Despite returning victorious from a dangerous struggle, Kanata and his friends have, in a sense, lost a key ally, the amnesiac magus Noir. Having partially recovered her memory, Noir reverted back to her former personality: that of Mystere, who acts in a patronizing manner toward her master Kanata. However, Mystere remembers detecting a signal from Histoire, a mystical city, during her former life as an artificially intelligent magus. Meanwhile, Tokio disappears from Rock Town while hunting down the ghosts of his past; however, shocking revelations await the deeper his search goes. As Kanata, his childhood friend Ellie, and the magus diva Ciel set out for Histoire, a hostile organization named Ideal sends assassins after them. If Kanata wants to stand a chance at accomplishing his dream, he must uncover the unpleasant truth about Ideal—and some of his closest allies.

What is their place in the world now? In the beginning was the Voice, and the word was Him; and all obeyed His word in great awe. But those who dwelt upon the land, through vanity, cunning and greed, attempted to build a multitude of towers whose tops reached unto heaven, and accumulated great wealth on earth. Scattering across the land and laying it to waste, man turned a deaf ear to His Voice. So He gave unto man an opportunity to atone for his misdeeds; and flame and smoke and the roar of a lion descended upon earth; and shattered the many towers to dust....
