Kuro wakes up in Dr. Go's lab after being kidnapped and repaired to become a cyborg. However, Kuro manages to break his control chip, and he sets off to return to his owners' home.
02. Nyan-Nyan Army
Kuro and his owners are invited to a contest at a local store. Kuro, however, realizes this as a ruse set up by Dr. Go and his army of robot cats.
03. Hell Highway
Dr. Go creates a chip that allows Mi to penetrate metal objects and transform them at will. Mi goes out of control with this and eventually becomes a mechanically engineered automobile, which Kuro cannot defeat alone.
04. Appearance of the Flying Robot Family!
Dr. Go constructs two robots: Big Sam and Little Sam. He accidentally sets off a self-destruct bomb and is trapped inside. Kuro and Mi work together to try to deactivate the bomb and save the doctor, who, by that time, has already escaped.
05. M's First Love
Mi falls in love with one of the dogs in the neighborhood, but he does not have the courage to speak to her, and he disguises himself as a dog to try to do so. Meanwhile, another of Dr. Go's inventions causes chaos, and endangers the dog.
