Ephemeral

Itachi activates this technique by simply pointing at his target. When the technique was used on Naruto Uzumaki, crows flocked from Itachi and turned into shuriken that bombarded him, and then attempted to put him to sleep. Naruto then experienced the sensation of his body parts turning into his closest friends who then tortured him psychologically.

Trivia

 * This jutsu is never named in the anime, manga, or manga databooks. It is instead given a name in Naruto Shippūden: Gekitou Ninja Taisen EX. These video game variations only consist of the damage caused by the crow-turned-shuriken.
