Ephemeral

This technique allows the user to put their opponent within a genjutsu, by simply pointing at their 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. When he resisted the sleep command, Naruto then experienced the sensation of his body parts turning into his closest friends who then tortured him psychologically.

Trivia

 * This genjutsu is never named in the anime, manga, or manga databooks. It is instead given a name in Naruto Shippūden: Gekitō Ninja Taisen! EX. These video game variations only consist of the damage caused by the crow-turned-shuriken.
 * In Naruto Shippūden: Ultimate Ninja 4, this technique is called "Genjutsu: Bubbles". This may be an allusion to the impermanence of bubbles and "Ephemeral" literally meaning something akin to "for a moment" or a short while.
