Ahrimanes suddenly approaches Usoko in a dream about a new threat that is emerging, and his warning soon proves to be true as a mysterious cult is bringing people's worst fears to life and wreaking havoc wherever they go; from bringing back old foes, to crashing a wedding, and even defacing the Eiffel Tower itself! Usoko and company are joined by two new allies, Midori Suzumiya, the Lich who once held a grudge against Emiko, and Iris Drake, one of Ahrimanes' spawn that was sent to infiltrate Usoko's group. Will Usoko and friends get to the bottom of all the chaos and put a stop to it once and for all? And will Iris continue to carry out her father's bidding, or will she suddenly have a change of heart?
