Himushi

Himushi (ヒムシ, Himushi) is a mercenary ninja and the leader of the Nokizaru Group.

Himushi and the Nokizaru were hired by the Sugi Village to hunt out the Fourth Raikage and his men after they stole a scroll detailing their employer's hidden techniques. While on their tail, the Nokizaru unleashed a blinding light which dispersed microscopic Exploding Insects which the Kumogakure shinobi inhaled. After killing Nigai with this method, A escaped with his ill subordinate.
Tracking them down, Himushi spied on A and Tsunade and prepared a plan to retrieve the scroll by unleashing more exploding insects and offering the cure in return for it. The result of this plan is unknown as Himushi and his team fled when backup from Kumo arrived.
