SORA's keys are two keys that controlled SORA. Sartorius was awarded by Prince Ojin upon winning their Duel. Sartorius' good side was eventually able to hand over the keys to Jaden and Aster for safekeeping. But his evil side sent duelists to get them back. Aster Phoenix confronts him about to give up his key to him but doesn't recognize that the present Sartorius is an imposter, posing as his friend. Sartorius' good personality aids Aster, but the Light of Destruction unleashes "Arcana Force EX - The Light Ruler".
