Since the collapse of the DARK organization, Jiro has been traveling aimlessly and pondering whether or not he would ever reunite with Mitsuko. During his travels, Jiro encounters a stunning young woman named Rieko who is safeguarding Akira, a child being pursued by the nefarious Professor Gill. Ironically, Akira is the professor's own son, but he also holds the key to the sinister weapon that underpins Gill's plans for global domination.
