Himiko

Himiko was an obscure shaman queen of Yamataikoku in ancient Japan, and was briefly mentioned in Romance of the Three Kingdoms as having contact with the Kingdom of Wei. Despite ruling the land, there were few who saw her and Japanese historical records have no mention of her, and a debate as to whether or not she actually existed rages to this day.

Warriors Orochi
Himiko is a new character introduced in Warriors Orochi 2. She is a young girl who greatly respects Da Ji who in turn seems to look after her much like a big sister (interestingly, they use similar weapons). Also in the Shu story, she is mentioned as being the key to resurrecting Orochi making him into Orochi X.

Kessen
Himiko appears as a young and bratty prophet in Kessen II. She foretold that Cao Cao has Heaven's will and is worthy of the Mandate of Heaven. She is a powerful sorceress for Wei and Zhuge Liang's rival in magic. She is infatuated with Cao Cao and jealous of any other woman who is close to him. Thus, she usually schemes to get rid of the lady closest to him, Diao Chan. In Shu's ending, she is mentioned leaving for a faraway land in the East. In Wei's ending, she stays with Cao Cao.
