In the third volume of Chi's Sweet Home, Chi has made a new friend. There is another cat in the neighborhood. This cat is the very cat that the building manager considers to be a nuisance and the same one with a reward on his head. The cat's name is Kuro; a giant of a feline. All black and with a bit of an appetite, this cat has been known to not only sneak into people's yards but he has even been bold enough to enter some apartments searching for food.
