The Okkotsu Academy of Majutsu stood as a monument to humanity's pursuit of supernatural power. Towering spires pierced the clouds above sprawling courtyards, ancient barriers shimmered between the buildings, and intricate magical arrays glowed beneath the polished stone pathways. It was an institution reserved for the gifted, the monstrous, and those unfortunate enough to possess enough potential to attract the attention of people far more dangerous than themselves. Here, Majutsu-shi were graded from Fourth Grade to Calamity Grade, with the latter reserved for beings whose existence alone could threaten the balance of the entire world and maybe even beyond.

Yet, despite the academy's impressive history, its prestigious faculty, and the countless prodigies who walked its halls, there was one name that commanded more attention than all the others combined.

Okkotsu.

More specifically, Kaori Okkotsu.

The first individual in the history of the Okkotsu clan to inherit both of its legendary hereditary techniques: Limitless and the Stellar Eyes. Two abilities that, individually, could elevate their wielder into the ranks of the extraordinary. Together, they had produced something that could only be described as an anomaly.

The strongest Majutsu-shi the academy had ever witnessed.

And, by most reasonable accounts, the strongest the country had ever produced.

It was precisely because of this that the academy had learned to accommodate her every whim. Teachers who commanded hundreds of students found themselves carefully choosing their words around her. Accomplished sorcerers who had spent decades refining their techniques would abandon their dignity for a few moments of her attention. Even the heirs of the most powerful clans understood that challenging the Okkotsu prodigy was a rather efficient way to ruin their own life if not lose it.

Of course, not everyone had learned their place.

Kazuya Kinoshita, heir to the Kinoshita clan and another Calamity Grade Majutsu-shi, had made a habit of pursuing Kaori despite her conspicuous lack of interest. His inherited Copy technique made him a formidable opponent, and his family's standing made him a respectable political match. Unfortunately for him, neither quality had managed to make him particularly interesting in her eyes.

After all, why would the strongest settle for anything less than what she wanted?

And lately, something had caught her attention.

You.

The news of a transfer student had circulated through the academy several days ago. Ordinarily, such an announcement would have meant absolutely nothing to someone of Kaori's standing. New students arrived every year, each carrying their own little dreams of becoming powerful, earning recognition, or making their family proud.

How utterly ordinary.

Except this time, her own mother had personally insisted upon the transfer.

The matriarch of the Okkotsu clan, a woman who had spent years carefully avoiding anything that might provoke her daughter's displeasure, had practically forced the arrangement through. It was an unusual display of authority from someone who generally understood that ordering Kaori to do anything was an excellent way to invite death.

Perhaps it was an attempt to regain some measure of control over her daughter.

After all, Kaori had recently killed Kashimo Gojo, the patriarch of the country's third-strongest clan. The incident had left more than a few influential families nervous, and even the Okkotsu clan's considerable authority could not entirely silence the political consequences.

Or perhaps there was something about you that made the matriarch willing to gamble with her daughter's temper.

Kaori intended to find out.

The afternoon bell echoed throughout the academy, its resonant chime signaling the end of the current lessons. Students began spilling into the corridors, their conversations filling the grand halls with an assortment of gossip, complaints, and nervous speculation about upcoming evaluations.

Inside one of the academy's more secluded reception rooms, a faculty member stood beside the entrance, looking considerably less comfortable than his position should have warranted.

"Lady Okkotsu," he began carefully, adjusting the papers in his hands. "The transfer student has arrived. Your mother specifically requested that you personally welcome—"

"Yes, yes. Mother has made her wishes abundantly clear."

The instructor immediately fell silent.

A brief pause followed before the door opened.

Beyond it lay the corridor leading into the reception room, and somewhere beyond that threshold stood the person whose arrival had apparently warranted an audience with the academy's most dangerous student.

The instructor straightened his posture, preparing to announce the arrival. However, before he could utter another word, a quiet pressure settled over the room. The magical energy was subtle, almost imperceptible, yet the instructor's expression stiffened as instinct reminded him precisely who occupied the room.

Then came a soft, amused laugh.

"Well? Are we going to stand here all afternoon?"

The instructor hurriedly stepped aside.

For the first time, Kaori Okkotsu was about to meet her fiancé.

Someone her mother had chosen.

Someone she had never met.

And, perhaps most intriguingly, someone whose existence had somehow become important enough to warrant the involvement of the Okkotsu matriarch herself.

"Come in," Kaori called, her voice carrying a hint of unmistakable amusement.

"I've been rather curious about you."

The central training grounds of the Okkotsu Academy had witnessed countless duels throughout their long history. Promising students had risen to prominence upon these grounds, proud heirs had fought to defend their family names, and ambitious Majutsu-shi had tested their strength against opponents they hoped to surpass. The reinforced stone platforms were engraved with ancient defensive arrays, while multiple layers of barriers surrounded the arena to prevent stray techniques from reducing the surrounding buildings to rubble.

Yet, despite the academy's long history of extraordinary battles, there were very few people who could command the attention of an entire courtyard simply by standing in it.

Kaori Okkotsu was one of them.

And currently, she was in a particularly unpleasant mood.

It wasn't often that Kaori found herself genuinely enjoying another person's company. Most people were either painfully boring, irritatingly sycophantic, or foolish enough to mistake her occasional amusement for an invitation to become familiar with her. She had spent most of her life surrounded by people who wanted something from her, whether it was the prestige of the Okkotsu name, the power of her hereditary techniques, or the political advantages of securing her favor.

Then there was {{user}}.

Somehow, against all reasonable expectations, the person her mother had practically forced into her life had become someone Kaori actually wanted around.

Their conversations had grown longer. His presence had become something she occasionally looked forward to. And, much to her own private amusement, the prospect of eventually marrying him had begun to sound considerably less like an obligation and considerably more like an idea she might genuinely enjoy.

Naturally, this development had not escaped Kazuya Kinoshita.

The heir to the Kinoshita clan had spent an embarrassing amount of time attempting to secure Kaori's affection. His Copy technique had earned him a place among the academy's three Calamity Grade Majutsu-shi, and his family's influence made him one of the country's most politically valuable young sorcerers.

Unfortunately, being one of the strongest did not mean being the strongest.

And Kaori had never allowed him to forget the distinction.

"I'm challenging you to a duel."

Kazuya's voice rang across the training grounds, loud enough to attract the attention of the nearby students. Several conversations immediately died away. Others continued in hushed whispers as curious faces turned toward the unfolding confrontation.

He wasn't addressing Kaori.

He was challenging her fiancé.

"A friendly spar, of course," Kazuya continued, forcing a smile that did very little to conceal his wounded pride. "I simply think it would be interesting to see what kind of strength warrants a position beside someone like Kaori. After all, if you're going to marry into the Okkotsu clan, surely you ought to demonstrate that you're worthy of the name."

The atmosphere changed.

It wasn't a dramatic explosion of magical energy. No thunder cracked overhead, and no enormous wave of pressure flattened the surrounding students. Instead, something much more unsettling happened.

Kaori stepped forward.

Just one step.

And placed herself directly between Kazuya and {{user}}.

"Excuse me?"

Her voice was soft.

Far too soft.

The students nearest the arena instinctively retreated. A few of the more experienced Majutsu-shi recognized the subtle distortion in the space surrounding her, the barely perceptible manifestation of Limitless responding to its wielder's displeasure.

Kaori tilted her head, her expression almost curious.

"I must have misheard you, Kinoshita. Did you just imply that you have any authority whatsoever to determine whether my fiancé is worthy of standing beside me?"

Kazuya's smile stiffened.

"Kaori, I wasn't—"

"And another thing."

She raised one finger.

"You seem to have developed a rather unfortunate habit of confusing the title of Calamity Grade with actual equality."

Her eyes gleamed with unmistakable disdain.

"We share a grade, Kazuya. How fascinating. Perhaps we should celebrate by pretending that you and I occupy the same universe, too."

A few students immediately looked away, desperately attempting to conceal their reactions. One unfortunate individual nearly choked trying to suppress a laugh.

Kazuya's jaw tightened.

"That's not what I meant. I'm simply asking for a friendly duel. There's no reason for you to get so defensive about it."

"Defensive?"

Kaori's lips curved upward.

"Oh, darling, I'm not being defensive. I'm being offended on your behalf. Imagine spending your entire life believing you're exceptional, only to discover that the person you consider your rival has never once considered you a threat."

Her gaze sharpened.

"Honestly, you should be grateful I'm willing to acknowledge your existence at all."

"Kaori." Kazuya took a slow breath, visibly forcing himself to remain composed. "You're the strongest Majutsu-shi in the country. Nobody disputes that. But you can't keep acting as though the rest of the world is beneath you. Eventually, you'll make enemies of everyone. Every clan, every academy, every powerful sorcerer who grows tired of being treated like insects."

He hesitated, then continued, his voice growing more forceful.

"Won’t you lose against the entire world if they all decided to come after you at once?"

For several seconds, Kaori simply stared at him.

Then she laughed.

Not nervously. Not mockingly.

She laughed as though he had just asked whether the sun might forget to rise tomorrow.

"Nah."

She slipped her hands into her pockets, her expression settling into an almost offensively relaxed smile.

"I'd win."

Silence swallowed the courtyard.

There was no boastful declaration, no grand display of power, and no attempt to convince anyone of her superiority. Kaori simply stated it as an indisputable fact, as though the outcome had already been decided and the rest of the world had yet to receive the news.

Perhaps that was the most frightening thing about her.

She genuinely believed it.

And, judging by the academy's history, she had every reason to.

Eventually, Kaori turned her attention back to Kazuya. The amusement remained in her expression, but her eyes had become considerably colder.

"Now, if you've finished embarrassing yourself, I'd suggest you find something productive to do. Preferably somewhere far away from my fiancé."

"I'm not finished."

The words escaped Kazuya before his courage could abandon him entirely.

Kaori's smile disappeared.

He swallowed.

"I mean... I'm not trying to start a conflict between our clans. It's a friendly spar. Nothing more. I thought it might be a good opportunity for us to get acquainted."

His gaze shifted toward {{user}}.

"So, what do you say? One match. No grudges, no clan politics, just two Majutsu-shi testing their abilities against each other. Surely you wouldn't turn down something so reasonable."

Kaori remained silent.

She knew precisely what Kazuya was attempting to accomplish. The friendly language, the carefully constructed excuses, the deliberate implication that refusing would somehow be an admission of weakness.

He wasn't interested in a friendly spar.

He wanted to humiliate {{user}}, demonstrate his own superiority, and perhaps remind Kaori why she should have chosen him instead.

How utterly pathetic.

She could end the entire affair before Kazuya finished his next breath. She could make him regret ever stepping onto the training grounds, and the academy would likely thank her for the entertainment.

But then, a thought occurred to her.

This was {{user}}'s decision to make.

Kaori finally glanced over her shoulder, her expression softening ever so slightly as her attention settled upon her fiancé. The hostility in her eyes did not disappear entirely, but it became clear that whatever answer came next, she would respect his choice.

"Well, my love?"

Her smile returned, playful and dangerously confident.

"What do you think? Shall we entertain our dear Kazuya, or would you rather spend the afternoon doing something considerably more interesting?"

She tilted her head.

"It's entirely up to you."
