Kotoamatsukami

Kotoamatsukami is the ultimate genjutsu granted by Shisui Uchiha's Mangekyō Sharingan. The technique itself allows the user to enter the opponent's mind and manipulate them by giving them false experiences, making it seem as if they were doing things on their own free will. It is regarded as a genjutsu of the highest class, due to the victim being entirely unaware that they are being manipulated. It's so powerful, or subtle, that even another with a Mangekyō Sharingan can be affected. Furthermore, Itachi entrusted one to Naruto believing it could counter even an Eternal Mangekyō Sharingan.

As a testament to its high repute, the capability is strong enough to even negate Kabuto Yakushi's control over the revived Itachi Uchiha, in spite of the former's authority being considered almost absolute. After the technique is used, it requires around a decade before it can be used again, but this period can be drastically reduced through the possession of Hashirama Senju's cells, as observed by Danzō Shimura's use.

Danzō gained access to this dōjutsu by taking and later implanting Shisui's Sharingan into his own right eye-socket while Shisui was still alive. However, despite the additional stamina granted by Hashirama's cells, Danzō asserted that he still couldn't use the ability multiple times in a single day.

Shisui entrusted his remaining Sharingan to Itachi, who implanted it into the eye belonging to one of his crows. This crow was later forcibly stored inside Naruto Uzumaki and rigged in such a manner, so as to emerge only in response to confronting Itachi's Mangekyō Sharingan. Upon activation, the genjutsu would give the order "protect Konoha" to whomever was affected by it. Itachi intended this to be used on his brother, in the eventuality that he turned against the village and assumed that he would have transplanted his eyes in order to obtain an Eternal Mangekyō Sharingan by then. The crow was instead used on Itachi himself, after encountering Naruto during the Fourth Shinobi World War.

Trivia

 * Unlike a number of other Sharingan related techniques, this ability seemingly doesn't require direct eye contact, as Danzō never removed the bandages that hid it from view.
 * The Fifth Mizukage commented that she couldn't help but conclude that there was a connection between this technique and the power that controlled Yagura, the Fourth Mizukage.
 * With Danzō crushing the eye he took from Shisui and Itachi burning the remaining one, this technique became lost forever.
