Katashi Uchiha had created this technique to keep his and Yuuka Uchiha's identities as Uchiha's a secret. This is a technique that is simply followed up by all of his Genjutsu's that use his Sharingan as a usage.
The user will use this technique when they have trapped their opponent in a Genjutsu. It erases their memory of ever even seeing the user of this technique and their partners. When the victim is under another Genjutsu the user will look upon their mind and rid of every memory of them and their partners. When the user uses this technique, the Genjutsu that the victim had been placed under them will also be erased from their memory as soon as it ends, however, the damage dealt to the victim will stay with them.
The victim will also have nightmares of the Genjutsu they where palced under before this Genjutsu took place. Meaning that the already placed brain trauma will come back to them every time they sleep for about a week or two, depending on the users skill level. If the nightmares last long enough, the victim will go insane just not from the nightmares but from the lack of sleep they will experience will add on top of the brain trauma.
