Its a tossle between Galuf or Quina. But to be different (and because ive been plaing ix recently) i will go with quina.

I like her because she is hilarious. Always doing funny things. However she is extremely resilient and does not give up. When cleyra blew up she fought on her own to get back to qu's marsh. When she got abandoned in the outer continent she fought all the way around even getting to treno and lindblum and helping the team along the way (when she scares gilgamesh from eiko in treno) and eventually meets zidanes party in lindblum to take up arms against kuja. She never gives up. And i say thats an important thing. Definatly one a person like me needs to aspire to do.
