Name: Silent Killing Technique
Origin: Kirigakure
Description: As the name suggests, this technique is simply a soundless method of killing an opponent, usually from behind with a blade. Additionally, because the user moves silently, the attack cannot be anticipated and defended against. These techniques are treated as stealth techniques of equal rank, and therefore are silent and undetectable by sound detection up to the same rank of the technique. The user can still be ‘sensed’ by the other senses unless they do something to hide those as well, (hearing, taste, touch, sight, chakra sense)
Requirements: Be From/Learn From a Kiri-Nin, 2,000 words training
