Junki Saiga is a normal high school student with a gift in mathematics. His daily routine is disrupted when his family gets news that his father's remains have been discovered- a noted archaeologist and researcher who had gone missing while exploring a site many years before. Among his remains were notes and artifacts that needed to be identified by the family near a notable triangular mountain in Japan known as "Japan's pyramid", a place suspected by some to be man-made.
