Pazu is the protagonist of Castle in the Sky.
Pazu is very active as he helps out in the mines, and is also very friendly, as he serves the miners around him. Pazu's personality strongly changes after he meets Sheeta and saves her multiple times. He becomes very brave and sometimes reckless in saving Sheeta. However, according to Dola, he "...has finally become a man..."
Pazu has brown hair and black or dark brown eyes. He wears a white shirt, orange vest and yellow cap, and is very cute. He is very good at climbing: vines, rock, brick walls, and even smooth surfaces. He usually smiles, and his voice can be normal for a boy, or a little squeaky when he's scared or in a rush.
Pazu is an orphan who lives alone in a small cottage atop a hill. He promised his dead father he would find Laputa and prove him right. Pazu discovers Sheeta slowly floating down from the sky. He takes her home and cares for her until she wakes up. Upon hearing her story, he vows to help her. The two go through a lot, being chased by pirates as well as the army. Eventually, both are caught by the army, but Pazu is set free upon Sheeta's promise to stay with them and help them find Laputa. Upon Pazu's return to his home, he is captured by the pirates that chased them earlier. He teams up with the pirates to help Sheeta escape the army. Once rescued, they continue to work with the pirates to find Laputa, discovering that the pirates are actually good and kind. During their travels, Pazu and Sheeta grow closer.
