DxD: Devil’s Advocate

When ambitious executive Vincent Hill tries to modernize his company, his old-school boss responds by poisoning him with digitalis from his garden - but death isn't the end, it's a hostile corporate takeover of the supernatural kind. Reborn as Amon, the disappointing third son of a noble demon house, Vincent discovers he's got a built-in AI assistant and magical powers he never asked for - along with a family reputation in desperate need of restructuring. Armed with corporate cunning, demonic magic, and a plan to climb the infernal social ladder, Vincent's about to show Hell's nobility what happens when you give a dead CEO a second chance at building an empire.
