To be fair, Sanji dropping from top3 is to be expected. He lost A LOT of votes outside of Japan, where his pervert gag is not well received like it is in Japan.
The more Oda insists on it, the more he loses fanbase outside of Japan, but there it simply stays the same.
And since I believe Oda cares about the Japan rank more than the rest of the world ranks, I think he will just keep things as they are.
Meh.
