Tossed into an unfriendly Realm, sealed by a Phoenix and carrying the burden of all Realms in the form of the Retained of Chaos. Roi Noire recently turned Nightmare is thrust into a dangerous position, one that threatens to erase Excelsion on the first wrong move. With him in the center of the action, it is going to be his greatest challenge yet. (It is recommended to read the previous Book 0 : Prologue.)

A sequel to God Eater: Infinity Paradise, this story runs months after the collapse of Aegis Island, shortly after the Corrosive Hannibal was defeated and ex-Captain Lindow Amamiya was rescued. Soma still lives in the grief and guilt of losing so much in a single day, but at times of despair, an angel is always meant to appear.

For a long time, humanity was the ruler of the planet, but in 2050 the Gods came... The Aragami. What humanity took thousands of years to build, was lost in a mere year. Man took it's final stand against the seemingly unstoppable monsters, but it's only a matter of time until even that crumbles. After 20 years, there is hope on the horizon, but even that is just a fragile mirage. Among the chaos, one Devil is moving in the shadows or the open when needed. Offering the Devil's Deal to all that need it and taking anything in return that furthers her goal, using any means necessary.
