Magic Knight Rayearth
Umi, Hikaru, and Fuu are three schoolgirls out on a field trip to Tokyo Tower... when suddenly a strange voice summons them to Cefiro, a world full of monsters and magic! They have been brought here as the last hope of the Princess Emeraude, who believes they are the Magic Knights, foretold in legend, who will save her realm. But how are a bunch of junior-high-school kids supposed to defeat the might of the handsome and sinister Lord Zagato... with only an exceedingly strange bunny creature named Mokona as their guide?
