Well, perhaps she discovers her miko powers gradually. At first, she is confused about these new abilities.

And along the way, she could form new alliances with characters who are more open - minded about her transformation into a miko.
Well, a fanfiction about Naruto and Female Alucard could be really interesting. It might combine the ninja world of Naruto with the dark and mysterious elements of Alucard.
