A young man awakens in the snowy wilderness with no memory. The boy watching over him informs him that his name is Kuroto, which means the winter that announces the end. Claiming to be a traveling companion, Hanashiro reassures Kuroto and says he will help him regain his memory. More questions arise once they reach the nearest town and are soon confronted by the military. While Kuroto attempts to grasp the quickly developing events around him, snow quietly continues to fall.
