There is a magical academy that is located on a floating island in the sky. This is about the students of one of the academy's classes, who's only chance not to fail the semester is to win a competition where they must show off their magic skills.

Following the destruction of the magical floating device, the Magic Academy falls to earth, but unfortunately lands on and breaks a demon seal, releasing hundreds of ancient demons into the forest around the academy. The teachers are barely keeping the demons away and are desperately searching for the pieces of the floating device, so to earn more magic stones, all of the students from Amelia's class decide to leave the academy (even though they were told not to) to find the missing pieces.

On the day before the 765 Productions Fan Appreciation Event, each of the idols prepare to head home. However, Chihaya Kisaragi, uneasy about tomorrow's events, decides to have a last minute personal rehearsal. One thing leads to another as Chihaya, Miki and Haruka are dragged from one exciting situation to the next. What is the truck driver's true destination? What is the secret behind the old house? Will the girls make it in time for the event? Watch as Miki, Haruka, Chihaya and the other idols join together for their biggest adventure yet!
