The use of the pregnant stomach as an 'o' in the "oh my GOD!" made me laugh far more than it should.
Otherwise, this really didn't do it for me, but I'm really curious about the main character. Is she a trans woman who has been a nun the whole time? Is she a trans woman who became a nun because of the demon pregnancy? Is she a man who was told "Well, you are pregnant so you're going to be a nun instead of a monk"? Is this a world where there is no visual distinction between nun, monk, and priest? What's her story? I'm so curious.
