Kannazuki no Miko (yuri).. good one too
Plot:
Kannazuki no Miko is the story of Himeko and Chikane, the reincarnations of the Solar and Lunar Miko, respectively. They are two high school girls going to the prestigious Ototachibana Academy of Mahoroba, Japan. When an ancient evil rises once more, the girls are plunged into destiny as their long-sealed personas awaken to defend the world against the Orochi. When the Orochi awaken, it is the first day of October (the godless month), which just happens to be Himeko and Chikane's birthday. The first Orochi who tries to kill the Miko is Sōma Ōgami, the boy in love with Himeko. 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 in order to combat the threat while Sōma repels the Orochi efforts to kill them.
The manga goes into more detail on the relationship between Himeko and Chikane, though it is not as focused on it as the anime is. In the end, Himeko chooses to be incarcerated forever in the shrine with Chikane.
