Minamoto no Yorimitsu
During the reign of Emperor Ichijō (r. 986–1011), a large number of missing people were being reported in the capital city of Kyoto, most of the victims being young women. Abe no Seimei, the famous "onmyōdō" diviner of the imperial court, determines that the "oni"-king of Mt. Ōe (later identified as Shuten-dōji) was responsible for the abductions. The Emperor then commanded Minamoto no Raikō (Minamoto no Yorimitsu) and Fujiwara no Hōshō () to exterminate this demon. Raikō had his four lieutenants called the "shitennō" while Hōshō had only the junior secretary ("shōgen") of Dazaifu to assist them. The party left Kyoto in the year 995.
