Anime That Needs A Sequel

Anime series can need a sequel for a wide range of reasons. Sometimes, an anime's story isn't complete, meaning that it needs one more season to provide it with a satisfactory conclusion. Other times, the anime has brought its story to a satisfactory conclusion, but in the process, it revealed a setting still packed full of narrative potential. Whatever the case, there are a lot of anime series out there that need a sequel for one reason or another.
