Dance of the Moonless Sky

is a technique which combines the user's and  prowess. Unlike most genjutsu, which ensnare victims through sight or sound, the illusory effect of this technique is activated when the victim's body or equipped items come into physical contact with the practitioner's sword. Upon contact the victim is effectively blinded, albeit extremely temporarily. Unlike this blindness only lasts for a single second once contact between the two parties is broken. While seemingly insignificant, due to its brief duration, losing a second of sight in a heated close range fight could very well be equal to death. Furthermore, each clash the practitioner makes with opponents will result in the aforementioned momentary blindness, which could quickly crush an opponent's morale.

Since this illusion is only active for an incredibly short window of time, and it coincides perfectly with the clash of the combatants' weapons, this technique is incredibly difficult to identify as a genjutsu. Even individuals with enhanced and  abilities may overlook the brief chakra disturbance found in victims of this technique. Due to the covert nature of this technique's properties, it isn't well known across the shinobi world.
