WARNING: The following contains spoilers for Boruto: Naruto Next Generations Episode 227, "Team 7's Last Mission?!," now streaming on Crunchyroll.
One of Naruto's most powerful and controversial techniques has always been the "Sexy Jutsu," where he turned into a nude woman covered by mist to distract opponents. He used it in the past to prank Iruka, Kakashi, and Jiraiya in the Hidden Leaf. The technique also ended up as a tool in the war against Kaguya, distracting her with hot guys so he, Sasuke, and Sakura could defeat her. Now the Hokage's son has perfected the move and actually made it much more respectable.
The original technique had some sexist undertones, and then when Naruto and Konohamaru created guys in the "Harem Technique," fans felt it was too gratuitous. Seeing them shapeshift and then use shadow clones to trick opponents like this felt creepy at times, taking away from the bigger picture and what the shinobi techniques laid down for centuries were really meant to be used for.
But here, Boruto proves that he takes his ninja duty a lot more seriously and despite his comical attitude, he knows how to adjust. It's shown when Konohamaru went missing in episode 227, causing Team 7 to track their leader down as they wanted him to be in Konoha when Sarada graduated after passing the new Chūnin Exam.
They realized he was playing possum, though, pretending to be a prisoner in a mountain village that was taken over by Hyōgo, an infamous Kusagakure missing-nin. The terrorists held the people hostage, making them do their dirty work but the thing is, there was no window of opportunity to attack. If Konohamaru had broken free, they'd have murdered the hostages, so he had to bide time.
His plan changed, however, when an older, sultry lady stumbled into the village, weak and begging for help. The blonde, who looked like Lady Tsunade, collapsed on the ground, but with her hair covering her face. Hyōgo went from predatory to suspicious as he couldn't immediately determine her identity. He couldn't imagine anyone getting lost in this desolate area as he went to large extents to keep his new base hidden, and as he probed, the woman smiled.
She then transformed into Boruto, who confirmed Team 7 had already figured out Konohamaru's plan. He was waiting for the fog to hit so he could free himself and attack the terrorists. Thankfully, the trio of young shinobi already did the dirty work, which allowed Konohamaru to deliver the knockout punch to Hyōgo.
Not only did Boruto's move serve as a perfect distraction for his peers to incapacitate the villains, but it also proved sexy doesn't need to be naked, shifting the move from one of style to substance. The fully-clothed substitute was amazingly effective, deceiving someone wanting to exploit a lost victim, and in the process, Boruto added tact and class in a way Naruto never could.
