My Feud with the Demon Lord

I actually was reborn, but as luck would have it, I was reborn at the same time as my archrival, the Demon Venerable.

I'm in my own body, while he's in someone else's.

He uses someone else's body to disgust me, and I use my own body to disgust him in return.

Right and wrong, grudges, love and hate, all a muddled, chaotic mess. What counts as merit or blame is all down to fate...
