Chrono Crusade is maybe the closest you’ll get

Chrono Crusade is a Miko x Yokai adventure story except the Miko is a Nun and the Yokai is a “Demon”.

Mikos are known to use archery to defeat Yokai. No wait, its a nun and westerners use guns, right? And they meet all kinds of Yokai… like good yokai, bad yokai, friendly yokai. No wait, western culture doesn’t have Yokai, they call them Demons. So good demons, bad demons, friendly demons…

Nothing wrong with that :-) Switching up the setting is fine but its not especially “Christian” in theme.
