The first entry in the series called The Twelve Kingdoms: Sea of Shadow was published by Kodansha in Japan in 1992; the last Kodansha volume was released in 2001. In 2012 the series was resumed under the Shinchō Bunko line from Shinchosha. Shinchosha has also begun reprinting the older volumes with new cover and interior art from Akihiro Yamada. The first new publication of the series in six years was released in 2019. The Chinese mythology-influenced books were adapted into an anime television series by Pierrot in 2002. It aired on Japan's NHK from April 2002 to August 2003, and totaled 45 episodes. The novels were licensed in the United States by Tokyopop and the first four volumes were released between March 2007 and November 2010 as part of their Pop Fiction line. Subsequently, the English license reverted to Kodansha. The entire anime series has been released on DVD and Blu-ray in the United States by Media Blasters, which are now out of print. The license was transferred to Discotek Media, who released the complete series on Blu-ray in 2019. Plot Yoko Nakajima, an unhappy high school student, is one day suddenly faced with a strange man who swears allegiance to her. After a battle with demon-like beasts, he then takes her to another world along with two of her classmates. There, her appearance has changed and she can understand the language even though her classmates cannot. But their status as "Kaikyaku" (people who come from Earth) makes them hunted fugitives, so they wander the land of the 12 countries, simply trying to survive and to figure out the reason why they were brought to this world. Setting The Twelve Kingdoms tells several stories from the world of the Twelve Kingdoms, located on a group of several islands in another dimension accessible from our world through portals created from naturally-occurring magic (though the other way around is normally impossible). The portals occur in the ocean waters of Japan and China, and every so often will end up dragging someone from our world from those waters to the kingdoms' islands, and/or on rare occasion, pulling an unborn child from the kingdoms into our world, causing them to be born there. On the islands, magic works and societies similar to those of classical Japan and China
