Durning a field trip at the Tokyo Tower, three girls from three different schools, are transported to a medieval like land named Cephiro. The girls introduces themselves, Hikaru, Umi and Fuu, who are all in the 8th grade, reguardless how they look. They are greeted by a wizard named Clef. Clef explains that their high ruler, Princess Emeraude was imprisoned by one of her guards name Zagat, high above the skies of Cephiro. He then explains that Princess Emeraude made it clear about the Legendary Magic Knights, who are destined to save their world.

Guided by Clef's words stuck in their head, they reach the Silent Forrest. They are dropped off by the big griffin like bird, and wonders how the hell are they getting into the mansion like place, when it's surrounded by a wall with no doors.

Fuu suggests on knocking. Umi is very skeptical, but when Hikaru starts to knock on the wall, a door opens. They try to call for someone, but no one is greeting them. They have little arguments on not being rude, and decide to enter without permission. They do not know it, but a monster crawling in the ground, manages to get in while they walk in.

The door shuts, and they enter the mansion. They wonder around a bit, until they hear noise coming from a room. It turns out to be a library, and they see mess coming from someone behind the chair. They ask if the person is Presea, but the person turns around. It turns out that the ""person"" is a cute Pikachu/Hello Jitty cross cover called Mokona.
