Despite the recent Akuma attack, the Black Order members remain upbeat as they prepare to relocate to a new stronghold. However, immediately upon his arrival, Allen Walker is summoned by the Central Agency and has his arm forcibly shut by the Order. He is subsequently brought to an unexpected encounter with his master, General Cross Marian, who discloses shocking revelations about the enigmatic 14th Noah. What does a phantom thief event, the entrance of a mystery troop of Exorcists, the murder of a key comrade, and an all-out war against the Noah Family mean for Allen, Yuu Kanda, and the rest of the Order? This is only the beginning of a weird, apparently unrelated chain of events that would lead to something far greater.
