You're welcome.
Anyway, being the damsel in distress that she was during the second game, I'd say that the time Kairi would learn how to properly fight would be after Ultimecia kidnaps her, and then Tifa rescues her, and then she teaches Kairi how to fight hand-to-hand before she trains with a Keyblade. On, and Tifa needs a new outfit too, complete with white angel wings.
