Introduction
While fulfilling his sworn duty to defend humanity, a young knight meets a tragic end in a battle against demons. In a twist of fate, however, he finds himself in the lowest parts of a dungeon, ironically reincarnated as a Behemoth, an S-class monster of unparalleled strength and one of the very creatures he had once sworn to protect humans from.
Beginning as a juvenile, he deceptively resembles an ordinary orange cat. Despite his seemingly overpowered ability to absorb the skills of any creature he devours, his escape from the dungeon leaves him gravely wounded. Just in time, Aria, a D-rank adventurer, stumbles upon him, decides to nurse him back to health, and ultimately takes him in as her pet, naming him Tama.
Acknowledging Aria as his master and with his knight's honor from his past life on the line, Tama vows to defend her from danger at all costs—even if it means squandering this second chance at life.

If you're an anime tourist who hates or detests ecchi or harem anime, don't watch this; it's not for you. Leave it to the fans of those genres to revel in!
Joking aside, this anime was made for people like me. It had been a long time since a series left me so invigorated. It's a tall glass of pure distilled degeneracy.
We follow the adventures of an ordinary knight who reincarnates as a cat, seemingly bathed in pure aphrodisiac; because every woman he meets—regardless of species—wants to sleep with him. Ah, the classic harem anime!
The setting and plot are typical of European fantasy anime. If you've seen one, you've seen them all. But, as in most series of this type, the setting isn't the main point; the main point is the premise, and that premise is the stylish cat who is a giant.

Unpretentious Reviews
Beheneko has a semi-decent plot. It resolves satisfactorily enough, and wasn't difficult to watch. But it's also super porny for no reason other than to be super porny, and that's a big detraction to me.
I like the idea of sealed forms that can only be activated when conditions are met. I like the method of acquiring new skills, which require an inspiration to materialize. Apart from that, there really isn't much that happens in the anime. I doubt I'll watch it again.
The OP end ED animation and music were unremarkable. I skipped them after watching them once or twice.
No Wow! or What? moments to report.

This show is very similar to the spider Isekai which I enjoyed. It's also similar to the puppy anime and shares the flaw that the heroine wants to fuck the Mc. Other than that it's actually a great bog standard Isekai that might be better than the spider Isekai, as that devolves into cultivation tropes and the cg gets atrocious. Meanwhile the animation in this is beautiful and you have oodles of fanservice.
For the plot a lot of Isekai has some horrible writing on why they get the gift or why they have to power down or everything but in this it's because of his loyalty, dedication, and fear of isolation and is a very natural point. The actual Isekai simply is, and wastes no time on boring things like Stat allocation, he simply is an OP monster that has to hide to stay with his savior.

This is a passable second monitor popcorn ecchi for when you're stuck at home sick for three days type of anime , and that's exactly how I wound up watching it. I watched this show to get some gainaxing up on the monitor while trapped inside with a cold - and it failed. If you like boobs and especially if you like static drawings of boobs then this is your anime - but if you like awesome animation with ridiculous amounts of jiggle and sway then this is probably not your anime because as cute as the story idea is and as copious as the boobery is the animation in this series is pretty low tier .. in other words this anime about boobs didn't even really animate the boobs , or much else. I feel like I am talking about boobs too much but I did just complete this series and frankly that's pretty…

So, Beheneko is definitely an ecchi show—let’s not pretend it’s not. There’s no shortage of fanservice, and the anime knows exactly what it is. But honestly? There’s a lot more going on here than just boobs and jiggle physics.
At its core, this is a fantasy-adventure series with a fun, chaotic energy, and once you get past the wild premise (yes, the elf-girl wants to f*** the S-ranked monster cat), you’ll find a really entertaining story underneath.
The fights are solid, the characters have personality, and the pacing keeps things moving. The world-building is a bit vague at times—you’re not getting deep lore dumps or intricate political systems—but there’s just enough detail to keep you intrigued. I kept wanting to know more about the past war and this mysterious 'Grand Mage'.

Just so i make it all that much clear, this high score is meant for the material used,not for the studio and the animation.
I am this lenient because ecchi anime seem to be an incredible rarity at this point, actually good and uncensored even more so.That being said the fanservice in this anime is light, way lighter then what you are lead to believe at the very least. And it all happens in the bath really, you don't get any "accidents" with the monsters in the dungeon.Already that settles a certain level of seriousness ,and the fact that there is a time for everything. Honestly the only part of the story that's relatively fresh is the reincarnation as a monster,while that's not good news, the characters presented, at least the main cast as you'd call it, do have their own roles,and aren't…

Ok first things first. If you are looking for high quality anything...it's not this. This is a Guilty Pleasure at it's finest! It is just a goofy good time and that's it. This series knows what it is and leans into it full force. It's a hot mess, but in a good way...or in a neutral way for some. It's basically a Popcorn ecchi.
Having said that as someone who loves both ecchi and fantasy.....it was fine.....and that's how I rated it. Truthfully it's pretty average across the board. I bumped it up to a 6 because I did enjoy watching it the whole way through, even if it was a bit repetative. My biggest issue is the wasted potential. This premise is interesting enough, but nothing was really fleshed out at all. The story felt extremely rushed and very little was explained in the way of chara…

This anime is your typical isekai with ecchi elements—that’s pretty much it. Early on, it wasn’t too bad and was actually somewhat enjoyable. The premise had potential, but as the episodes went on, it became clear that the story wasn’t going to do anything special. The main character starts off decently, but eventually, he just turns into a lazy protagonist who relies on the same overpowered spell over and over again. The fight scenes had the opportunity to be exciting, but instead, they ended up feeling repetitive and uninspired. Whenever a new skill is introduced, it’s almost always just a one-shot move, making battles feel less like actual fights and more like quick, effortless flexes.
The animation looks like something straight out of 2015—not necessarily the worst, but definitely ou…

As an ecchi anime fan, Beheneko caught my eye when it was announced. The promise of charming girls paired with a medieval epic infused with J.R.R. Tolkien-esque flair had me hooked from the start. I pictured a world of grand battles, deep lore, and playful fan service—everything I crave in a series like this.
When 2025 rolled in, Beheneko arrived, and I was ready to dive in. Is it bad? Not quite. Is it good? I wouldn’t say that either. It’s like rooting for a sports team tipped to win the championship, only to see them fizzle out in the playoffs. The potential was there—Aria’s quest, Tama’s mysterious power, a kingdom teetering on ruin—but it never ignited. The narrative stumbled, feeling flat and uninspired. By episode 5, I could’ve walked away without a second thought.
The characters i…

Welcome to the nth entry in the 2020s isekai/fantasy deluge of utterly forgettable slop that has continued to plague the airwaves (or should I say bandwidths) of anime for what has felt like time immemorial. The twist this time is that the main character was a fallen hero who has reincarnated as a cat. But not just any cat - he's an S-rank behemoth, capable of astounding skills and abilities that can beat pretty much any threat or enemy he comes across, which takes away any cinematic tension (I shudder at even applying that phrase in this context) that builds up during the course of the show. This makes him, well, just like any other invincible isekai protagonist, except that his hair (or fur) is brown, rather than black like his brethren of clone brothers from the countless other isekai u…

nahhhhhhh for sure you gotta pass this one, it was jebaited anime.
you might think like i do that the cat is the main spotlight here but its not~~~, its like "you though it was cat but it was me dio!" kind of situation, cat's power progression scenes is basically cut off even though they show it but not much, same with the ecchi scenes not much, i mean i already know the thing where they grab you with "ecchi early, story later" and this one are thoooose ones but the 'story later" is so ordinary so generic that you can already predict what will happen next even their monologue n dialogue sooooo generic asf its like im watching a kids show honestly,
no matter what people will say or the anime itself will say, basically to me cat was just a side character and the elf girl is main character,…

BeheNeko - Even a cat can't escape the "How is this NOT a Hentai" premise in a reincarnation story, Isekai or otherwise.
I'm just going to ask a very simple question: Does anyone remember Inu ni Nattara Suki na Hito ni Hirowareta a.k.a My Life as Inukai-san's Dog? That was a show where through a pseudo-reincarnation stage, the MC suddenly finds himself turned into a dog and then is swarmed with the girl that he had a crush on and fell hard for, and the other girls fall even harder for him. That was 2 years ago in Winter 2023, and yet another Winter season has come, and we get exactly that same premise once again, but this time in a stereotypical sword and sorcery, adventure fantasy comedy from novelist Nozomi Ginyoku, who (I'm going to assume) pioneered this kind of raunchy "it's not Hent…
