The Attack on Titan Final Season started this year but it's looking like it will not end this year at all. Funimation officially announced on their site that "Attack on Titan: The Final Season Episode 76 will air on NHK in Japan. No additional details were revealed, but stay tuned for updates ahead of the series' winter 2022 return."
Let's try to stay positive here as we know that MAPPA is trying their hardest to get AOT anime just right. Rather a break than them completely trashing this beautiful masterpiece.
