Dungeon Overlord: Monster Girl Harem!

The auction ended...

Asmodeus didn't intend to miss the last few items, but couldn't help it.

——

The velvet curtain rustled.

Erina looked up too quickly, caught herself, and smoothed her hands across her lap as if that would hide it.

Leonhardt entered first.

His coat hung from one arm, not worn. Leonhardt's torso was bare save for the open shirt hanging open lazily, revealing his abdominal and chest muscles.

Behind him, Zafira drifted like smoke on heat. Her cheeks still bore a high flush, her lips parted in a breathless smile, while folding her wings slightly inward, like they were trying to hide how they quivered and her tail, normally so lazy, twisted around Leonhardt's.

'Did Leonhard always have a tail?'

Zafira's tail wrapped around the thick, scaled tail with an elongated diamond tip, from the base to the sharp black tip, which flicked like a blade made from onyx and scaled leather.

'He looks so... good.' Erina thought.

Erina's throat felt dry.

She didn't understand it.

But her body shifted slightly in her seat. Her breath caught before she could stop it.

Leonhardt had changed.

Not just the tail. Not just the fine, dark scales now running like a hidden crest down Leonhardt's back and along his sides.

Not even the subtle, sharpened points to his ears, rimmed in what looked like metal—but wasn't. Erina noticed so many differences in his features, how they shimmered and glowed beautifully in the amethyst light.

Delicate, sleek scales down his sideburns and along his ears framing his face, shimmering black in the light. She knew thick armour like scales protected his back and his feet. But this looked more sensual and like an aesthetically pleasing look.

It was... the air around him.

Warmer. Heavier. Like a deep, calm breath drawn into the lungs and never released.

Erina's chest eased when Leonhardt came near, like he'd dragged the tension out of her body without touching her.

'What is this...?'

He didn't speak at first. He just let Zafira cling to his arm, her body draped close, face pressed against his shoulder, humming low like a woman who had just fed—and hadn't finished digesting it.

Mira didn't lift her head.

But she didn't need to because her quiet voice soon said everything.

"…You smell different now."

Zafira's smile sharpened, and she leaned forward, kissing Leonhardt's shoulder with a possessive little purr.

"Mhmm. Doesn't he?" Zafira giggled with a murmur.

Erina couldn't look away.

And that... was the worst part.

The room was quiet.

Too quiet.

Erina shifted on the velvet couch, forcing her gaze to the floor, to the table, to the empty wine glass near her elbow. Anywhere but him.

But it didn't help.

The air was still thick.

It wasn't an unpleasant scent, but like the aroma of baked fruits, sometimes sweet, sometimes bitter and musky.

It was something else—something soft and dense, like silk pressed against bare skin, like the moment before a kiss when you forget how to breathe.

She shouldn't be reacting like this.

She knew it.

Leonhardt hadn't even looked at her. Not once. He was too busy letting Zafira drape herself along his side, nuzzling into his neck with a grin that seemed too natural.

The succubus giggled—giggled, like a girl in love at a noble's party—and whispered something into his ear.

"You smell different now," she purred, pressing her chest into his arm. "Irresistible…"

Leonhardt exhaled slowly, not looking at her. "You're exaggerating."

"Am I?"

Her hand ghosted over the ridged black scales under his collarbone.

"Then why can't I stop touching you?"

"Because you're a pervert."

"I know, fufufu."

Erina didn't catch it.

But she caught the way his hand rested on Zafira's thigh slipping further between them afterwards, firm. Familiar.

Zafira's tail twitched, tightening around his.

Erina swallowed.

A bead of sweat trailed down her spine.

And then he looked at her for just a split second.

Nothing intense or overtly sexual, it was just a glance. Bare. Casual.

But her lungs locked.

The moment his crimson eyes touched hers, Erina felt her entire body tense, like the world tipped for a heartbeat.

She pulled her legs closer together.

'What is this?'

It wasn't magic. Not like any she'd felt.

But it did something to her. It settled under her skin, coiled like heat behind her ribs. She thought it was fear, at first.

Now she wasn't so sure.

Across the room, Mira stirred.

The strange girl lifted her head slightly, eyes flickering open just enough to stare at Leonhardt through pale lashes.

"You're leaking charm like a monster now."

"Mira... I am a monster." Leonhart's sharp fangs appeared with his grin, but the fairy just nodded with a blank face as if that settled everything.

Leonhardt leaned back into the cushions.

"It'll settle."

Zafira giggled again and threw a wink toward Mira.

"You say that," she teased, "but half the room's already in heat."

"Jealous?" Leonhardt asked.

"Mm… only when they start panting," Zafira replied, licking her lips. "But don't worry. I'll make sure no one else gets a drop."

Erina looked down again.

Her heart thud with a sharp ache spread through her chest as she wanted to deny it.

'Deny what?'

Was it that she was in heat, or that she was jealous and wanted him... even Erina didn't answer. No. She couldn't deny it.

That was the answer.

"We'll head out soon. This place is finished. I need to check the dungeon perimeter before morning."

Zafira shifted against him, her hand tracing down to his hip with exaggerated care. "Can't we stay a little longer? Let the little priestess adjust to the scent?"

"Zafira," he said. "Stop."

She pouted.

"Fine, fine. But only because your scales look too good right now. Hmph."

He didn't smile, but she still grinned, rubbing her cheek into his bicep with a contented hum.

"You like it when I show off, admit it," she murmured.

Leonhardt looked at her, then turned his gaze, again, back to Erina. He didn't speak, but when their eyes met, her lips parted with a faint gasp... hot breath leaving her lips as she trembled, gripping the sofa.

'Why...'

'I should hate you... want to resist you.'

Nobody spoke...

But the silence was loud.

And Erina…

'But I want you to touch me like her so badly!'

Leonhardt finally rose.

Not quickly. Not with that sudden force he sometimes wore like a cloak. Just… moved. Quiet and decisive.

His coat slung lazily over one shoulder, collar loose, chest still bare, he looked less like a warlord and more like some mythic creature forced to walk upright. Not because he had to—but because it amused him.

He turned to Zafira first.

"Take Mira," he said, his voice low, but not cold. "Return to the dungeon. Use the western gate."

Zafira blinked.

Then blinked again.

"Now?"

The word slipped out with a strange tilt to it. Almost playful. Almost pained.

Leonhardt didn't answer.

He didn't need to.

Zafira's fingers tightened around his forearm. Not hard. Just enough to say I'm still here.

Her wings didn't move. Her tail stayed wrapped around his. But something in her face turned. Just slightly. Just enough for Erina to see the way her breath caught when Leonhardt didn't pull her close again.

"…You're not coming with us?" Zafira's voice was silk and smoke, but not without edge. "You'd rather stay here—with her?"

Leonhardt's gaze flicked to Erina just once. Then back.

"I have business."

Zafira tilted her head, but her smile didn't reach her eyes this time. It was too sharp. Too still.

Her gaze flicked to Mira—slow, deliberate.

"That fairy girl… seems awfully obedient," she said, voice soft like lace stretched over steel. "You sure she isn't trying to steal more than your attention?"

Mira didn't respond.

Didn't even blink.

But Zafira leaned closer, her tail uncoiling from Leonhardt's and twitching once.

"If she looks at you like that again…" she whispered, just loud enough for both of them to hear, "I'll burn off those pretty wings myself."

The air went still.

Not tense—just quiet. Even Mira didn't flinch. She only looked up at Leonhardt and nodded once.

"I'll go," she said simply. "If that's your wish."

Zafira's jaw flexed.

Her smile didn't waver—but the heat behind it cooled like a blade returning to its sheath. She stepped away from Leonhardt like she hadn't been wrapped around him minutes before.

But as she passed him, she slowed.

"If I come back," she murmured under her breath, a dark sensation spread, causing the room to tingle... the dark magic of a level 101 creature enough to kill Mira and Erina instantly.

However—

"Eh?"

Before she could say another word—before the threat fully formed—his lips brushed her cheek.

Not deep. Not long. Just enough to silence her.

"Don't get jealous, Zafira," he murmured near her ear. "I like it when you smile most."

Her eyes widened.

Just a little.

Not from surprise, but from something worse—confusion.

Her hand paused mid-air, fingers curling at her side, and her tail twitched once, as if unsure whether to lash out or cling tighter.

She didn't answer right away. Her gaze flicked to the floor, then to Erina, then back to Leonhardt. Her lips parted—but no sharp words came.

Just a low murmur.

"You say that like I'm easy to please…"

She pulled Mira gently now, no longer yanking. Her fingers wrapped around the fairy's wrist like silk binding something precious.

Then she stepped back, the shadows curling tighter around her legs.

"...I'll take her home," she said, soft, almost pouty. "But you'd better come home to me, exactly how I left you!"

Her wings folded with a sulky snap, and she glanced at him one last time.

This time her smile was smaller, genuine and lovely.

And when she vanished in a blur of black petals and dusk-light magic—it felt less like a retreat…

And more like a promise.
