Allen's sealing breaks something in him that doesn't get fixed. The 14th Noah isn't just a mystery, it's a wound the series keeps reopening, and every answer makes it worse. HALLOW moves fast enough that you feel the weight of what's being lost, even if you miss half the setup, because the character moments land with the precision of someone who's been writing these people for over a decade. Yu Kanda's arc alone justifies the entire reboot. The animation finally matches what the manga always promised.

Allen Walker reaches the Black Order's new headquarters, where his fellow members stay cheerful despite a recent Akuma assault. Shortly afterward, the Central Agency calls for him and the Order seals his arm by force. He is then taken to an unexpected reunion with his master, General Cross Marian, who reveals shocking truths about the enigmatic 14th Noah. A chain of odd, seemingly unrelated events follows: a phantom thief strikes, a mysterious band of Exorcists appears, a key comrade dies, and full-scale war breaks out with the Noah Family. For Allen, Yuu Kanda and the rest of the Order, these incidents point toward something much larger. The show is an action adventure with comedic moments, continuing the Black Order's fight against the Millennium Earl and his Akuma.
