One perfect moment: Roberto
Behind every great criminal genius is a tough as nails enforcer, fanatically loyal, murderously tough, and just plain deadly to encounter. Monster gives us Roberto in this role.
And if that's not enough to draw you in: slash!
Context: Richard Braun's counselor, Doctor Reichwein, has been poking around about the detective, in the fallout of the events of the previous post. These sorts of questions are uncomfortable to all involved, so Roberto has been sent to eliminate him, under the guise of being a cheating husband seeking counseling.
As usual, all scans have been taken from Spectrum Nexus, and not the Viz translation (which is well worth picking up). I'll probably do a perfect moment for Runge/Lunge later this afternoon.
Oh, and if you feel sore at me for constantly ending these posts on cliffhangers, this manga probably isn't for you. It probably has the highest cliffhanger-to-chapter ratio that I've ever read.
