The moment the three floating UI messages appeared before Hanyū Yuuma, he fell quiet.
So the master–disciple System…It could generate Training Quests?
Yuuma narrowed his eyes.Strange. He'd planned training before—strict, structured regimens—but the System never responded like this.So the trigger wasn't him.
It was the disciple's desire.
A genuine, burning want.
And looking at Obito's trembling, hopeful eyes… Yuuma could feel that desire like heat on his skin.
"Teacher Mu Yue—please!" Obito bowed hard enough to smack his head into the dirt."If you help me get first place… I'll give everything in training! Anything you say—I'll do it twice over!"
He still remembered the sting of losing to Kakashi in front of Rin.He remembered the shame vividly, like a burn scar on the heart.
Yuuma sighed and placed two fingers lightly against Obito's forehead.
"Fine."
Obito's eyes went round, then bright like a kid who suddenly saw the sun."Teacher! You're the best teacher in the world—no exaggeration!"
"Save that praise until after you win." Yuuma flicked Obito's forehead.
"Hehe… but it's true."
He really meant it.In all his years at the Academy, Obito never understood what made a "good teacher."
But Yuuma taught clearly, stayed patient, never mocked anyone, and never discouraged those who struggled.To Obito, that was more precious than talent.
"So… what're you going to teach me?" Obito asked, eager.
Yuuma turned toward the river."Fire Style: Great Fireball Technique."
Obito drooped immediately."I already know that one… I used it last competition and only got 20 points."
Back then, Obito's Fireball barely hit the judges' minimum scoring threshold.Then Kakashi stepped forward with an Earth Release that reshaped the entire arena terrain and instantly snatched full marks.
Yuuma raised a hand."You want power? Then stop thinking like a kid.Among the jutsu you're capable of learning right now, the Great Fireball has the highest destructive potential."
Obito opened his mouth to protest—
—but Yuuma was already forming seals.
Fast.Precise.Effortless.
"Fire Style—Great Fireball Technique."
His chakra surged like a detonating furnace—Yuuma inhaled—
—and expelled a blazing inferno.
A massive sphere of flame roared out of his lungs, swelling and swelling until it towered ten meters tall.
A fireball the size of a two-story building tore across the riverbank.
Shisui froze.Guy stared openly.Obito nearly fell backward.
It wasn't a fireball.It was a superheated miniature sun.
"So strong… even stronger than the one I saw before…" Shisui whispered, remembering the secret glimpse of Yuuma training weeks ago.
Obito could only gape.
"That's… THAT's the same jutsu I learned?"
His own Fireball was the size of a pumpkin.Yuuma's was the size of his house.
The giant fireball slammed into the river, exploding into a white tidal wave of steam.Mist engulfed the training ground—Yuuma dispelled it with a casual Wind Release flick of his fingers.
He turned back.
"So? Enough power for you?"
Obito nodded frantically."If mine looked even a quarter that big—I'd win for sure!"
Yuuma's inner voice quietly disagreed.It was pure showmanship. Wasteful. And extremely chakra-hungry.He'd burned nearly 1,000 chakra points just to look cool.
And realistically, Fireball almost never hit human targets anyway.
He still remembered seeing someone analyze 700+ episodes of ninja combat.Result:Fireball had a 0% hit rate on humanoids.
The most cursed accuracy stat in existence.
"Well then," Yuuma said. "Your turn."
Obito inhaled, formed seals, and released—
—a fireball the size of two soccer balls.
Even Guy winced."Obito… that's… uh…"
"Kai. Spare me." Obito deadpanned.
Yuuma didn't laugh.
"There are three reasons your Fireball looks like that.
First: your chakra control is terrible.Second: your Fire-Attribute Transformation is weak.Third: your Fireball proficiency is low."
Yuuma pulled out a slim notebook.
A manual.
He handed it to Obito.
"This is my Fire-Attribute Transformation training method. Read it, memorize it, drill it. It'll fix your nature-change problem."
Obito clutched it like a holy relic.
Then—
[System Notice]You have gifted your disciple the Fire-Attribute Chakra Conversion Manual.A major gratitude bonus has been triggered.Reward Granted: Fire Style — Ash Storm (Mastery Level)
Yuuma's breath hitched.
A mastery-level ninjutsu?Already?
And not just any technique.
Fire Style: Ash Storm.
A B-Rank annihilation skill once used by Kakuzu's fire mask.Combine it with his wind technique Suppress, and he could carpet a forest in flames.
Training memories downloaded into Yuuma's mind like a flood of data.
For a moment—just a moment—he felt like a veteran hermit-ninja who had trained the same jutsu for thirty years until it became an extension of his body.
Obito hugged the manual to his chest.
"I'll read it every day, Teacher! Every single day!"
"Good. Then let's begin."
Yuuma pointed at the river.
"For starters, we fix your chakra control."
Climb tree.Walk water.
Then—
Enhanced Water-Walking Hell Mode, a training method refined on Asuma and perfected through torment.
Obito shivered.
He remembered exactly what Yuuma put Asuma through last weekend.
But he puffed out his chest and nodded.
He asked for this.He would endure it.
Today, the quest began.
