The Universe of Four Gods
Yuuki Miaka had entered a storybook realm, where a country is about to collapse. There, she was recognized as the Suzaku no Miko, the priestess of Suzaku, one of the four gods.
The four gods each represent four countries. Suzaku, Seiryuu, Genbu, and Byakko. Miaka had landed in Konan, the country protected by Suzaku. She and her friend, Hongo Yui, were both pulled into the book at first, and there, they were saved by a strange boy with the Chinese character "demon" on his forehead. After they thanked him though, he and Yui dissapeared, leaving Miaka by herself. At first, Miaka chased after the boy, thinking he had done something to Yui, but she soon found out that wasn't true, when she ran into him again. Unfortunentally, they were both captured and thrown into the dungeon when Miaka accidentally offended the emperor while he was riding through the city.
Soon enough, Miaka met the emperor when she was trying to escape from the dungeon. He recognized her as the Suzaku no Miko, a girl from another world, and the next day, pronounced her the miko in front of the country.
Eventually, both Yui and Miaka end up in the book. Yui was found in Kutou Country, where she was made Seiryuu no Miko by Nakago, a seishi of Seiryuu. He later manipulates Yui into hating Miaka by using the fact that Yui loved Tamahome. Miaka, though, is trying her hardest to get her best friend back, but it was too late. The two girls were on opposite sides, and nothing could stop either as they both race to call their god.
The job of the Suzaku no Miko is to find all of the seven Suzaku seishi so she can call the god Suzaku. When she does, she will receive three wishes. The seven seishi are named by the constellation which has the name of the character on their body. Every seishi has a chracter. The seven constellations in the Suzaku region are:
Tamahome
Hotohori
Nuriko
Chichiri
Tasuki
Mitsukake
Chiriko
The seishi each have their respective character on a part of their body. This character also gives them a special ability, like Nuriko's is super strength, while Chiriko is very smart. Their job is to protect and aide the Suzaku no Miko.
The series, Fushigi Yuugi, consists of 18 manga volumes, by Watase Yuu. There is also an anime for it. There are basically two "sections" for the series. The first section is about gathering the seishi, then calling the god. That goes through manga 1-13. The second part is about finding Taka, the reincarnation of Tamahome, and Miaka and co. trying to help him regain his memory. In the anime, the OVA's are about what manga 13-18 are about.
