Ashitaka (アシタカ Ashitaka) is a 17 year old boy and the last prince of the Emishi tribe. He was cursed when defending his village from the demon boar Nago. After the battle, he is banished and heads West in search of a cure.

History
Ashitaka is the last prince of the Emishi tribe. The Emishi's are a tribe of people who been banished from the west of Japan. One day, his village was attacked by a demon boar and when he was saving his sister Kaya from the monster, the blood worms wrapped themselves around his arm as he tried to defeat it. Later at the Oracle's hut she told him that it was a boar god named Nago who had been shot with a iron ball and therefore turned into a demon boar. Since Ashitaka was cursed by the worms, the Oracle informed him that the poison will seep into his bones and he will die. The Oracle then told him that he needs to go to western Japan in order to find a cure to lift Nago's curse however, in the law of the Emishi tribe, Ashitaka must be banished and to never set foot in the village again because the people would accept that he is "dead".

When he was about to leave, Kaya gave him her crystal dagger to him as a reminder of her when he leaves. Shortly after, he left the village and journeyed to the west.

Personality
He talks little but has a great sense of justice and would do anything to save San and to lift the curse on his arm from spreading and to stop the war between the humans and the forest god's of the forest. He cares very much for San since he loves her and only wants to try to help her.

San
When Ashitaka first saw her, he was fascinated by the strange girl in the woods. San finally admitted that she does love Ashitaka and he means much to her, however she could not forgive the entire human race for destroying the forest and still continues to live part of the forest with her wolf brothers Yama and Moru. Ashitaka promised her that he will visit San in the forest as soon as possible while rebuilding Iron Town. It is unclear if they were involved in a romantic relationship afterwards, but it is evident that they still care very much for each other.

Kaya
Being a resident of Ashitaka's hometown, the two cared for each other. Before he left the village, Kaya snuck out and gave him her crystal dagger so he 'won't forget his lover'. According to Hayao Miyazaki she died of an illness 1 year after Ashitaka's departure.

Moro - It seems that Moro has a deep hatred as much as San does and she told him about how she found San as a baby and told him to leave at sunrise and when they meet again she would kill him, but when Moro was saving her daughter from the bad Lord Okkoto she said that can she save the girl he loves, which was San, and Moro was finally avenged by Ashitaka.

Lady Eboshi - It's unknown but when he met her but she told him that when the forest are cut down and the trees cleared, this land will be the richest land in Japan but after the war between the forest god's of the forest Ashitaka would go back to IronTown and help rebuild it and make it a better town.

Abilities
Bow and Arrow - He is very skilled with the bow and arrow as he could kill samurai warriors on horses from several meters away.

Sword - Though he doesn't use it much, He loves to ride on Yakul and use his sword. It is shown throughout the film that he can defend himself with a sword and throw it with great accuracy.

Demon Strength: More of an unwanted ability; after encountering Nago, Ashitaka's strength grows tenfold.

Climbing: He can climb very well.
