Naruto: All depends on the Nine-tails Fox

"That's not right." However, Minato quickly reacted.

"I've seen the fastest users of the Body Flicker Technique, and they can definitely catch me off guard. It's not just the fastest Shunshin of all; even Kakashi's technique occasionally makes me miss it! But!" Guy suddenly clenched his fists, tears streaming down his face as he looked up at the sky. "Compared to them, how old are you? Yet I can't see through your Body Flicker Technique!"

"Ah, this... I didn't mean to..." Naruto didn't expect such a drastic shift in Guy's tone. Just as he was about to explain his actions, he suddenly heard Guy shout into the sky, "Indeed! The youth of today burns with passion! The badge of youth is blood and sweat; I want to ignite my passion too! Hey, kid, what's your name?"

"I... I'm Uzumaki Naruto."

"Naruto-kun! How on earth did you learn such an impressive Body Flicker Technique?" Guy was clearly excited now, completely ignoring Hinata and the others. He eagerly grabbed Naruto and began asking a barrage of questions. "Is it something you practiced from a young age? Do you run hundreds of kilometers in the forest every day? No, thousands of kilometers? Come on, take me to try it out!"

Without giving Naruto any chance to refuse, he leapt into the dense forest of the training ground, disappearing right in front of Hinata and the others.

They were left looking at each other in disbelief.

"Are we... okay?" Hinata's brother, Heizo, turned to Itai, feeling incredulous. "Did that little brat just save us?"

"...While I don't think Guy means any harm, you do have a point. Anyway, Miss, let's head back for now," Itai said, suddenly recalling something, and spoke to Hinata.

"Naruto-kun..." Hinata gazed with a hint of worry in the direction where Guy and Naruto had vanished.

Unbeknownst to them, a few masked ANBU members were hastily following after them.

In the dense forest, Guy was dragging Naruto around, leaping and bounding with a speed that was both impressive and a bit comical.

Especially with little Naruto being lifted by Guy, he flailed like a streamer, dizzy enough that his eyes were replaced by swirling patterns.

"Phew! Six minutes and thirty seconds, I've broken my previous record! What a wonderful warm-up!"

Finally stopping as Naruto was about to be dizzy, Guy wiped the sweat from his forehead, letting out a contented sigh.

"Ugh... Wah!" After finally getting his feet on the ground, Naruto immediately threw up, his undigested breakfast spilling out of him.

Naruto felt the world spin, stars filling his vision.

"Okay, there shouldn't be anyone else around." Guy surveyed the surroundings, confirming that the ANBU tails he had sensed earlier had not followed them. He turned to Naruto, his playful expression fading into seriousness.

"Uncle... what are you going to do..." Naruto wiped his mouth, looking up in shock.

After that whirlwind of speed, was this browed man really human?

"I need to tell you something." Guy's expression was stern and serious, and he didn't mention the earlier excitement about Naruto teaching him the Body Flicker Technique.

Meanwhile, within the Hyuga clan.

Hyuga Hiashi listened to Heizo and Itai's report, frowning. "A very impressive Body Flicker Technique?"

"Yes, the Nine-Tails kid... uh, I mean, Uzumaki Naruto's Body Flicker Technique is astonishing; he was able to protect Miss Hinata from the hands of a Jōnin. Head of the clan, the Leaf Village ninja openly attacked Miss Hinata..."

"I already know. You can leave." Hiashi waved his hand, not allowing them to finish, then seemed to remember something as he exited the room. He gave a command that left the two bewildered. "By the way, you can spread the word that Uzumaki Naruto can use the Body Flicker Technique; try to let as many people as possible know about it."

As Hyuga Hiashi left the room, Heizo and Itai exchanged glances. "Why do you think the head of the clan wants us to do this?"

"Could it be that he wants us to spread this news so he can exert pressure on the higher-ups in the Leaf Village? After all, Guy is a special Jōnin of the Leaf; maybe he wants to leverage public opinion..."

"Never mind, the clan head has given an order, so we just do it."

Meanwhile, standing outside the door, Hyuga Hiashi displayed a hint of nostalgia in his Byakugan eyes—

"Is it your Flying Thunder God Technique?"

"I sincerely apologize for my curiosity exposing your impressive technique earlier." Guy patted Naruto's shoulder, fully aware of how sensitive Naruto's identity was. "But thankfully, not many people know about it, so they shouldn't recognize the technique. Just remember, it's best not to use this technique in front of others, and keep in mind that your Body Flicker Technique is extremely powerful, got it?"

Indeed, Guy was pretending to be clueless to protect Naruto. In truth, he had recognized the technique the second time Naruto used it.

It was the signature space-time ninjutsu of the legendary Fourth Hokage, the Yellow Flash, Minato Namikaze—Flying Thunder God!
