Two weeks to wait in the best scenario, or four weeks to worst for finally having this brutal fucker deserving his suffering and death. I just hope that will not waste by Okaya and Muta's surprise appearance for save their buddy and put Maria in a inconvenient situation. Worst scenario with a timeskip a la Juujika no Rokunin.
It remind a similar scenario with another revenge series, Pumpkin Night, when MC fail to kill bully leader and presumed die a first one after having her hold him at his mercy. Just hope will not the case.
