During his two-and-a-half years of training with Jiraiya, Naruto Uzumaki on one occasion uses the Sexy Technique against Jiraiya; Naruto transforms into a woman wearing revealing clothes and short shorts. After seeing it, Jiraiya encourages Naruto to take a form that is wearing a thong, which he believes will give him inspiration. Confusing a thong for a mawashi, Naruto transforms into a sumo wrestler. Jiraiya is first startled, then disturbed, then angry to see it, having expected another scantily-clad woman. He complains bitterly until Naruto, irritated, uses the form to knock Jiraiya out.
- This technique debuts in "The New Erotic Ninjutsu Completed!!", an omake included with Kai no Sho. The omake is later adapted for Naruto: Shippūden episode 188.
