Emperor Reborn (In DxD)

"And I saw a beast coming out of the sea. It had ten horns and seven heads, with ten crowns on its horns, and on each head a blasphemous name. The beast I saw resembled a leopard but had feet like those of a bear and a mouth like that of a lion. The dragon gave the beast his power and his throne and great authority. One of the heads of the beast seemed to have had a fatal wound, but the fatal wound had been healed. The whole world was filled with wonder and followed the beast. People worshiped the dragon because he had given authority to the beast, and they also worshiped the beast and asked, 'Who is like the beast? Who can wage war against it?" Revelation 13:1-4 (Since I like yanderes, there will be a lot of yanderes in the story.)
