One month after the Ouroborous, an amalgamation of both authentic and mass-produced Model Ws destined for use by the Mega Man King, falls into the sea following Albert's defeat at the Hunter Ashe, the world is once more lulled into a false peace. However, the world is once more on the road to ruin from one who wants to garner absolute control over humans and reploids alike, and once more two heroes must step forward to stop it, hoping to gain the one true peace that so may before had strived for. One is born of the past, and wishes to repent for transgressions past made in a time of despair. The other is born of the present, bearing a wounded heart that had only just begun to heal, only for the hands of fate tear old scars open once more.
