Question for people who think Gear 5 was a retcon:
We know the opening arc for One Piece is named "Romance Dawn." Luffy has now been revealed as "Sun God Nika". Dawn = sun here.
If the Will of D is revealed to be the Will of Dawn, would you be willing to admit that Oda always planned on the Nika Fruits' existence, since this would prove that Luffy literally has the Will of Sun/the Dawn itself?
Or will you do this?
