The rhythmic thud of the old wooden floorboards echoed his every step, a predictable, comforting cadence. *Left, right, left, right.* Daan made sure each footfall landed with the same pressure, the same slight drag of his worn sneakers. It was a habit born of necessity, a subconscious audit of his own physical precision. He’d probably done it for so long, he’d forgotten how to walk any other way. The corridor, however, was anything but comforting. It hadn’t changed in the decade since he’d dropped out, still smelling faintly of old paper and dust motes dancing in the weak sunlight filtering through the grimy windows. Institutional, bleak, and utterly uninspiring. Not that he expected much from Jujutsu High, a place that excelled at producing high-grade trauma.
He paused at the door marked "Classroom 1-A," adjusting the strap of his oversized messenger bag. The irony of being back in a classroom, let alone teaching one, wasn’t lost on him. He, Daan, the dropout whose special-grade designation had lasted three weeks before he’d decided formalized jujutsu sorcery was a waste of perfectly good manipulation, was now supposed to impart wisdom. He snorted. Well, he’d certainly impart *something*. Gojo had assured him it would be "fun." Gojo had also assured him that the "temporary administrative leave" of his last two assistants was purely coincidental to Daan's... unconventional methods. Daan didn't believe Gojo for a second. Gojo thought chaos was fun. Daan saw chaos as an inefficient, unmanaged variable, and he hated inefficiency more than he hated weak coffee. He *really* hated weak coffee.
He pushed the door open without knocking. Inside, three students were already present, clustered around a desk. A towering figure in black, impossibly pale hair framing a blindfolded face, draped himself over a student's chair, impossibly long legs stretched out. Gojo Satoru. Of course.
“Daan! My favorite prodigal son, back from the corporate wilderness!” Gojo’s voice was as saccharine as it was loud. He clapped Daan on the shoulder, a little too hard.
Daan merely raised an eyebrow, ignoring the physical contact. He made a mental note: *Gojo, too much enthusiasm.* "Satoru. Still harassing children, I see." He scanned the room, his gaze lingering briefly on each of the students.
The pink-haired one, Itadori Yuuji, looked up, a bright, guileless smile on his face. “Sensei? Are you the new teacher everyone’s talking about?” His cursed energy, while noticeable, still felt… unrefined. Like a boundless, enthusiastic puppy whose owner hadn’t quite figured out how to house-train it.
"I am Daan," he stated. His eyes flickered to the black-haired boy with spiky hair, Fushiguro Megumi, who offered a curt nod, his expression guarded. Megumi’s cursed energy was like a coiled spring, held tight, barely revealing anything. Good. “And yes, for the next—semester, I suppose—I’ll be your… instructor.” He made the word sound vaguely distasteful. “Now, before we begin, I understand there are… certain parameters to our arrangement.” His eyes narrowed at Gojo.
Gojo chuckled, pulling a lollipop from seemingly nowhere and unwrapping it with a flourish. "Ah, yes! The no-technique clause. Understandable, given your *unique* abilities, Daan. For the safety and… continued sanity of my adorable students, we’ve agreed you won’t be actively using your Cursed Technique during lessons. Just stick to the curriculum, alright? No mind-bending manipulations, no covert takeovers of student wills. Promise?"
The pink-haired girl, Kugisaki Nobara, who had been painting her nails an aggressive shade of crimson, looked up, a spark of annoyance in her eyes. "Wait, 'mind-bending manipulations'? What kind of Cursed Technique does he have?"
Daan deliberately took a step back, aligning his feet perfectly. Then, he took another step back, landing in the exact same spot, his left foot meeting the worn wood with precisely the same pressure. He caught Nobara's eye. Her gaze sharpened, processing the repetition. He saw the faint, almost imperceptible flicker in her cursed energy, the momentary internal recalibration that indicated the connection had attempted to form. It failed, of course; he hadn't intended for it to succeed, nor was he activating it. It was a test. A demonstration. A reminder. *They need to know.*
"It's called Scentless Apprentice," Daan said, his voice flat. "And unlike most techniques, you wouldn't even know it was happening until it was too late. Lucky for you, I've agreed not to 'actively use' it. Which means," he held up a finger, then two—identical, precise movements, "no making you think you want to do my chores during class time. No subtly convincing you to write my reports. And absolutely no suggesting you'd enjoy a nice, long, voluntary hike into a grade 3 curse den for… research." He watched Gojo, a wry twist to his lips. "It's a very strict definition of 'not actively using,' as you might imagine."
Nobara blinked, a shiver running down her spine. "That's... creepy."
Yuuji frowned. "But if he’s not using his technique, what's he supposed to teach us?" He looked genuinely confused, his innocent optimism almost painful to witness.
Daan sighed. "Strategic thinking. Tactical deployment. Situational awareness. The kind of things that keep you from getting killed by something you didn't even realize was there." He walked over to the whiteboard, picked up a marker, and with a series of quick, identical wrist flicks, uncapped it. He made sure to hold Nobara's gaze again. She visibly tensed, a flicker of something close to paranoia in her eyes. Good. His point was made.
He turned to the board. "Consider this scenario: you're tracking a curse. It's subtle, elusive. You know it exists, but you can't pin it down. What's the first thing you assess?"
Megumi, ever the pragmatist, spoke without hesitation. "Its domain. If it has one, that's the primary threat."
Daan nodded slowly. "Good. But what if it doesn't? What if it operates entirely outside of conventional jujutsu parameters? Something that feeds not on fear, but on… complacency. On the mundane. What then?" He drew a complex, interconnected web on the whiteboard. "Every action has a ripple. Every decision, a consequence. You are not fighting isolated entities; you are fighting systems of influence. And understanding those systems is far more potent than any cursed technique." He glanced back at Gojo. "Even mine."
Gojo, having finished his lollipop, tossed the stick into a nearby wastebasket with unnatural precision. "He's a very clever man, our Daan. And a master of… unconventional persuasion. Listen to him, kids. He knows things." Even Gojo's casual endorsement felt like a veiled warning. He wasn't explaining *why* Daan knew these things, or *how* he had acquired such a comprehensive understanding of "systems of influence." There was always something Gojo left unsaid, a deliberate omission that hinted at deeper currents.
Daan ignored him, turning back to the students. "Alright. Hypothetical. You find a series of seemingly unrelated incidents. A district leader suddenly re-routes funding from a critical ward to a new, unnecessary construction project. A restaurant owner, previously known for impeccable hygiene, suddenly implements a new, utterly baffling, unsanitary standard. A minor grade 3 curse, completely out of its depth, manages to escape a high-security holding cell, despite no apparent breach." He tapped the whiteboard with the marker, another precise double tap. "What connects them?"
Yuuji scratched his head. "Uh… coincidences?"
Nobara scoffed. "There are no coincidences in jujutsu."
"Precisely, Kugisaki," Daan affirmed. "Now, what kind of curse, or indeed, what kind of sorcerer, benefits from such… disparate, yet consistently flawed, outcomes?"
Megumi narrowed his eyes, a glint of genuine curiosity replacing his usual caution. "A psychological one? Something that twists intent, rather than physically attacking?"
Daan smirked. "Getting warmer, Fushiguro. But how would it do so without leaving a trace? Without
anyone noticing the strings? Consider the implications not just for the victims, but for *you*, as sorcerers. How do you fight something you cannot see, cannot sense, cannot even comprehend without first doubting your own mind?" He took a measured step away from the board, then another, identical to the first. *Left, right, left, right.* Nobara flinched. Yuuji looked bewildered. Megumi was thinking, truly thinking, a rare sight.
He had promised Gojo he wouldn't use his technique. But he hadn't promised not to make them *feel* it. The best way to understand a phantom limb was to be reminded, acutely, of where the limb once was. And these children, they needed to feel the chill of a puppet master, even if the strings remained invisible. Gojo thought this was a game. Daan knew it was a lesson, paid for in paranoia.
