It all makes sense now. Sorbet Kingdom had a tyrannical King, and the Revolutionaries overthrew him, and Kuma assumed the position of the New King, and the World Government smeared his name as if he was the tyrant King of Sorbet Kingdom.
The one thing that doesn't make sense, is if Ginny was the Queen, and died someway, and Bonney was her and Kumas daughter, the how does Bonney in her old age form look exactly like the current Queen.
