New Sexy Technique

In an omake included with the second Naruto fanbook, and later animated and shown after the credits of Naruto: Shippūden episode 188, Jiraiya tries to convince Naruto to make his Sexy Technique even sexier in order to give him some writing inspiration. Naruto shows his progress by turning into the usual form he takes when performing the Sexy Technique, but adds to it by wearing a devil-themed outfit. Excited by this development, Jiraiya suggests Naruto wear a thong as part of his transformation. Confusing a thong for a mawashi, Naruto transforms into a sumo wrestler. When Jiraiya becomes angry with him, he uses the form to knock Jiraiya out. Naruto references this technique when he returns to Konoha after his training, resulting in him being punched to the distance by Sakura.
