I would refer to this show as 'sex jokes: the anime', but even that title would be too offensive to the idea of a joke. Quantity should never supersede quality. Unfortunately, it appears this show's writers missed the memo. I'll grant that, as a non-Japanese speaker, it seems at the very least that some 'good' jokes that can't be translated went over my head, but at this point, it may not have made a difference.
Story 4/10:
The basic storyline is about as cut-and-dried as any other. Stop me if you've heard this one before. A slice of life high school anime about a male protagonist - the only person with common sense of course - surrounded by a harem of girls (a tsundere, an obnoxiously nice girl, a nerd, an annoyingly high pitched little sister) who are forced together by some sudden and random event but quickly become close friends over the course of the school year. Basically, the vanilla ice cream of anime.
Of course, however, there is the twist! That being that every five seconds, a character makes some unnecessary and unprovoked sex joke.
At first, the jokes are cute. They aren't necessarily belly-achers, but they're relatively amusing. Mostly it's nose exhales, but every now and then you may even let out an under-the-breath chuckle. By episode 2, you're just asking for it all to end.
Here's a little taste of what the jokes may sound like (btw I literally just clicked a random episode and went to a random timestamp because that's how often and pattern-like the jokes are):
*Someone spills tea on other girl's phone
Girl: Oh no... it's okay. This phone is waterproof. That's why it stays fine even if you put it 'inside'.
......
So, like me, you may be wondering: where is the joke? Indeed, 'putting it inside' is certainly a sexual innuendo. Congratulations, the show mentioned something sexual. But... where is the punchline? Where is the clever writing? That's the thing. It doesn't exist. Almost every joke is simply a throwaway line about some sex-related thing.
Art 6/10:
The animators tried their best to build off of what little material they were given. There was nothing particularly outstanding, but the art certainly complimented the jokes as best they could.
Sound 6/10:
Again, nothing particularly good or bad. It felt fitting for the context of the show.
Character 3/10:
The two best characters of the show, Tsuda and Suzu, were the only two not constantly making sex jokes. Who would have guessed. Even then, every character could pretty much be boiled down to one or two personality/physical traits that defined their character throughout the entirety of the run time. Aria, that one girl who constantly talks about masturbation. Suzu, the girl that is very short and very smart. Hata, the girl who is a perv that sells questionable photos of others and inexplicably misrepresents others in the school newspaper. Mitsuba, that judo girl. The predatory female teacher. The list goes on.
Ironically, the best parts of the show came when characters weren't attempting unfunny sex jokes but actually just earnestly and genuinely interacting with each other. Unfortunately, these interactions are far too sparse and infrequent to invoke any emotional impact.
Enjoyment 3/10:
I tallied the number of times I laughed during the show. Four times. That also ended after episode 4.
Overall 4/10:
If you don't understand Japanese, don't even bother. Even if you do, I still wouldn't get my hopes up. This is a show that thinks itself clever but ultimately boils down to the eastern equivalent of 'that's what she said' jokes. Funny. Until it's repeated about 100 times.
