Do I need to watch "Railgun T" first to understand "Index 3" more easily? I currently rewatching the To Aru series with all spin-offs (have only seen the first 2 Index and Railgun seasons years ago). My question is, after watching the first 2 seasons of Index and Railgun and Accelerator, should I watch Railgun T or Index 3 first?
I heard Index 3 is a strong rushed series and really hard to follow if someone doesn't know the novel or the manga. Will Railgun T help with that, or is it not of any help to understand Index 3? Is it, in the first place, hard to understand?
A Certain Scientific Railgun T is unlikely to help you understand A Certain Magical Index III. I've watched the anime for Index, and around half the episodes for Railgun T. Additionally, I've read the manga for A Certain Scientific Railgun, as well as reviewed summaries for the remaining episodes. I strongly suspect that the remaining episodes will closely follow the manga as the first half of the season did. Thus, I can pretty much infer Railgun T isn't going to help. These arcs pretty much tells their own story, and don't have much to do with the story told in Index.
Trying not to spoil anything, but given the contents of episode 68 of Railgun, I'd actually guess that it'll be helpful to watch A Certain Magical Index III first. And watching A Certain Scientific Accelerator before A Certain Scientific Railgun T will be helpful because some characters from there show up in the second half of Railgun T.
