Magic Knight Rayearth begins when three junior high school girls hear a voice asking them to save a world called Cephiro. The voice belongs to Princess Emeraude, the Pillar whose will maintains the peace of this magical world where belief is power. But the peace in Cephiro is now threatened as Princess Emeraude is imprisoned and monsters begin to invade the land. With her last bit of strength, the princess summons forth the three girls destined to become the Magic Knights in the hopes of saving her world.

Level 1: The Birth of the Legendary Magic Knights!
Hikaru Shidou, Umi Ryuuzaki, and Fuu Hououji were ordinary middle school girls in Tokyo - until they were summoned to Cephiro, a fantasy world where one's will rules over all. They are told that unless they become "Magic Knights", defeat the evil priest, and rescue the princess, they can't go back to Tokyo! Guided by the old mage Clef, the three embark on their long journey.

Level 2: Presea of the Woods of Silence
The three girls managed to make it to Presea's house in the Forest of Silence, as instructed by Clef, only to find the door unlocked and nobody home! The girls hear a noise in the study, only to discover a cute, fluffy animal! They eventually meet Presea, but then a monster enters the estate - and the girls must fight without Hikaru's magic...

Level 3: Ferio the Handsome, Mysterious Swordsman
While on their way to the spring of Eterna on Presea's orders, the three girls encounter a mysterious man with a large sword. This man, Ferio, tries to strike a deal with them to help get out of the forest. Our group of four soon find a large rock at the center of the forest, and determine it to be the cause of the forest's numerous monsters... but can they destroy it?

Level 4: Alcyone the Vengeful Sorceress
The three girls part with Ferio and go on their way to Eterna. They stumble across a small town, but all the townsfolk fear the girls from another world - even after they defend the town from a monster. now, Alcyone commences her attack and initiates a grudge match, but Hikaru's magic alone is not enough...
