Muzannokoe

The Muzannokoe (声の無残, Literally meaning: Voice of Cruelty), is the newest sword to be used by a member of the Seven Ninja Swordsmen of the Hidden Mist. The sword is unique because it is classified as a "living sword" similar to Samehada. Unlike Samehada, Muzannokoe responds to the wish of the user, acting under their will instead of it's own. It's main functioning is morphing itself to better attack it's target or to protect the user. It's main appearance however is a pure black staff with sharpened ends and a spike jutting from one side that can be used for stabbing, while also having four square-shaped cuts. With a command, Muzannokoe can quickly lengthen itself, racing towards the target to pierce them. The sword itself acts quite erratic when in the presence of another living sword such as Samehada, responding by morphing one of it's ends into six long sharp limbs that can be used to pierce multiple opponents at once.
