The Toaru Project, encompassing A Certain Magical Index and its spin-off A Certain Scientific Railgun, is a Japanese light novel and anime franchise set in Academy City, a metropolis where students develop esper superpowers through advanced training. Its dense mythology and large cast of espers have built a dedicated long-term fanbase. Toaru hentai doujinshi are a recurring fixture in that fandom's parody art.
