Quick quesiton peeps! So I've begun to read the LN for "A Certain agical Index" (haven't watched any of the anime for the "universe") and while I'm only on volume 7, I am wondering when I should start to read the spin off railgun manga. Do I wait until I finish reading the entire old testiment, or is there a good part in the middle of the LNs where I can pick it up. Thanks and no spoilers please :)
