The famous hero Ousu was the son of Emperor Keiko, who ruled Yamato (the region of Nara, Kyoto, and Osaka) during legendary times. Ousu was sent to quell the rebellion of the Kumaso, a native people in Kyushu. As young and beautiful as he was strong and fierce, the young hero borrowed clothes and disguised himself as a woman. In this disguise, he was able to infiltrate an enemy banquet and kill both of the Kumaso leaders. He was thereafter known as Yamato Takeru no Mikoto, “The Champion of Japan.” Yoshitoshi presents the hero on his way to join the Kumaso women. While his costume is convincing, behind his back his sword blade catches the moonlight, foreshadowing the violence to come.
