Urban Legend

Urban Legends (都市伝説) are a form of modern folklore consisting of stories that may or may not have been believed by their tellers to be true. As with all folklore and mythology, the designation suggests nothing about the story's veracity, but merely that it is in circulation, exhibits variation over time, and carries some significance that motivates the community in preserving and propagating it.

Urban legends are a unique part of the world of Toaru Majutsu no Index, specifically Academy City. The legends and rumors are quite often important to the plot later on, and in Toaru Kagaku no Railgun is a central in several storylines, having many storylines based on an urban legend.
