[Koyanskaya rejected your proposal to meet the Dark Koyanskaya almost without hesitation. When you asked why, she fell silent.]
[You roughly explained your idea: although Light and Dark take different evolutionary routes, in essence they're both Beast IV—Light feeds on the system of human civilization, Dark Koyanskaya is made of pure hatred.]
[In the future, the Light Koyanskaya and Dark Koyanskaya are destined to fuse into a single complete Beast. If you can get the Dark Koyanskaya to accept human civilization, then the woman before you might one day ascend the throne of Beast IV with ease.]
[After hearing your explanation, Light Koyanskaya's face showed a hint of surprise.]
Just as Izaya had said, whether it was her or the Dark Koyanskaya, their growth paths were different, but their ultimate goal was the same—revenge on humanity.
If she could pull the Dark Koyanskaya into the same camp, then her future evolution would likely proceed ever more smoothly.
After all, if their evolution routes were truly identical, there would be no competition to begin with.
However, the premise of this plan was that Izaya would have to get closer to the Dark Koyanskaya.
"No."
Thinking this far, Koyanskaya refused almost instantly.
Her decisive answer even startled Izaya, who unconsciously blurted out:
"Why…?"
This was a plan he'd been turning over in his mind for a long time.
"No particular reason… I just don't want you getting close to her."
In her golden eyes, a subtle shift of emotion flickered.
Izaya fell into thought, then hesitated.
"Are you worried I'll be in danger? Don't worry, I do have some ability to protect myself…"
When Taigong Wang left this land, he'd clearly understood how important Izaya was to the Tunguska Sanctuary and had left him a parting gift, something that could protect him at critical moments.
With a special talent akin to intuition or clairvoyance, he could still cope with enemies, at least a bit.
But Koyanskaya shook her head gently and said in a quiet voice:
"I'm not worried about your safety… In the end, as long as I'm here, no one in this land can hurt you."
"Then—"
Before he could finish, Light Koyanskaya lifted her right hand. Her soft, pale fingertips gently brushed his cheek, bringing a faint coolness.
"Sajyou-kun, even if you want to help her, I don't want you getting close to that Beast…"
"It's not that I'm afraid you'll get hurt. It's because you're a captive I brought back… So the only opposite sex you're allowed to get close to is me."
She lowered her eyes slightly at the end, her unbelievably beautiful face slowly leaning closer to the boy's until she finally pressed her forehead lightly against his.
A lock of soft pink hair slid down his brow and brushed his lips.
Tilting her head slightly, she asked:
"Is that… no good?"
Of course it was no good.
No way that was "no good"…
It was more accurate to say she was going way too far, wasn't it?
Her words were full of willfulness, but in essence they were simply an expression of her own emotions and… desire.
This kind of need was no less intense than a confession.
It made him feel just a little ticklish inside.
As he looked into her golden eyes, which were now slightly hazy with shyness, and at her cheeks faintly flushed with intoxicated embarrassment, Izaya felt his heart subtly ripple.
He had lived two lives and had a fiancée, Sajyou Manaka, but in truth, Sajyou Izaya's experience with romance was absolutely zero.
And this special existence before him—a BEAST—was the first opposite sex who made his heart truly skip a beat.
To Izaya, she was first and foremost a woman, and only second a Beast.
Arrogant, alluring, mature—and right now, the jealousy and possessiveness spilling from her words were just short of overflowing.
To Koyanskaya, she simply refused to allow any woman—even her other self—to get close to Sajyou Izaya.
Faced with such deep affection from the Beast, Izaya smiled gently.
"I understand."
He softly held her small, white, tender hand.
"If you don't want it, then I'll withdraw that proposal… From now on, I'll keep my distance from the Dark Koyanskaya as much as I can."
At the boy's straightforward and unhesitating answer, Light Koyanskaya stared at him in a daze, then asked hesitantly:
"You… don't find it disgusting? Giving up on getting close to the Beast just because of my selfishness?"
"Not only do I not feel disgusted… I'm honestly very happy you value me so much."
Izaya smiled.
"By the way, this might not be the perfect timing… but it's not too late tonight yet, so… could you keep teaching me your magecraft?"
The moment those words fell, the Beast of this land—who should have been fundamentally hostile to humans—bloomed into a bright, radiant smile.
"Of course."
She gently tightened her hold on his hand and slowly, gracefully drew him into her arms.
Even through layers of fabric, he could feel the thrilling sensation of her soft skin.
Before Izaya could react, she embraced him tightly and pulled his face to her chest.
With the faint scent of her body lingering around his nose, and the perfect softness pressing down on him, Izaya felt himself lightly suffocating, and for some reason his mind flashed back to that one night's hazy experience.
Only, that time he'd fallen into a deep sleep; this time he was very much awake.
After a while, Koyanskaya slowly loosened her grip.
She lowered her eyes. Her pale golden irises reflected the beast of desire at this moment. Her delicate, seductive red lips came to rest by his ear.
"Tonight, I'll teach you a brand-new kind of magecraft… Take it slow, one step at a time, following my lead."
As she spoke, she guided one of Izaya's hands to gently stroke her cheek.
Softness followed.
The perfect curves that made hearts race, the form truly worthy of the title BEAST…
In the world of stars and moon, at least in Izaya's impression, every Beast possessed a human heart that could still be proud of itself.
He couldn't help but lift his head and gaze at the very enchanting pink-haired fox queen before him.
The instant their eyes met, he found his gaze drawn uncontrollably into her moist, tempting pupils.
No words were necessary. No instruction from her was needed. Sajyou Izaya knew exactly what he should do.
So he took the initiative to bend forward and gently pressed his lips against her soft red ones.
Her beautiful eyes flickered for a moment, and as their bodies entangled, the temperature in the air gradually rose.
After a while, their lips parted.
Koyanskaya exhaled like an orchid, her arms hooking lightly around his neck as she pressed his face against her chest again. Her damp, tempting lips brushed his ear.
A bewitching whisper flowed into the hazy air.
"Was that enough for you, Sajyou-kun…?"
That single sentence instantly reignited the ambiguous atmosphere.
The next moment, their fingers intertwined tightly.
The tent's curtain closed on its own.
A lattice of magical barriers rose overhead, completely cutting off all sound and the approach of any outsider…
Inside the sealed tent, the air thickened with an intoxicating mix of Koyanskaya's natural musk—wild cherries and ancient foxfire—and the faint hum of her magecraft weaving through the space like invisible threads. Izaya's heart pounded as she pulled him deeper into the dimly lit chamber, illuminated only by the soft glow of ethereal pink orbs floating above them, manifestations of her Beast authority over the Tunguska Sanctuary.
Koyanskaya's golden eyes burned with possessive hunger, her lips curling into a sly, predatory smile. "Sajyou-kun," she purred, her voice a sultry whisper that sent shivers down his spine, "this 'magecraft' lesson will bind us closer than any spell. But first... let's shed these useless barriers." Her fingers, tipped with sharp, manicured nails, traced the collar of his shirt, teasing the fabric as if it offended her.
Izaya swallowed hard, his cock already stirring to life beneath his pants at the mere promise in her tone. He'd never been this intimate with anyone, his reincarnated life leaving him a virgin in body if not in fragmented memories. But with her, the Beast who claimed him as her captive, it felt inevitable—fated, even. "Teach me," he murmured, his voice husky with desire, reaching up to cup her face.
She chuckled lowly, a sound like velvet over steel, and leaned in to capture his lips again, this time with more urgency.
Their tongues danced in a heated tangle, her taste sweet and addictive, like forbidden nectar from a Grail gone wild.
As they kissed, her hands worked deftly, unbuttoning his shirt with deliberate slowness, exposing his toned chest inch by inch.
She broke the kiss to trail her lips down his neck, nipping at his skin with her sharp teeth— not enough to draw blood, but enough to mark him as hers.
"Mine," she growled possessively, her breath hot against his ear. "No other Beast, no other woman, will touch what's mine."
Izaya gasped, his hands fumbling to reciprocate.
He slid his fingers under the hem of her elegant black dress, the fabric silky and enchanted, clinging to her voluptuous curves like a second skin. With a gentle tug, he pulled it upward, revealing the pale, flawless expanse of her thighs.
Koyanskaya shifted her hips to help, her tail—manifesting in a flicker of pink fur—swishing playfully behind her as she stepped out of the dress, letting it pool at her feet.
She wore nothing beneath, her body a masterpiece of Beast perfection: full, heavy breasts with rosy nipples already hardening in the cool air, a narrow waist flaring into wide hips, and between her legs, a neatly trimmed patch of pink hair framing her slick, swollen pussy, already glistening with arousal.
"Damn," Izaya breathed, the word slipping out as his eyes devoured her.
His cock throbbed painfully against his pants, begging for release.
She was exquisite, her skin glowing with an inner light, her intimate folds pink and inviting, dripping with the evidence of her desire for him.
Koyanskaya's laugh was throaty and triumphant.
"Such vulgar words from my proper captive? I like it."
She pressed her naked body against him, her breasts squishing against his bare chest, nipples like hard pebbles scraping his skin. Her hand snaked down to palm his erection through his pants, squeezing firmly. "Now, undress for me."
Izaya's hands trembled with excitement as he complied, shoving off his pants and underwear in one motion.
His cock sprang free, thick and veined, the tip already leaking precum, standing proud at a solid seven inches.
Koyanskaya's eyes widened with approval, her tongue darting out to lick her lips. "Beautiful," she murmured, wrapping her soft hand around his shaft, stroking slowly from base to tip.
Her touch was electric, sending jolts of pleasure through him as she pumped him with expert rhythm, her thumb circling the sensitive head.
He groaned, bucking into her hand.
"Koyanskaya... please..."
But she wasn't done teasing. Pushing him back onto the plush furs that served as their bed, she straddled his waist, her wet pussy hovering just above his cock, grinding her slick folds against his length without letting him enter.
The heat of her cunt teased him mercilessly, her juices coating his shaft as she rocked her hips, her breasts bouncing with each movement.
"Patience, Sajyou-kun," she whispered, leaning down to suck on his nipple, her teeth grazing it while her free hand pinched the other.
Izaya arched his back, moaning loudly, his hands gripping her ass—firm, round cheeks that filled his palms perfectly.
He squeezed, feeling the muscle beneath the softness, and dared to slip a finger between her cheeks, brushing her tight asshole.
She gasped, her eyes flashing with wicked delight. "Naughty boy... but I approve."
The first long scene of their union began as she finally lowered herself onto him.
Guiding his cock with one hand, she sank down slowly, her tight, velvety pussy enveloping him inch by inch.
"Ahh... you're so big," she moaned, her walls clenching around him like a vice, hot and wet, stretching to accommodate his girth.
Izaya thrust up instinctively, burying himself to the hilt inside her, feeling her cervix kiss the tip of his cock.
The sensation was overwhelming—her inner muscles rippling with Beast-enhanced control, milking him as she started to ride.
They moved together in a primal rhythm, her hips slamming down onto his with wet, obscene slaps.
Koyanskaya's breasts heaved, and Izaya couldn't resist sitting up to capture one in his mouth, sucking hard on her nipple while his hand kneaded the other, rolling the peak between his fingers.
She threw her head back, pink hair cascading like a waterfall, her moans echoing in the barrier-sealed tent: "Yes, Sajyou-kun! It's all yours!"
Sweat slicked their bodies as the pace intensified.
Izaya flipped her onto her back, driven by a surge of dominance he didn't know he had.
Now on top, he pounded into her relentlessly, his balls slapping against her ass with each deep thrust.
Her legs wrapped around his waist, pulling him deeper, her nails raking down his back, leaving red trails.
"Deeper..." she cried, her pussy gushing around him, the lewd squelching sounds filling the air. He reached between them, his thumb finding her swollen clit—hard and throbbing like a pearl—and rubbed it in circles, making her buck wildly.
Their first climax hit like a Servant Noble Phantasm.
Koyanskaya came first, her body convulsing, pussy clamping down on his cock in rhythmic spasms as she squirted, her juices soaking his thighs. "I'm cumming... Izaya, fill me!" she screamed, her golden eyes rolling back.
The sensation pushed him over the edge; with a guttural groan, he erupted inside her, pumping thick ropes of cum deep into her womb, overflowing and dripping out around his shaft.
But they weren't done.
Panting, Koyanskaya flipped him over, her Beast stamina endless. "Now, for the next lesson," she said with a wicked grin, positioning herself on all fours, her ass high in the air, pussy still leaking his seed.
"Do me from behind~."
Izaya knelt behind her, admiring the view: her puckered asshole winking above her glistening cunt, tails of pink hair framing the erotic sight.
He gripped her hips and plunged back in, the new angle letting him hit even deeper, his cock bullying her G-spot with every thrust.
This second scene stretched longer, their bodies slapping together in a frenzy.
Koyanskaya pushed back against him, meeting each thrust, her moans turning into feral growls.
"Harder~!"
Izaya obliged, one hand reaching around to finger her clit while the other spanked her ass, leaving red handprints on her pale skin.
She loved it, her pussy fluttering around him. He even dared to press a finger against her asshole, dipping it in slowly, feeling the tight ring grip him as he double-penetrated her with cock and digit.
Hours blurred into a haze of passion.
They switched positions again—her riding him reverse cowgirl, her ass bouncing as she ground on his cock.
Each orgasm built on the last, her Beast nature allowing her to recover instantly, drawing out his pleasure until he was spent, collapsing beside her in a tangle of limbs.
As dawn approached, Koyanskaya curled against him, her head on his chest, fingers tracing lazy patterns on his skin. "That was your magecraft lesson, Sajyou-kun," she whispered, satisfied and possessive.
"Bound by body and soul. Remember... you're mine alone."
Izaya, exhausted but content, could only nod.
