Synopsis

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.

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 ...

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 ...

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 ...
