5 & 6. Yamato and Kakashi
This incident began when Konohamaru came to see Naruto to show that he had successfully completed the second stage of mastering the Rasengan. At that time, Naruto was taking a break from his wind chakra training, which was being supervised by Yamato and Kakashi, with the goal of splitting a waterfall.
Konohamaru then used Oiroke no Jutsu, transforming himself into a seductive woman. He proudly demonstrated his success in the second stage of training by popping a rubber ball. Naruto praised Konohamaru’s achievement but looked puzzled by Konohamaru’s use of Oiroke no Jutsu.
Naruto’s bewildered reaction made Konohamaru feel annoyed, as he believed his hard work wasn’t being appreciated enough. Still in the form of a seductive woman, Konohamaru began pouting and swaying his body in an exaggerated manner.
From a distance, Kakashi and Yamato watched the interaction between Naruto and Konohamaru. However, when they saw Konohamaru in Oiroke no Jutsu mode swaying his body, both Kakashi and Yamato were instantly launched into the air like rockets, accompanied by uncontrollable nosebleeds.
