Histoire
Hiroki Dan, the Chief of the Tokyo Metropolitan Police Department's 1st Investigation Division, is an elite among elites with a brilliant career. But his hidden side is that of a serial killer who dispenses vigilante justice upon sinful villains. This is the second official spin-off of "Trace: Reminiscences of a Forensic Scientist." The devil's enviable record of vengeance, preying upon the wicked, begins again.
