Guided by a strange, haunting song, elementary-schooler Sorata Suzuhara from the Heisei Era is warped back in time to 1919, in a high-tech ship called Norn9. This ship, flying above towns resembling that of the Meiji or Taishō period, harbours The Gifted, a group of three girls and eight boys with special abilities. As he tries to find a way to return to his time, he discovers incredible secrets about the world and spacetime itself.
