturbing or funny in a bad ... way. The censorship is not the worst point here.

Animation: 2
It would be much more entertaining to watch a PowerPoint presentation or just still hentai pictures from one's favorite anime. There are more still images than animation. Sometimes they don't even bother to create new scenes; they just put some characters in different scenes in the same pose and switch the background.

Music and sound: 4
The studio clearly didn't know how to set the volume of the voice actors. The MC sometimes sounds like he's shouting, but he's bad at it anyway.

The animation is so horrible it's like I'm watching a walkthrough of a game. Riana is the only reason I watched this; I was fixated on her, but wow, seeing it made me immediately drop watching this freakshow. Character design is laughably deformed and there's barely movement therefore becoming so lifeless and boring. I saw better fan-made animation on Rule34 and those were sometimes made by one person. While this is like a cheap shot for money, made by someone who looks at it and says:

"Hmm, it looks terrible... Nudity is good enough to sell it for the simp, so I don't care as ... long we're making money, baby!"

I will never going to bother finishing it because I'm so disappointed right now. The animation doesn't even turn me on, it's so distracting I was laughing. I mean, who's in the right mind to take it seriously? I don't even know what is the plot of this nonsense, probably I wasn't paying attention to the story. But I don't care, to me I'm done.

Though Riana is kinda hot enough for me to make fan art of her...
