Fate/Demon goddess

I had an idea of putting a previously dropped character and putting into the fate universe, so I binged the anime to know the character and plot, this is what boredom will do to a man sadness indeed

and also there are already a bunch of Fate FF already so don't expect this to be unique out of the other FF
