Shiki meets a boy named Tomoe Enjou, a runaway who claims to be a murderer. Shiki allows Tomoe to use her apartment as his hideout. And from that day onward, their strange cohabitation begins. But then one day, Tomoe sees his mother whom he's sure he's killed. Shiki and Tomoe head for the Enjou residence in the Ogawa Complex where the two see Tomoe's parents alive! There Shiki encounters a mage named Souren Araya and finds that he is the mastermind behind all of the incidents involving her up to then. Shiki finds herself trapped within spirals of paradox. And this is only the beginning of a vicious plot by Souren Araya, the powerful sorcerer and archrival of Touko.
