She gritted her teeth, barely able to respond. Her body trembled like it was tearing itself apart from the inside.
And just when his mind was about to snap—
[DING]
A voice echoed calmly inside his skull.
[System Notification: Evolution Detected.]
[Relax, Host. There is no danger.]
[Subject Selene Noctis is undergoing racial evolution. She is ascending from Three-Tailed Fox to Four-Tailed Fox.]
[You are advised to stand back and allow the process to complete undisturbed.]
Leon blinked, breath catching. "Evolution…?"
He took a cautious step back, watching helplessly as the glow intensified.
BOOM!
A pulse of light exploded from her form, forcing Leon to raise an arm to shield his eyes.
When the light began to fade… Leon slowly lowered his arm.
And froze.
Her skin flushed—hotter, tighter. The soft curves of her body seemed to reshape as he watched.
Her breasts swelled slightly, fuller, rounder, her nipples hardening and darkening, almost aching for attention. Her waist drew in tighter, making the curve to her hips more defined—sharper, more pronounced. Her ass lifted higher, firmer, but still plush and thick. It looked like a body sculpted for sin.
Leon's eyes trailed lower.
Between her thighs, her pussy glistened—not just wet from the pool, but from heat rolling off her body like steam. Her tails twitched violently, and then—
A fourth tail ripped free from her lower back with a small pop of energy. Sleek, perfect, and twitching as if testing its movement for the first time.
Selene's ears sharpened, a little longer now, the fur at the edges cleaner, more vivid. Her silver hair grew slightly in length, but darker streaks of blue now ran through it, especially at the tips.
She stood straighter, more confident. The glow faded—but she looked different now. Hotter. Wilder. More dangerous.
Leon couldn't look away.
"Selene…?" Leon said, stunned.
She turned slowly, giving him a small, teasing smirk. "Master…"
Her voice was different—silkier, deeper, more sultry. Yet still very much her.
"I feel… stronger. Sharper." She looked down at her hands, flexing them. "It's like every nerve is awake."
Leon couldn't help it—his eyes trailed over her new form. "You look… damn."
That earned him a chuckle. She stepped out of the water with a slow grace, her tails flicking behind her, droplets clinging to her skin before sliding off as if afraid to linger too long.
She stood before him, completely bare, power radiating off her like heat.
"Do you like it?" she asked, tilting her head.
"If I said no, I'd need my eyes checked," he muttered.
She giggled, clearly pleased.
"But seriously, how the hell did that happen?" he asked, tugging his pants back on.
"I'm not sure. One moment I was fine, then this warmth spread through me—slow at first, then it hit all at once. The rest… you saw." Her voice had a bit of awe in it.
She looked down at her hands, then at the four swaying tails behind her. "My kin stopped evolving generations ago. We clung to old stories of ancestors who reached the nine tailed form, nothing more. I thought we'd lost our path. But now" She looked up at Leon, eyes soft. "Maybe that path isn't lost after all."
She stepped in and kissed him—firm, grateful. "You're my lucky charm, Master. Promise you won't leave me."
And before Leon could say a word, she turned and walked out, humming, clearly too hyped to notice his stunned silence.
"I'm gonna tell everyone!" she shouted back.
Leon stood there half-dressed, hair still dripping, staring at the hallway.
"…Sure. Just leave me hanging. That's cool."
He sighed and buttoned up his shirt. "Alright, System. What the hell just happened?"
[You.]
Leon paused, pulling his shirt over his head. "What?"
[You are the reason. More precisely—your essence.]
Leon frowned. "You mean, my jizz?"
Leon frowned. "You mean… my jizz?"
[Not exactly. 'Essence' refers to any form of energy from your body—blood essence, soul fragments, or spiritual vitality. But in this case? Yes. Your semen carried the necessary energy to trigger her evolution.]
Leon paused. "…So my cum really did buff her into a four-tailed fox?"
[That's an oversimplification. But yes.]
Leon blinked. "Holy hell… I didn't know I was that loaded."
[It's not about the quantity. It's the quality. Your body has been transformed. When you absorbed the remnant soul of the Demon God during the Demon King Ascension, your entire being ascended past the mortal standard. That, combined with your Abyssal Sovereign Bloodline, turned your 'essence' into something potent enough to trigger evolution.]
"Right. So I'm basically a walking cheat code with balls."
[Your phrasing is crude. But not inaccurate.]
Leon smirked. "And yet, I'm still 'weak.' Right?"
[Extremely.]
"…You're lucky I can't punch you."
[I don't have a physical form.]
"Exactly."
He finally finished getting dressed and cracked his neck. "Don't worry. I'll get stronger. You'll see."
He stretched once, then made his way through the halls, brushing off lingering thoughts about how casual Selene had been about the whole thing.
A few minutes later, he pushed open the large stone doors and stepped into the dim-lit war room. A long oval table dominated the center, surrounded by his ten remaining retainers. Zorath was mid-sentence when he paused, looking up.
The rest followed.
