Non-Human Girls Are Fighting Over Me ~ Do I Get to Refuse? “Nope!” “No Way!” “Not a Chance!” “Absolutely Not!” - Chapter 28 & 29

Chapter 28: Riri-chan

In the dim darkness.

A formless “thing” drifted, like bubbles rising from murky water.

No outline. Just pure black.

No voice, only a trembling “presence” lingering there.

Soon, a chilling delight seeped out.

A voiceless voice. It struck the ears, clawing at the depths of the heart.

“…Not yet. Still trapped in this cage. But—”

Silence followed, mocking in its weight.

Bound by a feeble existence, crushed, forced into a long slumber.

Yet the fragile chains, thin as ice, could no longer hold.

“…Soon. The time of return will come.”

The darkness quivered.

A vibration like distant thunder, an unsettling sound of something stirring.

Resentments piled upon the underside of the world.

Hatred and lamentation.

The embers of a fire that once burned all, insatiable, now stirred back to life.

“This time…”

The low murmur carried unwavering obsession.

“This time, I’ll burn this world to ashes. Reduce everything to dust, destroy it all…”

A chilling heat spread.

The darkness began to take form—a massive figure, wings, or perhaps fangs.

Its shape still vague, but its pressure undeniably growing.

A breathless tension seeped into the world’s cracks, unnoticed.

No one saw it. But it was surely approaching.

“…The time of return is near.”

Thursday after school

Thursday evening. Just back from school, I felt something off before stepping through the front door.

A large truck parked in front of the neighbor’s house. The movers had already loaded everything, now checking the final details.

“…Moving?”

I muttered, and in that instant—

“Onii-chan~♡”

A soft voice and a sudden impact as someone hugged me from behind.

Small arms wrapped around my shoulders. Their delicate warmth stopped my heart for a moment.

“Huh…?”

Turning around, I saw—a familiar girl with blonde twin-tails.

A large black ribbon, a black dress swaying lightly.

She looked like a high-grade elementary or middle schooler. Her chest was still modest, her features distinctly youthful.

But the glint in her eyes was inexplicably seductive for her age, leaving me speechless.

“Riri-chan…? …It’s been, what, five years? You’ve grown.”

At my words, she flashed a shy smile.

“Hehehe~♡”

Her smile was pure innocence. Yet the slight tilt of her head, the narrowed eyes, carried a dangerous sweetness.

Then, a voice from the doorway.

“My, it’s been a while.”

Riri-chan’s mother. Long blonde hair, refined features. As a half-Japanese, she had the dazzling aura of a movie star.

I straightened instinctively.

“Oh… Auntie. You’re back with Riri-chan.”

“Yes, indeed. My husband will join us later. We were just about to come greet you.”

Her elegant smile made me let out an involuntary “Wow,” which must’ve shown on my face.

From behind, Riri-chan whispered softly.

“…Onii-chan. Making eyes at my mom… are you a cheater?”

“N-no, that’s not…”

I coughed to cover it up.

Riri-chan giggled “Hehe” and tightly squeezed my hand.

“Let’s get along again.”

In that moment—

In a breathy whisper no one else could hear, she continued.

“Onii-chan… you’ll keep that ‘promise,’ right?”

Her smiling face was no longer that of a young girl.

Under the moonlight, she was as bewitching as a grown woman—chillingly so.

Friday.

On the dusk-lit way home, Riri Aikava, carrying her schoolbag, turned a corner with light steps.

In that instant—her world froze.

“There… Onii-chan!”

She started to call out with a smile. But seeing someone beside him, her blood turned to ice.

A high school girl with flowing black hair. Her slender figure stood out against her white blouse.

—And he was smiling at her.

(…What’s this… why…?)

Her chest tightened. She couldn’t breathe.

It felt like the sound of that day’s promise breaking.

“—Oh, Riri-chan! Welcome back!”

His innocent voice stabbed her.

Onii-chan, oblivious, introduced her with a smile.

“This is Riri Aikava, our neighbor. She’s back in town.”

The high school girl smiled warmly and introduced herself lightly.

“Hello, Riri-chan. I’m Towa Tsukina. Nice to meet you.”

(…She’s stunning. Beautiful. Cute… who is this woman… his girlfriend…?)

Her ears burned, but her body felt like ice.

He and Towa disappeared into the house, leaving Riri behind.

No words came.

She stood there, stunned.

(Why… why… you promised, didn’t you…?)

Her lips trembled, tears threatening to spill.

But that night, despair struck deeper.

—She saw him and Towa walking hand-in-hand, lover’s style.

※

The next day.

Visiting to study with him, she heard from his family—

“Sorry, he’s staying over somewhere today.”

He didn’t return until Sunday.

(It’s… over…)

Her world sank into darkness.

Slumped over her desk, Riri opened an old notebook.

A childish vow written in a young hand.

“Ugh… ugh… why… why… you promised… we had a contract… why…”

Tears stained the page.

But abruptly, her sobs stopped.

A low voice, unlike that of a young girl, echoed instead.

“…No choice, then.”

Without turning, she commanded.

“—Come.”

Behind her, a black shadow shimmered. A non-human presence seeped from the darkness.

“You called?”

No form was visible. But something obedient was undeniably there.

“Yes… investigate Onii-chan. Seems some bad bugs are clinging to him. Likely ‘non-human.’ Don’t let them notice.”

“Yes, ma’am.”

The shadow vanished.

In that moment, Riri’s lips curled into a wicked, cold smirk, unthinkable for an elementary schooler.

“I’ll take you back no matter what… Onii-chan.”

Under the moonlight, her golden eyes held no trace of youth, only bottomless darkness.

—The girl was surely stepping toward her demonic self, Lilith.

Chapter 29: The Demon of Paradise Lost

One week later.

Riri Aikava’s room—once belonging to a girl by that name—was now another world entirely.

No pale pink curtains, no childish stuffed animals. Everything was dyed in darkness, with a single chair at the center.

Seated on it was a beautiful girl, appearing seventeen or eighteen.

Clad in a black dress, her glossy blonde twin-tails were tied with black ribbons.

Her perfectly proportioned figure exuded a seductiveness far beyond girlhood, her red-painted lips exhaling breaths that felt almost lascivious.

The demon Lilith.

Lilith Celestia Noctis.

—The “Demon of Paradise Lost” and the “Demon of Lust.”

True to her name, she radiated an otherworldly brilliance, commanding shadows at her side.

“…Report.”

Her low, sultry voice fell.

The shadow, as if pressing its forehead to the floor, spoke.

“…As you command. Onii-sama is currently in the clutches of a vampire and a witch, exploited daily as a sex slave. Subjected to violence, deprived of proper human meals… at times, even his body…”

“—!!”

Lilith’s eyes widened. Her grip on the chair’s armrests tightened, her pale fingers trembling.

“No… that’s a lie. It has to be a mistake…! Something this horrific…!!”

“Regrettably, it is an undeniable truth.”

The shadow’s voice was flat.

But to Lilith, each word pierced like a blade.

“…Unbelievable… a vampire and a witch… treating Onii-chan like…! Enslaving him, abusing him, stripping him of human dignity… toying with him on a whim… that’s… the work of demons…!”

Lilith muttered in a trembling voice.

“—No. Worse than any demon…”

Tears streamed down her cheeks, falling hotly to the floor.

Covering her face with both hands, she shuddered, stifling sobs as she continued.

“Why… why did he endure such cruelty to survive…? Yes… it must be… Onii-chan held onto our ‘promise’ as his only anchor…!”

In that moment, a certainty bloomed within Lilith.

No doubt, no hesitation. Her delusions consumed her, converging the world into a single truth.

“Onii-chan… it was so hard. So painful. But you did so well…! You endured because you believed in our promise, didn’t you…♡”

Her lips formed a sweet smile, glinting with madness.

“It’s okay now. I’ll take everything back for you. The vampire, the witch… I’ll burn them to ashes, despair and all!”

Rising, Lilith’s black dress flared, like a queen descending from the abyss.

Her tear-streaked eyes gleamed as she spread her arms skyward.

“I’ll save you, I promise!! Wait for me, Onii-chan♡”

Her voice was sweet yet laced with spine-chilling madness.

Thus, the delusion-driven demon Lilith began to act.

The next day, after school.

In the deserted film club room, two girls faced each other.

Towa Tsukina—her pristine black-haired beauty framed by a cold, ruthless smile.

Before her sat Mio, the crimson-eyed witch, her seductive aura dripping with venomous words.

“About our last talk—the bit about nullifying the saintess’s blood,” Towa began.

“Right,” Mio replied, her lips twisting into a provocative smirk.

“If you give him—Kazuto—to me completely, I’ll make it happen. Not a bad deal, right?”

“—No need,” Towa shot back instantly.

“Kazuto is mine alone. I’ve overwritten him with a powerful Possession Sigil. Deep in his soul, he can’t defy me. I won’t let you have your way.”

Her voice was clear, yet it oozed a mad love.

“Hmm…” Mio traced her lips with a slender finger, smiling seductively.

“But my Possession Sigil is carved even deeper. Even in the next life, Kazuto is mine. With a binding of submission, no less.”

“Then… I’ll just overwrite it again,” Towa retorted, her tone defiant.

Their voices clashed, the air in the club room growing taut.

Kazuto, present at the scene, couldn’t hold back.

“Uh, um… isn’t this the kind of talk you have when the person’s not around?”

But both girls turned simultaneously, snapping coldly.

“—Shut up.”

“Just leave it to us.”

Their voices, perfectly synced, carried the tone of absolute dominance.

Kazuto shivered.

In that instant—

The air shifted.

A chilling sensation crawled up their spines. The club room was enveloped in black mist, light sucked away into darkness.

“What…?” Towa frowned.

“The barrier… activated on its own…?” Mio’s eyes narrowed.

From the depths of the darkness, the sound of heels echoed.

Click, click, click…

A blonde beauty in a black dress emerged.

Her golden hair was tied in twin-tails, black ribbons swaying.

Her features were almost too perfect. Her mature figure radiated a commanding seductiveness.

The demon—Lilith.

“You two… enough is enough.”

Her voice, cold yet trembling with fury, resounded through the club room.
