Corrin is a close ally of Chrom's and when Lucina goes missing she volunteers to help him search for her. She's royalty from an alternate world and although she is rather friendly she has a powerful dragon rage that can consume her when she is angered.

I'm looking for a voice very similar to the one Corrin has officially in the Super Smash Bros series (Reference here, although you'll have to go to the end to hear her speaking actual lines - https://www.youtube.com/watch?v=ljaqfKPR82Y ). The voice doesn't have to be exact, but i'm looking for something somewhat similar.
