Harem Training System: Every Girl I Train Makes Me Stronger!

The woman Ardyn inclined her head slightly toward Albert. The gesture was familiar, almost casual, the way one might acknowledge a subordinate who had done their job well.

"Headmaster... My apologies for the intrusion." Her voice was a low growl, resonant and carrying the authority of someone who had commanded thousands to death. "Word reached my unit about a student here who is demonstrating exceptional skill with a greatsword."

"Something was said to be considerably beyond the standard academy curriculum." Her eyes shifted, cutting through the darkness to lock onto William. "I wanted to see for myself whether the rumors held any truth or if they were merely the exaggerations of frightened instructors."

William felt his stomach lurch. His first instinct was to shield Lia, to pull her back into the shadows, but his body refused to obey.

He felt exposed, as if Ardyn’s gaze was a physical blade peeling back his skin to examine the bones beneath.

Beside him, Lia had gone deathly still.

Her inner mind was a frantic scramble of tactical assessments: ’Greatsword Corps... Elite... Commander Ardyn...’

’She’s not here for a visit... She’s here to assess. Wait, no... it’s more likely that she’s here to judge.’

"I’m sorry," William said, stepping forward, forcing himself to meet that glacial stare despite the primal urge to retreat. "But who exactly are you?"

Albert answered before Ardyn could, his voice dropping into a tone of solemnity that made the night feel even colder. "Ahh, Instructor Wade..."

"Forgive my bluntness, but allow me to introduce Commander Ardyn." He paused, the weight of her title hanging in the air like a guillotine blade. "Grand Greatswordmaster of the Royal Military."

"Commander of the elite Greatsword Corps... Her rank sits equal to Lady Seraphina’s own within her chosen discipline."

William froze. The implications crashed over him like an avalanche.

This wasn’t just a soldier. This was a living legend, a woman whose entire existence was defined by the brutal mastery of the very weapon she carried.

And she wasn’t here for diplomacy. She was here because he had drawn her attention.

William absorbed the revelation like a physical blow, a jolt of dawning, almost dizzying possibility that made his blood sing with both terror and opportunity.

He glanced sideways at Lia. Her pupils were dilated, her breathing shallow.

She wasn’t just surprised; she was reeling from the sheer magnitude of the power standing before them.

Her inner thoughts were a storm of panic: ’A Grand Greatswordmaster?’

’The woman who broke the Northern Siege alone?’

’If she sees me... if she sees how broken my technique still is... she won’t just dismiss me.’

’She’ll destroy what’s left of my spirit.’

William knew he couldn’t let that fear paralyze her. He had to seize this moment, to turn this terrifying intrusion into a lifeline.

"Commander," William said, his voice cutting through the tense silence.

He stepped forward, his movements deliberate and charged with an urgent, desperate purpose that forced Albert to blink in surprise. "I think you might be exactly what we need right now."

Ardyn arched a single, dark eyebrow. The movement was minimal, but it carried the weight of a challenge.

Her eyes narrowed, studying him as if deciding whether to reward his audacity or crush it. "Ohh...?"

"Is that so, Instructor?" she asked, her voice dripping with a dangerous curiosity. "And what exactly could a military commander provide to an academic institution that your curriculum cannot?"

"This is Lia Valestria," William continued, gesturing toward the girl beside him. "My focus student, whom I am training right now."

Lia stiffened, her jaw locking as she stepped into the light. "The student whose work has reached your ears."

"She is currently facing a formal evaluation from her family, an assessment that will determine whether she is entitled to remain at this academy or if she will be cast out to fulfill some predetermined fate."

He saw Ardyn’s gaze shift to Lia, sharp as a scalpel. "I’d like to propose something, Commander."

"A wager of skill rather than politics... Let her fight you."

"But I wanted this to be not a sparring match nor a controlled demonstration, but a real test." William clenched his fists. "Against someone whose mastery of the greatsword is beyond question and even beyond mortal doubt."

William’s heart hammered against his ribs. He could feel Lia’s shock radiating off her like heat.

"If she can hold her own against a Grand Greatswordmaster and if she can survive even ten minutes against your steel, then that is proof no Valestria council could reasonably dismiss. It would be an undeniable testament to her worth."

A heavy silence descended. The soldiers behind Ardyn remained motionless, statues of iron and shadow.

Ardyn studied Lia with renewed interest, her gaze sweeping over the girl’s frame with the same calculating, ruthless attention William recognized from his own years of assessing whether a recruit was worth the rations they consumed.

She wasn’t looking at Lia’s face; she was looking at her stance, the calluses on her hands, and the way her weight was distributed.

"Bold proposal, Instructor," Ardyn said slowly, the words rolling like distant thunder. "Very bold indeed..."

"But what’s the catch? Why would I waste my time playing judge for a family squabble?"

"Because you’re a warrior," William countered, meeting her flinty eyes without flinching. "And because you know that true talent is rare."

"With all my respects and apologies... I need one more week." He leaned in slightly, his voice dropping to a tone of fierce conviction. "Seven days to train her properly."

"To forge her technique into something that can actually withstand your pressure."

"I won’t put her in front of you unprepared... I won’t offer you a puppet show."

"Give me seven days of hell, and then let her prove herself honestly."

Lia’s mind whirled. ’Seven days?’

’Seven days to prepare to fight a god of war?’

’He’s asking me to walk into the furnace.’ But beneath the terror, a spark of something else ignited a desperate, burning hope. ’If I win... if I even survive... I’ll finally be real.’

Ardyn simply studied him for what felt like an eternity. The tension was so thick it felt as though the air might fracture.

Then, something unexpected happened: something amused flickered behind those glacial eyes. A slow, genuine grin spread across her scarred face, a grin that was both terrifying and strangely approving.

"I like your nerve, Instructor Wade," Ardyn said, her laugh a low, gravelly sound that echoed off the academy walls. "Most men would be stammering apologies for wasting my time."

"You’re asking me to witness a potential legend." She turned her gaze back to Lia, her eyes gleaming with the hunger of a predator who had found a worthy prey. "Very well."

"One week... I can deal with that."

"Seven days to sharpen that blade of yours, girl." Ardyn smiled at her. "Because when I come back, I won’t be holding anything back."

"I’ll come to see if you’re a Valestria... or if you’re just another broken child playing with steel."

Lia turned to William, her face pale beneath the moonlight, her expression a raw collision of shock, disbelief, and a fragile, terrifying hope that seemed to tremble in her very bones.

Her eyes searched his, desperate for some sign that this wasn’t another cruel trick of fate, another false promise before the inevitable fall.

William met her gaze head-on. He didn’t offer false platitudes or empty comfort; instead, he let a confident, almost defiant grin spread across his face.

He gave her a quick, reassuring thumbs up, a small, human gesture that felt impossibly grounding amidst the gathering storm of Ardyn’s presence.

"See?" he said, his voice low but carrying an unshakable certainty that acted like an anchor for her spiraling thoughts. "I told you something would work out."

"We’re not done yet."

Lia’s inner voice was a cacophony of noise. ’Seven days... Seven days to learn how to survive a monster...’

’He believes in me... Why does he believe in me when I can barely believe in myself?’ But beneath the panic, the spark Ardyn had inadvertently ignited began to glow hotter.

For the first time in her life, she wasn’t being told what she was; she was being given the chance to prove it.

Headmaster Albert stepped forward then, breaking the charged silence between them. His face had lost its flustered concern, replaced by the sharp, calculating focus of an administrator who had just seen a dangerous game begin.

"I will handle the formal arrangements immediately," he said, his tone decisive. "I’ll send an urgent missive to Lady Seraphina."

"I’ll frame it as an unprecedented opportunity for her sister—a chance to test her mettle against the Royal Greatsword Corps."

"That should provide sufficient political cover for her family to permit this extension." He glanced at Ardyn’s departing column of steel, then back to William. "Leave the politics to me..."

"You focus on the girl."

A wave of relief so profound it felt physical washed over William, threatening to buckle his knees. He wanted to laugh, to shout at the sky, to vent the pent-up adrenaline that had been coiled in his gut since Ardyn first appeared.

Beside him, Lia let out a long, shuddering breath, a sound that was half sob and half exhale as the crushing tension of the past week finally began to bleed out of her shoulders.

The night stretched on, the air growing colder as the adrenaline ebbed away, leaving behind a hollow exhaustion.

By the time the last of Ardyn’s soldiers had vanished into the dormitory wings and the courtyard had returned to its haunted silence, the moon had climbed to its zenith.

The academy felt different now, less like a school and more like a training ground for something far more brutal.
