Master Chief of course
use the song you learn from saria inside the lost woods on the goron chief after playing the song the chief goron dances to the music

Talk to Linebeck, then sail away *remember, you can't leave until you go to talk to the goron chief again after gaining the crimsonine*
you either get one from captin linebacks grave, or you solve the third puzzle in the ends of the earth station. to get to the ends of the earth, you take the goron to the ankoui, then when the chief is on duty, go to his place and take the ankoui to the goron village
You cannot upgrade your sword, but you can do a long mini-quest to get the big goron sword. That should not be confused with the goron knife which costs money, but a better not brake-able sword that is better then the master sword, but it makes you use your shield as if you were young link.
It doesnt matter which one you talk to last. Just talk to all. But you got to kill the Yellow ChuChus on the mountain and then the Gongon will talk to you. That was my last.
