The first part of the Attack on Titan anime’s finale will be broadcast as a one-hour special on March 3, 2023, as announced by the NHK. The second part is expected sometime this year. According to studio MAPPA, the finale was supposed to air in one piece but due to the amount of work required had to be split.
Attack on Titan is based on a manga series by Hajime Isayama serialized in Bessatsu Shonen Magazine from 2009 to 2021. The manga ended in April of 2021 after 139 chapters, which were compiled into 34 volumes. The final, 34th volume came out in June 2021. The manga received an anime adaptation by WIT Studio in 2013. Season 2 came in 2017, followed by the third season which was split into two cours. The first cour aired in the summer of 2018, while the second one started in April of 2019. Studio MAPPA took over the franchise for the 4th season, which was titled Attack on Titan Final Season. It started airing in December of 2020 and had a total of 16 episodes. After it finished airing in March of 2021, Part 2 was announced. Attack on Titan Final Season Part 2 started in January of last year, with episode 76.
