Ephemeral

Itachi activates this technique by simply pointing at his target. Crows flock from Itachi and turn into shuriken that bombard the opponent, then attempts to put the target to sleep. If that fails, they then experience the sensation of their body parts turning into their closest friends.

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.
