Once upon a time in the future... The world hundred years after the great flood. Here, the place like Japan in the age of civil wars(Sengoku era). The age when Samurai existed. The age when people were mired in civil war-chaos. The dark age when bandits, stabbers, desperados were prowling here and there. A girl and her gardian, the werewolf, refuged in the forest, where MITSUME, the spectre lived.
