Sexy Technique

A variant of the Transformation Technique, the Sexy Technique transforms the user into a naked woman, or in a bikini, typically with seductive posture. Naruto uses this technique to distract or win over men, with all successful attempts causing an exaggerated nosebleed by the victim, while Konohamaru uses it to impress Naruto. Typically, the more perverted the victim, the greater their reaction will be.

After Naruto returned to Konohagakure in Part II, he bragged that he has developed the "new-and-improved" Sexy Technique, but was punched into the distance by Sakura before he had the chance to perform it.

Trivia
