The night before the day of the Holy Virgin. A holy night when it snows gently.
The priest was in a hurry ahead of the annual ritual.
The girl in charge of the ritual could not attend because of the high fever.
After thinking, Father decided to substitute his daughter, Kurumi, and called him to come to church.
However, this day was also the day when ghosts, ghosts, and demons appeared in the world once a year.
The ghosts interfere with the ritual, so they sexually harass the walnuts with their own hands.
Is it possible for Kurumi to attend the ritual with a pure body while maintaining [Pureness (HP)]?
