Phantom, The Vengeful Man

Narutaki meets with a scientist associate whom he helped earlier. Apparently scientists in the field of energy research have been disappearing then reappearing for a few days at a time. Narutaki starts to do some ground work on this mystery until Ling-Ling is attacked while trying to stop a masked man from kidnapping two prominent scientists. The masked man is the Phantom… and he made off with the scientists, but not before Ling-Ling managed to put a tracer on him. Will Narutaki face this foe?
