However, many of the anime have been left with one season. Most of the time, they are dropped on a whim, and they are never picked up by the studios. This leaves the fans in agony as they wait for an official announcement, which never arrives.

Updated November 4, 2022 by Suzail Ahmad: Every year, different anime studios announce what manga they are adapting. These announcements always bring joy to the fans, who have been waiting for their favorite manga to be animated. While the anime industry continues to grow, there is still a shortage of animators to work on the newer projects, and in order for an animation studio to pick up a new series, they have to drop an older one.

This is extremely heartbreaking for the fans of that particular series as they are unable to enjoy more episodes of their favorite anime. There are a few exceptions, but mostly, the anime never returns for another season.
