Okay, so you have an wrongfully accused man chasing a guilty one. You need a cop to chase the innocent one, too, right? Monster
provides us with a rather creepy one named Runge (Lunge in some translations and the anime).
Runge has two defining characteristics. The first, is that he has an odd mnemonic device to store information. Basically, he types the information on the air, and it's stored in the computer in his head. Then simply make the appropriate gestures, and the information is retrieved. This is both very creepy and oddly cool, and the almost robotic nature of those gestures highlights his second defining characteristic: he is one of the most single-minded people in all of fiction. This is the trait we'll be examining in our perfect moment.
