The many kingdoms of Yuguto have coexisted for generations through peace talks at a shared round table, each king believing his territory was the whole world, until the day dark monsters begin pouring out of the borderlands. Aram, a young tactician who can share his mana with allies, and the swordsman Yuri, leader of the Volunteer Army, are pulled into the opening battles of a war the kingdoms are not prepared for. This first film compiles the opening episodes of the Chain Chronicle TV series, which adapts the mobile game of the same name.
