Mahou Faeries

As Raiu and Haruaki were walking home from school one day Raiu found a strange orb on the ground. The next day some weird blue-haired girl came looking for it, but she turned out to be an alien monster! Suddenly the orb changed Raiu into a magical fire fairy and drove the alien away. Later Haruaki found another orb and transformed as well. Now they both must fight these alien monsters who want to take Earth's hidden magic for themselves.
