Kotoamatsukami

Kotoamatsukami is the ultimate genjutsu granted by Shisui Uchiha's Mangekyō Sharingan. The technique itself allows the user to control the mind of their opponent and is regarded as a genjutsu of the highest class, due to the victim being entirely unaware that they themselves are being manipulated. 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 to reactivate 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 stealing and later implanting Shisui's Sharingan into his own right eye-socket. However, despite the additional chakra 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 inserted it into the eye belonging to one of his crows. This crow was later forcibly stored inside Naruto Uzumaki and manipulated in such a manner, so as to emerge only in response to confronting Itachi's particular Mangekyō Sharingan. Upon such an 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 anticipation that Sasuke would ultimately undergo a transplantion in order to obtain an Eternal Mangekyō Sharingan.

Trivia

 * It also seems that unlike a number of other Sharingan related techniques, it 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 think that there was a connection between this technique and the power that controlled Yagura, the Fourth Mizukage.
