Dream Saga
Dream Saga (Japanese: 夢幻伝説 タカマガハラ, Hepburn: Mugen Densetsu Takamagahara) is a shōjo manga by Megumi Tachikawa. From the February 1997 issue to the June 1999 issue, it appeared as a serial in the Japanese manga magazine Nakayoshi. Kodansha compiled the twenty-seven chapters into five bound volumes and published them from October 1997 to September 1999.
It is a fantasy adventure tale about a young girl called Yuuki Wakasa, who one day acquires a magical red stone. The stone allows her to travel to Takamagahara (高天原 "High Plane of Heaven"), the dream world, when she sleeps, and can only return to Nakatsukuni (中ツ国 "middle country"), the real world, when she goes to sleep in the dream.
Yuuki discovers that she must save the sun, Amaterasu, from being trapped and destroyed in Takamagahara, or the light will be lost from both worlds forever.
The manga has been translated and republished in German by Egmont Manga & Anime from November 2002 to May 2003, and English by Tokyopop from August 2004 to August 2005. The series has since gone out of print.
