New Sexy Technique

In an omake included with the second Naruto fanbook, Jiraiya tries to convince Naruto to make his Sexy Technique even sexier in order to give him some writing inspiration. He 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.
