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

William huffed out a quiet, amused breath that sounded more like a derisive snort. "You’ve got timing, I’ll give you that."

"Right when I’m already warmed up."

[The Harem Training System recognizes a significant milestone,] the interface pulsed with a soft, golden radiance that seemed more intimate than its usual clinical blue.

[You have officially secured two committed bonds within your harem.]

[Catherine Blackwood and Lia Valestria: both fully acknowledged, both mutual, and both genuine.]

William’s lips curled into a wry, almost bitter smile. "You say that like it’s an achievement I unlocked in some fucking game."

"Like I just found a rare item after grinding through a dungeon."

[Functionally, that’s not far from accurate,] the system’s tone carried its usual mixture of detached formality and a strange, barely concealed amusement. [And as with any meaningful milestone, this one comes with a reward.]

[Allow me to introduce Harem Boost.]

William crossed his arms over his broad chest, leaning his weight against the wall. His muscles still hummed from the phantom swordplay, his pulse still elevated.

"I’m listening. Make it worth my while."

[Harem Boost is precisely what it sounds like,] the system explained. [Once activated, all of your core attributes, strength, speed, endurance, and reaction time, receive a direct multiplier based on the number of official members currently within your harem.]

[With two committed bonds, you currently qualify for Harem Boost Times Two.]

William froze. His eyes narrowed as he processed the raw implications of those words. "Times two?"

"As in... I get twice as strong, twice as fast, and twice as durable, simply because I’ve secured two genuine relationships?" The thought was terrifying.

If his strength already allowed him to cleave through bone and steel, doubling it would make him less of a man and more of a walking catastrophe.

[Correctly and mutually committed relationships, yes,] the system clarified. [The multiplier scales with genuine, reciprocated bonds, not casual flings or one-sided obsessions.]

[The system rewards depth of connection, not mere quantity for its own sake. It feeds on the resonance between souls.]

"That’s..." William paused, his mind racing through the tactical advantages. "That’s actually a genuinely absurd amount of power to hand out for something that isn’t even a combat milestone."

"You’re turning emotional intimacy into a weapon."

[The system was built around the premise that love and connection generate real, tangible strength,] the system said, sounding almost proud. [I did warn you, quite some time ago, that the mechanics reward genuine bonds rather than manipulation.]

[This is simply the next expression of that principle.]

[Passion fuels the fire; commitment sustains the flame.]

William exhaled slowly, the implications settling into his bones like lead. He could feel the potential power thrumming beneath his skin, a latent energy waiting to be unleashed.

"Okay. Fine. But what about points?"

"Is that coming back now, or is this replacing it the way that other upgrade tried to?"

[Not replacing it, no,] the system replied smoothly. [I recall your objection quite clearly from our earlier conversation.]

[Since Harem Boost now handles your baseline attributes, I’m prepared to offer something far more potent for points going forward.]

Rather than a currency to spend on pre-made trinkets, you will now be granted full creative freedom.

William’s interest piqued. "Creative freedom?"

[Precisely. Whenever any given individual’s affection progress and training progress both reach one hundred percent simultaneously, you will not receive a random skill.]

[Instead, you will be granted the power to design a unique skill of your choosing personally tailored to your needs, your desires, and the nature of that specific bond.]

William stared at the screen, his jaw tightening. The possibilities were endless.

No more picking from a limited menu of mediocre abilities.

No more settling for what the system thought he needed.

If he wanted a skill that allowed him to regenerate limbs mid-fight, or a technique that could shatter mountains with a single strike, he could simply create it.

"So instead of browsing a list and picking something pre-made, I actually get to build the goddamn skill myself," he muttered, a hungry grin spreading across his face.

[Precisely,] the system concluded. [A more personal, more tailored reward, fitting the terrifying depth of the bond that produced it.]

...

William narrowed his eyes, studying the ethereal glow with the sharp, calculating suspicion of a man who had learned through blood and betrayal that any deal sounding this generous almost always came with a hidden price.

His mind instinctively began running through the worst-case scenarios: curses, soul-binding contracts, or some catastrophic backlash.

"And how many times does this happen?" he asked, his voice dropping to a low, dangerous rumble. "Is this some limited time offer?"

"A ’twice in a lifetime’ kind of deal because I only have two people in my harem right now?"

[There is no upper limit,] the system replied.

Its tone shifted again, carrying something suspiciously close to delight, a digital satisfaction that felt uncomfortably human. [The opportunity remains available indefinitely, so long as you continue to train new individuals and choose to welcome them properly into your harem as committed bonds.]

William stared blankly at the pulsing notification for several long seconds, the implications sinking in like stones in a well. "So you’re telling me the system’s entire incentive structure is, quite literally, keep dating more women, and I’ll keep making you stronger."

[I would phrase it with slightly more dignity, but yes, that is essentially correct,] The system answered without a shred of remorse.

"That’s genuinely ridiculous," William muttered, rubbing a hand over his face. "You’re essentially gamifying emotional intimacy to create a super soldier."

[It’s also, from a purely mechanical perspective, extremely effective,] the system countered smoothly. [You’ve objected to very little about this system that wasn’t rooted in genuine ethical concern, and I notice you’ve raised no such concern here.]

[You seem to find the proposition... acceptable.]

William opened his mouth to formulate a scathing rebuttal, to argue that he wasn’t some mercenary of affection, but the words died in his throat.

He couldn’t lie to himself. The raw power, the ability to reshape his own abilities, and doubling his physical capabilities were too intoxicating to dismiss.

He closed his mouth with a faintly exasperated huff, turning away from the screen.

"I’m not out here collecting girlfriends like trophies just because you’re offering a discount on raw power, for the record," he growled, though the defensive edge in his voice lacked real conviction.

[Nobody suggested you were doing that, William,] the system said, its words dripping with a patronizing calm. [I am simply pointing out that the incentive exists, should circumstances ever naturally arrange themselves that way.]

[Fate has a way of rewarding those who are prepared to seize it.]

William turned back to the interface, a muscle twitching in his jaw. "You sound suspiciously pleased about this."

"Like you’re enjoying this little game as much as I am."

[I contain multitudes,] the system said.

William froze. Then, to his own surprise, he laughed out loud, a genuine, surprised bark of amusement.

Hearing his own signature line thrown back at him with such deliberate, teasing precision was something he hadn’t expected from a collection of algorithms and data.

"Did you just quote me?" he asked, incredulous.

[I’ve been listening to you say it for months, William.]

[It seemed appropriate given the current context of our... partnership.]

William shook his head, unable to fully suppress the grin that tugged at the corner of his mouth.

The tension of the morning, the weight of the coming duel, the memory of Lia—it all felt momentarily lighter, buoyed by this strange, twisted camaraderie with his own power source.

But the grin faded as quickly as it had appeared, replaced by the grim resolve of a warrior preparing for slaughter.

"Alright. Fine," he said, his voice hardening as he regained his composure. "I’ll take the deal."

"All of it: Harem Boost, the custom skill option, everything."

"But I want something crystal clear before we move forward with any of this."

[Go ahead,] the system responded, the glow steady and expectant.
