A comedic fantasy manga based on the popular light novel series. In this new adventure, a knight finds himself reincarnated as a behemoth, one of the most powerful monsters in the world, and when he meets a beautiful elf girl, he's ready to fight at her side. Problem is, a baby behemoth looks an awful lot like...a housecat?

Yen Press will also launch the original light novel series for I'm a Behemoth, an S-Ranked Monster, but Mistaken for a Cat, I Live as an Elf Girl's Pet under its Yen On literary imprint this summer.
