A crafty toy company known as Wiz, or Dark Wiz Company, discovers crystals that contain the faint DNA of monsters called Legendz and turns them into a battle game. After a baseball game, a young boy named Shu receives one of these crystals, called a soul figure, from his father. Legendz quickly becomes popular, drawing more and more children into the game. Wiz’s employees begin tracking Shu, because his special soul figure can revive real Legendz, not just the tiny digital images. Shu must fight to protect his soul figure and claim victory.
