Amos survived his first mission as Mask Wearer, but soon after that, an encounter with a mysterious girl brings his life to an end—and sends him on his way to Braha, the City of the Dead, where souls await judgment. To get there, Amos, now a spirit himself, boards a boat, on which he meets Jerik, a decapitated criminal who must carry his head everywhere. Jerik tells Amos that Braha is overcrowded with spirits; the gods have shut the doors that lead to paradise and to hell. A key is said to unlock the doors—but its whereabouts are unknown. Only someone who dies and comes back to life can find it. Will Amos be that someone? Will his ingenuity and intelligence be enough to restore order in Braha? Or will he unknowingly serve those who are using him for their own gain? Most importantly, even if Amos finds the key, will he ever return to the land of the living?
