Battle Spirits: Sword Eyes

Fourteen years after the world's largest nation, Atlantia, was devastated by riots, a boy named Tatewaki Tsurugi, who was hidden from the conflict as a child, grows up in the nearby region of Pacifis without knowing his origins. After discovering the Shining Sword, he begins an adventure. A dark force is seeking the 12 Sword Braves, and as they target Tsurugi, a battle droid named Bringer appears to protect him. Under Bringer's guidance, Tsurugi learns to fight using Battle Spirits and joins the other Sword Braves in their struggle against the dark army, wielding his Key Spirit, Shining Dragon.
