The next day, inside the arena.
Yuu's match proceeded as scheduled. The venue was packed, and the cheers were deafening even before the fight began.
Having reached the 100th floor, in theory, the opponents Yuu matched against should have seen a qualitative leap in skill.
However, once the fights actually started, those martial artists who looked so imposing beforehand couldn't last a single move against Yuu.
Just a simple, unflashy punch. Even if a few particularly robust fighters managed to stay conscious after taking the hit, they were still knocked out of the ring and declared the loser.
Today was no different.
Within five seconds of the referee signaling the start, Yuu used his teleportation-like speed combined with a straight punch to instantly KO his opponent. Some spectators blinked and missed the entire match.
In the crowd, only one person—a young man in a shirt and glasses—managed to see Yuu's starting and ending poses. But like Killua, he couldn't see anything during the actual attack process.
"Too fast..."
The bespectacled man was named Wing. He was a seasoned Pro Hunter and the prized disciple of Biscuit Krueger.
He spent most of his time at Heavens Arena, watching popular matches daily to study the fighters' techniques.
At the same time, he was on the lookout for a child with the right aptitude and temperament to become his future disciple and inherit the Shingen-ryu school of martial arts.
Now, having stumbled upon Yuu—a child who looked young but possessed formidable strength—Wing couldn't help but pay extra attention to him.
Watching Yuu leave, Wing focused "Nen" into his eyes to observe carefully.
"Based on his total aura volume alone, he doesn't seem to be a senior disguising his age like Master..."
"If he really is only a teenager as he appears, to have cultivated his Nen to this level... he must be a genius found only once in a hundred thousand—no, a million people."
"I just wonder if such a talent has a teacher guiding him from behind the scenes."
Wing returned to his residence, bringing with him the tape of the earlier match.
He hadn't forgotten his purpose for watching.
It wasn't to recruit a disciple.
It was to decipher the moves Yuu was using.
Specifically, to study his footwork, determine which school he belonged to, and figure out if he had a master.
Furthermore, he hoped to learn from it and integrate it into his own style to improve his strength.
However, since the principle behind Yuu's "teleportation" was using "Blue" from the Limitless Technique to compress space for high-speed movement...
Even with the aid of "Nen," trying to track the movement trajectory with the naked eye remained difficult.
At most, one could only perceive the instant he began to move.
...
After rewatching the tape repeatedly for nearly an hour, Wing hadn't figured out a single thing. Instead, his mind was even more confused.
"This isn't scientific..."
Wing frowned, deeply puzzled.
In his mind, the fastest person alive was his master's master—the current Chairman of the Hunter Association, Isaac Netero.
According to his master, Biscuit...
Chairman Netero's power came from years of bitter training in the deep mountains, perceiving and realizing a martial art born of "gratitude."
Even Netero's punches, which exceeded the speed of sound, had a movement trajectory that Wing believed could be perceived.
Even if you couldn't see it clearly, it definitely existed.
But this young fighter he had encountered today upended his understanding of martial arts.
No technique, no explosive physical power, and no special state achieved through bitter training like Chairman Netero.
It was a special ability that couldn't be captured even with "Gyo."
Thinking of this, Wing had no choice but to seek help from his master, Biscuit.
So, he transmitted the contents of the tape to his master. After confirming she received it, he dialed Biscuit's number.
Beep.
The call connected.
Wing immediately stated his request.
"Master, regarding the content of this recording, please watch it a few times..."
"I absolutely need to know how that black-haired boy can execute such exquisite footwork, and why his movement trajectory is impossible to capture even with 'Gyo'."
"Because you're too weak," Biscuit said bluntly from the other end.
"I didn't expect that after all these years of training, you'd still be outshined by a boy. You've really regressed, Wing."
Wing replied helplessly, "It's precisely because the boy's displayed aura is far inferior to mine, yet I can't see his movements, that I'm urgently asking for your help, Master."
Biscuit was silent for a moment, then asked in a low voice:
"How old does the boy look?"
"About thirteen or fourteen," Wing said.
"Thirteen or fourteen... about the same age as that damn brat."
Biscuit's words instantly triggered a connection in Wing's mind.
Before Wing could speak, Biscuit pressed on: "What are the boy's characteristics?"
"Physically, he's not particularly special or robust... but what's noteworthy is his 'Nen.' It appears extremely stable, clearly the result of specific mental refinement," Wing explained.
"That's most likely him."
Biscuit said angrily, "Wait for me to finish watching the tape. I'll give you an answer shortly."
"Barring any surprises, I'm coming to you immediately. Remember... whether or not he turns out to be the person I'm looking for, you must find a way to keep him there. At least until I arrive."
Hearing the sheer rage in Biscuit's voice, Wing said resignedly:
"It seems that boy really left quite an impression on you, Master..."
Hearing this, Biscuit let out a furious hmph and hung up.
On the other end, Biscuit, who had originally planned to search for gems in some ruins, changed her itinerary because of this single phone call.
Ten minutes later.
After watching the tape provided by Wing, Biscuit—perhaps due to psychological suggestion—felt more and more that the black-haired boy's figure was identical to the "Yuu" in her memory.
Although there were obvious changes in height and aura, given that six months had passed, such improvement was normal.
Thus, the anger that had been suppressed in Biscuit's heart for so long was uncontrollably ignited and began to rise.
Unconsciously, she cracked her knuckles, making crisp popping sounds.
Biscuit had made up her mind. No matter what excuse he had for ghosting her for six months...
She decided that the moment they met and she confirmed his identity, she would teach that arrogant brat a lesson he wouldn't forget.
Then, a dark smile floated onto Biscuit's face, accompanied by a creepy "Hehehe" laugh.
...
"Why do I suddenly feel like I'm being targeted by something terrible..."
At that moment, Yuu, who had just finished collecting his prize money and was counting his assets in his room, suddenly felt a wave of intense malice from somewhere unknown.
It made him feel quite uncomfortable.
