Meet Twila Spark, Pinke Pier, Raianne Dasher, Flair Shye, Appel Jackson, and Rebecca Rarity. They're not all friends, although they have given each other a smile or wave in the past, until they all end up together walking home from school.
They find a six necklaces, which, they find, grant them powers to turn into magical girls. They have to find out how to use the 'Elements of Harmony' and how to stop all the creatures... er, monsters trying to destroy their town.
