New Sexy Technique

An upgraded version of the original Sexy Technique that Naruto developed during the time-skip, though it's mentioned and not used in the beginning of Part II. In the Naruto Fanbook II, an omake chapter taking place during Naruto's two year training shows him performing the upgraded technique on Jiraiya which is shown to be way more effective than the original. Unlike the original version, the transformed Naruto is wearing a devil bikini attire.
