Zou is about the day-to-day life and adventures of a young anthropomorphic zebra, Zou (Bizou), and his family and friends. Most episodes contain Zou's name in the title and usually take place at Zou's house or in his backyard. Zou lives with his mother, father, grandparents, and great-grandmother. Each episode features some simple problem or issue that Zou must deal with, usually with the assistance of his family and friends.

Zou tells the story of a man with a missing leg who moves forward more intensely than an able-bodied man. The amputated leg, a phantom limb that he can still move in his mind, is the pivotal point of this story. At the same time a trace of the war that made him lose most of his family members and forced him to flee his country, at the same time a brake on his exodus that made walking painful and more laborious than any of his fellow travelers, it is also the fulcrum for his integration into a new territory.

Full of good humour and optimism, YaYa and Zouk is about two squirrel kids having fun as they move between the real and imaginary worlds, accompanied by their toys that come alive.

The dark-haired bishounen is Sakon Tachibana, a puppeteer, and the other is Ukon, his favorite puppet and best friend. Sakon is the (only) grandson of Saemon Tachibana, a national treasure of Japan famous for his manipulation of Bunraku puppets. Ukon is a child doll puppet made in the early Meiji era by the famous female dollmaker Unosuke. Together they run into murders and solve them.
