Nuclear Fission Reactor
Land of Fire, year 42 of Konohagakure.
Bright sunlight streamed into Konohagakure's Ninja Academy.
Masaki Kuhara, the Chunin teacher in charge of Konoha's 39th class, faced the blackboard, writing and drawing. All the while, he explained the key points of the Substitution Technique, one of the Three Basic Techniques.
"Of the Three Basic Techniques we're learning, the principle behind the Substitution Technique is..."
In the classroom, Miya sat at his desk, paying no attention to the lesson. Instead, he was...
Gnawing on a deliciously fragrant roasted pig trotter.
The aroma, the taste, the sheer temptation of it—the aggro was through the roof.
Couldn't anyone see the students in the classroom staring longingly at Miya?
More precisely, they were staring at the roasted pig trotter in Miya's hand, swallowing again and again.
"Gulp~ gulp~ gulp~~"
"You can't have any. Bet that makes you mad..."
Miya took in every one of his classmates' reactions, but rather than restrain himself in the slightest, he only grew more brazen...
He even snickered at them in his heart.
Hearing all the gulping behind him and smelling the roast meat in the air, Masaki Kuhara's cheeks twitched.
Miya's behavior was already seriously disrupting the class.
"I know what I'm about to do is dangerous, and I might even end up in the hospital, but as a teacher, I really can't stand it anymore!"
Veins popped out on Masaki Kuhara's face. On impulse, he turned around and shouted angrily.
"Miya Hanama, no eating during class..."
In an instant, the whole class fell silent. Every gaze shifted from Miya to the figure at the podium.
"Has the t-teacher gone crazy? He actually dares to tell Miya what to do?"
"Has he forgotten that our last teacher still has to go to the hospital for checkups every now and then?"
"It's over. The teacher's going to get beaten up, isn't he?"
"Should we get ready to welcome our next homeroom teacher already?"
Cold sweat poured down the faces of many students in the class. A little fearfully, they secretly turned to look at the figure gnawing on the roasted pig trotter—the undisputed tyrant of their class, Miya Hanama.
"Smack, smack, smack~~"
"What did you say?"
Miya took another big bite of meat and, chewing as he looked at Masaki Kuhara, asked somewhat indistinctly.
"Uh..."
"I said, could I please ask you not to eat in class?"
"After all, the other students still need to learn. You're distracting them."
Seeing Miya staring at him, Masaki Kuhara shuddered all over.
A Chunin teacher at the Ninja Academy, being humble in the middle of class.
Was this freaking appropriate? Was it?
His heart pounding wildly and his thoughts nearly in a jumble, Masaki Kuhara silently reminded himself.
That was impulsive! I'm still far too impulsive!
How could I have forgotten Lord Third's instructions?
Why can't I break this habit of acting on impulse?
That Miya is a complete and utter demon king, a madman, and a big eater. He's been eating nonstop every day since shortly after he enrolled.
Eating in class has caused a whole pile of trouble.
And this guy's strength is terrifying. He's a genuine super genius!
Even Kakashi Hatake, the super genius who already graduated early, was no match for him.
To this day, Masaki Kuhara still remembered the heartfelt instructions the Third Hokage had given him before he took over this class a few days ago.
"Masaki, try to be more tolerant of Miya, all right?"
"And keep an eye out for your personal safety."
At the time, Masaki Kuhara had been completely baffled-until he learned what Miya had done.
Cold sweat had nearly soaked him through.
He also remembered what Miya had said on the first day, when he had everyone come up to the podium to introduce themselves.
"My name is Miya Hanama. My hobbies are good food and eating."
"I'll eat anything edible, and I can eat at any time. I turn nothing down."
"So, teacher, if you want to stop me from eating, you'll have to defeat me first!"
Miya had also been holding a roasted pig trotter at the time, standing at the podium and gnawing on it as he spoke, giving him a meaningful look.
Masaki Kuhara knew perfectly well why he had been able to take over this class and become these students' homeroom teacher.
Their previous teacher, Shuichi Tanaka, was currently on injury leave. (Note: injury leave.) He had to go to the hospital for checkups every now and then.
It wasn't just because of his physical condition; it was even more because of his psychological condition.
As for why!
At the time, after Shuichi Tanaka could no longer stand it, he had snatched the roast meat from Miya's hand.
And then, that was it.
Miya had punched him straight into the hospital.
Remember: one punch, just one punch.
As a teacher at the Ninja Academy, Shuichi Tanaka was a genuine Chunin, and Miya had sent him flying with a single punch.
He had suffered serious injuries.
More than the physical pain, what Shuichi Tanaka couldn't accept was that he, a Chunin teacher at the Ninja Academy, had been seriously injured by one punch from his own student!
It had to be said, this teacher Shuichi Tanaka was a little weak psychologically.
So what if he was sent flying? So what if he embarrassed himself in front of lots of people? What was the big deal?
He should have held his head high and faced it bravely. Don't be afraid, don't chicken out!
As long as he wasn't embarrassed, the embarrassment would be someone else's.
That had happened less than two months ago.
How strong was Miya now? Who the hell knew how strong this guy really was!
In any case, he had swept through the Ninja Academy without a match, beaten every school bully with his fists, and become a genius student idolized by countless students.
In short:
He beat up all the teachers at the Ninja Academy.
He kicked around students from every class in the school.
The banner across the top: super school bully.
Having taken over the class under those circumstances, Masaki Kuhara had spent this time treading on eggshells, carefully attending to this lord.
If he dared to stop him, what if Miya accidentally killed him with one punch?
What would he do then?
There'd be nowhere to go to seek justice.
He'd really been too impulsive!
"Stop eating? How could I possibly do that?"
Miya grinned and brought the roasted pig trotter in his hand to his mouth for a bite.
"Smack~ smack~~"
Miya, who had chewed up and swallowed even the bones, was in a wonderful mood.
Inside Miya's body, a bullet-shaped object had formed in his abdomen, at the spot commonly known as the dantian, where Chakra normally gathered when extracted.
The roast meat and bones Miya had just eaten were being crushed by the pale-blue Chakra Particles radiating from that bullet-shaped object, then rapidly absorbed by his body, strengthening his physique bit by bit.
Miya, full name Miya Hanama, was eight years old and had been studying at the Ninja Academy for less than three years.
He was a transmigrator. After entering the Ninja Academy and refining Chakra, he had awakened his golden finger—the Nuclear Fission Reactor.
That's right, the bullet-shaped object inside Miya was the Nuclear Fission Reactor.
After developing it, Miya had put the Nuclear Fission Reactor in his body to use getting stronger by eating.
What did the Nuclear Fission Reactor do?
At its most basic, it could crush, break down, and pulverize his Chakra, turning it into Chakra Particles. Compared with Chakra, Particle Chakra was extremely easy to manipulate, and he could control it however he wished.
Miya had developed a way to use the Chakra Particles to train his physique, using them to accelerate digestion and the absorption of nutrients from food while also strengthening his body.
This was also the fundamental reason Miya had become a big eater and possessed his current strength.
