Aku sends forth the robotic ninja Shinobi, Warrior of the Dark, to kill the Samurai. Jack responds to the cries of a young boy from a village beset by robot lobsters. Jack defeats them all while Shinobi watches – then the ninja takes the boy to a nearby ruined tower where he strikes from the darkness at Jack as he follows. Jack knows of the ninja’s technique and reveals that he is trained to blend with the light just as Shinobi can blend with the dark. The warriors of light and dark fight from shadow to light and back again – with the sun going down, Jack quickly runs out of concealment and in a last desperate measure reflects the waning light onto Shinobi and destroys him with a well-tossed sword.
