Pyro Blade "Will-o'-the-Wisp"

The beloved sword of Kisaragi, high-ranked shinobi living in Imari Village. Its name comes from the way only its sheath flickered in the darkness, as if it were a will-o'-the-wisp. Though it was considered a top-class weapon, there are many odd rumors floating around about it, including one that says that wounds made by its blade never heal. Kisaragi--who remained a shinobi till the very end--always had this sword at her side.
