The battle between good and evil has a new cast of villains - the horrifying Clan of Noah. Summoned to Earth by the Millennium Earl, they are determined to recover the all-powerful Heart of Innocence and destroy all that is good. But young exorcist Allen Walker and his Black Order brethren will stop at nothing to halt the rising tide of darkness and preserve what little light remains in their world. Should his mission end in failure, humanity will lose more than just a hero - its soul will be devoured by demons of old.
