Nobody asked to be a cat!
 
After dying in a fight against the forces of evil, a knight is shocked to discover that instead of being reborn as a hero of humanity, he starts his new life as a behemoth-one of the most powerful monsters in the world! The only problem is that a baby behemoth looks an awful lot like...an adorable house cat?! Things grow even more confusing when a beautiful elf adventurer rescues him from the brink of death rather than finishing him off. This house-cat-slash-knight's baffling journey is just getting started...

You've got to be kitten me!
 
A proud knight, slain in battle, finds himself alive once more-reincarnated in the body of a fearsome behemoth. As if he wasn't confused enough by this turn of events, apparently behemoth cubs look exactly like adorable kittens?! Even if the rest of the world sees him as soft and cuddly, he has the honor of a noble warrior and the strength of an unstoppable S-ranked monster, both of which will be put to the test as he fights to protect the beautiful elf who has taken him as her pet!
