Sexy Technique

The Sexy Technique is simply a Transformation Technique used to transform the user into a beautiful, nude woman (or a woman in a bathing suit, as seen in episode 177 and the Naruto video games). Naruto uses it to distract or win over men, sometimes leading to an exaggerated nosebleed by the victim. It has proven effective against the likes of the Third Hokage, Jiraiya, Ebisu, and Iruka Umino. The only male characters that have been shown not to be affected by this technique or its derived jutsu are Sai, Kakashi and Killer Bee.

Since his return in Part II, Naruto has bragged that he has a new-and-improved upgrade for this technique, but he was punched by Sakura into the distance. In the omake chapter in the second Naruto Fanbook, Naruto performs the upgrade in front of Jiraiya taking place during the time-skip.
