Togo Keisuke, a high school boy born and raised in modern Japan, is suddenly transported to another world on his way home. Furthermore, the other world he is transported to has already been influenced by many people from the other world (Keisuke’s hometown) who have been visiting since ancient times, and the medieval European worldview has been transformed into a futuristic urban landscape.
It feels romantic, but something is different from what he imagined. Shaking his head, he lives in this unfamiliar world today as well, checking the footprints left by his ancestors beneath his feet.
