Spoiler alert
Now that I've finished NT, decided to do a top 5 NT volumes tweet

(I know I put them in order but it's not as clear cut as that, it's rather ambiguous, these 5 stood out from the rest)

1. NT 4
2. NT 9
3. NT 21
4. NT 6
5. NT 3

6 40


Diving into the abyss known as Toaru Majutsu no Index, still not sure of the reading order yet, this appears to be the first volume of the series, so I'm starting from here for now, appreciate advice from Toaru readers regarding the same
