## Characters
### Katsuragi Kuon (葛木 久遠)
A first-year high school, school librarian and apprentice Onmyouji. Outside of class, she's either busy with her librarian duties or assists her father during exorcism commissions. Because of this, she's perpetually turning down invitations to hang out with her classmates. 

She's been trained by her father in the Onmyouji arts of exorcism from a young age. She also consumes a draught of traditional Chinese medicine regularly on her father's orders, ostensibly to regulate her abilities. 

[Spoiler] The offspring of a forced union between Katsuragi Kimihiro's younger sister and a demon fox, Kimihiro freed her from the cult's clutches and raised her as his adoptive daughter. Although she should have been eliminated because of her demonic lineage, Kimihiro could not bring himself to kill his sister's child and decided to raise her as a human. The Onmyouji training and the medicine are meant to prevent her from manifesting her demon powers.

She's trained to use her talismans to summon fire to destroy evil spirits and demons. When her demonic powers awaken and she loses control, she uses lightning spells instead. The medicine she regularly imbibes is meant to shackle her innate demonic powers, not consuming it for two days coupled with repeated sexual intercourse is enough to make her lose control.

### Kizuki Rei (鬼月 零)
She lost her parents at a young age and was shuffled between relatives' homes for a while, but now lives alone. 

She doesn't show her emotions and doesn't talk much, so people often say they can't tell what she's thinking.  

After learning that a demon was involved in her parents' deaths, she has been traveling across the country gathering information to find that demon and seek revenge. 

The wooden sword she carries is a memento from her father, who was a master swordsman, and she never parts with it. 

Her vampire blood is diluted, so it doesn't significantly affect her daily life, but she has a tendency to avoid sun exposure as much as possible. 

Interestingly, she has a sweet tooth.

### Katsuragi Kimihiro (葛木 公弘)
Kuon's father. Descended from a long line of Onmyouji exorcists, he now runs a Shinto shrine as its priest and is a writer by profession. He accepts exorcism requests from multiple parties. He is protective of his daughter Kuon and is initially unwilling to take up the sisters' request for fear of endangering her. 

[Spoiler] Kimihiro and his sister were targeted by the cult before Kuon was born. When the latter was captured and forced to give birth to a half-demon, Kimihiro was able to save the child but not his sister. He couldn't bring himself to kill his sister's child, but her powerful lineage meant he had to watch over her as the adoptive father and prevent her demonic powers from manifesting. 

Although reluctant to take on the Shindou sisters' request for help investigating a spate of demonic-related missing persons cases, he eventually relents but falls for a trap laid by the cult soon afterwards.

In the bad ending, he is killed with his adopted daughter Kuon long past salvation. In the true ending, his petrification spell is dispelled and he returns to his family. He also comes clean regarding the circumstance of Kuon's birth. [/Spoiler]

### Kitakawa Touma (喜多川 冬馬)
Setsuna's classmate and childhood friend. He learnt martial arts together with her and is arguably more skilled than she is, however he lacks the sisters' ability to harm demons. He is privy to the sisters' secret occupation as exorcists and tries to help them anyway he can. He flags up the increasing frequency of demonic possession to Setsuna and is concerned about the trouble it forebodes.

[Spoiler] After Yuuka's disappearance, he worries about the burden on Setsuna as the sole remaining exorcist in their town and eventually volunteers as an apprentice exorcist. The local priest who has watched over the sisters since they were children agrees, as the Church HQ has sent out orders that Setsuna be protected and her stubborn refusal to accept new partners allows him to assign Touma as her bodyguard.

After their first exorcism together, Touma gathers his resolve to assist Setsuna in any way he can, even if he cannot help in the actual battle against the demon. He is surprised at how draining the process is, despite being in decent physical shape himself.

When the demon cult makes its move for Setsuna, Touma is also captured despite the pair's best efforts to escape. He is then used as a bargaining chip to coerce Setsuna into deceiving her fellow classmates to serve as fellow breeding vessels. 

In the bad end, he is executed by the cult when Setsuna openly disobeys orders. In the true end he succeeds in sending out an SOS to the Church HQ. He then prepares a ruse to deceive the cult into letting him out to bring the girls in Setsuna's stead. Eventually he brings reinforcements from the Church and helps rescue the sisters.

Despite seeing what Setsuna went through and being an unwilling accessory to her ordeal, he continues to treat her as before despite his growing romantic feelings for her. [/Spoiler]
