Magic Knight Rayearth 2

The three teenage girls who saved a world at great cost return to Tokyo, a little older and much wiser. They assume they’ll never see the magical, troubling world of Cefiro again… when they find themselves whisked back there by yet another mysterious force. But this Cefiro looks different than the one they left, and Emeraude couldn’t be the one who summoned them this time. What if the tragic climax of their first adventure was only the beginning?
