With the reveal that the Nefertari Family is in fact of the D. Clan as well and that Imu clearly didn’t know for sure until Cobra revealed it. It got me thinking, what if the initial D is not in fact a family name but actually a political statement from 1000 years ago?
What if 1000 years ago, people of any and all tribes who identified with Joy Boy’s cause took the initial D. into their names in order to publicly declare their support for him. In this way, D. is not a name but a declaration and a political statement about whose side you’re on.
This would explain why even giants like Jaguar D. Saul can be a D even though all the D’s we had seen up to that point were human.
And this would also explain why Imu didn’t know that Lily was a D. It’s possible she was not a known public supporter of Joy Boy and so she never publicly added the D to her name. If the D was actually a family name that would be a fact known to Imu before inviting her to found the World Government. The Nefertari are a well known family with assumedly a long standing history that predates the Void Century. If D was just a regular part of their name, Imu would have known about it.
And it’s likely Oda is hinting at this notion that anyone can be a D. Since at the same time of Cobra’s reveal we get a flashback from Sabo where Luffy and Ace invite Sabo to be a D as well.
What do you guys think?
