Slayers Extra (a.k.a. Slayers EX) is a four volume radio drama, set a few months after the first season of the anime. Each volume is a short story adapted from the Slayers Special novels, though Naga is replaced by Gourry, Amelia, and Zelgadiss. The Prologues for each volume of the drama are generally short little vignettes with little connection to the overall plot In addition to the dramas, volumes one through three also come with background music tracks from season one and other bonus songs.
