Now, all seven have been found in the same sleepy little Japanese town, and Emissary tasks 14-year-old Mana Sumire and five other pure hearted girls with finding and purifying these items, which have been infected with the demon's evil touch. If someone were to touch even one, the power would transform them into a wicked demon called a Shadow Beast. To help them, he gives them five special stones - these Light Gems allowing them to assume powerful magical girl forms drawing power from and inspired by their ka, the uniqueness of the soul.
