So far so good for me, the first DxD fic that I've read that the MC OC have that longinus. So hoping that you don't drop this fic author because I like the concept of it.
My cuz tried it three times but it never felt right. With me I'm actually trying to write up a history as much as the actual story. That's were The SLASH/DOG Comes into play. It's a perfect prequels DxD
