Years after the feud for the life of The Earl, Allen is now the leader of The Black Order and is a adult. Each day, more and more Innocence are awakened. After the battle with The Earl (who is indeed still alive), the amount of Innocence that awaken grew and grew, becoming more frequent then ever before. Although, like all powers, not all of these great powers used for the side of the good, and sometimes the Earl is able to slip his words to convince the to just his brigade of Akuma. (Bounty Hunters)
Unfortunately, Akuma have become more power. More human looking and more less than a machine, the numbers for them are growing, as well as they're power. Not only do they now have human attributes, but they can wield dark magic and power more better than ever, even using weapons in combat.
A new age of Exorcists and Akuma have arisen. There is one question that you must ask yourself...?
