I was reading Imouto Sae Ireba Ii light novel english version and I got to the part of episode 7 of the anime when they are playing the table top RPG. Haruto asks them what powers they want in the anime Miyako says shoot coins really fast and Chihiro says to negate powers. To my suprise in the book it says A certain magical index. Miyako wants Misaka Mikoto's railgun and it says her name. Chihiro asks for Imagine Breaker but no mention of Touma by name. This is after multiple mentions of Haganai, Gundam and Oreimo.
