A cat turned into a cyborg decides the best way to protect his elderly owners is to pretend nothing changed, hiding inside a stuffed toy skin and speaking in complete sentences nobody's supposed to hear. The joke never gets old because it's not really about the disguise, it's about a pet willing to become something unrecognizable to keep two humans safe. 66 episodes of pure heart wrapped in absurdist sci-fi setup, aimed at people who think a robot cat in a plush costume protecting pensioners is exactly as funny as it sounds.
An elderly couple depends on their cat Kuro for companionship and care, but their peaceful life takes a bizarre turn when he vanishes during a romantic outing. A mad scientist transforms him into a cyborg, complete with control circuitry meant to turn him into an obedient weapon. Kuro breaks free from the programming and discovers his new mechanical body comes with unexpected gifts: human speech and enhanced abilities. The catch is that his metallic appearance terrifies everyone around him. Rather than abandon his owners, Kuro devises a simple solution. He wraps himself in a soft toy costume to maintain his cover as an ordinary pet while secretly using his robotic enhancements to protect the couple from everyday dangers. What follows is a peculiar comedy of errors as Kuro balances his dual existence: the devoted family cat who helps with chores and watches over his humans, and the reluctant cyborg navigating a world that would reject him if they knew the truth. This is absurdist humor grounded in genuine affection, where a machine's greatest power turns out to be its capacity for love.
