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.

~Priestess~


*Kurusigawa Himeko*
The Solar Priestess, Himeko is a very shy, innocent 16-year-old girl, and the character that receives most of the anime's attention. At first, Himeko has affections for Sōma Ōgami, who is her childhood friend. She starts off considering Chikane a very close friend, although the two very rarely meet outside of secrecy. Himeko is an amateur photographer of some skill, a hobby she developed thanks to the support she receives from Chikane Himemiya. Himeko is initially a shy and timid girl, uncertain of her own worth and abilities. This is mainly because after the death of her birth parents, she was initially adopted by abusive relatives before being moved to other relatives. At school, Himeko seems to have only one friend (except Souma and Chikane), her dorm roommate Makoto.


*Himemiya Chikane*
The Lunar Priestess; in sharp contrast with Himeko, Chikane is a very commanding girl of the same age. She has a very noble and elegant aura, lives in a large mansion with many maids, and is considered to be of the highest standing at their school; she has a considerable fan following of both genders and is the frequent target of love confessions. She is a member of the prestigious kyudo (Japanese archery) club and frequently uses the bow as her weapon of preference during confrontations with the Orochi. Chikane is also exceptionally skilled in the areas of tennis and, more significantly, the piano; she apparently enjoys playing for Himeko, who enjoys listening to her perform. Many at school believe she has a relationship with Sōma, though this is proven to be untrue.

~Orochi~


*Tsubasa*
The First Neck, he is considered to be the leader and the most powerful of the Orochi. Tsubasa is a tall teal-haired bishōnen, as well as a (presumed) sociopathic criminal with a long record, starting with the murder of his abusive father, whom he killed in order to protect his younger brother.


*Sister Miyako*
The Second Neck, she is a purple-haired nun who is the first Orochi to appear and attack, having lost her faith due to living through a terrible war (presumed somewhere in South America due to her tanned skin color which is a common stereotype in manga and anime). Although there is little co-operation among the Orochi, she seems to be the closest thing therein to a second-in-command and the most cool-headed of the lot; she can control Girochi and induce some semblance of cooperation among the three other female Necks.


*Girochi*
The Third Neck, he is one of the first Orochi to attack the Miko. He is a very large man with heavy chains hanging off him, which he uses as weapons. Girochi is said to be Miyako's younger brother.


*Corona*
The Fourth Neck, she is a delusional pop idol whose dismal sales (68th, though Reiko constantly taunts her with "69th") are partly responsible for her becoming one of the Orochi. She is almost manic in her behavior, constantly trying to impress the other Orochi with her showmanship, but her energetic exterior hides a dark past.


*Reiko Ōta*
The Fifth Neck, she is an antisocial mangaka of few words. Reiko continues her "day job" as a member of the Orochi and has in fact done better on the market since joining, though her manga have taken on very dark themes since then. She barely interacts with the other Orochi and is stone-cold in battle, though her level-headedness is more the product of cynicism and numbness than Miyako's.


*Nekoko*
The Sixth Neck, she is a small, squeaky-voiced catgirl (her name is derived from neko, the Japanese word for cat) who is often seen wearing a nurse's outfit and wielding a giant syringe.


*Ogami Soma*
The Seventh Neck, he is the only Orochi who was able to resist becoming completely evil. Sōma is the lone protector of Himeko and Chikane for most of the series and later plays a part in bringing the Orochi down. He has a very high social standing at their school, comparable to Chikane's, and most of their fellow students believe they are dating, though in truth they rarely interact until the Orochi events.

~Others~


*Yukihito*
The temple assistant, his duties are to assist the priest and Miko in readying the weapon that will defeat the Orochi. It is unclear if he is a hired employee, relative of the Ōgami family, or a junior priest-in-training (the last is unlikely, as he is never seen wearing Shinto clerical robes). He is also Sōma's best friend and confidant, though the latter is shown more in the manga than the anime.


*Kazuki Ōgami*
Sōma's older brother and legal guardian, as well as priest of the temple of the Solar and Lunar Miko. His duties are to care for and maintain the legacy of the Miko, as well as to prepare them for battle. Calm and collected, he is especially worried about Sōma and both priestesses. Even still, there are some indicators that imply he's not telling everyone the full extent of what is going on.


*Otoha Kisaragi*
Chikane's personal maid, Otoha is loyal and devoted to Chikane to the point where it is heavily implied that the former may be in love with the latter.


*Makoto Saotome*
Himeko's friend and roommate, "Mako-chan" is an athletic girl, one of the best runners on the Ototachibana track team.
