Five Minutes Later,
His phone buzzed with a text from his mom:
*Be home before five. No detours. No strenuous exercises. I'll call the school if I get whiff of anything.*
"..."
He groaned softly. 'That's right. Grounded.'
He'd barely left the building. The school day wasn't even over.
He didn't have any plans when leaving the house earlier, so there was no possibility of her noticing he was planning anything suspicious—he literally wasn't.
And yet somehow, she still managed to pre-emptively limit every possible freedom he might've considered.
He dragged a hand down his face. "I didn't even do anything…"
Training room access meant nothing if he wasn't allowed to stay on campus late. And if he pushed his luck any further, she'd personally drag him home by the collar.
He sighed and started walking toward class.
'Fine. No gym today. I'll just get to work on something else.' He had other plans beyond just physical exercise. Developing Jutsu was one of them.
In the battle with Overhaul, Yuta's lack of any offensive means had left him in a passive position. If he wanted to participate in the sports festival, just Body Flicker was far from enough.
However, his fundamental problem hadn't changed. The lack of theoretical foundation was a problem hard to overcome quickly. 'I'll head to the library then.' If he couldn't find anything useful, then he would have to brute force his way to a solution, relying only on memory. Hand seals, chakra molding and elemental formulae.
'Hope I find something useful.'
He adjusted his bag and made his way down the corridor, weaving through groups of students migrating to their next classes. General Studies kids chatting. Support Course kids hauling projects.
Hero Course kids… being loud. 'Let's try the other way.'
He thought upon noticing a certain pink haired amd invisible girl among them.
Eventually, he made it to his location.
The quiet of the library wing was a welcome relief.
Thud… thud… thud… His footsteps softened as he crossed into the carpeted section of the building. It was cooler here, dimmer, calmer — a place where even Class 1-A couldn't cause explosions without getting shushed into oblivion.
'Alright. Focus. I need something — anything — on energy manipulation, quirk theory, ki studies… whatever overlaps with chakra molding.'
He rounded the corner and pushed open the library door.
The familiar scent of old paper and disinfectant hit him. Rows of shelves stretched out like a forest of potential answers — or a reminder of how catastrophically little this world understood chakra.
Two students sat at a table whispering over homework. The librarian glanced up, nodded once, and returned to stamping a stack of books.
Yuta slipped inside quietly.
He headed straight to the reference section: Biology of Quirks, Applied Psionics, Metahuman Energy Responses, Internal Support Regeneration…
None of these were chakra, but maybe there was overlap. Even a single parallel was enough to build a theory around.
He skimmed the spines.
'Nothing on internal energy pathways… nothing on molding practices… nothing on elemental conversion…'
He kept moving.
Then—
A single title caught his eye.
"AN INTRODUCTION TO STRUCTURED ENERGY CHANNELING IN ANCIENT MARTIAL ARTS."
".."
'…Okay, that's not nothing ..'
He pulled the book free. Dust puffed off the cover dramatically, as if the universe wanted to remind him the thing hadn't been touched since the Meiji era.
He cracked it open. Diagrams. Breath training. Pressure points.
Five minutes later, 'Nope. That's not right.'
He placed the book back and continued his search.
The result was exactly as he expected. Nothing.
He exhaled slowly, shutting the last book with a soft thunk that echoed louder than it should've.
'Of course. Why would it ever be easy?'
Sitting here expecting UA's library to magically hand him a blueprint for chakra techniques was wishful thinking at its finest. This world didn't even have chi standards, much less chakra theory.
He stared at the shelves for a moment longer.
Maybe one part of him hoped a secret scroll would spontaneously spawn if he glared hard enough.
It didn't. "…Alright. Plan B it is."
Trial and error. His least favorite option — mostly because "error" usually involved mild explosions, smoke, or something catching fire.
'I'll map out what I can make work.' Yuta stepped out of the library with nothing a flimsy notepad, and the creeping realization that if he wanted progress, he'd have to brute-force his way through chakra theory like a caveman reinventing math.
The bell soon rang for dismissal, and by the time he got home, Yuta had already mapped out everything he remembered from the Naruto world on scratch paper.
Poorly drawn hand seals scribbled and arrows pointing at each other like a conspiracy board.
"What is this?"
Yuta blinked.
"Huh?"
Eri said no more, simply pointing to the haphazard writings on his notebook. "Um .. just a school project I am working on. I need to finish it if I want to perform well in the sports festival."
"What's a sports festival?"
"It's a pain in the ass ..."
He had barely finished when
"LANGUAGE!!" A smack landed on his head in full force.
"Ow."
Watching my suffering, Eri giggled in response.
Focusing back on remembering the hand seals, basic Academy Jutsu were the easy ones.
Transformation Technique – Dog → Boar → Ram.
Clone Technique – Ram → Snake → Tiger.
Substitution – Tiger → Boar → Ox → Dog → Snake.
Body Flicker – no seals, just chakra control + intent.
He scribbled them down quickly, letting muscle memory fill in the gaps.
Then came elemental ninjutsu.
Fire Release: Great Fireball – Snake → Ram → Monkey → Boar → Horse → Tiger.
Fire Release: Phoenix Flower – Rat → Tiger → Dog → Ox → Rabbit → Tiger.
Fire Release: Dragon Flame – Horse → Dragon → Rabbit → Tiger.
Water Release: Water Bullet – Tiger → Ox → Monkey → Rabbit → Boar.
Hidden Mist Technique – no seals, just chakra into moisture dispersion + environmental saturation.
He hesitated. Hidden Mist might be doable, even if he didn't have the affinity for it, but he'd table that.
Earth Release: Earth Flow Spears – Tiger → Hare → Dragon.
Earth Release: Earth Dome – Tiger → Hare → Boar → Bird → Rat.
Wind Release: Great Breakthrough – Ram → Snake → Horse.
Wind Release: Gale Palm – no seals, just directional chakra emission.
Lightning Release: Chidori – Ox → Rabbit → Monkey.
Principles: high-speed thrust + concentrated lightning chakra + tunnel vision risk.
Lightning Release: Lightning Beast Tracking Fang – Snake → Ram → Dragon → Tiger → Ox → Dog.
And the one he absolutely could not use—
Lightning Release: Kirin – relies on natural lightning, basically impossible here.
Still, he wrote it down. Knowing the theory wasn't harmful.
Finally, he scribbled out the most infamous chakra manipulation technique:
Rasengan – chakra rotation + shape transformation + stable compression.
No seals. Pure molding.
'Thankfully, I no longer have the reserves of a depressed houseplant.'
It looked solid on paper.
In execution?
He spent most of the night kneeling on his bedroom floor, palms pressed together, trying to mold chakra into something—anything—while keeping the output microscopic.
He wasn't stupid enough to try Fire Release indoors. Or Lightning. Or Wind. Or anything explosive. So he stuck to the harmless ones. Transformation Jutsu, Shadow Clones, and Substitution. Facts proved he had overestimated himself.
The greatest result he could get was a wavy image from Transformation and a puff of smoke from clone Jutsu.
He tried adjusting his chakra ratio, compressing more tightly, loosening the circulation, even attempting to rotate his chakra clockwise (which made no sense but felt spiritually correct).
Nothing.
By midnight, he faceplanted onto his bed.
'…Okay. Day one: I have learned absolutely nothing.'
__
Day Two came in the blink of an eye.
This time, he added theory.
Chakra ≠ Quirk energy
Chakra circulates like blood
Chakra molds like clay
Hand seals = mental scaffolding
Transformation → heavy on shape manipulation
Clone → low chakra, high precision
Elemental → nature manipulation + shape + ratio control
He wrote the formulas out again, this time "translated" into UA physics:
Internal energy → convert → external effect
Conversion efficiency = chakra control × mental image
Stability = hand seals × flow alignment
This time, he wasn't progress. However his biggest gain, was figuring out why nothing worked.
In theory, with his perfect chakra control and knowledge of most hand seals, he should be able to perfectly recreate any Jutsu he remembered.
However, Trial and error said otherwise.
Performing Jutsu required more than just seals. The Hand Seals only helped properly summon and mould chakra.
Meaning it helped those with low chakra control get past the first hurdle. However, it did not tell him the ratio of chakra to use nor the pathways in which they should flow through. In the Ninja world, Ninjas possessed Tenketsu and numerous chakra pathways.
Without this knowledge, reproducing Jutsu in an instant wash a pipe dream.
'My current situation situation ... Is probably worse than Naruto's, isn't it?'
At this points, his notes looked like the diary of a mad scientist.
'I need another plan.' With six days left, Yuta couldn't afford to lay all his eggs in one basket. 'Time for plan C then.'
If chakra theory refused to cooperate, then he'd make the Sports Festival cooperate instead. The way to achieve that? His quirk.
That, at least, worked cleanly. No hidden theory. No ninja mechanics he couldn't access.
But for that, he needed ..
'Support gear.'
Not weapons, exactly. U.A. would never approve Kunai and Shuriken being used. Ironic when Aoyama was literally blasting Mina with a laser that could destroy steel during said festival.
But tools he could mark that could support movement or utility or misdirection. Something durable.
There was only one place to get that.
The Support Department back in school.
It wasn't ideal, but if he could get Hatsume or one of the other Support maniacs to build something simple—weighted tags, markers, anything conductive or trackable—he could use his Quirk without burning himself out. But getting the materials wasn't the complicated part. Asking for them was.
If he remembered right, he would need to fill in paperwork to use any support gear during the sports festival. Something Iida would learn after being tricked by a certain pink haired gremlin.
Still… if he didn't ask, he'd have nothing.
The better the materials, the better his chances of winning.
He let out a long breath, closing his notebook.
'Tomorrow, I'm going to the Support Course. One way or another, I'm walking out with something I can use.'
