Shindou Yuuka

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.
