Chapter 9: No Pervert Allowed
Author: Geraint
With my parents gone on vacation overseas and taking Fuyumi with them, I suddenly found myself with nothing to do. Normally, I'd be looking after my baby sister. Now, I was just sitting on the couch, staring at a box of condoms—one my dad had intentionally left behind.
He was the one who encouraged me to... get closer with my step-sisters while they were away. But I hadn't even confirmed their feelings for me yet. What if they hated me for even bringing it up?
"I'm home!"
Shiina's voice called from the front door. I jumped and immediately shoved the box into my pocket.
"Welcome home!"
I turned to greet her, surprised that she was alone.
"Huh? Where are Yuuka and Lilith?"
"Yuuka's got training today for her performance this weekend, and Lilith went with her as a bodyguard."
"I see."
That's when I noticed something odd.
"Did you roll around in the park? You've got leaves in your hair."
I got up from the couch and approached her, gently picking the leaves out of her long hair. She froze, her face turning bright red.
"U-Umm... There was this cute cat I saw and... I followed it into the bushes. I just wanted to pet it, but it ran away."
"You shouldn't wander off like that. It's dangerous to walk around alone—especially for a girl."
"Seir-kun! I'm already in high school. Stop treating me like a child, like my mom does! I can take care of myself!"
"I am treating you like a lady. You're really cute, and I wouldn't be surprised if guys on the street took an interest in you. Next time, just call me if you're heading home alone, alright?"
Her eyes widened as she looked at me.
"Wait... Can you say that again?"
"Huh?"
"You said I was 'really cute.'"
"It's true. You are."
Her face turned even redder. "I-I'm going to change!" she squeaked, rushing past me and holding her hands over her blushing cheeks.
When she came back, she was wearing a white sleeveless blouse and a blue skirt—her usual loungewear. She sat beside me on the couch and slowly leaned against me, resting her head on my shoulder, just like she always did.
After a while, I asked her quietly, "Hey, Shiina. What do you think of me?"
"...What?!"
"I mean, am I just a childhood friend to you?"
"W-Why are you asking that out of nowhere?!"
I wrapped my arm around her waist and looked into her eyes.
"What's your answer?"
"You're being unfair, Seir-kun. You'd know if I lied. I... I still can't answer that."
I leaned in closer, staring at her lips. She trembled but closed her eyes, waiting. Her breathing was soft, expectant.
"Seir-kun..."
Our lips were just about to meet when—
"What are you two doing while I'm gone?"
Yuuka's voice sliced through the moment like a blade.
"Gyaaaaah!" Shiina shrieked and shoved me away, her face redder than ever.
"Yuuka?! Weren't you at training today?"
"I skipped."
Her tone was menacing. Behind her, Lilith stood frozen with a pale expression.
"E-Eh? Why?"
"Mom messaged me. She told me the three of them went on vacation, and Onii-sama would be alone at home. I had a bad feeling about it... and I was right! You two were just about to kiss!"
"Wait! Yuuka, let's talk about this!"
"What's there to explain? I saw it with my own eyes!"
"I—I'm sorry!" I bowed my head in surrender.
"Huh? What's this?"
She picked up the item that had fallen from my pocket.
My blood ran cold.
"Onii-sama... isn't this—?"
Her face turned red as she held it up.
"You PERVERT! This is a condom! Were you planning to use this on Ayaka?!"
Shiina's face turned pale.
"S-Seir-kun... is that true?"
"I HATE YOU, YOU SCUMBAG TRASH!" Yuuka screamed as she ran upstairs, slamming the door shut behind her.
"Seir-kun... we need to apologize to her," Shiina said gently.
"No... This is all my fault. You didn't do anything wrong."
"But still..."
As I was thinking of how to fix things, Yuuka came back downstairs, now dressed in a sleeveless, frilly white dress that barely reached her thighs, with black shorts underneath.
She was still glaring, but quietly sat on the other side of me and leaned back against my shoulder.
"Yuuka...?"
"I told Mom what happened. She got mad at me instead."
...Seriously?
Yuuka pointed at Shiina with trembling hands.
"Listen up, Ayaka! You're a servant in this house, just like your mom! You're not allowed to do anything with Onii-sama without my permission!"
"I—I'm sorry, Yuuka-sama!" Shiina bowed deeply.
"Hey, that's my fault," I tried to explain. "I was the one who—"
Before I could finish, Yuuka grabbed my head and kissed me.
"W-Waaaah..." Shiina gasped.
Yuuka pulled back, her cheeks flushed.
"All of Onii-sama's first times should be mine. I go first—before her."
"Should I take that as a confession?"
She nodded shyly.
"You dummy. It's been obvious from the start. Ever since you saved me... I fell in love with you."
"What about your idol career? Aren't you not allowed to date?"
She sighed and rested her head on my shoulder.
"I'm planning to graduate soon. I've already achieved my dream. Staying in the industry forever isn't for me. The management keeps pushing me to do gravure shoots, but I refuse. I won't sell my body just to stay relevant. Besides—I'm the daughter and heir of Laurier Enterprise. I don't need the money."
"...Okay."
"You should be thankful to have such a loving girlfriend. Lilith told me how you two survived after arriving here. You fed her insects, didn't you?"
"Uuuuugh..."
"Don't worry, Onii-sama. I'm done being an idol. What I want now is to pursue my happiness... and that's becoming your wife."
She smiled sweetly. I leaned in and kissed her this time.
"Onii-sama..."
Our lips locked in a deep, passionate kiss.
When Yuuka finally pulled back, she glanced at Shiina, who looked heartbroken.
"Sorry, Ayaka. Looks like I took his second too~" she grinned.
"Umm... It's fine. I think I'll be going now..."
"Where do you think you're going?" Yuuka raised an eyebrow.
"Eh?"
"It's your turn. Go kiss him already!"
"E-Eh?!"
I turned to Shiina and gently wrapped an arm around her shoulders.
"Wait—I'm not ready—!"
Too late. I leaned in and kissed her, her eyes going wide. She trembled in my arms, but eventually her lips parted and our tongues intertwined. When I pulled away, she was panting softly, her face burning red.
"H-How was it, Ayaka?" Yuuka asked.
"I-It felt... good..." Shiina admitted, flustered.
"Let's sleep together tonight. And leave that pervert here."
Yuuka grabbed Shiina's wrist and pulled her away.
"Wait! What about me?!"
They both turned to me with mischievous smiles. Yuuka whispered something in Shiina's ear, and they nodded in unison.
"No perverts allowed~."

It was morning, and I was the one who made breakfast for my ladies. After giving me a peck on the cheek, they left in a hurry.
"See you later, Onii-sama!"
"Bye, Seir-kun."
"Seir-sama, I'm going now," Lilith said with a bow.
The three of them went to school together, leaving me alone, staring at the crystal ball on the small table.
"Still no news from Naamah..." I sighed.
I was bored out of my mind.
Things were getting intense back in my home world, while here I was—sitting on the couch, staring at the ceiling, doing nothing. The demon realm was in disarray, and the humans from the Empire were doing whatever they pleased near our border. Someone had to fix things before they got worse.
After another sigh, I stood up and decided to head out and wander around the city. Irritated from boredom, I stopped by a café and ordered milk coffee and pancakes from a waitress who looked too scared to even approach me. I hadn't realized it, but my foul mood must've been showing on my face—and my leaking demonic aura gave everyone goosebumps. One by one, the customers rushed out after giving me terrified looks. The waitress returned with my order, trembling as she placed it on the table before running off.
"Tch."
I clicked my tongue, took a sip of my milk coffee, and tried to calm down. While staring out the window, my old flip phone started ringing in my pocket. It was Dad. I didn't want to answer, but it could be something important, so I picked it up.
"Hello?"
...
There was silence on the other end, which only annoyed me further.
"Dad, if you don't have anything to say, I'm—"
Onii-chan?
I froze. That childish voice... My mood flipped instantly, all irritation gone.
"Yes, it's me—your one and only Onii-chan. Why'd you call me all of a sudden? Did you miss me? I miss you too!"
Onii-chan, we're in Hawaii now. The food is delicious!
"Is that so? Do you like it there?"
Yes, Onii-chan!
"Let's all go together next time, as a whole family."
Yes!
She sounded so happy with the idea.
"Huh?"
Suddenly, I heard a strange cracking noise through the call, then a loud ring—and the line went dead.
"...Weird."
Probably just a signal issue, since they were overseas—but I couldn't shake the bad feeling in my chest.
After paying the bill, I stepped outside, but the uneasiness only grew worse. I could feel something off in the air.
"No way... This mana..."
It was strong. A powerful spell was being invoked.
I immediately tried to detect its direction—and realized I was already too late. Looking up, I saw a massive golden magic circle. After a quick analysis, I confirmed it.
"A detection spell?! Shit!"
I bolted toward the school.
"I won't make it in time at this rate!"
Enhancing my speed with magic, I zipped through the streets, surprising everyone as a gust of wind followed in my wake.
"Kyah!"
"Wah!"
A different magic circle hovered above the school, covering the entire building.
"Damn it! They actually dared to cast a large-scale summoning spell?!"
I leapt over the school wall and dashed inside the campus, heading straight for the classroom building.
"Yuuka! Shiina! Lilith!"
Finally, I reached Class 1-A.
"There it is!"
With a powerful roundhouse kick, I shattered the sliding door—stunning the teacher and the entire class.
Bam!
"Yuuka! Shiina! Lilith!"
I shouted as I burst in.
"Hey! What do you think you're doing?! I'm calling security!" the young female teacher snapped.
"Onii-sama?" Yuuka blinked in surprise.
"Seir-sama!" Lilith stood up in alarm.
I breathed a sigh of relief when I saw them safe and smiled.
"Hey, you! Are you even listening to me?!" the teacher shouted again.
She reached out to grab me, but I instantly vanished and reappeared beside Yuuka, gently taking her hand—making her blush.
"Onii-sama?! W-What are you doing?! We're in class!" she stammered, flustered.
"That's it! I'm calling security!" the teacher growled and turned to leave the room—when suddenly, the floor lit up with a magic circle.
"Huh? What's happening?"
"Wait—this spell...!"
Lilith's face went pale.
"It's a summoning spell! Ayaka! Riko! Grab onto Seir-sama—quickly!"
Without hesitation, Shiina dashed to my side and grabbed my arm.
"Eh? What's going on?!" Riko said, confused.
"Just do it!" Lilith yelled, grabbing my coat.
"Ugh, fine!" Riko grumbled and followed suit.
A blinding light swallowed the entire classroom, and we all shut our eyes.

Epilogue
"Onii-sama! Wake up!"
My consciousness slowly returned at the sound of Yuuka's voice echoing through my head. I blinked, my vision blurry, until it cleared and I saw her worried face leaning over me as she shook me gently.
"Finally!" she said with relief.
"Huh...? What happened?" I mumbled, sitting up. That's when I noticed Lilith lying beside me—unconscious.
"Hey, Lilith! Wake up!"
No matter how much I shook her, she wouldn't stir.
Still feeling dizzy from that blinding light earlier—the summoning spell—I quickly realized: we'd been transported to another world.
"Ugh... Yuuka, where are we now?"
I looked around. We were inside a medieval-looking chamber, surrounded by armored soldiers.
"We suddenly appeared here with the whole class," Yuuka explained. "Everyone panicked, and those soldiers started threatening us to follow their orders."
"Seir-kun!"
I looked up and saw Shiina running toward me, with Riko close behind.
"I was so worried, you idiot!" Shiina cried, throwing her arms around me with teary eyes.
"I'm fine, Shiina. I just lost consciousness for a bit."
Riko had a tense expression, so I decided to ask her directly.
"Riko, what's the current situation?"
"A lot happened while you were sleeping like a log over there!" she said, annoyed. "Everyone was panicking!"
"Well... sorry about that."
"It seems we were summoned by that woman over there," Riko added, pointing.
I turned to see a beautiful blonde woman in a white royal gown, surrounded by her vassals. Saeko-sensei—the female teacher—was speaking with her.
"She called herself a princess of some kingdom," Riko continued.
I stood up, cracking my neck and stretching my arms.
"Alright... I think I've recovered—huh?"
I spotted a familiar figure. A girl with long black hair tied in a ponytail, arguing with a massive man in ornate armor. It was Kaho-san. She looked furious, demanding they send us back.
"You girls stay here," I said.
"Where are you going?" Riko asked.
"I'm just going to gather some information."
I walked toward Kaho-san from behind, planning to surprise her.
But just as I reached out to tap her shoulder, she spun around—and my hand missed its mark. Instead, I grabbed something soft... two somethings, to be precise.
"...Seir."
Kaho-san gave me a death glare as I immediately pulled my hands away.
"Do you seriously have time to mess around while we're in a dire situation?"
She was furious.
"S-Sorry..."
Still... now I know how big her chest is.
The high-ranking soldier beside her was glaring at me like I was human garbage.
"A-Anyway, Kaho-san," I stammered, "why did they summon us here?"
The soldier looked confused as I asked.
"They said we were summoned as heroes," Kaho explained calmly. "Heroes to save humanity from the Demon King's army."
"...Huh?"
