The story takes place a little in the future. Guided by one particular song, young elementary-schooler Suzuhara Sorata, from the Heisei Era, is warped through a time skip to an unfamiliar place that looks much like the towns from the Meiji or Taishou period from his textbooks. In this world, he meets three young ladies and nine young men and joins them on a journey aboard the mysterious Norn ship, a giant globe that floats in midair.
Kanba Yoichi, the protagonist, is a high schooler who has been having dreams about Prince Linkenel, who he refers to as his master, since the passing of his mother. However, his dream has always been the same and ends exactly at the same location every time for the past six years. Longing to save his "master," he stumbles across a fortune teller, who gives him a magical coin to "let him see the sequel of the dream he has been having." After trying to place the coin under his pillow, Yoichi finds himself in the magical world and, there, he meets with his master. And thus, the magical story of the two begins.
