The battlefield was drenched in rising steam, a thick fog rolling across the Academy's training grounds. Bernard's latest spell had flooded the area with water, rapidly cooling Shinjuu's steel body after withstanding Bernard's earlier fire attack. The contrast in temperatures had created this dense mist, obscuring visibility and transforming the training field into an otherworldly landscape.

  Shinjuu gritted his teeth as the fog thickened around him, the sound of metal grinding against metal. His steel-coated eyes strained to pierce the white veil surrounding him. "Damn it... I can't see the brat anymore." His head turned slowly, methodically scanning the misty battlefield. "That Bernard... he's not just strong, he's calculated."

  Then—

  A hand clamped down on his shoulder.

  Shinjuu's body locked up in shock, steel plates shifting defensively even as he recognized he'd been caught completely unaware.

  "I win, teacher," Bernard's voice whispered calmly from behind him. "This was a good exhibition."

  Shinjuu blinked, stunned by the sudden defeat. "How...?"

  The mist around them slowly began to clear, tendrils of vapor parting to reveal Bernard standing tall, his hand resting lightly on Shinjuu's steel-coated shoulder. His grimoire floated beside him, its pages flipping gently in the breeze, ancient symbols glowing faintly along its edges.

  Shinjuu turned toward it, his eyes narrowing at the current page displayed in the floating book:

  Acceleration.

  "You were too focused on surviving the initial elements," Bernard explained, his voice carrying the precise tone of a teacher rather than a student. "Your body went from extreme heat to extreme cooling in a short span of time. It forced your actual body into shock, meaning you instinctively kept your steel state active to protect yourself."

  Shinjuu clenched his fist, still feeling the lingering effects of the sudden shifts in temperature. His steel coating had protected him from burns and frostbite, but had also trapped him in a pattern Bernard had anticipated.

  "And here's the kicker," Bernard continued, flipping the grimoire forward slightly to show the next page of spells. "Had I cast my Acceleration spell, it would have sped up the rusting process on your steel body—thus killing you."

  A heavy silence filled the air.

  What went unspoken hung between them—Bernard had purposely stopped short of a lethal attack, but he had demonstrated that he could have delivered one. It wasn't just a victory; it was a masterclass in strategic combat.

  Shinjuu exhaled sharply, then let out a deep chuckle. He slowly dropped his combat stance, the steel plates of his face shifting to reveal a genuine smile as he acknowledged Bernard's wit. "Tch... I guess I underestimated you."

  The training grounds echoed with the aftermath of Bernard's victory over Shinjuu. Steam still curled through the air, dissipating slowly as the two combatants faced each other with newfound respect. Bernard's grimoire floated beside him, its pages settling back to a gentle flutter after the intensity of battle.

  Shinjuu's steel-coated body gleamed under the morning sun as he rolled his shoulders, metal plates shifting smoothly back into their resting position. "Not bad," he acknowledged, genuine admiration in his voice. "You've got strategy behind that power of yours."

  Bernard nodded once, the gesture precise and economical like everything else about him. "Strategy is what separates concepts from mere abilities," he replied, closing his grimoire with a gesture. The book dissolved into motes of light that disappeared into the air.

  Across the training ground, Josuke was still in perpetual retreat, desperately dodging Mya's enchanted perfume mists. His face flushed with exertion, sweat pouring down his forehead as he kept just ahead of the pursuing pink clouds.

  "You're just delaying the inevitable, pretty boy~" Mya sang out, twirling another ornate bottle between her fingers. The glass caught the sunlight, sending prisms of color dancing across the ground. "One little breath, and you'll be mine."

  Josuke skidded to a halt, panting heavily. "I can't keep this up forever," he gasped, hands on his knees. "There's gotta be some way to..."

  Stolen from Royal Road, this story should be reported if encountered on Amazon.

  Bernard approached them, his measured steps interrupting their chase. Mya paused her assault, lowering her perfume bottle with a curious tilt of her head. Josuke straightened, relieved for the momentary reprieve.

  "Josuke," Bernard said, his voice carrying that quiet authority that made everyone listen. "Have you ever tried Mana Refinement?"

  The question hung in the air, unexpected and perplexing. Josuke blinked, confusion written plainly across his sweat-streaked face. "Mana... what?"

  Bernard gestured for Josuke to sit on a nearby stone bench. After a moment's hesitation, Josuke complied, still keeping a wary eye on Mya who had strolled over to join them, intrigued by the sudden shift in training.

  "Every sorcerer has two fundamental aspects to their power," Bernard began, sitting beside Josuke. He raised his hand, palm up, and a small orb of light appeared, hovering just above his skin. "First, there's mana—the raw energy that powers all abilities."

  The orb shifted, transforming into a miniature representation of a die—Bernard's signature item. "Second, there's your concept—the unique manifestation of that energy that defines your abilities."

  Josuke leaned forward despite himself, genuinely curious. "So... mine is temperature control?"

  Bernard nodded. "Exactly. But most sorcerers make a critical mistake—they focus exclusively on developing their concept while neglecting the underlying mana that powers it."

  Mya slid onto the bench on Josuke's other side, her usual flirtatious demeanor softening into something more sincere. "It's like building a house with a weak foundation," she added, surprising both men with her insight. "No matter how pretty the exterior, it'll collapse under pressure."

  Bernard gave her an appreciative nod. "Well put. Mana Refinement is the process of strengthening that foundation. Rather than constantly pushing the limits of your concept, you focus inward—making your mana more efficient, more responsive, more powerful."

  Josuke frowned, struggling to understand. "But... how does that help me in a fight? Being able to change temperatures a little better doesn't seem that useful."

  "Let me demonstrate," Mya offered, rising gracefully from the bench. She walked to a small pond at the edge of the training ground, beckoning for the others to follow.

  "My concept is infatuation," she explained as they gathered around the water. "At its most basic level, it allows me to create potions that temporarily influence emotions—make others feel attraction, devotion, obsession." She rolled her eyes playfully. "Most men assume it's only good for making them fall in love with me."

  "But it's not?" Josuke asked, genuinely curious now.

  "Watch."

  Mya knelt beside the pond and dipped her fingers into the water. Her eyes closed in concentration, and a soft pink glow emanated from her hand, spreading through the water in delicate tendrils.

  "I used to need physical ingredients—flowers, herbs, essences—to create my potions," she explained, her voice taking on a teacher's cadence. "And they required direct contact to affect someone."

  As they watched, the water beneath her fingers began to change, shifting from clear to a shimmering pink liquid that seemed to move with purpose, curling around her fingers like an affectionate cat.

  "But after I refined my mana, I discovered I could transform ordinary substances into potions directly." She lifted her hand, and a perfect sphere of the pink liquid rose from the pond, hovering in the air. "Water into wonder."

  Bernard picked up the explanation. "Mana Refinement opened new possibilities for her concept. Instead of just creating something that makes people infatuated with her—"

  "I can make objects infatuated with me," Mya finished, her smile widening as the liquid sphere began to orbit around her. "Water follows my commands because it's literally devoted to me."

  To demonstrate, she gestured toward a training dummy several yards away, and the liquid shot forward, wrapping around the dummy's arms and legs like restraints.

  "Containment, not just confusion," Bernard noted. "A significant expansion of her concept's application."

  Josuke stared, mouth slightly agape. "That's... actually incredible."

  Bernard turned to him, eyes serious. "Your temperature manipulation could be just as versatile. Imagine not just heating or cooling objects, but controlling the very flow of thermal energy. Creating heat shields, flash-freezing projectiles, perhaps even something approaching temperature telekinesis—moving objects by manipulating the heat differentials within them."

  "I could do that?" Josuke asked, voice barely above a whisper.

  "With proper Mana Refinement, maybe. The question is, are you willing to do the work? It's not as flashy as concept training. It's internal, methodical, sometimes tedious."

  Josuke looked at his own hands, then at Mya's liquid creation, then at Bernard's calm, expectant face. For perhaps the first time since joining the Academy, a genuine determination replaced his usual nervous hesitation.

  "How do I start?"

  Bernard smiled, a rare expression that transformed his scholarly features. "Meditation. Mana circulation exercises. Controlled application under increasing pressure."

  Mya released her hold on the water, letting it splash back into the pond. "It's brutally difficult at first," she admitted. "I cried for three days straight when I started."

  "But worth it?" Josuke asked.

  She winked. "Would I be this amazing if it wasn't?"

  From across the training ground, Shinjuu watched the interaction with crossed arms, a thoughtful expression on his steel-coated face. Something unexpected was happening—Bernard had naturally taken on the role of team strategist and mentor, Mya had revealed depths beyond her flirtatious facade, and Josuke...

  Josuke was actually listening. Not running, not deflecting with humor, not looking for the easiest path—but genuinely engaging with the challenge before him.

  Pride swelled in Shinjuu's chest, an unfamiliar but not unwelcome sensation. When Haikito had assigned him this team, he'd viewed it as a demotion, a burden to be carried. These kids were untested, undisciplined, their potentials unrealized.

  But now, watching Bernard naturally guide his teammates, seeing Mya share her experience with sincerity, observing Josuke's newfound determination—Shinjuu realized Haikito had given him something precious: not just students, but future heroes with the capacity for greatness.

  As the morning training session concluded and his team gathered their things, Shinjuu called out, "Same time tomorrow. Bernard, bring materials on Mana Refinement basics. We're adjusting our training regimen."

  Bernard nodded, that small smile still playing at the corners of his mouth.

  Josuke didn't groan as expected. Instead, he asked, "Is there anything I should do to prepare?"

  "Get rest," Shinjuu advised, surprised but pleased by the question. "What comes next will push you to your limits."

  As the team departed, Shinjuu remained behind, watching them walk toward the Academy building. Their silhouettes against the morning sun formed a tableau that struck him as significant somehow—three distinct personalities moving in unison, falling naturally into step with one another.

  Tomorrow would bring new challenges, new struggles, new growth. For now, though, Shinjuu allowed himself a moment of satisfaction.

  Perhaps there was something to this teaching business after all.
