Ayatsuru

Princeharris1993}} Ayatsuru is a unique [[Mangekyō Sharingan technique awakened in Yashiro Asannoo's left eye.

It allows the user to control the targets actions with their left eye, control their actions with the right eye, and control their mind with both eyes.

If a target possesses incrediable will, they can fight for control of their thoughts, body and mind. Unlink most Mangekyō Sharingan genjutsu, it can't be dispelled by one simply possessing a Sharingan, Mangekyō Sharingan, or Eternal Mangekyō Sharingan.

After his battle with Ace Korimachi, it's revealed that Yashiro used a sealing technique to seal it, along with Susanoo and Carnage inside his eyes, ensuring that they are usable in his eyes in case they were transplanted by his brother, whom he left his eyes to, as show in his will. It was later confirmed a success by Keiku Uchiha.
