Saiyuki Offroad is a digression from the Saiyuki manga. Just like all the other manga of the saga, Minekura Kazuya and her assistants who did the art.[1]

There are two parts to the manga. The first one (the Homura one shot) appeared on the early years of Saiyuki in G-Fantasy and has been inserted in some limited edition Volumes of Saiyuki Gaiden, while the second one was presented as a an official doujinshi when Ichijinsha joined the Comiket in 2005. The 2 parts have been joined together in a very special cover and was sold at the event. Later on the unnamed chapter resurface on some limited edition Saiyuki Reload volumes as extra.
