Hyper violence and bloodletting by Risso.
From the publisher:
HIT-GIRL'S IN CANADA. Our adolescent assassin is locked, loaded, and ready to seriously mess up some Canadians. JEFF LEMIRE and EDUARDO RISSO take on MARK MILLAR'S psychotic, 12-year-old Hit-Girl for the next stop in her blood-soaked world tour. No amount of ice, snow, or Mounties will prevent Mindy from slaughtering her latest enemies.
Collects Hit-Girl #5-8.
