The Fandom Post is reporting that the English dub for the remaining episodes of the second season of the Fire Force anime are scheduled to be added to Hulu on March 26, 2021. The English dub for the first half of the season was added to the service in January 2021.
Tatsumi Minakawa is directing this season based on the scripts overseen by Yamato Haishima. Hideyuki Morioka is handling the character designs. David Production is animating the season.
The story of Fire Force is described as:
Terror has paralyzed the clockwork metropolis of Tokyo. Possessed by demons, people have begun to burst into flame, leading to the establishment of a special firefighting team: the Fire Force, ready to roll on a moment’s notice to fight spontaneous combustion anywhere it might break out. The team is about to get a very unique addition: Shinra, a boy who possesses the unique power to run at the speed of a rocket, leaving behind the famous “devil’s footprints” (and destroying his shoes in the process). Can the Fire Force discover the source of this strange phenomenon and put a stop to it? Or will the city burn to ashes first?
