A Nun's Game!

I was taken in by the church when i was a toddler, then raised to be a Nun and serve the Biblical God, whom i devote everything to, even my dreams of peace. But alas, I am talentless... that is until a cheeky creature gives me this 'System' that allows me to ignore my lack of talent and finally follow my desires. Fem/MC, Bloodborne Stuff, Future Smut
