Driven by their ghosts - both dead and alive - and a desire for truth, their paths converge in the dark, labyrinthine heart of the city streets. After Luki and Noki confirm the existence of another person who carries the same blade as Naoto, the train that Mihai's on is attacked by a group of inhuman shock troops. As he fights against them, their leader is confronted by none other than Bishop.
Meanwhile, back at the church, Heine begins to reveal to Badou and Naoto the terrible history of his "collar" and his childhood below.
