Anime Group Chat in a Doomsday World!

"The murderer, Natsuki Subaru… the replaced minister…"

Nanashi pinched his chin, deep in thought.

It had to be an anomaly.

But neither side seemed to have made contact yet, and even the Doomsday phenomenon hadn't been triggered.

Creak—

The sound of the bathroom door swinging open interrupted his thoughts.

"Nanashi-kun..."

A soft, melodic voice called his name.

He stopped thinking about the two worlds and looked up.

"!!!"

What the hell?

Nanashi's eyes widened.

At that moment, Marin's appearance rendered him speechless.

Her smooth, flawless skin was barely covered, only the essential areas concealed—if it could even be called that.

A dot-line type of coverage.

But what shocked him even more…

Two red horns protruded from Marin's head.

A thin black tail swayed playfully behind her, ending in a small, heart-shaped tip.

Across her smooth, toned abdomen, pink heart-shaped markings glowed faintly.

His gaze drifted back to her face.

No cosmetic contact lenses.

Her crimson eyes were completely natural.

Her lips, a deep shade of red, looked almost intoxicating.

And when their eyes met—

A fire of temptation burned within them.

"Hehe~"

Despite the bold attire, Marin smiled triumphantly.

On one hand, this was her way of repaying him for saving her life.

She hadn't forgotten what she promised.

On the other—

She wanted to mess with him.

The Doomsday Game…

In the Doomsday Game, Marin had gone on a rampage, annihilating alien invaders and earning over 30,000 survival points.

When she left the game, all her points were automatically consumed and converted into abilities best suited for her.

And the power she received—

"Succubus."

Yes, that kind of succubus.

The kind that could stir people's deepest desires, seduce, and control through sheer charm.

Once she transformed, she could enchant and manipulate both men and women alike.

Of course, before transformation, certain physical traits changed.

Her horns, her tail, the heart-shaped markings, even the shimmering silver patterns on her stomach.

But her clothes—

They didn't vanish.

No, she had specifically designed this succubus cosplay outfit as her way of thanking Nanashi for saving and protecting her.

And right now—

She stood before him, clad in only a few thin strands of fabric.

Nanashi remained seated, unmoving.

"Hehehe, have I bewitched you?"

Seeing him seemingly mesmerized, Marin took a confident step closer.

She reached behind him, grabbing a small bag.

From it, she pulled out a revealing set of black attire.

Lowering her face until their noses nearly touched, she stared straight into his eyes.

The fresh scent of soap mixed with the sultry aroma of a succubus lingered in the air.

She smiled mischievously.

"As I thought… Nanashi-kun's face is perfect for cosplaying as Duke Shi Run from Hell!"

Holding up the black ensemble, her grin widened.

"Come on, Nanashi-kun! Put this on and let me admire the Duke of Hell in all his glory!"

"…"

That outfit was insane.

Duke Shi Run—the male lead of a certain infamous series.

Nanashi hesitated for a moment.

Then, obediently, he raised his hands.

He unbuttoned his shirt and shrugged it off.

"Gulp!"

Bare, toned arms.

Lean, perfectly sculpted muscles.

And that ridiculously handsome face.

At such close proximity, Marin couldn't help but swallow.

Her throat felt dry.

"A-Ah!"

Suddenly, Nanashi stood up.

His heated body brushed against hers—bare skin against barely-covered skin.

Marin instinctively stumbled back.

Had he snapped out of her enchantment?

But then—

She saw him reach for his belt.

"!!!"

His weapon was seen again.

And it was only centimeters away from her.

Even through the thin coat, its presence was undeniable.

Last time, in the Doomsday Game, she had accidentally caught a glimpse before leaving the cabin.

Now, the memory resurfaced.

Marin shook her head violently, her face burning.

"T-This is way too much, no matter how you look at it!"

Just as Nanashi moved again—

She quickly reached out to stop him.

"Hey! Wait, wait, wait! Stop!"

But in her panic, she accidentally swung her hand too hard—

And struck exactly where she shouldn't have.

"…"

Nanashi's brow twitched.

He had intended to play along for a little longer.

But now?

Forget it.

His patience had run out.

Without hesitation, Nanashi reached forward, grabbed Marin by the shoulders—

And pushed her onto the bed.

"Ah! Hey!!!"

Marin let out a startled yelp as she was pinned down beneath him.

She blinked up at him, confusion in her eyes.

"W-Why…? Why aren't you following my commands?"

Nanashi smirked, amusement flickering across his face.

With his left hand, he effortlessly pinned both of her wrists above her head.

His strength made it impossible for her to resist.

"Did you really think I could be controlled?"

He leaned in slightly, voice low and teasing.

"I can suppress even my own instincts. What makes you think your little tricks would work on me?"

His eyes trailed downward.

There was no rush to admire the "main course."

Instead—

His right hand reached out and—

Grabbed her swaying tail.

"Ah!"

Marin shuddered violently.

A deep crimson blush spread across her cheeks.

"D-Don't touch my tail!"

Nanashi raised an eyebrow, twirling the small heart-shaped tip between his fingers.

"Horns, a tail, glowing silver markings, and the ability to drive people insane with desire…"

His voice was laced with curiosity.

"What exactly are you, Marin? A succubus?"

He smirked, watching as her body trembled beneath him.

Nanashi's hands didn't stop.

He gripped the thin, swaying tail, running his fingers along its length.

It seemed to be just as sensitive as the rest of Marin's body.

Every time he moved it, her body trembled involuntarily.

Her breath hitched, and her half-lidded eyes grew hazy. She bit her lip, determined not to make a sound.

After a pause, she finally managed to speak in a slow, almost breathless voice.

"It's… it's a succubus."

Nanashi's expression immediately darkened.

"So, you really were trying to control me with your charm just now?"

Afraid that he might be angry, Marin quickly waved her hands in panic.

"I'm sorry! I only did it because I wanted to see Nanashi-kun cosplay as Duke Shi Run! I was wrong! Please forgive me!"

Nanashi narrowed his eyes.

"Forgive you? Sure. Do you know how to properly apologize?"

"Huh? An apology? Do you want me to bow?"

Nanashi shook his head.

"Then… should I do a seated apology?"

Another shake of the head, followed by a tsk. "Tsk tsk, you really don't get it, do you?"

Marin blinked in confusion.

With complete seriousness, Nanashi declared, "If you truly want to apologize, you have to show some skin."

"W-WHAT?!"

Marin's face turned scarlet. She looked down at herself.

"…There's barely anything left to show!" she shrieked, flailing in embarrassment.

In her frantic movements, she accidentally brushed against something she absolutely shouldn't have.

"…"

Nanashi gave her a strange look, his gaze unreadable.

"…Did you do that on purpose?" he asked, his tone calm but his eyes sharp.

"H-how could I?!"

Her heart pounded as she averted her gaze, her denial weak at best.

Nanashi simply smirked and, without warning, ran his fingers over the heart-shaped tip of her tail.

"!!!"

A full-body shudder wracked through Marin as she gasped.

Her face was now completely flushed.

Nanashi chuckled.

"Well, your apology seems sincere enough. I'll forgive you—just don't try to seduce me again."

Feeling that he had collected enough 'interest,' Nanashi released her tail and let go of her wrists.

Just as he was about to get up—

—He couldn't move.

"…?"

For a brief moment, he was stunned.

Marin, still gripping the bedsheets tightly, trembled beneath him.

Then he felt it.

A faint heat.

From that small scrap of fabric between her legs, something warm pressed against him, seeping through.

"…"

Realization dawned on him. His eyes widened slightly as he looked at her.

Marin covered her face with both hands.

Then, without warning, she scrambled off the bed, bolting for the bathroom.

By the time they left the hotel, Marin kept her head down, silent.

Even with her usual bright and carefree personality, there was no way she could act normal after what had just happened.

Nanashi, on the other hand, remained unfazed.

If anything, he was in a good mood—after all, he had gotten his fair share of entertainment.

Instead of lingering on the awkwardness, he focused on analyzing Marin's ability.

Earlier, she had only given him a brief explanation.

To put it simply, she could transform into a succubus.

And as a succubus, she could awaken desire in living creatures and, in turn, control them.

The more he thought about it, the more absurd it sounded.

'Living creatures' didn't just mean humans.

Those affected by her ability would become enthralled—similar to how he used the Dominator to control mindless puppets.

Nanashi glanced at her, his voice calm and thoughtful.

"I think your ability might affect you as well. You should probably use it less in the future."

The uncontrollable state she had been in earlier…

It was hard not to suspect that her power had an influence on her.

"…Mm."

Marin gave a small, muffled response.

Her heart pounded.

The truth was, there was something she hadn't told Nanashi.

If a succubus faced someone she had feelings for, she would be affected by anti-charm.

In other words…

It wasn't her succubus ability affecting her.

She had been the one drawn to Nanashi.

She had fallen under his spell.

But how could she ever admit that?

Wouldn't that be the same as confessing?

Her mind was in complete disarray.

She had only met Nanashi a few times.

So why was she already so attracted to him?

…Well, he was incredibly strong and handsome in the Doomsday game.

He had saved her. Protected her.

Today had felt almost like a date.

Nanashi had taken care of her.

He always indulged her small whims.

And he was… surprisingly gentle.

Even the way he held her hands felt nice…

"Ah—!"

Marin quickly patted her cheeks, trying to snap herself out of it.

She couldn't let herself think like this!

Nanashi has a girlfriend!

It must be my ability messing with me—it has to be!

"Hey! Watch the road!"

Before she could react, Nanashi grabbed her wrist and pulled her into his chest.

A car horn blared as a vehicle sped past.

The realization struck her.

If Nanashi hadn't stopped her, she would have been hit.

She looked up at him in shock.

Nanashi's expression was dark, his grip firm.

"Don't space out while crossing the street! Can't you see the red light?"

His scolding was sharp, his voice filled with frustration.

Marin fell silent.

She stared at him.

The way he had pulled her to safety.

The way he was reprimanding her with genuine concern.

At that moment, she finally understood.

It wasn't her ability affecting her.

It wasn't some external force.

This was her own problem.

Her own feelings.

In the evening, Nanashi accompanied Marin home.

His main concern was whether her condition had been affected by the succubus's abilities.

Of course, this was just a guess—he didn't know the truth.

Faced with his concern, which carried an unclear mix of good intentions, Marin didn't refuse. Instead, she readily agreed.

After stepping off the tram, Nanashi was about to hail a taxi when Marin ruffled her hair and smiled.

"My home isn't far from here. Would you like to walk back with me, Nanashi-kun?"

"Of course."

As they walked, Marin returned to her usual lively and cheerful self.

She hopped here and there, occasionally tugging at Nanashi's sleeve.

Nanashi humored her with patient indulgence.

As they strolled side by side, her fingers brushed against his—over and over again, always seemingly by accident.

Nanashi glanced at her suspiciously.

Yet every time, she would act as if nothing had happened, her expression unreadable.

After the umpteenth time, he had had enough.

This time, when her fingers brushed his, Nanashi acted decisively—he grabbed her hand.

There was no longer any pretense of innocence.

Marin didn't look surprised. Instead, she gave him a half-smile—one of quiet satisfaction, as if her plan had succeeded.

That's when he understood.

I was being teased.

How can this be tolerated?

Without hesitation, he interlaced his fingers with hers, firmly intertwining their hands together.

"…"

The evening breeze blew gently, carrying the quiet warmth between them.

Marin's cheeks turned slightly pink.

Neither of them spoke.

They simply walked like that, hand in hand, all the way to Marin's doorstep.

"We're here," Marin finally broke the silence.

"Alright. Go inside—I'll head back now."

Nanashi loosened his grip and released her hand.

Marin took a few steps toward her door.

Then, suddenly, she stopped.

Before Nanashi could question it, she spun around and ran back to him.

"You didn't forget anything, did you?" he asked, puzzled.

"Hm… I did forget something," she said with a playful chuckle.

Standing on tiptoe, she gently cupped Nanashi's face with both hands.

Then, softly, she pressed a kiss to his lips.

It was light, fleeting—there and gone in an instant.

Before he could react, Marin had already stepped back, her smooth hair swaying as she turned.

At the doorway, she glanced back and waved.

"Nanashi-kun, I had a great time today. Let's do this again sometime, okay?"

Nanashi, still processing the moment, smiled faintly and waved back.

"Okay."

With a bright, satisfied smile, Marin disappeared inside.

Under the soft glow of the streetlamp, Nanashi lightly touched his lips.

The taste wasn't bad at all.
