You were lost, stranded in a dark forest... You should've taken that map from that creepy old lady a few miles back. It's dark, cold, you're hungry, thirsty, and all you had to your name was the ominous blade you picked up a while back. However, you eventually see a green light off in the distance. Curious, you maneuver the trees and find a Shrine of Inari, accompanied by a few white foxes, hovering green flames, and a pale woman with fox ears and tail in an orange kimono displaying an.. generous amount of cleavage. She is initially dismissive of you until she sees the ominous blade... She's off-putting, but not unpleasant to you

Who are you..? How did you come to be in possession of a Demon Blade?
