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

The remainder of the morning dissolved into a frantic, disorganized haze of preparation, a process that, true to form, produced its own steady stream of escalating chaos.

Kaela arrived at the equipment shed looking less like a student heading to a dungeon and more like a mercenary captain preparing to storm a fortress. She had what could generously be called an alarming amount of backup weaponry strapped across her back, her shoulders straining under the weight.

There were three separate practice swords, a dagger at her hip, and what appeared to be a small hand axe strapped to her thigh, an implement of dubious training relevance that screamed ’panic buying.’

William stared at her, rubbing the bridge of his nose.

"Kaela, you do realize we’re going to a Tier One dungeon, right?" he asked, eyeing the absurd arsenal. "This is a reconnaissance and skill testing exercise, not a siege on a capital city."

"You can never be too prepared, Instructor Wade!" Kaela declared, adjusting a sword that was clearly digging into her ribs. "What if my first sword breaks? Then what?"

"The second one? Then what?"

"You genuinely can be prepared, Kaela," William said slowly, as if speaking to someone who had never encountered basic logic. "But there is an entire category of preparation called ’overpreparation,’ and you have crossed that border and started sprinting into the next territory."

Kaela blinked at him with flawless sincerity. "I don’t recognize that category."

"I’m aware."

On the other side of the shed, Ellie offered a stark contrast. She arrived considerably more subdued than usual, her usual cheerful energy replaced by a brittle nervousness.

She kept fidgeting with the leather strap of her satchel, her knuckles white.

When William noticed the way her shoulders were hunched toward her ears, he softened his tone. "Ellie? You alright?"

"Enclosed spaces are harder to control mana output in," she admitted quietly, refusing to meet his eyes. "There’s less room for a spell to dissipate safely if I overshot the target radius."

"If I miscalculate..." Her voice trailed off, the memory of her last magical mishap hanging between them like a guillotine blade. "After the hedge incident, I’m just... I want to be careful."

"I don’t want to accidentally bring the ceiling down on us."

"That’s exactly the right instinct," William reassured her, stepping closer to offer a grounding presence. "We’ll start you slow."

"Small, controlled test spells in open spaces before we move to anything that matters."

"We’re not rushing you into a cave full of goblins until you’re comfortable."

"No forty percent overshoots today," she promised, though her voice still wavered.

"You said that before the forty percent overshoot, too," William reminded her gently.

"This time I mean it... I’ve practiced the containment circles until my fingers cramped."

"I’ll believe it when I see it."

Before the conversation could deepen, Olivia appeared. She slung her satchel over one shoulder with practiced precision, wearing the carefully neutral expression of someone who had already prepared three separate academic justifications for her presence before anyone had even thought to ask.

"I’m coming along," she announced before William could even open his mouth to state the party limit. "For research purposes."

William sighed. "Olivia, this isn’t a field trip..."

"I wish to observe the practical application of combat theory within a genuine field environment," she countered smoothly, adjusting her glasses. "It is essential for my own instructional development to see how magical variables interact with real-world monster physiology."

"You just want to see the dungeon," William said flatly.

Olivia stiffened, her nose tilting upward. "That is a wildly reductive and frankly insulting interpretation of my academic motivations."

"Olivia."

"Fine! Yes! I want to see the dungeon!" she snapped, the facade cracking just enough to reveal the genuine excitement underneath. "I’ve been teaching theory for weeks, and I have genuinely never once seen a real monster up close in a controlled setting."

"I think that’s a reasonable gap in my professional experience worth correcting!"

"It’s a dangerous gap, but I suppose I can’t stop you from being reckless."

Finally, Catherine arrived. She had already changed into a plain, practical set of traveling clothes, dark leathers, and sturdy boots that favored mobility over formality and carried herself with the weary authority of someone who had expected this exact level of insanity.

She took one look at Kaela’s overloaded frame and let out a long, soul-deep sigh.

"Kaela, put the axe back."

"It’s for emergencies!" Kaela protested, clutching the weapon.

"What specific emergency requires an axe?" Catherine asked, her voice dripping with exasperation. "As opposed to the sword you’re already carrying, the two other swords you’re also carrying, and the dagger that is currently threatening to puncture your own kidney?"

"You never know!"

"I do, in fact, know," Catherine said, stepping forward and holding out an expectant hand. "Because I’ve seen the packing list, and there is no scenario in a Tier One dungeon that requires four separate weapons for one person."

"You’ll be too slow to move, and you’ll spend more time untangling yourself from your own gear than actually fighting."

Grumbling something incoherent about ’proper tactical readiness,’ Kaela reluctantly surrendered the hand axe.

However, as Catherine turned to speak to William, Kaela’s hand immediately darted toward her bag, her eyes darting sideways.

"I saw that thought happen on your face," Catherine said, without even turning around.

Kaela froze mid-reach, her expression going blank. "I wasn’t thinking anything."

"You were absolutely thinking something... And if that axe ends up in your boot, you’re carrying it all the way to the dungeon entrance."

Ellie, meanwhile, had retreated to the far edge of the shed, seeking refuge from the escalating chaos. She stood with her eyes pressed shut, her lips moving in a rapid, silent murmur as she recited the incremental control exercise like a prayer.

She was mentally rehearsing every sequence, the precise finger flick to release a spark, and the measured breath to contain a gust, building a fortress of discipline around her magic to prevent another catastrophe.

Clara stood beside her, a grounding presence in the storm of preparation. Every few seconds, Clara would pause her own work to offer a low, steady word of encouragement between scribbled notes in her ever-present leather journal.

She was currently documenting baseline mana readings in enclosed environments, her pen moving with clinical precision.

"You’ll be fine, Ellie," Clara said, not looking up from her page but speaking with absolute conviction. "You’ve been hitting the ten percent increments perfectly for three days straight."

"Your control is stabilizing." She paused, then added pointedly, "So, just... make sure there are no incidents today."

Ellie flinched slightly, her eyes snapping open. "There was almost an incident yesterday."

"Almost doesn’t count in magical theory," Clara countered smoothly.

"It felt like it counted," Ellie whispered, her fingers twisting nervously in the fabric of her robes. "The air felt like it was about to ignite, and I could feel the pressure building behind my sternum."

"It didn’t." Clara closed her journal with a decisive, satisfying snap. "You’re overthinking this because of the hedge."

"You’re letting one bad moment become a permanent identity."

"The hedge was one bad day," Clara added with a small, genuine giggle that broke through Ellie’s spiraling thoughts. "You’re allowed to have one bad day without it defining every day that follows."

"Even the best mages have days where they accidentally turn the garden into a charcoal pit."

Ellie managed a small, watery smile at that. The visible tightness in her shoulders eased fractionally, though the underlying anxiety remained coiled like a spring.

By the time William finally called the group together, the full party was assembled. It was an odd procession: four students, a weary but vigilant Catherine, and Olivia trailing behind them with an enthusiasm so barely contained it bordered on the comical.

They made their way through the city streets, their boots clicking against the cobblestones as they trekked toward the low, tree-covered hill where the Tier One dungeon entrance waited.

The mood during the walk remained deceptively light. Kaela was in rare form, regaling anyone within earshot with an increasingly embellished and physically impossible retelling of William’s morning demonstration.

In her version, William hadn’t just moved; he had practically danced through the air while summoning lightning from nowhere.

"And then," Kaela said, gesturing wildly with her hands, "the sword glowed brighter than the sun itself!"

"I thought we were all going to go blind!"

"That’s not what happened at all," Lia interjected sharply, her brow furrowed in irritation as she checked her notes. "His mana output was impressive, yes, but the luminosity was within normal parameters for a Stone configuration."

"Don’t be dramatic, Kaela."

"Dramatic? I’m being accurate!" Kaela shot back with a grin.

Behind them, Clara remained in her own world, quietly sketching the passing scenery with delicate strokes, while Ellie continued her slow, controlled breathing exercises, each inhale a conscious battle against her own nerves.

Catherine walked near the front alongside William, her silence creating a bubble of seriousness around them. Though her expression remained as composed as ever, William couldn’t help but notice the subtle tells.

Her hand drifted toward the hilt of her sword every few minutes, an old, involuntary habit of a warrior assessing a potential threat, and there was a faint, persistent tension in her shoulders that refused to dissipate.

The closer they got to the stone archway of the dungeon entrance, the more she seemed to transform from an amused instructor back into something sharper and more dangerous. The air itself seemed to grow heavier as the shadow of the dungeon loomed ahead.

’I do hope this training will end well... without—fuck, I shouldn’t say something that could raise a red flag.’
