Hmm... How 'bout:

is a Mangekyō technique capable of altering, erasing, or fabricating memories within a target. Each of these three abilities are applied differently, with the ability to create memories inherint in the user's "left Mangekyō" while the ability to erase resides within the "right Mangekyō". To activate either of these abilities the user must hide the eye that is not to be used (Hiding the right eye if your creating a memory and vice versa). As such the ability to alter memories instead of erasing or creating them is only achieved when both eyes are focused on the target.
