Yann Bibiyan is the main character. He is a six years old boy, with dark messy hair, naughty eyes and casual look. He is cute, but his eyes and smile and outfit imply that he is not a quite and peacful child. In his big pockets little treasures are stuffed in.
His huge imagination confronts the borders of the 'grown-up world'. He is not bad, but sometimes the consequences of his deeds affect the others in a bad way. He never intends any harm and is just looking forward to discover the world and have some fun. He is innocent, curious, but sometimes misunderstood. His lack of experience and empirical knowledge usually leeds to complications and negative reactions, which he resolves by positive attitude and strong will to make up things.
