What anime should I watch first in To Aru?

I want to watch it

railgun first i think? then majutsu

Well, for you to understand the plot going on, i'd say you watch either first. To Aru Majutsu no Index and To Aru Kagaku no Railgun are different dimension, so you could say that their plot are not really connected. Just my opinion tho But i'd suggest you watch To Aru Kagaku no Railgun.

I suggest you watch Index first before Railgun. Side story lang kasi ung Railgun (although, railgun's story came out first). Pro watching index first will make you understand the story more :)

Pero actually mas nagustuhan ko ang railgun than index haha

Personally, I recommend Index s1. Then Railgun s1, s2. Don't bother watching anything else cuz Index anime are sh1t anyway. Railgun All Day

Index S1>Railgun S1>Railgun S2>Index S2.

If you can't wait for the S3 try to read some Novels
