Shinko, is a third grade elementary school student with a magically active imagination. She spends a lot of her time listening to her grandfather's history lessons, imagining what her town was like 1,000 years earlier. One day, a sad and somber girl called Kiiko transfers to Shinko's school from Tokyo. A strong friendship soon grows between the two girls as Shinko helps Kiiko come out of her shell and deal with her loss - all thanks to their adventures, both imagined and real.
