Six school-aged female protagonists, each representing a different female character type, and each endowed with a magical element that they use to fight the powers of evil. Eeyup! Friendship is Magic definitely sounds like a shoujo manga (Japanese girl comic).
And it looks like one fan managed to create a doujinshi (fan comic) based off the concept. Kawaii desu ne? (Cute, isn't it?)
