Red River (天は赤い河のほとり Sora wa Akai Kawa no Hotori: Anatolia Story?, "Heaven by the Red River"), is a shōjo manga series made by Chie Shinohara. It is published in Japan by Shogakukan, and it is published English by Viz Communications. The series originally ran in Shogakukan's shōjo manga magazine Shōjo Comic. The English releases are currently up to volume 18 of 28.
Red River is about a fifteen-year old Japanese girl named Yuri Suzuki, who is magically transported to Hattusa, the capital of the Hittite Empire in Anatolia, the heart of ancient Turkey. She was summoned by Queen Nakia who means to use Yuri as a human sacrifice. Yuri's blood is the key element needed in placing a curse upon the princes of the land so that they will perish, leaving Nakia's son as the sole heir to the throne.
The story takes place during the reign of King Suppiluliuma I, at a time when the Hittite Empire was near its peak of power, rivaled only by Egypt, which was then ruled by the young Pharaoh Tutankhamen. Many of the people and events in the story are drawn from actual history, from Princes Kail Mursili, Sari Arnuwanda, and Zannanza, to battles with the neighboring Mitanni kingdom around the town of Kizzuwatna.
Both the Japanese and English names are in direct reference to the Halys River, which is colored red in the wet season due to sediment carried by the water's flow, but may also be an allegory for blood or womanhood, both of which are key threads in the story.
