Good news for Jujutsu Kaisen fans! The popular anime will be back for season 2 in 2023. The first season ended in March 2021. The longer break is due to the fact that the prequel movie, Jujutsu Kaisen 0, was in the works. It released in Japan in late 2021, but will be releasing in the US on March 18th.
MAPPA, the studio that is animating the last season of Attack on Titan and also animated the first season of Jujutsu Kaisen, will be animating the second season as well.
