Spank (voiced by Noriko Tsukase), the main character and regular protagonist, is a dog whose owner went missing on the high seas. While awaiting his return Spank strays at the beach every day. One day he meets Aiko Morimura (voiced by Mari Okamoto), a junior high school student, whose father also went missing on a yacht tour ten years ago. Her mother, a designer of hats, left for Paris, leaving Aiko in the care of her uncle, Mr. Fujinami. Abandoned, Aiko believes that her father is still alive and awaits his return. She's recently lost her pet dog, Papi, a good-bye present from her mother, in a car accident, leaving her totally devastated. In the course of the anime, Spank begins to lighten up her gloomy mood as he is a clumsy, merry, big-hearted dog. Whereas, Spank finds his love in the pet cat of Aiko's classmate. However, later, he finds in love with a blue dog named Fan Fan. At the end of the anime, despite Spank ruining everything, all will be forgiven cheerfully and all will really fall in love.
