Hey ClarencelackClarity, your The Voices story deals with a Psyker in DxD. I'm reading the fic that has this amazing view of the warp in DxD and how gods and supernatural beings came to be and are affected by it. It's a little flowery but pretty good so far. It's call For Terra in Excelsior!, have you read this? If not, it may help you with any trouble you have with merging the different meta-physics.
I already know her final kit, but, no. First because I'll be copy/pasting someone's idea, and secondly because I simply don't write FUTA stuff.
