i have to agree with you on that rating. it has a good story and art

[King~]

What is the order to watch it in?

Index > Index II > Railgun > Railgun S ?

or

Index > Railgun > Index 2 > Railgun S ?

or something else lol. Railgun is my friend's favorite show so I want to watch it in the correct order ^^

Well, technically it doesn't actually matter, since Railgun is a side story, and not actually a sequel or prequel. However, the order I recommend would be:

Index > Specials > Index II > Rewatch specials > Railgun > Railgun S

Why (without spoiling anything ^^) rewatch the specials?

for timeframe its railgun > railgun s > index > index 2
