"Alright class, find the value of x." 

I sighed again, tapping my fingers against the desk. This is painful. Every second spent in this classroom felt like a complete waste of my time... My mind worked too fast for this kind of slow-paced learning. Ever since N.E.O. upgraded my cognitive functions, these lessons had become nothing more than an insult to my intelligence.

I now had both eidetic, and photographic memory... Memorizing things had become redundant, and calculating them were were, well; easy...

I glanced at the chalkboard, barely paying attention, and immediately solved the equation in my head. It wasn't even difficult—it was just there, the answer appearing in my mind the moment my eyes registered the numbers.,=

"It's 32, Sensei." I answered more flatly than I wanted to. This must be what Shikamaru feels like all the time.

Unsurprisingly, the room fell silent for a minute.

I could see sensei blinking, clearly surprised, "That's… Huh? Hayatou, you—you already solved it?" He sounded genuinely confused, like he couldn't wrap his head around how I had done it so quickly. I couldn't blame him; this was my first time showing off my intelligence to anyone really.

"Hayatou… how did you solve it so quickly?"

I sat up a little, stretching my arms before giving him a casual yet respectful answer. "Well, Sensei, it's just a straightforward algebraic expression. You set both sides equal to each other, then isolate the variable by performing inverse operations. In this case, you distribute first, eliminate the constants, and then divide to get the final value."

The teacher blinked, his chalk frozen midair. "You didn't… need to write anything down?"

I shook my head. "No, Sensei. The equation was simple enough to solve mentally. Once you recognize the patterns in number relationships, it's really just a matter of breaking it down into smaller steps... For example, you set up the equation and visualize the balance—if you subtract the same value from both sides, you maintain equality. The coefficients already hints at the final solution, so you only need to mentally track a few changes from there."

A few students glanced at each other, whispering.

"He visualized the equation?"

"I didn't even finish writing it down yet…"

"What does he mean by patterns?"

The teacher coughed into his fist, clearly trying to process what he had just heard. "I… see. That's quite an advanced way of thinking, Hayatou."

I simply nodded. "It's just logic, Sensei. Mathematics follows extremely strict structural rules, and once you recognize the fundamental principles behind them, problems like these become pretty predictable."

More silence, as expected... The teacher looked at me for a moment longer, then gave a slow nod. "Very well. That's… an impressive way of explaining it. Well done... However, what about this problem."

The teacher, still visibly processing my explanation, hesitated for a moment before turning back to the board. Then, as if testing me, he quickly wiped away the previous equation and replaced it with something significantly more complex.

"Alright, Hayatou," he said, regaining some of his composure. "That was impressive, but what about this problem?"

I glanced up at the new equation.

Quadratic functions, multiple variables, and a nested exponential?

I nearly sighed. Come on, Sensei… at least make it interesting.

Still, I straightened up and examined it fully, ensuring I didn't miss anything. A third-degree polynomial, with an embedded exponential decay function? Definitely a step up I guess... And an extra variable that seemed out of place—that's probably a trick meant to throw off less experienced students...

I traced the logic in my mind, watching as each step aligned perfectly into place.

"Alright..." I started, keeping my tone casual but respectful; "First, you'll need factor out the greatest common divisor to simplify the polynomial... Once that's done, you'll notice the remaining terms form a quadratic expression, which can be solved using either factoring or the quadratic formula. However, since the equation also contains an exponential term, you'd need to separate it and apply natural logarithms to neutralize the base. From there, you isolate the variable and solve accordingly."

I paused briefly before adding, "Though, Sensei, I think you might've made an error in writing it out. The coefficient on the second term doesn't quite fit the pattern—if you check your work, I believe it should be a negative constant instead of a positive one. Otherwise, the solution doesn't yield a real number."

The class fell into absolute silence.

I saw sensei's hand freeze midair. He turned back to the board, his gaze quickly scanning the equation. A moment passed. Then another.

Slowly, he exhaled. "You… are absolutely right."

I heard a few of the students gasp. Some of them weren't even finished copying the problem yet, and I had not only solved it but also corrected the teacher's mistake in real-time... Well, maybe in this aspect, I was probably ahead of Shikamaru, probably. Having an I.Q of 200 doesn't automatically mean it's geared towards math, not to say he's dumb at it, but the contrary...

Even then, if he practiced a bit on it, I'm sure he would be able surpass me given some level of effort. I doubt it would even take long either.

Still, I leaned back in my chair, resting my chin on my hand. Still bored...

-Sensei, if you want to keep testing me, you should probably pick something outside the academy curriculum.- Of course, I didn't actually say that out loud to him. Instead, I just gave a small nod. "I just happened to notice it."

The teacher looked at me for a long moment before sighing. "…Very well. That's beyond what I expected. Well done, Hayatou."

I simply nodded again, "It's not a problem sensei."

...

After the day continued, class was finally over. Plus, it isn't all that bad; Since I'm getting a little used to my current weights, I could walk a bit easier. I sat up, heading out to leave the classroom.

Just as I was about to leave, sensei stopped me, "Hayatou, I have good news for you... But, let's speak somewhere else for now. Follow me."

Hoh~ Looks Like I've won the lottery.

Toyo-sensei stood before me, arms crossed, a thoughtful look on his face. "I've spoken with the Hokage like you requested," he said, his voice steady, "and he says he wants to have a word with you."

I raised an eyebrow. Hmm? Didn't you just say you had good news? No… something about this felt off. His posture was relaxed, but there was an underlying stiffness in his tone. He's hiding something. Maybe this was even planned from the start—perhaps the Hokage had already taken an interest in me before Toyo even spoke to him. I wasn't naïve enough to believe my sudden display of skill hadn't raised even some flags...

Still… this was a good opportunity. Regardless of their reasoning, this meeting would let me take control of my next steps.

I kept my expression neutral and nodded. "Alright, I'll meet with him. Can we go now?"

Toyo sensei gave a small smile and gestured for me to follow; "Yes, of course."

With that, I was finally on my way to meet the Hokage himself—the man who held the fate of this village in his hands. This meeting… would determine how I moved forward.

And I intended to make sure it went exactly as I wanted.

I followed Toyo-sensei through the village, keeping my pace steady and my expression neutral. My mind, however, was already running through multiple possibilities.

What exactly does the Hokage want to talk about?

It wasn't hard to guess. My early graduation request, my rapid progress, and my fight against Kai had probably drawn far more attention than I originally intended. The real question was—did they see me as an asset? Or a problem?

Toyo-sensei led me to the Hokage's Office, a grand yet simple building sitting atop the village's administrative district. The guards at the entrance barely spared me a glance before stepping aside, allowing us to pass.

They were expecting me.

Interesting.

Toyo knocked twice on the large wooden doors before pushing them open. "Lord Hokage, I've brought Hayatou as requested."

I stepped inside.

Behind a well-organized desk sat Hiruzen Sarutobi, the Third Hokage. His presence wasn't overwhelming—not in the way a battlefield commander's would be—but there was a depth to him, an unshakable authority that radiated experience and wisdom.

His wrinkled face remained calm, his sharp eyes studying me in an unreadable manner. A faint wisp of smoke drifted from the pipe in his hand, curling into the air before disappearing.

For a moment, neither of us spoke.

Then, Hiruzen gestured to the chair in front of his desk. "Please, sit."

I obeyed without hesitation, keeping my posture relaxed but respectful. This was a delicate moment—I had to play this right.

The Hokage took another slow drag from his pipe before exhaling. "So… I hear you wish to graduate early."

I nodded. "Yes, Lord Hokage."

He tapped his fingers against the desk, his expression still unreadable. "I must say, it's not every day that an academy student requests such a thing. Nor is it every day that a student improves as rapidly as you have." His gaze sharpened slightly. "Toyo has spoken highly of your recent growth. But tell me, Hayatou… why do you want to graduate early?"

I met his gaze evenly. This was the test.

How much should I reveal?

Too much honesty, and I'd risk making them wary of me. Too little, and they wouldn't take me seriously. I needed to give just enough to keep them interested.

So I responded smoothly, "Because, I believe I'm ready..."

Of course, I would never tell him that it's due to my mother. That would be stupid way to go. Still, it wasn't inherently untrue. I truly do believe myself capable of the task. It was obvious. 

Hiruzen raised an eyebrow. "Is that so?"

"Yes," I continued, keeping my tone calm and measured. "The academy is no longer a place where I can grow... The material is too basic, the training is far too slow, and staying there would only waste time that could be spent honing my skills." I paused before adding, "I want to become stronger, and the academy no longer offers me that path."

Hiruzen studied me for a long moment. Then, he smiled slightly. "You remind me of another student I know… someone else who believed the academy was beneath him."

I already knew who he was talking about...

Itachi Uchiha. He was still alive, and the massacre hasn't happened yet either. Not like it's my concern anyway.

The comparison was… interesting. But I wasn't here to become some tragic prodigy like him—I was here to take control of my own path, survival and protection.

The Hokage exhaled, setting his pipe down. "Very well," he said. "I won't deny that your growth has been remarkable... But early graduation is not something I take lightly." His gaze hardened slightly. "The moment you leave the academy, you will no longer be a student—you will be a full fledged shinobi of Konoha. You will be expected to serve this village, to carry out dangerous missions, and to follow orders without hesitation."

I nodded. "I understand..."

Hiruzen leaned forward slightly. "Then prove it."

I kept my face neutral, "How?"

The Hokage smiled faintly. "A test. If you wish to graduate early, you must demonstrate your abilities in a real combat scenario... You will be evaluated not just on your strength, but on your skill, discipline, and ability to adapt under pressure."

I more than expected something like this.

"What are the conditions?" I asked.

Hiruzen glanced at Toyo-sensei. "You will face a Chuunin examiner in a sparring match. If you can prove that you are at least Genin-level in combat ability, you will be considered for early graduation."

"...Will this instructor have access to ninjutsu skills?"

Hiruzen gave me a small smile, "And what if they do?"

This sly old fox... He's definitely not making this easy... He'll probably bring in a veteran just to test me. If I fail, he likely wants it to be a learning experience for me, but if I pass, it'll confirm my prodigiousness. Quite a tight-rope situation...

"It won't be an issue lord third..."

Still, a Chuunin? Not an instructor. Not another student. A fully ranked shinobi. There was a difference to them. Chuunin instructors are not the same as their ranked shinobi counterpart in skills. There was a relatively large difference. Whether in illusionary, practical and strategical aspects...

I smirked slightly. Perfect.

"I accept them."

Hiruzen's eyes narrowed slightly, as if studying me one last time... Then, he gave a small nod. "Good. The test will be held in three days. Train well, Hayatou."

I stood up, bowing respectfully. "Thank you for the opportunity, Lord Hokage."

As I turned to leave, I needed to figure out a way to defeat my opponent

A Chūnin-level opponent, huh? With my current level, I could probably take one on easily. That was exactly what I needed...

As Hayatou exited the office, Toyo remained standing before the Hokage, his expression thoughtful. The conversation had gone as expected, but something about the boy still lingered in his mind.

"…What do you think of him, lord third?" Toyo finally asked, breaking the silence.

Hiruzen took a slow drag from his pipe, his sharp gaze fixed on the door that had just closed behind Hayatou. A faint wisp of smoke curled into the air as he exhaled, his mind turning over everything he had observed.

"He's certainly an enigma..." the Hokage admitted. "His growth is unnatural, his intelligence is well beyond his years, I could tell that from just a glance, and then some from just the way he spoke; and his confidence is… controlled." He paused for a moment before adding, "And that's what concerns me."

Toyo's brows furrowed. "Do you think he's dangerous?"

Hiruzen didn't respond immediately. Instead, he turned toward the window, his eyes sweeping over the vast expanse of Konoha. The village was peaceful, its people moving about their daily lives, unaware of the conversation taking place behind closed doors.

"…I don't know yet," he finally admitted, "But one thing is certain—he is definitely not an ordinary child."

A heavy silence settled in the room... Toyo crossed his arms, contemplating the implications of what this will even lead to.

"Then we'll see what he's really made of in three days..."

Hiruzen gave a slow nod, his expression unreadable. His fingers tapped idly against his desk, deep in thought.

"Yes," he mumbled, "I suppose we will."
