Well I dodnt know what happened but, this the wiki for the DxD series, so is basically us recollecting the info of this story's world, their characters, its media, and such. Fanfiction ain't one of them. But there is a place where u can post your fanfiction of DxD and read others of the same. the place is dxdfanon.wikia.org

Also Azazel's death is only speculation, especially more since in the EX series gave us a hint that Azazel's future might not be so bright.
