An ingenious toy manufacturer called Wiz, also referred to in the series as Dark Wiz Company, discovers crystals containing trace DNA of creatures known as Legendz and transforms them into a competitive game.
A boy named Shu receives one of these crystals, dubbed a soul figure, from his father after a baseball match. The Legendz game quickly gains popularity and more children begin to play it in the game's world. Wiz agents begin hunting Shu for his soul figure, because this crystal can resurrect actual Legendz rather than just the miniature digital avatars. Will Shu manage to overcome obstacles, secure victory, and keep this soul figure for himself?
