The Amnesia Technique is a powerful technique created by Raiga Kayuga. It is quite common among members of Kagegakure's KIBU. The technique allows the user to erase the short-term memory of a person, by blocking the brain signals to that memory. To execute it, the needed hand seals are formed, and then the user's chakra will remove the desired memories of the target by blocking the brain signals in that person. The range of memory lost can vary, from a few minutes to several days, depending on the will of the user.
The technique is quite useful for information gathering purposes, as shown by members of the Special Interrogation and Torture Force. It is used for erasing the memories of an enemy ninja who has been tortured, which is useful if Kage does not want the ninja to report to his village that he was captured and interrogated.
Miyuki Murakami has attained complete mastery over this technique, due to the fact that her Ketsugan can manipulate the neurological impulses in humans. She needs only to make eye contact to erase memories, often performing the technique without hand seals.
