Hiroki had just finished writing and debugging his new code when a sudden thought struck him.
Wait—What's the target chakra output level needed to stick without breaking the wall?And what's the unit of chakra in the first place?
He frowned. That was a real problem.
He looked up at Orochimaru."Teacher Orochimaru," he asked seriously, as though discussing a scientific formula, "for this technique—how much chakra should be focused on the soles of the feet? Is there a standard value?"
The moment he said that, both Nawaki and Kushina froze mid-practice. Even Orochimaru, whose face rarely showed emotion, blinked in mild surprise—his golden eyes flashing with curiosity.
Standard value?
What even was that supposed to mean?
Ninjas didn't measure chakra—they just felt it.They thought, "Yeah, this much should do," and somehow it worked.
Who in the world tried to calculate it?
Orochimaru had trained countless students, yet no one had ever asked him such a question.Even the hidden ANBU and Root operatives observing nearby were taken aback.
A ninja's chakra control was instinctive—an art built from years of experience.Just like breathing.Who calculates exactly how many liters of air they inhale per breath?No one.
Even if a person could sense their total chakra capacity, no one ever quantified it.They only compared—"That guy has twice my chakra," "Naruto's is a hundred times Kakashi's"—rough estimates, never numbers.
This question, though… was brilliant.
No—revolutionary.
It was like a weightlifting contest where no one knew how heavy the stones were—they just lifted at random and hoped for the best.How meaningless would that be?
For the first time, Orochimaru realized he had no answer to give.And yet… the question intrigued him.
If he wanted to master every ninjutsu in existence, wouldn't it be much easier if chakra could be standardized?
After a long moment of thought, he finally offered the most precise estimate he could manage."Probably… about one-sixth of the chakra needed for a basic Transformation Jutsu. Maybe even less."
"But that's only my personal experience," he added. "You'll need to adjust it yourselves. I've used the Substitution Technique for years, so my chakra flow differs from yours. The amount also scales with body weight and size—so one-sixth might not apply to you."
When Orochimaru finished, he studied Hiroki closely.He wanted to see how this boy—who dared to ask such a question—would put theory into practice.
Of course, once Orochimaru returned home, he'd define his own standard…But even that wouldn't compare to Hiroki's first attempt to quantify chakra itself.
"I see." Hiroki nodded slowly. The answer was vague, but it was enough.
He closed his eyes, returning to his inner "interface."
Time to define a base chakra unit.
Just like data: a bit, a byte, a kilobyte—each layer built on the smallest measurable piece.Orochimaru's example, the Transformation Technique, could serve as a reference… but it wasn't constant. Skill level affected efficiency, so it couldn't be a true baseline.
It would be like using "percentage of hard drive used" instead of bytes to measure file size—too many variables.
He needed something universal.A fundamental chakra unit.A "bit" for ninjutsu.
So, he opened a new file in his consciousness:
[Chakra_Unit_Definition_v0.1.txt]
He began outlining his thoughts:
The smallest measurable unit of chakra is produced by the combination of physical and spiritual energy within the body's 130 trillion cells."Physical strength" forms the base of Taijutsu.When converted, it becomes chakra, which can be molded into techniques through hand seals.
But how much chakra could one unit of cellular energy produce?How much was lost in conversion?No data existed.
So Hiroki decided to define his own unit experimentally—starting with the Transformation Technique.
He would measure how much chakra a single use consumed, then use that to define his base value.
He formed a seal, activated the jutsu, and transformed—into none other than Orochimaru himself.
Poof.
A second, identical Orochimaru appeared. No one reacted—they were all waiting to see what Hiroki would do next.
He canceled the transformation, eyes still closed, thinking deeply.
//========================================
// Establishing Chakra Measurement System
//========================================
// Step 1: Determine the chakra cost of Transformation
Function DetermineTransformationCost() {
Before = CurrentChakraPercentage;
PerformTransformation(target: "Orochimaru");
After = CurrentChakraPercentage;
Consumption = Before - After;
return Consumption;
}
// Step 2: Define basic chakra unit ("card")
// One standard Transformation = 100 cards
Function CreateCardSystem() {
TransformationCost = DetermineTransformationCost();
TotalChakraPool_Card = (100 / TransformationCost) * 100;
UnitCard_Percentage = TransformationCost / 100;
Record("Transformation Cost: " + TransformationCost + "%");
Record("Total Chakra Pool: " + TotalChakraPool_Card + " cards");
Record("1 card = " + UnitCard_Percentage + "%");
return TotalChakraPool_Card;
}
// Step 3: Calculate Chakra Needed for Wall Climbing
// Approx. 1/6 of Transformation cost (based on Orochimaru's 60kg weight)
Function CalculateWallClimbCost(MyWeight) {
BaseTransformation = 100;
BaseWeight = 60;
WeightFactor = MyWeight / BaseWeight;
BaseClimbCost = BaseTransformation / 6;
ActualCostPerSecond = BaseClimbCost * WeightFactor;
SafeCost = ActualCostPerSecond * 1.2;
return SafeCost;
}
// Step 4: Real-time Chakra Monitoring
Global InitialChakra_Card = 0;
Global ConversionRate = 0;
Function InitializeSystem() {
InitialChakra_Card = CreateCardSystem();
ConversionRate = InitialChakra_Card / 100;
}
Function GetCurrentChakra_Card() {
return CurrentChakraPercentage * ConversionRate;
}
Function DisplayChakraStatus() {
CurrentCard = GetCurrentChakra_Card();
ConsumedCard = InitialChakra_Card - CurrentCard;
Percentage = (CurrentCard / InitialChakra_Card) * 100;
Display("Remaining: " + CurrentCard + " cards (" + Percentage + "%)");
Display("Consumed: " + ConsumedCard + " cards");
}
After initializing the system, Hiroki entered his parameters:
Hiroki's weight = 35 kg
WallClimbCost = CalculateWallClimbCost(Hiroki's weight)
Record("Wall Climb Cost: " + WallClimbCost + " cards/second")
The results appeared in his inner display:
[System Log]
Transformation Cost: 3.2%
Total Chakra Pool: 3125 cards
1 card = 0.032%
Wall Climb Cost: 11.67 cards/sec
He exhaled slowly.
Now he knew.
His total chakra capacity was 3,125 units.Climbing a wall would consume about 11.67 per second.Theoretically, he could maintain wall-walking for roughly 268 seconds—about four and a half minutes.
Of course, that was only the theory.
Now came the real test.
Hiroki looked up at the wall and lifted his foot.This time, he didn't "feel" the output—he controlled it precisely, feeding chakra to his soles at 11.67 units per second.
Every eye—Orochimaru's, Nawaki's, Kushina's, even the hidden ANBU—was locked on him.
Would he fall?
Or—
He stepped forward.
…
Success!!!
The suction felt a bit weak at first, his body swaying slightly—but within seconds, he stood steady.
Just like that.
He'd done it.
On his first try.
