Exorcist prodigy Allen Walker is back! Together with his Black Order comrades, they set sail towards Japan in hopes of finally finding General Cross. But before their journey begins, the open waters greet them with a hoard of deadly Akuma! Swept away by the masses, Allen confronts a creature, the likes of which he's never seen before-a fallen one. A dark truth reveals itself, and Allen must make a choice. Pushing his Innocence to the limit, will he save the one who has fallen in the eyes of God, or will he lose everything trying? And when his arm-his most important weapon-is destroyed, will he climb from utter despair to rediscover the power of his Innocence? With the help of the Black Order's Asian Branch and new friends, he'll find out what it truly means to be an Exorcist.
