@B214 This story revolves pretty heavily around the actions of the Christian God. The Great War he fought against devils and fallen angels is what resulted in the creation of the evil pieces since during the War the devil's numbers were dwindled down so heavily and numerous prominent houses were destroyed as a result this is what led the Devils into needing the evil pieces to survive. Even the sacred gears play a major role in this story who are only here as a result of God, and the main character possessing one is only because God didn't predict that humans would be transformed into devils. And Trihexa was sealed by God, which is what resulted in Rizevim creating the Khaos Brigade in the first place in order to undo god's past actions. The way I see it, DxD wouldn't even be here if it wasn't for Christian God's actions.
