Many fans were eagerly awaiting the second season of Attack on Titan, which was scheduled to air sometime in 2016. There was even a preview video leaked depicting Hange in a rather aggressive interrogation scene atop the wall. However, those fans will have to wait longer to see the second season as Hajime Isayama and the anime’s director Tetsuro Araki, have decided to postpone the season due to a lack of source material.
Isayama’s Attack on Titan (Shingeki no Kyojin) manga publishes monthly and Isayama wishes for the manga to be at least four story arcs ahead of the anime airs; currently, the manga is only two story arcs ahead. Araki stated that if they were to adapt the source material that is out there now, it would be highly likely that original content or “filler” would be inserted into the show in order to flesh out the remainder of the season and rather than subject fans to that, Isayama made the decision to postpone the anime. Given the fact that it’s almost been two years since the first season aired and we’re only two story arcs ahead, it means we probably won’t see a second season for a very long time.
