Beheneko: The Elf-Girl's Cat Is Secretly an S-Ranked Monster!

A battle-hardened knight dies fighting evil and wakes up in a very different body, reborn as a baby behemoth, one of the most powerful monsters in the world. Growing into that power will take time, and until he does his massive potential is hidden beneath an absurdly cute, catlike form. An elf adventurer, Aria, decides to take him in as a pet, thinking she’s rescued a harmless companion. Their pairing quickly becomes practical and strange, with Aria depending on unexpected strength while the former knight copes with a new identity, new instincts, and the awkward reality of being a fearsome creature that looks like a housecat.

Released in 2025, the series was created by Nozomi Ginyoku, Mitsuki Yano, and Kanichi Kato, and features voice performances from Hinaki Yano, Tasuku Hatanaka, Hitomi Ueda, Tomori Kusunoki, and Yuu Wakui.

As of early 2025 the show has not received major industry awards or nominations. It has shown up in niche festival lineups and fan-voted rankings, leaving open the possibility of future recognition if its audience continues to grow.

Although still new, the series has sparked a lively online response, with fan art, reaction clips, and cosplay centered on the contrast between the behemoth’s terrifying status and its fluffy appearance. Viewers often share clips highlighting its humorous scenes and action set pieces, and conversations on social feeds compare it to other monster-centric and isekai-style works.

Critical and audience reactions are mixed to positive, reflected in a 6.293/10 average from 29 votes. Reviewers tend to praise the show’s lighthearted tone, action choreography, and humor, while noting it leans into familiar genre beats. Recurring themes include identity and agency, the gap between looks and reality, and how relationships change when power and caretaking intersect.
