Fresh off his defeat of The Spirit Eaters, Daisuke is once again called into action, this time to rescue a fellow Circle agent who has gotten into deep trouble in Cairo.

The agent, Anatoly, was sent to investigate the leader of the Spirit Eaters and from the looks of it, someone doesn't want him digging too deep. And they're perfectly willing to kill to keep their secrets.

Daisuke and Anatoly team up to try and figure out what is going on in Cairo. What they find is a threat to the entire region if not the world.
