Kuro is merely an ordinary cat whose sole desire is to protect his owners, an elderly couple unable to care for themselves. One day, while on a date with his girlfriend Pooly, a dog, he is abducted by a malicious scientist and transformed into a robot. Kuro somehow removes the chip that controlled him and observes that people are frightened by his new robotic appearance and that he can now speak like a human. He decides to disguise himself using the skin of a stuffed toy and to continue living as a pet.
