I think it was mentioned earlier, sometime around when his divine powers awakened that since the source of divinity came from the World God himself, he is technically a member of the family. As for World God taking the role of Grandpa, it's because the god himself doesn't like to take on younger appearance and thus can only be considered his grandfather.

Fun fact, the God of Destruction is also the Familia of the World God and it seems GD is planning to take on a retirement package and let Touya take up the mantle instead.
