Put simply, this off-brand anime is a sub-par adaption of a frankly groundbreaking visual-novel/eroge (there's an actual reason why, if you looked up Euphoria analysis (prior to the HBO show tarnishing the name), there was quite a lot of tumblr fan theorising, and such). The animation quality is poor, there's no uncensored version (despite the original VN being sold uncensored), the story is dumbed down for some reason, and it doesn't actually keep about 80% of the content (in both the joke term, and the actual meaning - there's less sex here, but also less of everything else).
Actually, you know what? Screw it. This hentai adaption is so mediocre, I'm just gonna tell you what you really should know - don't bother with the hentai, unless you want a quick, dirty fap. If you want the legendary - or, should I say, infamous - context of Euphoria, you should - nay, must - play the original game. It has a genuine look at the human condition and it's many, *many* flaws, a commentary on the nature of humanity itself, and an in-depth analysis of mental health and sexuality. Whilst, might I add, also being an extremely sexual hentai game with absolutely perverse content - and, uh, very well made art.
My score for the game is vastly different to my score for the hentai: the VN easily gets 9-9-8-10-7-9. It's let down by a mediocre soundtrack, and the nature of being a porn game; if anything, I'd read a novel adaption of it, maybe make a series based on the premise. It's a shame the MAL review doesn't allow spoilers, because I could spend hours writing and chatting about the story and ideas surrounding this *literal BDSM porn game* - that's how odd, and entertaining, this blackened nugget of a gem is.
TL;dr - bad hentai, read the visual novel if you wish to find Enlightenment. And, remember - suffering on the surface is our sustenance!
