Catman is still revelling in his solitary lifestyle, and wanders the streets passing the time however he sees fit. From becoming inspired by his kung-fu movie hero, to starting up a feud with a local apple salesman, the apathetic and foul-mouthed feline takes each day as it comes, even if it means getting beaten up or losing a possible lover…
Catman is still as unlucky as ever, to the point where even falling from a building leads to him to become an enemy of the cheese-bearing mafia! Though his life is anything but dull due to encounters with flirtatious booze hounds and street gamblers, Catman is content to live the way he wants: moving from one drink-fueled brawl to the next.
The comedy story follows the daily life of a somewhat flippant Pallas's cat or manul named Manul-kun, an orange tabby cat named Chatora-kun, Sukofu-kun, and other cats.
