Are the "A Certain Magical Index" seasons connected?


Can you watch _A Certain Magical Index_ season 3 without watching the other
seasons first? Do you have to watch them in order? Are all the _Index_ seasons
connected or is season 3 a new story?




The seasons of the anime adapt the light novel series which tells a single,
continuous story following the same set of characters across many volumes. As
such it's not recommended that you start with season 3 of the anime, since it
assumes you already know who the main characters are and what major events
already transpired in the previous story arcs.

Starting with season 1 is generally recommended for any sci-fi/fantasy series
with a long, complicated narrative like Index. Missing even one episode can
often mean missing crucial information that helps piece together character
motivations and plot developments.
