Produced by TMS Entertainment and 8PAN, and directed by Yoshiharu Ashino, it acts as a sequel to the previous D.Gray-man anime series and follows a young Exorcist named Allen Walker from the Black Order which are in charge of destroying weapons, known as Akuma, using objects known as "Innocence".

The new series is directed by Yoshiharu Ashino and written by Michiko Yokote, Tatsuto Higuchi and Kenichi Yamashita, featuring character designs by Yosuke Kabashima.

Aoyama's work received praise by Hoshino due to the fact he has to perform both sides of the Earl: the free-spirited clown-looking like character and the mourning human self who is determined to recover his brother, Nea.

Aoyama also felt that playing the Earl's human form was difficult due to how different he behaves in that appearance to the point of being one of the hardest character to voice.

[17][18] Since he had not watched the original anime for some time, Alex Osborn of IGN appreciated the brief exposition in the sequel's first episode to remind the audience of the plot.

Although he enjoyed the interaction among the main cast, Osborn was confused by the revelation that Allen would become the 14th Noah and had to watch the scene again in order to understand it.

[20] Anne Laurenroth remarked Kanda's character development in Hallow, particularly his fight against Alma Karma and his return to the Order in the finale.
