Frankenstein Attacks Lupin

Overview

There is a gang who is swiping Lupin's intended targets right before his eyes. The Red Ghost gang uses a spirit gun to call forth a person's spirit, thus getting accurate information. To make it work, they need the body of one of that person's descendants. The next target is Goemon. The plan is to recover Frankenstein's soul, which was stolen by the original Goemon. Will the mightiest monster of all walk the earth again? What will happen to Goemon?
