QP.
In the original Prince of Tennis World Cup arc, he was the second-in-command of the German team.
He had no real name—only the initials "QP," short for "Quality of Perfect."
But his past was far from perfect.
An orphan abandoned as an infant, he was sent to the German Tennis Training Center, where "QP" originally stood for "Quark Puppe"—"an insignificant puppet."
This shaped his cold, isolated personality, making him an outcast.
At age five, while learning the basics, his demeanor alienated the assistant coaches. Even the center's former principal considered sending him to an orphanage.
But then, Raitlair stepped in.
Recognizing QP's talent, Raitlair risked his job to protect him, even accepting menial work just to stay by QP's side. That devotion forged the "Quality of Perfect" the world now knew.
After graduating elementary school, QP was scouted by the Elite Club.
In his first year, he was hailed as the "masterpiece of elite training," crushing every opponent and standing only below the club's strongest—Jürgen Volk.
In fact, during middle school, QP's performance surpassed Volk's at the same age.
Volk himself once declared:
"This guy might become the closest thing to a God of Tennis."
That statement skyrocketed QP's status in the club.
As for Raitlair?
He went from janitor to principal of the training center—all because of QP's rise.
To QP, Raitlair wasn't just a mentor. He was family.
Which was why, when Raitlair called, QP always answered.

### Reunion at the Training Center
After a 30-minute drive, QP arrived.
The gates swung open automatically. A security guard waved. "Hey QP! Long time no see!"
QP nodded silently and walked past.
He never was one for conversation. The guard knew that, so he didn't mind.
QP surveyed the familiar campus—no nostalgia, no hesitation. He pulled out his phone and dialed Raitlair.
"Teacher, I'm here. Where are you?"
"Already back? Wait there—I'll come down."
Half a minute later, Raitlair rushed out of the office building. His eyes softened at the sight of QP.
"You've grown taller again," he chuckled, reaching out to ruffle QP's hair.
QP dodged, cheeks faintly pink. "Teacher, I'm not a kid anymore."
"You're in middle school! At the training center, you wouldn't even be graduating yet!"
Raitlair grinned. "Come on. Let's go meet that boy."

### The Search for the Auras
As they walked toward the courts, QP cut straight to business.
"Any progress on finding players with the 'Aura of Love' or 'Aura of Fortitude'?"
Raitlair sighed. "The Elite Club hasn't found either yet. There are rumors of 'Aura of Love' abroad, but 'Aura of Fortitude'..."
He patted QP's shoulder. He knew how badly his student wanted to evolve—to become the true "Quality of Perfect."
Among the Three Auras of Tennis, "Aura of Love" and "Aura of Resignation" were relatively common.
But "Aura of Fortitude" was vanishingly rare. Even the Elite Club's vast network couldn't track it down.
"Don't rush. These things take—"
BOOM!
A deafening impact cut him off.
Both turned toward the junior training courts—where a crowd of students lay groaning on the ground.
At the center of the devastation knelt one boy, terrified.

### Yoru's Wrath
In less than an hour, Yoru had wiped out the training center's middle schoolers.
He wasn't one to hold grudges. He settled them on the spot.
The defeated players bore injuries of varying severity.
Yoru's gaze swept over a group of elementary students watching from the sidelines.
"You kids want a turn?"
"NO!"
They shook their heads furiously. Even the middle schoolers got wrecked—they weren't stupid enough to challenge him.
"H-He's insane..."
"Look at Hopkins! He's barely breathing!"
"Why's someone this strong even bothering with us?"
"Because Hopkins picked a fight! That guy's the principal's VIP guest!"
"Idiot!"
The kids whispered, too scared to meet Yoru's eyes.

### The Arrival of Perfection
"What happened here?!"
Raitlair and QP approached, the former shooting a questioning look at Amos.
The driver quickly explained—including Hopkins' instigation.
Raitlair wasn't surprised. If anything, he looked amused.
"Teacher," QP said, eyes locked on Yoru, "is this the one you wanted me to take to the Elite Club?"
His instincts flared.
Beneath Yoru's lean frame lurked explosive muscle density.
Almost as if sensing the scrutiny, Yoru glanced up.
Their eyes met.
"So you're here," Yoru smirked. "The 'Quality of Perfect.'"
Instantly, QP's stats materialized before him:
[Name]: Aogiri (QP)
[Age]: 13
[Techniques]:
- Personal Five Dimensions (Lv. 7)
- Tennis Fundamentals (Lv. 7)
[Talent]: Quality of Perfect
[Combat Power]: ★★★★☆ (8-Star)
[Quality of Perfect]:
- Perfectly develops all abilities.
- Extracts experience from matches against the Three Auras.
- Each aura absorbed boosts Five Dimensions & Fundamentals by a % in real combat.
- Currently Absorbed: Aura of Resignation.
(Note: Collecting all Three Auras evolves "Quality of Perfect" into "Ultimate Quality.")

### Pure. Terrifying.
QP had no flashy techniques—just flawless fundamentals and perfectly balanced stats.
Though rated 8-Star, his real combat power likely reached mid-tier 8-Star thanks to his talent.
If Ralph didn't have my guidance, he'd probably lose to QP right now.
Yoru guessed Ralph only became a true top-tier (T1) player after the first World Cup, once he refined his weaknesses and matured physically.
But one detail puzzled him.
"Aogiri?"
That wasn't QP's name—it was a private nickname between him and Raitlair.

### The Challenge
"Sorry about this, Nan," Raitlair said, ignoring the groaning students. "Let me introduce QP—my finest student. He'll take you to the Elite Club."
Pride laced his voice.
"QP," the boy said, extending a hand.
Yoru shook it. "If Raitlair calls you his best, I'd love to see it for myself."
"That might not be wise..." Raitlair hesitated.
He only knew Yoru's strength through Nanjiroh's stories.
But QP?
Once a match started, QP didn't hold back.
Raitlair didn't want to explain to Nanjiroh why his son got hospitalized.
QP, however, remained calm.
"I haven't played my daily matches yet. Let's see if you're worthy of visiting the Elite Club."
Yoru grinned. "Wouldn't miss it."
At that moment—
[Ding!]
A system notification chimed in Yoru's mind.
