It was time for all the students to go home.
Nate grabbed his bag, as he saw Kurumu looking at him.
She passed him a note.
She left after doing that, and Nate opened it. "Rooftop".
Nate sighed. 'There it goes'.
The rooftop door creaked open to a warm sunset glow — orange and pink streaking across the sky, wind gently tugging at Kurumu's ponytail and miniskirt. She stepped out first, hips swaying with practised confidence, then turned to watch Nate follow.
He looked completely relaxed — hands in pockets, golden-amber eyes scanning the horizon like this was just another after-school hangout.
Kurumu's heart thumped harder than usual. He's even cuter up close. 'That aura… It's like he's used to this.'
She closed the distance in three graceful steps, pressing right up against his chest — her large breasts squishing softly against him, arms looping around his neck as she tilted her head up.
"As a succubus," she purred, voice low and honey-sweet, pupils already shifting into perfect little hearts, "I have many powers. It's easy for us to get mates. We choose a primary one… and then other partners. So, with that said…"
She leaned in closer, lips brushing his ear.
"I want you."
Nate looked down at her — calm, steady, no blush, no panic.
"Okay."
Kurumu froze.
Her heart-shaped pupils widened to saucers.
"…What?"
Nate gently unwrapped her arms from his neck (not roughly — almost politely), then walked past her toward the railing, leaning against it casually as he gazed at the sunset.
"I already have a harem," he said matter-of-factly, like he was commenting on the weather. "If you wanna join, fine then. You're in. I just need to tell the others. We can go on dates tomorrow if you like that."
Kurumu stood rooted to the spot, mouth slightly open.
'He… just… accepted? Like that? No begging? No charm overload? No "please be mine forever" dramatic speech?'
Her tail (illusion dropped in her shock) flicked wildly behind her, betraying her inner chaos.
"You—" she stammered, cheeks flushing for real this time. "You just… said yes? Just like that?"
Nate glanced back over his shoulder, a small smile tugging at his lips.
"Yeah. You're cute. You're honest about what you want. And your aura feels… nice. Not pushy. Just… real." He shrugged. "Why not?"
Kurumu's pupils flickered — hearts pulsing faster now, but mixed with genuine surprise.
Most guys fell over themselves for her. Begged. Drooled. Lost their minds.
This boy just… shrugged and said "You're in."
Nate kissed her on the cheek. "Listen I don't have the patience for a Romance arc, we can discuss over text where you want the date, tomorrow".
Kurumu was still frozen when Nate stepped back beside her, resting his elbows on the railing.
The wind brushed past them, carrying the sound of students leaving the school below.
She covered her face with both hands.
'This is not how this is supposed to go.'
"…You're impossible," she muttered, peeking at him through her fingers.
Nate chuckled. "I get that a lot."
She dropped her hands, eyes glowing—not with charm magic this time, but something real. "You know you just turned my whole worldview upside down, right?"
'Good,' Nate thought. 'Means she's thinking, not just acting.'
"I'm serious," Kurumu said. "Most guys want to own me. Or show me off. Or think I'm just—" she waved her hand vaguely. "You didn't do any of that."
Nate nodded once. "Yeah. I don't like that either."
There was a beat of silence.
Then Kurumu smiled—smaller, softer than before. "Tomorrow. A date. A real one."
Nate pulled out his phone. "Send me the place. I'll show up."
She laughed under her breath. "You really don't overthink things, do you?"
'Oh, I do,' Nate thought. 'Just not the parts people expect.'
As they headed for the door, Kurumu stopped him.
"…Hey, Nate?"
He looked back.
"I'm not backing out," she said firmly. "Just so you know."
Nate smiled. "Good. Neither am I."
They walked down the stairs separately—no drama, no fireworks—just the quiet understanding that something had shifted.
And somewhere else in the school…
Mizore sneezed for no reason at all.
'…Why do I feel like I just lost ground?'
Nate didn't even overthink it.
He lifted his phone.
Kurumu leaned in on instinct, pressing a kiss to his cheek with a playful hum, fingers flashing a peace sign.
Click.
Perfect.
A second later, the image dropped into the group chat.
Group Chat: "Nate's Girls"
Nate: [Image attached]
Nate: Just added her. Be nice.
Then—invite sent.
Kurumu Kurono has joined the group.
There was a solid half-second of silence.
Then—
---
Kunou: Welcome 😊
Kunou: I am the Queen, nice to meet you.
Kurumu: …WAIT WHAT?
Hailey: Oh.
Hailey: So this is happening already.
Fumika: That was fast.
Blizzaria: Hm. A succubus.
Blizzaria: Interesting choice.
Mizore: …
Mizore: Hello.
Serafall: She looks Cute.
Kuroka: Nya~ New members
Foiletta: Hello
Kurumu stared at the screen, tail flicking wildly behind her illusion.
'WHY IS EVERYONE SO CALM?'
Then more messages rolled in.
Hailey: Rules are simple.
Hailey: Don't hurt him.
Hailey: Don't manipulate him.
Serafall: Be friendly with all the girls
Kurumu blinked. "…Fair."
Fumika: If you do either, we fight.
Kurumu: …Still fair.
Kunou: You may sit next to him sometimes.
Kunou: But not always.
Kurumu: I—
Kurumu: …I understand?
Nate watched the messages roll by, relaxed.
'Yep. This is working.'
Then—
Mizore: …Are you loud?
Kurumu paused.
"…Excuse me?"
Mizore: When you're… affectionate.
Kurumu slowly typed.
Kurumu: I can be quiet.
Mizore stared at her phone for three full seconds.
Mizore: …Good.
Blizzaria smirked.
Blizzaria: Competition acknowledged.
Kurumu felt it.
That chill.
'So that's the ice girl…'
She smiled.
'This is gonna be fun.'

Meanwhile — After School, Y Academy Hallways
It spread in minutes.
Whispers turned into murmurs.
Murmurs into panic.
"He accepted her."
"No charm backlash."
"Didn't faint."
"He didn't even blush."
"She kissed him."
"He smiled."
A group of second-year boys stared at their phones in disbelief.
"That succubus… Kurumu Kurono?"
"And he just… said yes?"
One guy clenched his fist. "Who the hell is Nate?"
Another whispered, terrified, "That's the Yokai King."
Silence.
Someone swallowed. "Oh."
From a window above, a few hidden yokai watched Nate walk across the courtyard, Kurumu casually hanging off his arm like she'd earned the right.
"This school's balance just shifted," one muttered.
"Yeah," another agreed. "And it's only day two."
---
Back outside the gate, Kurumu glanced up at Nate.
"You know," she said lightly, "half the school wants to kill you now."
Nate shrugged. "Only half? That's an improvement."
She laughed—real laughter this time.
'Yeah,' she thought. 'I picked the right one.'
Later in the Adam House
Nate spoke. "This is Kurumu Kurono, a new addition to my Harem".
He was saying this as he was hugging Kurumu and burying his face in her big chest.
He allowed his perverted side let out a bit, mostly because he did this with all his girls
Lily just drank her tea.
Aaron did the same.
The Lily gave Aaron 20 Yen. "Ok, you win".
Nate looked up. "You guys were betting on something".
Aaron chuckled. "Yes son, how long will it take you to bring a new girl home, your mother said 1 month and I said 1 week".
Kurumu stiffened for exactly half a second—
Then relaxed.
Her arms wrapped around Nate's shoulders, one hand patting his head with a smug little smile, like she'd decided this was acceptable behavior.
"It's nice to meet you," she said sweetly, looking straight at Lily and Aaron. "I'm Kurumu Kurono."
Lily finally looked up from her tea.
She took Kurumu in—tail hidden, aura very much not, posture confident, eyes sharp in a way only dangerous girls had.
"Hm," Lily hummed. "Succubus."
Kurumu blinked. "…Yes?"
Lily nodded once. "Explains the chest."
Nate snorted.
Aaron laughed outright.
Kurumu's face flushed pink. "E-Excuse me—!"
Lily waved her hand dismissively. "Relax, dear. I've seen worse. And I married worse."
Aaron raised his cup. "Hey."
Lily slid the coin across the table with a sigh. "I really thought he'd last a month this time."
Nate lifted his head, offended. "Hey, I showed restraint."
Aaron tilted his head. "You brought her home on day two."
Kurumu leaned in slightly, whispering, "Is that bad?"
Nate shrugged. "Depends who you ask."
Lily set her cup down and finally smiled—warm, knowing, dangerous.
"Well," she said, standing, "welcome to the Adam household, Kurumu. Ground rules are simple."
Kurumu straightened immediately. "Yes, ma'am."
"One," Lily said, holding up a finger, "no mind control in this house."
Kurumu nodded quickly. "Of course."
"In week 1," Lily continued, "if you hurt my son, emotionally or otherwise—"
The temperature dropped just a little.
"—I will personally remind you why I'm called a Yokai Summoner."
Kurumu swallowed. "…Understood."
Then Lily's expression softened.
"And three," she finished, "dinner's at seven. If you have dietary needs, tell me now."
Kurumu stared.
Then smiled—genuine this time.
"Thank you."
Nate wrapped an arm around her again. "See? Told you my mom's cool."
Lily glanced at the way Nate was still very comfortably buried in Kurumu's chest.
"…Nate."
"Yeah?"
"Hands a little higher."
"Yes ma'am."
Aaron laughed into his drink.
Kurumu looked around the room, heart racing—not from charm, not from lust.
From realization.
'This family is insane.'
She smiled wider.
'…I think I like it here.'
Kurumu then grabbed Nate's face. "Nate, what are you?".
Nate blinked. "I am human".
Kurumu shook her head. "No, no human has that Aura, that power".
Nate looked at her as he kissed her on the cheek. "I am seer".
She blinked as everything made more sense. "I see that explains it".
"Also I am the Yokai King". He said casually, face still buried in her chest.
Kurumu froze.
Like—full system lock.
Her hands were still on Nate's face. His voice had been calm. Casual. Like he'd just said oh yeah, I'm left-handed.
"…The what?" she asked slowly.
Nate shifted slightly, finally lifting his head and giving her a sideways look. "Yokai King."
Silence.
Kurumu's pupils shrank.
Her wings flickered in and out of existence.
Her tail straight-up glitched.
Then—
"Oh."
She released his face, took one step back… then another… then sat down very carefully on the couch like gravity had personally offended her.
"That explains," she said, nodding once, "the aura."
Nod.
"The pressure."
Another nod.
"The fact that every Yokai in school looked like they wanted to kneel or scream."
Nod, nod.
Lily sipped her tea. "She's taking it well."
Aaron leaned over. "Better than the last one."
Kurumu slowly looked up at Nate again. "So let me get this straight."
"Shoot."
"You're human—but not really."
"Correct."
"You're a Seer."
"Yep."
"You casually sit at Z-class power."
"Mhm."
"And you're the prophesied Yokai King."
"Also yes."
Kurumu exhaled, leaned back, and stared at the ceiling.
"…Of course I fell for the Yokai King."
Nate shrugged. "You've got taste."
She let out a short laugh—half disbelief, half genuine amusement—then glanced sideways at him.
"You know," she said, voice softer now, "most kings would make a big deal out of that."
Nate smiled. "Sounds exhausting."
That earned him a real smile from her.
Kurumu stood back up, walked over, and poked his chest once—testing, confirming.
"Alright," she said. "New rule."
"Oh?"
She looked him dead in the eye. "Next time you casually drop world-shaking titles, maybe give a warning."
Nate laughed. "Fair."
She leaned in and kissed his cheek—quick, light, intentional.
"Still glad I joined," she added.
From the hallway, Kunou's voice echoed:
"Does this mean she's officially scary too?"
Kurumu smirked. "Oh, absolutely."
Nate grinned.
'Yeah,' he thought, 'this is gonna be fun.'
Kurumu then pointed at Mizore. "Why is she here".
Nate looked at her. "TLDR, her mom and my mom are friend and my mom said it was ok for her to stay here, because her family is in Hokkaido, and she still needs to go to school in Y Academy".
Kurumu nodded. "Did you two kiss?".
Nate looked at her. "Not yet, but we do this".
He got it as he went to Mizore and pulled out her Lolipop, as she put it in his mouth and then Mizore pulled back out and took it back in her mouth.
Nate looked at Kurumu. "Out side of Cheek kisses, we do indirect kiss, she is shy for a full out makeout".
Kurumu stared.
Then stared harder.
Then slowly turned her head back to Nate.
"…You're weird," she said flatly.
Mizore, still holding the lollipop between her lips, blinked once. Her cheeks puffed slightly as she looked away, ears turning faintly pink.
Nate shrugged. "She's shy. I respect that."
Kurumu crossed her arms, tail swaying lazily behind her. "Huh. Didn't expect that from you."
"I have standards," Nate replied. "And patience. Shocking, I know."
Mizore glanced at Kurumu, then at Nate, then quietly took one small step closer to him—close enough that her sleeve brushed his arm. She didn't say anything, just stayed there.
Kurumu noticed.
"Oh," she said, eyes narrowing with interest. "So that's how it is."
Mizore met her gaze. Calm. Silent. Not backing down.
Blizzaria, watching from the side with a cup of tea, nodded once. "Cold types," she said simply. "They move slow. But they don't lose."
Kurumu clicked her tongue, then laughed. "Alright. I get it now."
She leaned closer to Nate, lowering her voice just enough to sound teasing. "Guess I'll have to step up my game."
Nate sighed. "Please don't turn this into a competition."
Kurumu grinned. "Too late."
Mizore took the lollipop out of her mouth, thought for a second… then held it up toward Nate again, eyes still on Kurumu.
Nate paused, then leaned in and took it—quick, casual.
Mizore immediately took it back, satisfied, and went back to quietly existing at his side.
Kurumu burst out laughing. "Okay, yeah. She's dangerous."
From the kitchen, Lily called out, completely unbothered,
"Dinner in twenty minutes! Try not to start a territorial incident before then."
Nate looked between the two ice girls and muttered,
"…I miss when my biggest problem was homework."
'And it's only week 1,' he thought.
