Ephemeral

Itachi activates this technique by simply pointing at his target.

When Itachi used this technique on Naruto Uzumaki crows flocked from Itachi and turned into shuriken that bombarded the opponent, then attemptted to put the target to sleep. Naruto then experienced the sensation of their body parts turning into their 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.
