Amnesia

Amnesia (健忘, Kenbō), is one of the ultimate jutsus of the Kaihengan. It causes full memory obliteration in the target.

Usage
By activating this jutsu, the user can completely destroy all crucial memories in the target. The only memories left unaffected are ones that are used for functioning (memory of speaking, dressing etc). This technique can also be used on the user them self, to avoid leaking intel.
