In 1525 feudal Japan, five childhood friends—Yoshi, Inoe, Kenuji, Muji, and Haruka—stumbled into a magical cave and changed their destiny forever. Chosen by the Cat Goddess, they were gifted with immortality and the power to shapeshift into felines, sworn to protect the fragile balance between the human and spirit realms.

Now, 500 years later, they have awakened in the neon sprawl of modern Tokyo (2025). To the kind-hearted Hoshi family, they are just a group of adorable, clumsy house cats. But the moment their owners look away, they transform into stylish, super-powered human warriors.

Narrated by the bubbly Haruka, Neko Saga is a chaotic blend of supernatural action and slice-of-life comedy. Whether they are exorcising evil spirits from a convenience store, fighting off gangsters, or plotting to steal pudding from the fridge, these five guardians prove that Tokyo's toughest protectors hide their claws behind a purr.
