In his past life, Romonus Gremory was named Andrew. He was brought over to this new world because of his boss Rahvdall, the god of Insanity. He was tasked with breaking the fate of DxD or Canon because gods like his boss feed on the chaos of broken fate to grow stronger. Romonus is all for it as he gets to enjoy the perks of being in a lewd world like DxD.
