Yu is a young man who has a past he desperately wants to forget. His present is that he is a superhuman top agent for Arcan, an organization dedicated to protecting ancient artifacts to prevent them from falling into the wrong hands. However, he receives several bloody messages, culminating in the suicide of a friend, telling that Noah would be his death. In response, Yu travels to Turkey to visit the Arcan dig at Mount Arrat, where Noah's Ark is supposed to have rested. Along the way there and at the destination, he learns of forces of his past have returned to stop him and sieze control of the Ark, which turns out to be an alien device of ultimate power.
