Sid Davis is trying to use ancient magic to revive her, as she is foretold to end the world. To this end, he murdered Kyouji Kuzunoha and the protagonist. Throughout the game, there is an ancient civilization book written by Dr. Azuma that is often quoted. This book was most likely discovered by Sid. In it, it say the incident/catastrophe/destruction written in the history of the city of Hirasaka City (the setting of the game) is a lie initiated by the Yamato dynasty long time ago, during the war against Yamato and the country of Qin, which had a shamanistic matriarchy.
