Kannazuki no Miko

Plot
Himeko Kurusugawa and Chikane Himemiya are two high school girls who attend the prestigious Ototachibana Academy in the fictional Japanese village of Mahoroba. Himeko and Chikane are also the reincarnations of the Solar and Lunar Miko. When their ancient enemy, the eight Orochi (who are the eight heads of Yamata no Orochi from Japanese folklore) rises once more, the girls are plunged into destiny as their long-sealed persona awaken to defend the world from them. When the Orochi awaken, it is the first day of October (called Kannazuki, lit. "the godless month," in the traditional Japanese lunisolar calendar), which just happens to be Himeko and Chikane's birthday. The first Orochi who tries to kill the Miko is Sōma Ōgami, Himeko's childhood friend who is also in love with her. However, after a blinding flash of light brings him to his senses, he rejects his fate and vows to defend Himeko against the other Orochi. The Miko must awaken Ame no Murakumo to combat the threat while Sōma repels the Orochis' efforts to kill them.
