Mr. Yakamura, Yoko and Koof are three black cats.

Mr. Yakamura is large and cranky.

Yoko is medium and industrious.

Koof is small and lazy.

Mr. Yakamura is the captain of a fishing boat called The Stinky Samurai.

Yoko is the first mate. She puts the fishing nets out and hauls the fish onto the boat.

Koof is small, so they try to keep her out of the way whenever possible.
