I have a small suspicion about who the "Princess" may be.
The only ones who had any potential to be the Princess--or at least the only ones who revealed that they did--were
Soushi, Tetra, and Excel. Soushi has been eaten, and Excel... essentially admitted to me that she was not royalty (as if there was any doubt).
Though Tetra's only factor is that she was the target of the audience regarding being a "Princess," she is the only one left of these three. And while the audience has rarely been kind or purposely helpful when I encounter them... they tend to be unnervingly correct.
