A very charming story! It's interesting to glimpse a quiet moment between Yoko and Nia, especially at this stage when (on Yoko's side at least)they're in an uneasy friendship that's still half rivalry. Nice characterization on both sides, and I enjoyed your interpretation of the little events that sent Yoko on her path toward teaching and Nia's decision to be a more practical sort of princess. But this raises as many questions as it answers - what *if* she had been able to teach something to Kamina? - and I love that.
