[Ding, player triggered a special quest: Invasion of Outer Demons.]
[Evil and lustful demons have invaded this world and planted marks on unsuspecting girls. Remove all marks from the afflicted, locate and eliminate the demons.]
[This quest carries no reward, but failure will result in all marked females transforming into succubi.]
The cheerful blue of the system window did nothing to soften the weight of its message. Hozuki Nozomi's expression darkened instantly, jaw tightening as he processed the implications.
This mark... it actually turns girls into succubi?
[Succubus Imprint: Only exceptionally beautiful girls qualify for marking. The imprint heightens the bearer's allure to males, induces hypersensitivity throughout the body, and compels the marked to brand other beautiful girls through physical contact. Transformation accelerates with arousal.]
Kaguya Shinomiya watched his serious expression with growing unease. The afternoon light filtered through the venetian blinds, casting ladder-shadow patterns across her porcelain features. She smelled faintly of jasmine and the particular dusty sweetness of old paperwork—Student Council business never ended.
"I've seen this mark on others," she said carefully, dark eyes searching his face. "Nozomi... what happens if it isn't removed?"
He wouldn't look this grave over nothing trivial.
She didn't believe ordinary people could remove a mysterious magical brand. His power was her only option.
"If left untreated, your body becomes increasingly sensitive. Your attractiveness to the opposite sex multiplies." He met her gaze directly. "Eventually... you'll transform into a legendary succubus. Permanently."
"Hiss—a succubus?"
Kaguya Shinomiya drew a sharp breath through her teeth. Heat crept up her neck and bloomed across her cheeks—she couldn't help imagining herself with wings, a tail, that insatiable hunger mythology described...
No. Absolutely not.
"I don't want to become a succubus." Her voice came out smaller than intended. "Is there... do you have a way to solve this?"
She looked at him with undisguised hope, abandoning her usual cool composure.
Nozomi flashed a set of white teeth at her, settling onto the leather sofa with deliberate casualness.
"Of course it can be solved. I'd hardly let a graceful beauty like Kaguya-san transform into some lustful demon."
Relief washed through her so intensely her shoulders actually dropped. "Then... what do you need? I'll cooperate fully."
His hands rubbed together. He spread his arms wide, patting his lap.
"Simple. Sit here. Don't move. I'll purify it directly."
The warmth in Kaguya Shinomiya's expression frosted over immediately. She stared at him with eyes that could freeze mercury.
"...Are you sure."
It wasn't a question. Her tone suggested imminent violence.
I have never once heard of anyone purifying evil through cuddling.
"Completely sure. This mark isn't ordinary. Physical contact allows me to concentrate my energy properly—channel it through direct proximity."
Her stare didn't waver. "You're not simply trying to take advantage of the situation?"
"Kaguya-san." He placed a hand over his heart, expression wounded. "Time waits for no one. The longer you delay, the faster the transformation progresses. Do you want to sprout wings by dinner?"
The mental image made her shudder.
Kaguya Shinomiya released a defeated sigh through her nose.
Fine. If he's lying, I'll make him regret it later.
With deliberate dignity, she smoothed her skirt beneath her, adjusted the fabric to ensure no embarrassing bunching would occur, and carefully lowered herself onto his lap.
His thighs were firm beneath her. Warmer than expected. The scent of him rose around her—clean soap, something faintly herbal, and underneath it all, unmistakably male.
She held herself stiffly upright, refusing to lean back.
Even if he genuinely wanted to exploit this situation, she had no choice but to accept it. Removing the mark took priority. She was the young lady of the Shinomiya family—decisive action now meant she could helpKujo Maria-Senpai afterward, and even Chika if necessary.
She suspected their recent illnesses connected to this mark somehow.
Just endure it. Think of it as a necessary sacrifice for—
His arms wrapped around her waist.
"Nn—!"
The soft cry escaped before she could stop it. His chest pressed against her back, solid and radiating heat that seemed to sink straight through her uniform blouse. His breath ghosted warm against her ear.
"H-Hozuki Nozomi!" She twisted her head away, face blazing crimson. "What do you think you're—"
"Helping you." His eyes remained closed, expression irritatingly serene. "Stop talking. You'll break my concentration. Beginning now."
A pure, sacred light bloomed from his body, washing over them both in gentle waves.
Oh.
Perhaps I... misjudged.
Kaguya Shinomiya forced herself to breathe slowly. He'd mentioned the mark induced sensitivity. The electric awareness prickling along every inch where their bodies touched—the shameful warmth pooling low in her belly—
It's just the imprint. A physical reaction. Nothing more.
She tried desperately to ignore his embrace. But his breath kept feathering against her neck. The warmth of his chest pressed firm against her spine. His arms held her waist with a security she'd never experienced from another person.
Is this what men feel like?
He felt... safe. Solid. Like something she could lean into without fear of collapse.
"Pah! Pah! Pah!"
Realizing where her thoughts had drifted, Kaguya Shinomiya shook her head violently, cheeks burning.
What am I thinking?! Get a hold of yourself!
Meanwhile, Hozuki Nozomi worked quickly. He genuinely needed to hurry—no telling how many beautiful girls across the city bore sucubus imprints by now.
But his gaze kept drifting to her neck.
Slender. Snow-white. That delicate curve where her dark hair fell aside to reveal the pink mark pulsing just below her hairline.
An impulse surged through him.
He leaned closer.
His lips brushed the mark—soft, deliberate, unhurried.
At the same moment, he cast Water Purification.
"Aahn—!"
Kaguya Shinomiya's entire body seized. Her spine arched involuntarily, pressing her back flush against his chest. Her breath came in sharp, shallow gasps, eyes flying wide.
What—why—that sound—
The moan that had spilled from her throat echoed in her ears, utterly shameless and impossibly lewd.
Her thighs pressed together unconsciously. Heat flooded between them, sudden and mortifying. The mark on her neck burned, then faded—she felt it dissolve like morning frost under sunlight—but the sensation of his lips lingered. Tingled. Ached.
Did he just—
Her hands flew to cover her face, unable to look at anything.
Hozuki Nozomi drank in the sight of her for several satisfied seconds. Then, wearing a mild smile, he lifted her effortlessly and deposited her on the adjacent cushion.
"Done. Mark removed." He stood, rolling his shoulders. "But others remain affected. Rest here, Kaguya-san. I'll handle the rest."
She peeked through her fingers, mortification and lingering heat warring in her expression.
"W-wait." Her voice came out embarrassingly husky. She cleared her throat. "Kujo Maria-senpai from second year. I noticed the mark on her."
"Understood."
He waved over his shoulder and vanished—literally disappeared between one blink and the next.
Kaguya Shinomiya sat motionless on the leather sofa.
Slowly, her fingers drifted to her neck. Touched the spot where his lips had pressed. The skin still felt warm.
He kissed me.
That perverted, shameless, advantage-taking—
...quite responsible...
...person.
Her thoughts grew hazy, eyelids heavy, body still humming with residual sensation she refused to name.
After leaving the Student Council building, Hozuki Nozomi materialized in the center of Soubu High's empty athletic field.
Finding every marked girl individually would take forever. The system offered no navigation for this quest.
So he chose the obvious solution.
Cheat.
"Frieren." He spoke to empty air. "Rain spell. City-wide."
Magic gathered. Clouds darkened overhead, spreading with unnatural speed across the afternoon sky. The first drops fell—warm, soft, smelling of petrichor and ozone.
Then came the miracle.
"Water Purification."
Holy light exploded outward, riding the rain, touching every surface, every person, every shadow in the city.
Kujo Maria, halfway back to her classroom with a skip in her step, felt sudden warmth bloom across the back of her neck. The persistent heaviness she hadn't even consciously noticed lifted. Her body felt lighter—clean in a way soap couldn't achieve.
Hm? That was strange.
She shrugged and continued skipping.
Across the city, in hospital rooms and apartments and classrooms, girls blinked in sudden relief as pink marks dissolved from hidden places on their bodies.
Crisis resolved.
One skill.
Now for the mastermind.
Hozuki Nozomi activated the system's navigation function. A golden arrow materialized, pointing southwest.
He followed.
[Municipal Hospital, Third Floor]
"Water Purification!"
Light blazed through every window, every wall, every corridor.
"GYAAAHHHH—HOT—SO HOT—I'M—I'M MELTING—!"
A female succubus mid-mark-planting on an unconscious patient screamed as holy water saturated the very air. Her flesh bubbled, smoked, and evaporated in seconds—leaving nothing but a scorched outline and the smell of burnt sulfur.
