Some anime have small, manageable casts that allow you to get to know all of the characters on an intimate basis. Other shows have casts so large that they could easily populate a city. While some of these shows let most of their characters fade into the background, the best anime with a large cast manage to use side characters to deepen and develop the larger world that the protagonists inhabit.
Most anime with a lot of characters are shonen series like Naruto, My Hero Academia, Dragon Ball Z, and One Piece. Sports anime like The Prince of Tennis also boast enormous casts consisting of the main team, their rivals, and more.
