DxD: Gorou Hyoudou Reborn

Gorou Hyoudou, the father of Issei Hyoudou is resurrected by unknown means and is sent back to the past. My first novel, so I'm trying to improve. I don't own the cover, if you do and want me to take it down, I will. There are spelling mistakes thanks to Grammarly and autocorrect having a war on my phone
