Out of some of Hayao Miyazaki's most well known Film te always have one main girl and one main boy. Such as:
Princess Mononoke: Ashitaka and San
Spirited Away: Haku and Chihiro
Castle in the Sky: Pazzu and Sheeta
Howl's Moving Castle: Howl and Sophie

I don't know if anyone else has noticed but out of these four guys, Howl is the only selfish one! :)

Ashitaka risks his life to save San and the forest she loves. He freaking gets shot in the chest to get her out of harms way! He's Awesome!
Haku helps Chihiro sneak around, taking her to see her parents who were cursed to be pigs, saving her clothes...
