|“Her friend, an archeologist, I think his name was Dr. Yost, he had gone in to map the area. But he never returned.”|
Dr. Yost is an archaeologist and a friend of Misako. He attempted to map out Primeval's Eye, the location of the Oni Mask of Hatred, but never came back, presumably because of an unfortunate encounter with Crabby.
When the Ninja discussed the map they found, they soon see Primeval's Eye. Lloyd mentioned Dr. Yost went to map the location but never returned.
