After he is in Tsukuyomi Mode and uses his Ultimate Jutsu to strike his opponent, 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.
