Memory-Concealing Manipulative Sand Technique

Sasori used this technique to block memories of himself in the minds of his spies so they wouldn't raise suspicions. Sasori can deactivate the jutsu from any location, thus restoring their memory and making the spy loyal to Sasori again, though it is possible that they will not return to being loyal minions. Sasori used this on Yura and Kabuto Yakushi, although Orochimaru was able to release Kabuto from Sasori's control.
