Before I start to break down the details of my review, here's a no-spoiler TL:DR of it - For what it's worth, this hentai is a masterpiece. The way that the characters are built up and how to plot progresses are truly something to admire, even if there's not much of it. The art style is rather average for your spectrum of hentai, but it's a pass from me in the end, not much to comment on that. Overall, I recommend that you watch this hentai not for your sexual arousal - it'll do the opposite, and watch it for the plot instead. You'll find yourself surprised at how well it does its job.
Details (Some Spoilers!):
Story - 10/10
For the tiny four-episode lifespan of this hentai, it truly drags you into the plot to make you develop feelings for the characters. Actually, I say that, but I really only mean Natsuko in particular. The plot takes a really realistic approach to the story, no dumb mc, no bullshit saves, its just a mirror of the dark things that happen in our world translated into a short 4-ep hentai. And what a good job it does of it.
Art - 6/10
The art isn't really anything special compared to your average Kodakawa or Toei anime, but stands out as above average compared to other hentai, but it's enough to make you realise all the gut-wrenching things that are happening in it. Upon watching it, you'll notice this as well, it's nothing bad, but nothing special either. Apart from that, there's nothing to say.
Sound - 8/10
The 8/10 score comes from the voice acting, which was on point. It completely makes you feel immersed with the characters like you're actually watching a non-acted piece of work. The rest of the sound, as in effects are rather average, nothing really special to note, just the voice acting.
Characters - 9/10
The characters fit the story and setting so well and are developed accordingly to the story. Even simple things like crying because Natsuko gets abused really makes you feel sorry for her while you're in your seat gripping tightly to anything around you to hope for the best. Souji is also a great character as he really makes you on edge with the things that he does to our girl, perfectly playing out his role as the villain in the story.
Enjoyment - 1/10
Despite all the sweet things I've said about this hentai, man is it fucked up, everything that happens to Natsuko in this anime is enough for anyone to just bite their lips and hope for it to stop. In terms of it being a hentai, I really cannot recommend this as fap-material, trust me, you'll hurt yourself unless you're into this kind of shit *wink* *wink*. This hentai is literally the reason I cannot be comfortable next to a bowl of oil and a carton of eggs anymore.
Overall - 8/10
Overall, this hentai is very well executed with its plot and story alongside it's character development. The art is rather average with the voice acting being amazing. I also have to make out that it did a number on my mental health after watching this as it is just so messed up. So take all of these into account if you ever plan on watching it.
Reviewer's notes:
I just want to say that all of this is subjective, so keep that in mind if you're reading this and find that you disagree with a lot of things I mention in this review. I also want to point out that I rate anime in my reviews on their story, art, sound, character and enjoyment. I rated this a 1 on my list purely because it is a hentai, and I rate hentai based on what it's supposed to do - arousal or stimulation, something that I does not do for me. If it was an anime instead, I would have given it an 8 just like this review.
