Legend of Heavenly Sphere Shurato (Japanese: 天空戦記 シュラト, Hepburn: Tenkū Senki Shurato; lit. "Shurato of the Heaven Wars", occasionally spelled in the Siddhaṃ script on the logo and related merchandise), is a Japanese media franchise[b] created by Todoroki Mihara.[2] A manga series by Hiroshi Kawamoto was serialized in Shōnen Gahōsha's Shōnen King in 1988, with its nine chapters collected in two tankōbon volumes. It was followed by an anime series by Tatsunoko. The anime television series ran 38 episodes on TV Tokyo from April 6, 1989, to January 18, 1990, and also received a 6-episode OVA follow-up series named Legend of Heavenly Sphere Shurato: Dark Genesis (天空戦記 シュラト 創世への暗闘, Tenkū Senki Shurato: Sōsei e no Antō; lit. "Shurato of the Heaven Wars: The Secret Feud of Creation"), that ran from August 16, 1991, to March 16, 1992. Set in a parallel world called "Tenkūkai", which exists alongside Earth, evil forces known as the Asura Gods threaten to overcome the forces of good, causing the magical leader of this realm to transport warriors from Earth to their world. It's loosely based on Hindu and Buddhist mythology.
