Approximately fifty years after the events of the original series, Jack has not aged as a side effect of time travel. His sword is lost, he has given up hope of returning to his time, and he is tormented by hallucinations of his deceased parents, his kingdom, and a mysterious armored figure on horseback. Jack, now using futuristic weapons and robotic samurai armor, rescues a mother and her two children from a beetle drone army, and wanders the land on a motorcycle. Scaramouche—a fast-talking musical assassin robot styled after Sammy Davis Jr.—has destroyed a village and killed its people to get Jack’s attention. Jack delays in arriving to the village but defeats Scaramouche. Meanwhile, seven fraternal twin sisters are raised and trained from birth by an Aku-worshiping cult led by an unnamed High Priestess, their mother, to become the “Daughters of Aku”, a team of assassins with the sole purpose of killing Jack for Aku.
