Okkoto

Okkoto (乙事主 Okkoto-Nushi) is a character from Princess Mononoke. Okkoto has the ability to see the past by sniffing someone's arm, as he did so on Ashitaka's arm to see Nago's death.

In film
Okkoto is an old boar god that took over Nago's place. Lord Okotto was blind and he and his warriors attempted an attack on the humans. After hearing that Nago the Boar God of the forest had become a demon and killed by Ashitakia he didn't kill him but knew right away that he was the one who killed Nago. When asking him how to lift the curse Okotto told Ashitaka to leave the forest or he would kill the Prince himself. Before he left, Moro tried to reason with Boar god by explaining that the humans have weapons that can kill them. However he tells her he and hs boars will not become animals hunted for meat or made to laugh at. All of his warriors died, and he got severely injured. Princess Mononoke or rather San guided him through a forest where human warriors disguised as Lord Okotto's own warriors snuck towards him. They then injected a piece of iron into him and left, effectively turning him into a demon. His life is then taken away by the Forest Spirit.

Trivia

 * According to Ghibli Official, Okkotonushi and Moro were once lovers until 100 years ago.
