Supposed to be a God, I was born in the Preta Realm

The world ended with the tenth world war, humanity barely survived and in one of the last secluded areas where people practised Buddhism, a man passed away after overeating. Dorje Norbu, a gluttonous man who roamed around for free food. His passing earned him the nomination to ascend to godhood as the new God of Gluttony.On his way to heaven, his small boat was swept away by a Tsunami in Sea of the Afterlife, throwing him and his spirit guide into the sea and to a entirely new world.Message soon reached him that the Gods had fallen to the demigods and that he was the only one with his divine powers.Armed with an empty plate, a mysterious Vajra and an endless appetite, his mission is simple:Find the fallen gods or watch the universe collapse on itself.
