Inspired by Chapter 37 of Naruto's Kit by brown phantom. If you look, you'll find the specific line.
It had been a week since Naruto had made the promise to bring Sasuke back no matter what the cost. Kotetsu Hagane and Izumo Kamizuki were once again on guard duty at the main gate. So far the day had been fairly normal. No invasions, just a couple C-rank missions returning, and a couple civilians asking about their children. Nothing of note.
Shortly after lunch, something of note occurred that caused the two to wonder just what were in those sushi packs they had eaten. First they heard some sort of faint string instruments raising up over the horizon, then there was accenting notes that rose up with an underscoring drum. As the music grew louder, they first saw it. A sea of orange approached the gates, each one playing a different instrument, making the odd music.
That's when they heard a voice raising from the center, it was Naruto alright, but he was counting in a strange way. "One, two, three, and... one, two, three, and..." A moment later, they saw something that really made them wonder about what was in those meals. In a dance that was mostly circling around each other, Naruto and Sasuke breezed past, laughing and doing that strange count.
After all the clones had passed through, one final one approached with paperwork. "Naruto Uzumaki, returning from S-rank retrieval mission with successful results."
"What the hell was that?" Kotetsu asked while pointing at the apparently infectious dance, as others began joining in.
"Don't tell me you guys never heard of Waltz-no-jutsu!" the clone gasped in shock. "Matilda-sensei told me it was the best jutsu out there! And she was right!"
