Intro
11th century, Medieval Europe.
An era when nations were still young and the world was vastly different from today. Set against lush forests, vast grasslands, old castles, and small villages, the young personifications of nations spend their days in lively commotion.
Francis, who calls himself the "Big Brother of the World," and Arthur, who can't be honest with his feelings, do nothing but bicker whenever they meet. Yet, they share an inseparable bond and can't leave each other alone.
Joined by the reliable eldest brother Scotland, the dragon-loving and caring Wales, and the meddlesome but kind Northern Ireland, they grow little by little through laughter, fights, and adventures.
This is a story depicting the daily lives of young nations that no one knows yet.
