Duality (Highschool DxD x Male Reader) (alt.version of TttE)

This is an alternate Version of my Book "Tied to the Enemy"

What if Rias wasnt going to accept the relationship between Y/n and Raynare?
obviously Y/n wasn't going to abandon his Lover, so he becomes a stray for her sake.
How with that influence the events going forward?
how will things turn out once Y/n receives a weapon of dark origin?
will it corrupt him further? or will he hold onto his sanity for his fallen angel and her friends?

Again, highschool DXD and everything used in this book are owned by their rightful owners. On don't own shit, oy the idea to this book and the fanfic about it
