A Ninja Calamity is a Hufflepuff at Hogwarts

The Great Hall buzzed with morning energy as Hogwarts students gathered for their first official day of classes. The enchanted ceiling reflected a crisp autumn sky, the sunlight streaming in through the tall windows. Kouchi sat at the Hufflepuff table, his sharp eyes scanning the room with practiced ease. He wasn't expecting trouble—not yet—but old habits were hard to break.

His attention darted to the Gryffindor table, where Harry Potter sat, flanked by his friends. Potter seemed unaware of the many eyes watching him, including Kouchi's for a brief moment before he redirected his gaze elsewhere. He couldn't afford distractions, though keeping his senses sharp was second nature.

"Morning, Kouchi!"

The familiar voice of the Hufflepuff prefect, Cedric Diggory, broke through his thoughts. Cedric offered him a friendly smile as he placed a sheet of parchment in front of him. "Here's your timetable. First day, huh? You'll get the hang of it in no time."

Kouchi nodded silently, glancing down at the parchment. The schedule was packed from dawn till dusk. Double classes, study sessions, and even some "extra practice" blocks were penciled in. It left virtually no free time.

"Blimey, is that your timetable?" someone whispered nearby.

Several curious Hufflepuffs leaned over, craning their necks to get a better look.

"Is that… an Advanced Runes class?" asked a wide-eyed boy named Ernie Macmillan. "That's third-year material! Why do you have it?"

"Ancient Magical Theory, too?" added a girl with frizzy brown hair. "That's practically a N.E.W.T.-level subject!"

Kouchi shrugged indifferently. "It's what they assigned."

His dismissive tone only fueled the curiosity of his housemates. A few exchanged glances, whispering about how his course load seemed impossible. But Kouchi didn't care what they thought. He hadn't come to Hogwarts to relax; completing his mission and mastering any useful magical knowledge were his only priorities.

"Shouldn't you be...worried about burning out? wait! is this even allowed in the first place." a timid first-year asked cautiously.

Kouchi's gaze flicked to the boy, cool and unreadable. "I can handle it. Also, I passed tests for those classes, so it should be fine...I hope"

His blunt response silenced the group. They shuffled awkwardly back to their seats, still marveling at his seemingly impossible schedule.

Cedric chuckled, clapping Kouchi on the shoulder. "You've definitely got your work cut out for you, but if anyone can manage it, I'd bet it's you."

With that, Kouchi rose, grabbed his bag, and strode out of the Great Hall, heading for his first class—Charms.

The Charms classroom was warm and inviting, lined with shelves of ancient tomes and magical trinkets. Professor Flitwick, a diminutive wizard with an infectious enthusiasm for magic, stood on a stack of books behind his lectern, beaming at his students as they entered.

"Good morning, class!" he squeaked. "Today, we'll begin with the basics of wandwork and spell theory! A well-cast charm is more than just waving your wand—intent and focus are crucial!"

Kouchi settled into a seat near the back, scanning the room again out of habit. His classmates buzzed with excitement, wands at the ready.

"Today's spell: the Levitation Charm! Can anyone tell me the incantation?" Flitwick asked, his eyes twinkling.

Hermione Granger's hand shot up instantly. "Wingardium Leviosa!" she answered confidently.

"Excellent! Five points to Gryffindor!" Flitwick exclaimed. "Remember: swish and flick!"

Kouchi watched closely as Flitwick demonstrated the wand movement, the feathers on his desk floating gracefully into the air. His mind instantly made a comparison to ninja seal-making: the precision of hand signs, the necessity of controlling one's chakra flow, and the need for unwavering focus.

It's almost the same, he thought. But… different.

He observed the other students' attempts. Many struggled—either flicking too hard or mispronouncing the incantation entirely. Spells fizzled, feathers burst into flames, and one even shot across the room like a dart.

Kouchi frowned thoughtfully. He could see what they were doing wrong, but what intrigued him more was the strict structure of the spell itself. Everything was rigid—locked into specific words and gestures. It was unlike chakra manipulation, which thrived on adaptability and creative thinking.

"Alright, give it a try!" Flitwick encouraged.

Kouchi reluctantly pulled out his borrowed wand, feeling its unfamiliar weight in his hand. He repeated the motion exactly as Flitwick had demonstrated—swish and flick—but didn't speak the incantation aloud. Instead, he pushed a tiny pulse of chakra through the wand's core.

The feather on his desk shot into the air, hovering perfectly in place.

Several students gasped.

"Whoa! Did you see that?" whispered a Ravenclaw girl.

"Silent casting?" muttered another boy. "He didn't even say the spell!"

Flitwick, however, was more astonished than concerned. "Mr. Uchiha… that was exceptional control! Well done, ten points to Hufflepuff!" His tone was genuinely impressed, though his brow furrowed with curiosity.

Kouchi gave a polite nod but said nothing, keeping his expression carefully neutral. He had no intention of explaining how he'd bypassed the incantation entirely by channeling chakra instead of magical energy.

As the lesson continued, Kouchi grew more intrigued by the limitations he observed. Wizards seemed bound by rigid traditions—repeating the same ancient spells, relying on inherited knowledge without much thought toward innovation.

They're trapped in a box, he mused. Afraid to think beyond their traditions.

He wondered how much of that fear came from arrogance. Pure-blood wizards, especially, seemed stubbornly rooted in their ways. If they didn't understand something, they dismissed it. That narrow-mindedness was a weakness—one Kouchi could easily exploit if he ever needed to.

The bell rang, signaling the end of class. Students gathered their things, chattering excitedly about the lesson. As Kouchi packed his bag, Flitwick approached, still smiling warmly.

"Mr. Uchiha, a word, if you don't mind?"

Kouchi straightened. "Yes, Professor?"

"That spellwork you demonstrated was… remarkable. Your focus and precision are far beyond what I'd expect from a first-year."

"I practiced," Kouchi said simply.

Flitwick chuckled. "Practice indeed! I must say, I'm quite curious about your background. Have you studied magical theory before?"

Kouchi hesitated. "You could say that." 'Not that it was magic, but who cares.'

Flitwick regarded him thoughtfully but didn't press further. "Well, keep up the excellent work. I look forward to seeing what you accomplish."

With a polite nod, Kouchi left the classroom, his mind already turning over what he'd learned. Hogwarts might have been bound by outdated traditions, but there was power here—power he intended to understand, control, and, if necessary, use.
