My House Cat Became the World’s Strongest?!

Tetsuya endures each grueling day at a company that grinds its workers down, and the one bright spot keeping him going is Tama, the beloved housecat waiting for him at home. Nothing prepares him for the shock of returning from work one evening to find that Tama has grown to an absolutely colossal size. For an ordinary office worker like Tetsuya, the world of adventurers has always been firmly out of reach—until his giant feline companion leads him straight to a nearby dungeon and takes down its boss without so much as breaking a sweat. Whether racing across the landscape at breathtaking speed with Tetsuya on his back or radiating powerful buffs through nothing more than his purring, the newly enormous Tama proves to possess abilities every bit as outsized as his new frame. Fortune smiles on the pair again when they rescue a beautiful young streamer, and footage of their effortless dungeon clears explodes across the internet. Their livestreams go viral overnight, and soon the whole world has its eyes fixed on one impossibly adorable, impossibly powerful housecat.
