I Took A Succubus's First Time

"Amemiya Kyouka, the leader of the Amemiya Faction, and the traitor Sugisawa Masaki..." Satoshi's grin widened, voice dripping with venom as his hungry eyes danced over them. "Fuckin' beautiful pairing, really. I gotta admit—I'm dying to see what a former captain of the demon army, who's been clashing with angels for years, looks like when her guts are ripped out and blood's spilling everywhere. Sounds fun, don't you think?"

His tongue slowly traced the edge of his blade, leaving a glistening line of saliva as he stared them down, almost shivering in delight.

"And as for you…" Satoshi's gaze slid to Masaki, his tone turning even colder, almost mocking. "I'd really love to see what the inside of a traitor's brain looks like. Cut it out, stuff it in glass, and spend a nice long while figuring out what fucked-up thing drove you to turn your back on your own people."

"You're really fucked in the head, y'know that?" Masaki shot back, disgust thick in her voice as her eyes locked on Satoshi's crazed grin.

Satoshi was a demon jester, those freaks who looked like clowns on the outside but were born killers underneath. Masters of murder who could end a life so quietly that you'd never even see it coming.

"Sick? Me? Nah, not even close," Satoshi chuckled darkly, head tilting just a bit, like a predator sizing up prey. "Hell, I once pulled my own brain out of my skull and dissected it, piece by piece, just to check if anything was wrong. Turns out, I'm fuckin' perfect."

He sounded so sure, as if that insane act actually proved something normal about him. And the scariest part? He meant every word. Nobody even knew how the hell he survived it—and he wasn't exactly sharing the secret.

"Kyouka-sama, he's dangerous as hell. Please be careful," Masaki murmured to Kyouka, her voice quieter now, edged with worry her grip on her weapon tightened, knuckles whitening.

"I know," Kyouka answered, calm and steady, though the faintest steel glinted in her eyes. Her hand clenched tighter around her sword's hilt.

She had fought countless battles as well as survived endless wars. She could sense power and danger just by the way someone breathed. And this bastard wasn't bluffing—she knew that much.

But Kyouka had once led entire armies of demons against angelic legions. She had turned hopeless battles into victories. Even if her body now carried scars and old wounds that slowed her down, her fighting spirit still burned just as fierce.

"You can go help the frontlines, Masaki," she told her, lifting her blade and shifting into a ready stance.

"Ooh? Facing me alone?" Satoshi chuckled, voice dripping with a twisted delight. "That's gutsy. Kinda hot, too, not gonna lie."

Masaki hesitated, then met Kyouka's gaze. She nodded once, firm and calm, and Masaki finally backed off, trusting her to handle it.

Satoshi's grin twitched, excitement practically vibrating in the air around him. Kyouka wasn't just anyone. She was the demon captain who'd led victories against the angels. But back then she'd been at her peak; now she carried old injuries. Even so, her killing intent was still razor sharp.

"Now then… it's just us. Let's dance," Satoshi purred, his voice low, almost playful—but behind that was something hungry and lethal.

And then, like smoke caught in the wind, he vanished.

Kyouka's eyes barely caught the flicker of motion—and steel met steel with a harsh clang as she blocked his sudden attack. Sparks crackled, scattering like fireflies.

Satoshi vanished again, reappearing behind her, blades flashing toward her back.

She twisted, pivoting on her heel, sword catching his blades with another shower of sparks.

"Hoho! You're better than I thought! Fuckin' great!" Satoshi cackled, his grin so wide it almost split his face.

And then, gone again—air swirling where he'd stood.

"But can you keep up with me?!"

Kyouka's breathing stayed steady, focus like a drawn bow. She could still read the faint disturbance of mana, the subtle shifts of air—just enough to see where he'd appear next.

Steel clashed again and again, each impact ringing sharp in the air. Satoshi was fast—fast enough to blur like a ghost—but Kyouka's reflexes, honed by war and bloodshed, didn't falter.

Over and over, she parried, sparks lighting their dance like fleeting stars.

But then—a sting. Just a thin line of pain, hot and sharp on her arm.

"Fufufufu… no matter how quick you are, once I catch up, you're done," Satoshi whispered, licking the drop of blood from his blade, eyes narrowing like a viper tasting its prey.

Kyouka's gaze hardened, hand tightening, chest rising with a silent breath. Maybe, just maybe, she'd underestimated this monster.

Meanwhile, Aria and Nagisa were tearing through the frontlines, bodies moving like lightning, eyes locked on the wave of enemies ahead.

The Love Link burned inside them, flooding every muscle and vein with wild, scorching power. It felt like their hearts could burst—but in the best way possible.

Aria's sword became a streak of silver fire, each swing cutting down foes like wheat under a scythe. Her speed wasn't just fast—it was brutal, and the force behind each blow cracked the ground under her feet.

Beside her, Nagisa's fists hit like meteors. Bones shattered, demons flew back like broken dolls, the shockwaves of her punches echoing across the battlefield.

They were the sharp tip of the spear—clearing a bloody path so the succubus and incubus forces could press forward, bit by bit.

But then, Nagisa's stride faltered, breath catching as a figure stepped into view, standing before a fresh wave of towering oni.

"You naughty little brat~…" Yuzuha drawled, voice sweet as poisoned honey. Her smile curled cruelly, eyes glinting with malice.

Behind her, the oni stood like a living wall—huge demons whose raw, crushing power turned them into walking engines of destruction. They didn't need mana as they could break you with a single swing.

"Yuzuha…" Nagisa hissed the name like venom, every muscle in her body tensing, hate burning hot and fierce behind her eyes.

The one person she despised more than anyone else in this fucking world had finally stepped onto the field.

"Oh? You sound kinda mad… why is that, I wonder?" Yuzuha teased, tilting her head slightly, her lips curling into that mischievous, almost mocking smile. Her eyes glinted, playful yet cruel, as they locked onto her niece.

Nagisa didn't bother answering. She just stared right back at Yuzuha, her jaw clenched tight.

This woman—this fucking woman—was the one who had betrayed her mother.

It was only natural that Nagisa felt this rage burning in her chest.

But right now, in the middle of war, letting her anger get the better of her would mean opening herself up to a fatal blow—and she knew she couldn't afford that.

She had to stay alive. She had to make it out.

"You're really disappointing, Nagisa. Honestly, I thought you'd turn out more like your mother," Yuzuha sneered, her words dripping with scorn. "But instead? You're nothing compared to her. Pretty pathetic, don't you think? My sister—even as an oni—carried herself with grace. But you? You don't have an ounce of it. You really are nothing next to her."

Nagisa's teeth ground together so hard it hurt. But she swallowed the rage back down, forcing her breathing steady.

"Fight me, Yuzuha. Fair and square. Just the two of us," she shot back, her voice sharp, eyes locked onto her aunt.

"Oh?" Yuzuha raised a single eyebrow, amused. "What's this now? You sound like you actually think you've got something up your sleeve. Or is it just that you're scared to fight us all at once?"

"Oh, I'm not afraid of that at all, Yuzuha," Nagisa retorted, voice low but firm. "Actually, I'd say I've got enough confidence to take you all at the same fucking time. But if it came to that, wouldn't that make you the one who's scared to face me alone?"

A vein bulged visibly on Yuzuha's forehead, her playful smile twitching into annoyance.

"Oh, I see how it is… Fine then," she exhaled slowly, her voice icy. "If you're so damn set on this, I guess I'll humor you for a little while."

Yuzuha didn't even need to transform—she was already in her oni form with her skin turned a deep blood‑red, two horns jutting from her forehead, her body towering and rippling with strength.

Nagisa took a slow breath, heart pounding. It was her turn.

She'd never shown Kouhei her real oni form—not out of shame exactly, but because a small part of her feared he might look at her differently. Unlike Yuuna, whose vampire form was still beautiful, or Hina, whose succubus form wasn't far from human, Nagisa's was raw, fierce, and monstrous.

Her skin turned a dark, vivid red and her muscles grew harder, her body taller and broader. And from the side of her forehead, a single horn curled forward—not centered, but slightly off to the side. It wasn't some perfect twin set of horns like most onis had. Just the one.

She was an anomaly among her kind. But right now? She didn't give a thing about it.

Because Kouhei wouldn't stop loving her for this—she believed that with everything she had.

The air seemed to tighten as Nagisa's transformation completed. Her chest rose and fell heavily, eyes narrowing as they locked on Yuzuha's.

The space around them hummed with killing intent, thick enough to feel on the skin.

And just like that, the fight between Nagisa and Yuzuha was about to erupt.
