Darkness spreads as a young exorcist, Allen Walker, rises as humanity's last, greatest hope against the malevolent forces determined to crumble civilization. Akuma—cruel spirits born of tragedy and lost souls—lie in wait in every shadow, eager to answer to their leader, the dreaded Millennium Earl. With a cursed eye that sees evil in its purest form and a blessed arm forged to slay soul-devouring demons, Allen stands ready to confront the encroaching evil. Should he fail, Innocence will be lost forever. The war to decide mankind's fate has begun—and the carnage will be endless.
