I’d wager some innocent soul thought they were being clever by pointing out what makes a disney princess, and then more innocent souls lapped it up to feel like they’re “in the know.”

Kairi is a Disney Princess and that was a centerpiece of the plot in her story, but she does not sing as far as I know. Certainly not in the first game where this lore was established.

(she honestly has barely any lines or presence at all, which sucks)
