Did you know the Japanese name for Night Slash is Tsujigiri (つじぎり), or Crossroad Killing, and refers to the way in which some samurai would test new swords in feudal Japan. This was by hiding in wait by a road (typically a crossroads, thus its literal translation) and waiting for an unsuspecting commoner (i.e. lower class, and so with far fewer rights than the samurai class) to pass by. He would then strike to kill, and in this way learn how well his new sword could cut.
