Ueno-san wa Bukiyou

As the head of her middle school's science club, it's only fitting that Ueno is also a brilliant inventor. With devices that can convert any liquid into drinkable water, deodorize the most foul smells, or even generate dark matter to be used as a means of concealment, it seems like nothing is beyond Ueno's capabilities. However, she doesn't invent these devices for the advancement of mankind. Rather, the one force that motivates her is love, the only phenomenon she can't quite figure out.

Ueno is head over heels for Tanaka, her nonchalant fellow club member. Yet, because she is too nervous to confess her love and he is too oblivious to notice her affection, her love life is completely stagnant. In Ueno's mind, if she could just expose him to perverted situations, then surely he'd get flustered and fall for her, right? Assisted by her stone-faced classmate and dedicated wingwoman Yamashita, Ueno employs her many inventions on Tanaka in a lewd manner in hopes that he may one day understand how she feels.

Ueno-san wa Bukiyou truly stands as a testament to how much you can achieve while having so little.

It is a rather simple anime when compared to other series, we could even go as far call it "primitive" in some aspects, if we really wished to do so; Its artstyle is not the nicest, its quite plain and maybe even somewhat bland. Its animation is not the smoothest, it looks like it was made by amateurs on some episodes. Its runtime is as low as it could get and its plot development is simply not existent; we left the show in the same place we found ... it to begin with.

And yet, I liked it.

You wanna know why? Well, it is rather simple (as the show itself this review is about, lol); For while Ueno-san might be somewhat basic on its premise and contents, it has two major positive aspects who managed to keep me hooked to it to the end and give it such a high score as I ended-up doign in the end. I will list them below.

Firstly, it's no doubt the sort of "experimental" vibes the show has, and I mean it; it truly seems like the kind of project a group of beginners who just graduated from animation school would come with when tasked to do so. Now, if you were to be following my review closely up to this point, you might be confused, didn't I just describe the animation here present as "plain" and "bland" on its introduction parragraph? Well, that is indeed true, but I never specified whatever I tought of that aspect as a positive or a negative, however, didn't I? Truth is, we live in an era were everything has to be perfect: clean, polished, sanitized over the point were any human essence the producers might have left on its product is snuffed out of existence and replaced, instead, by the commercial sameness companies oh so much love these days. Considering it's the tried and tested method they know will generate the most revenue on the market and excempt them from any potential backlash or controversy they might find themselves from doign otherwise.

No, Ueno-san wa Bukiyou is the anthitesis to all of that: Its indie, its experimental, and more importantly still: its personal. It is far from beign one of those mass-produced series we see today and has personality smeared all through it. And, you know what? Should that mean the series looks kinda off in some aspects or doesn't look as good as it could should it be more traditionally animated, then I am willing to take it. Since, for someone like me, at least, it's always better to have a low-quality anime with its own character and personality than a masterfully done one who has no identity at all whatsoever, trying to appeal to everyone in the market and appealing to no-one instead.

The second aspect, is something to be expected considering the nature of this show; this is a comedy anime, after all, and the quality of its jokes are in large part what determines the enjoyment the viewers extract from it at the end of its run, whatsoever. And I'm happy to say, Ueno-san hits the right spot on all the critical points who might have turned my opinion against it should it have done otherwise: It presents ourselves with a very simple albeit entertaining formulaic structure where each episode is divided between two chapters of very similar concepts to one another; Ueno-san, beign the needy tsundere she always has been, utilizes some sort of prodigious machinery that pretty much curbs in half the limit of what should be humanly possible to do (seriously, how has this girl not gotten a government contract yet, or at least moved to a more prestigious institution, lol) but not as a way to furthen humanity's scientific pursuits, no no no, we got none of that stuff, but as an excuse to get physically close to her forever crush: Tanaka. To mixed results, I might add.

Because, despite Ueno's undeniable intelligence, she's terribly shy when it comes to her love interest and can't help herself but to craft the most elaborate of plans in order to perv up to him a bit. From peeping up to her skirt, to eating her own panties, this anime gets really creative when it comes to Ueno-san's desires towards her male counterpart.

Sadly, despite how well crafted her plans are, they never seem to work accounting mostly to out titular protagonist's destructive nervousness when it comes to actually carrying them out, Tanaka's clumsyness to realizing her club president's has feelings for him and is actively making advances on them, or simply, due to to their experimental nature, her machines malfunctioning causing what otherwise would have been an (arguably) well-tought plan into degenerating into what can only be descrived as fanservice gallore with sprinkles of chaos thrown here and there. Random humor is the order of the day and this anime does that pretty alright. Fanservice is also employed extensibly and most of the gags this shows sets-up derive from sexually ankward situations who, while I might not mind too much, and even enjoy, to some extent, I know some aren't as comfortable as I am with that type of comedy, so be aware of what you are getting into before deciding to pick this up or not.

Now that we are speaking about sexually splicit themes, let me give you a fair warning before I go to the more technical aspects of the anime and the closing of the review; You see, Ueno-san wa Bukiyou's humor somethimes gets a bit too creative and maybe a bit too out of line... and when I mean "too creative" and "too out of line" I mean that the author has very clearly a bodily fluid fetish and he doesn't hesitate to include it on his work; All through the episodes of this anime, we see inventions, gags, and even portion of the trama that spin around substances such as sweat and similar. Again, I don't really get too bogged down by this type of humor, I even think it is fun to explore other people's fetished in media (as long as they aren't super gross or straight-up illegal, you know). But I know more than one of you will find that particularly uncomfortable to witness, so I am telling you this beforehand so you don't get yucked out by the contents of this series, you know.

Ueno-san also features a pretty solid music repertoire who I am surprised was this good for an anime like this; the OPs and EDs where all pretty good and the backround music, surprisingly enough, has stuck with me even so many months after I watched it originally. Not a really relevant or important aspect to talk about, but I wanted to mention it none the less, since it struck me in a possitive way and haven't seen anyone talking about it also.

Do you know what I also love? The broken english sentences sprinked here and there through the episodes when something happens, "I am smelly girl" and "I am justice" (when speaking about if girls grow hair in their legs naturally or not) beign the ones that inmediatly come to mind. A very minor aspect of the show that never failed to make me laugh and added a bit more personality to such funny moments, lol.

So, in conclusion, what is Ueno-san wa Bukiyou? A very nice albeit simple anime you watch when you have some spare time to burn and want to turn your brain off for a bit. No complex themes here, no overarching plot to follow, no complicated characters to hyper-analyse and draw conclusions over. Just pure and unadulterated silly horniness that no doubt will get a chucke or two out of you.

Go on, give it a chance, I can personally recommend it.

Mixed Feelings

I have described this anime as a uncomfortable comedy. You will laugh, you will grimace, you will root.

Middle school romance meets mad science and typical anime scenarios. If you really want to cringe hard, watch this. If you want to show your friends how far south anime can go, show them this.

12 episodes split into 2 sections each. With a delightful way of making you question your sanity like you came down with a heavy fever and started tripping on the cough syrup.

Do I recco? Strangely yes. Just for the fact that you will ask so many questions and feel like all ... of them were thrown in a box that said "What questions?".

The dub is good. No one phoned in.

Ueno-san wa Bukiyou was a show that piqued my interest whilst browsing through the seasonals before they began to air. It seemed like it'd be a decently funny slice of life comedy that I might get a few cheap laughs out of. What did we get? A short, unfunny waste of time. I figured since I have yet to a review a show of shorter episode time length, I'll give this a shot. Without further adieu, here's my review on aforementioned show.



To start off we'll begin with the story, there isn't much here due to the nature of Ueno-san but I'll elaborate so you guys ... can get the gist of it. The basic premise is more or less a group of middle school students in a Science club create new experiments . Ueno subjects the other two, Tanaka mainly, to her concoctions in some sort of elaborate ruse to get Tanaka to partake in lewd actions of affection towards Ueno. Meanwhile, Yamashita is mostly a bystander of the others shenanigans. This repeats for the entirety of the 12 episodes, with each episode split up into two separate experiments. It's fairly simple and non-convoluted if that's up your alley, but with it being impeccably formulaic, watching one episode is basically seeing all of them.



Next up is the characters, with there being three main characters. Ueno is uh, a rather perverse character. As I mentioned before, she has a crush on the male MC Tanaka. Her experiments ranged from trying to make Tanaka consuming her urine to him eating her panties (alright Japan). Anytime her crush is finally about to go through with her experiments she chickens out and REEEEEE's in typical tsundere loli fashion. Tanaka himself is either the biggest airhead savant ever created or just so fed up with Ueno's shit that he acts like he's completely unaware of her intentions. I honestly can't pick between the two and I probably don't wanna know. It's not so much of a dynamic of his personality, it's more so of a driving force in the shows "plot". Not really much of you can describe about him other than that it got old quick. Yamashita is long-line character in the deadpan trope. These characters are always hit or miss for me, and it's on the latter end of that spectrum this time around. She gives me hints of Yuki from Haruhi and Mai from Nichijou. More or less there to play along with Ueno's shenanigans, she as well doesn't contribute much of anything.




Lastly, I'll group the art and sound/ost together: Honestly, there isn't much to complain about here, it's incredibly run of the mill in both categories. Nothing really stands out in a good or bad way; it's just there.




Pro's-

Short run time, so even if it's not your cup of tea you can finish it in a couple of hours at most

Falls along of absurdist comedy, which I typically enjoy unfortunately not in this case


Con's-

Jokes are incredibly off-putting

Characters are quite bad

Formulaic nature ruins the longevity of the show


Recommendations: Takagi-san; a more light-hearted sweeter version of this show without the lewd jokes.

Asobi Asobase; A group of middle school girls doing shenanigans in their club-has more mature styled comedy like Ueno-san.



Thanks again, for reading my reviews everyone. I hope this have given you some insight if you want to indulge into this show or not.
