Dōjutsu: Powerful Calm

Itachi activates his Mangekyō Sharingan, binding his opponent in an illusion. In this illusion Itachi disappears and a black hole appears in the sky. As it devours all surrounding environment, it becomes larger and larger, slowly gaining the form of Itachi's Mangekyō Sharingan as it devours the target, leaving them unconscious in reality.
