## Description
The protagonist, Shindou Setsuna, is a female student attending school. She spends time after classes and free days doing holy sister activities with her sister Yuuka. Yet these girls are not just ordinary holy sisters; they have another side. This side is the exorcist one—they cleanse demons that possess people under the cover of night.

Lately, demons have been appearing more often, so the protagonist thought that it was a bad omen. And just then, her sister, Yuuka, was taken prisoner by someone and vanished without a trace. Setsuna searches for her traces with her childhood friend Kitakawa Touma and the holy father, to whom she is so indebted.

Furthermore, the one who kidnapped Yuuka went even for Setsuna. And this was an introduction to the endless hell of debauchery...

## Characters
### Shindou Setsuna (神堂 刹那)
An ordinary high-school student by day, by night she is an exorcist who partners her older sister to resolve exorcism commissions assigned by the Church. She underwent martial arts training together with her childhood friend Touma. During exorcisms, her sister suppresses the demon using a combination of relics and innate spiritual ability so that Setsuna can attack the exposed demon with melee attacks enhanced by innate spiritual power.

[Spoiler] She and her sister were unexpected births in the demonic cult which had abducted their mother for use as a breeding vessel. The church managed to smuggle them out and train them as exorcists, so the cult and their leader opted to bide their time until the girls were ready to resume the role their mother had originally assumed. 

Because of the way the "vessels" are impregnated, it is very possible Setsuna and Yuuka are half-sisters. They do not look alike and have very different physical attributes.

If Setsuna loses hope after the school gang bang scene, she is taken back to the demon cult and eventually gives birth to the next generation of breeding vessles. If she vows to keep going, Touma eventually succeeds in rescuing them with help from the Church. Despite everything she and her sister went through, they vow to continue their work as exorcists.

### 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]

### Shindou Yuuka (神堂 悠果)
Setsuna's older sister and her surrogate mother. She works full-time as a nun in the local church while Setsuna goes to the academy for classes in the day. Before Setsuna partnered Yuuka on exorcisms, Yuuka would work alone or with other exorcists dispatched by the church. She has considerably more experience with exorcisms than Setsuna and has experienced her fair share of failures as well.

[Spoiler] Yuuka was much older than the other children in the orphanage so she acted like a big sister to everyone. Because of this, Setsuna was jealous she never got enough attention from Yuuka when they were growing up. 

She is deceived and abducted by the demon cult when she answers the exorcism commission set up by the cult. After raping and impregnating her, the cult forces her to birth demons. Because of her mother's bloodline, her pregnancy lasts for a matter of weeks and the demons she births mature at an accelerated rate. Throughout her ordeal, she never loses hope despite her submissive demeanour. 

Because she was confined for longer and was not in the same physical condition as Setsuna, she is hospitalised as a result of her exertions. In the bad end, both she and Setsuna become full-time birthing vessels for the demon cult. [/Spoiler]
