After school, the siblings were trudging home when Kitsune's damn phone buzzed. She pulled it out, skimmed the message, and flashed that smug-ass grin.
"Yo, Taiyo," she announced, waving her phone like it was her trophy. "Change of plans. My girls just hit me up for karaoke. You're coming with, no fucking excuses."
Taiyo shot her a wary look. "Wait… isn't that gyaru code for a mixer? You know, the kind where boys are all over your shit?"
Kitsune's grin only got wider. "Maybe, maybe not. But they never said you couldn't come—so congrats, little bro. You're officially coming. No bullshit."
At the Karaoke Bar
The second Taiyo stepped into the private karaoke room, and he froze like a deer caught in headlights. This was a total trap.
Kitsune's gyaru crew were already there, having ditched their lame-ass school uniforms for outfits straight out of a bad-girl teen drama—short skirts, crop tops, fishnets… the whole damn package.
"Yo, Kitsune! Taiyo-kun!" one of them hollered, waving a mic like it was a magic wand. "Took you guys long enough, asshole!"
Taiyo immediately ducked behind Kitsune, whispering, "Are we sure this shit is even legal? They look like characters from a sketchy dating sim!"
Kitsune elbowed him hard. "Shut the fuck up before they hear you, dumbass. And stop staring—you're making it way too obvious you're a clueless virgin."
"I AM a clueless virgin!" Taiyo snapped back, his face burning like hell.
"Yeah, and you're fucking advertising it," she shot back with a laugh.
Meanwhile, one of the gyarus wasn't about to let Kitsune keep that boring school uniform on. She tossed her a bag stuffed with some seriously bold clothes.
"C'mon, Kitsune! No way you're keeping that uniform on all night!"
Kitsune pulled out a bedazzled crop top flashing "#BadGirl", a plaid miniskirt, and—she gagged—knee-high fishnets.
"Absolutely fucking not."
"Aww, c'mon, Kitsu-chan!" one of them whined, already dragging her to the changing room. "We can't have you looking like the boring one in the group!"
Meanwhile, Taiyo stood awkwardly in the corner, cursing his life choices.
Then one of the gyarus locked eyes with him and purred, "Hey, Taiyo-kun~. You single?"
Taiyo's brain went into full meltdown. "W-Wait, uh… I mean—"
Before he could finish his pathetic excuse, Kitsune crashed out of the changing room like a damn wrecking ball. She wasn't wearing the new outfit—but that smug, knowing grin said it all.
"Sorry, ladies," she declared, slinging an arm around Taiyo's shoulders. "This one's mine tonight."
The room went silent for a split second.
"Wait, WHAT?!" Taiyo yelped. "Kitsune, what the fuck are you—"
She squeezed his shoulder hard. "Just play along, idiot. Unless you wanna end up as gyaru food."
Realization hit him hard—this was her way of saving his sorry ass from total embarrassment.
Taiyo swallowed, barely managing, "Y-Yeah! That's right! I'm… with her."
The girls erupted in wild squeals.
"OMG, you two are, like, together-together?!"
Kitsune laughed, though there was a dangerous edge in her tone. "Yeah… something like that."
Taiyo mentally braced himself. This night was gonna be a complete shitshow.
The Mixer Games Begin
After a few rounds of karaoke—mostly those wild gyaru pop hits and that painfully awkward solo from Taiyo—the real danger kicked in: mixer party games.
"Alright, time to pair up!" one of the girls announced, clapping her hands.
Taiyo's internal alarms screamed, "Wait, wait, WAIT. Pair up?! With who?! For what?!"
Kitsune just sighed, arms crossed. "Relax, dumbass. They're just doing this to mess with you. Probably."
When Taiyo's turn came, he hesitated, glancing around nervously, his survival instincts screaming in protest.
Then, one of the gyarus—the same one who'd been relentlessly flirting earlier—leaned in with a teasing smile, "Pick me, Taiyo-kun~."
Abort mission.
Before he could say another damn word, Kitsune grabbed his wrist and yanked him back.
"He's already paired up," she announced with a smirk. "With me."
The room exploded with laughter and whistles.
"Aw, Kitsune! You're so fucking possessive over your little bro!"
Kitsune didn't miss a beat. "Of course. Gotta keep you safe from all you horny vultures."
Taiyo was spiraling—he wasn't sure if he should thank her or run straight into traffic.
The Trouble Begins
As the night wore on, the games got even crazier. What started as a few rounds of karaoke soon morphed into a chaotic mix of Truth or Dare, Pocky games, and karaoke challenges that were downright inappropriate.
At one point, a dare had Taiyo singing a love song to Kitsune while locking eyes with her.
"You've gotta be fucking kidding me," he muttered under his breath.
Kitsune smirked, not missing a beat. "What's wrong? Scared of your 'mom'?"
The whole group burst into raucous laughter. Taiyo's face turned beet red as he reluctantly grabbed the mic, his discomfort written all over him.
By the end of the night, as the chaos finally started to settle, Kitsune and Taiyo staggered out of the karaoke bar with barely a shred of dignity left.
"That was the worst fucking night of my life," Taiyo grumbled, completely defeated.
Kitsune ruffled his hair with that classic, teasing tone. "Oh, come on. It wasn't that bad—you survived, didn't you?"
"Barely. And what the hell was that whole 'he's with me' bullshit about?" he shot back.
"I was saving your sorry ass, idiot," Kitsune replied with a grin.
Taiyo sighed, exasperated. "I don't know if I should thank you or strangle you."
"Probably both," she shot back, still grinning. "But hey, we make a pretty good team, don't we?"
Despite everything, Taiyo couldn't help but crack a small smile. "Yeah… I guess we do."
It was around the midpoint of the night that things really spiraled. Taiyo, curled up on a corner of the couch, did his best to avoid the gyaru squad's relentless attention—his brain had already short-circuited more times than he cared to admit. Meanwhile, Kitsune was fully embracing her gyaru persona, laughing, teasing, and jumping into a few of the games.
Then, out of nowhere, one of the girls slid a vibrant, colorful drink over to Kitsune.
"Here, Kitsu-chan! You've gotta try this—it's our special party mix~!"
Kitsune eyed the drink, shrugged, and said, "Why not? Bottoms up!"
Before Taiyo could protest, she downed it in one gulp. "Whew! That's… spicy," she said, blinking rapidly. "But it feels weird too—like it's burning me from the inside."
Taiyo frowned. "Uh, Kitsune, you okay?"
"Yeah, yeah," she waved him off. "Just feeling a bit dizzy. I'll be fine."
When the Chaos Begins
It didn't take long for that drink to kick in. Kitsune, who normally had the energy of a wild-ass tornado, suddenly looked glazed over—as if she was watching paint dry. Her movements slowed to a crawl, her laughter turned a bit too manic, and her gaze… damn, Taiyo couldn't even describe it—it sent shivers down his spine.
Meanwhile, the other gyaru girls were too busy gossiping about the boys to notice a damn thing.
"Taiyo~," Kitsune purred, her voice dropping to a sultry tone that totally caught him off guard.
Taiyo froze. Why the fuck is she saying my name like that?!
"Kitsune?" he asked cautiously. "You alright?"
Leaning in, cheeks flushed, she murmured, "You're, like, really fucking cute, you know that?"
Taiyo's heart nearly skipped a beat. "WHAT?! WHAT THE FUCK ARE YOU TALKING ABOUT?!" he yelped, scrambling back against the couch like he'd seen a ghost.
Kitsune giggled and crawled toward him on all fours—equal parts teasing and predatory. "Don't be shy, little bro. You don't have to hide your feelings."
Inside, Taiyo was screaming—this was NOT normal.
The Gyaru Squad is No Help
The other gyarus noticed the commotion but didn't seem too concerned.
"Aww, Kitsu-chan's so fucking cute when she's drunk," one cooed.
"Yeah, she's just messing with her bro—it's hilarious," another added.
Taiyo was sweating bullets as Kitsune leaned in even closer, her face invading his personal space.
"Hey, Taiyo," she whispered, her warm breath against his ear. "You've been staring at me all night, haven't you?"
"I HAVE NOT!" he shouted, his face turning as red as a tomato. "YOU'RE MY SISTER!"
"But we're not in the damn Isekai anymore," she teased, her grin turning mischievous. "Rules don't fucking matter here, do they?"
Taiyo's brain practically melted—this was worse than any lewd anime he'd ever seen. At least in anime, you could just hit pause.
"Kitsune! Snap out of it!" he pleaded, trying to push her away.
Taiyo's Big Rescue Plan
Realizing his sister wasn't going to stop, Taiyo knew he had to act fast. He spotted a glass of water on the table and, in a moment of desperation, splashed it in her face.
"Gah!" Kitsune sputtered, blinking furiously.
"Sorry! You were acting too weird!" Taiyo said, voice cracking. "You drank something, and it fucked you up!"
One of the gyarus sniped, "Did we make Kitsu-chan too tipsy? Our bad!"
Kitsune groaned, holding her head. "I'm gonna kill you guys later."
Taiyo sighed in relief, helping her sit up. "Thank god you're back to normal. You almost gave me a heart attack."
Kitsune smirked weakly. "What, scared your big sis was about to ruin your whole pathetic virgin life?"
"YES!" Taiyo shouted without hesitation.
"Relax, Taiyo. I wouldn't actually do anything to you—I just love messing with you."
The Aftermath
As the night wound down, Kitsune finally got herself together, though she still glared at the gyaru crew for spiking her drink. Taiyo sat in a corner, his soul barely hanging on.
When they finally left the karaoke bar, Kitsune ruffled his hair with that smug-ass grin.
"Hey, Taiyo?" she said.
"What?" he mumbled.
"Next time, you're buying me breakfast for saving your sorry ass tonight."
"Saving ME?!" he groaned.
"Yup. That's what big sisters are for."
Even though Taiyo's life was an endless trainwreck, he couldn't help but feel a grudging sense of gratitude. As much as his sister drove him nuts, she was still his fucking family.
But as they walked out, an eerie sense of déjà vu crept in—an unsettling familiarity that went deeper than the usual chaos.
"Hey, Kitsune," Taiyo began cautiously, "this might sound weird, but… have you ever felt like you've done something before, even though you haven't?"
Kitsune raised an eyebrow. "You mean, like, déjà vu? Yeah, like when you think you've seen that hot guy twice and then realize it's just your phone wallpaper."
"Not what I meant," Taiyo muttered.
A Fuzzy Memory
The déjà vu only got stronger. Taiyo's brain, usually busy with anime trivia and snack cravings, started dredging up fragments of memories from another world—a world of swords, magic, and an overaffectionate little sister from the Isekai.
"Isekai…" he whispered.
"What?" Kitsune asked, giving him a curious look.
"Nothing!" Taiyo stammered, waving her off. But the memories wouldn't quit.
The Isekai Little Sister
In flashes, he remembered her—a girl with long black hair and sparkling eyes who'd always called him "onii-chan" in that dangerously sweet way. She was caring, obsessive, and way too clingy, turning every day into a challenge.
Every day in that world had been a nightmare of dodging her advances. He'd learned to avoid her hugs, her sneaky hand-holding, and the time she even tried to climb into his bed.
"I'm your little sister!" she'd pouted, as if that justified everything.
"EXACTLY! THAT'S THE PROBLEM!" Taiyo had screamed as he bolted out of the room.
Back in the Present
Taiyo's stomach churned as those memories resurfaced. Was this some cosmic joke? First, he had to deal with an overaffectionate little sister in the Isekai, and now Kitsune was turning into… this!
"Nope, nope, nope," he muttered. "Not happening again."
"What's not happening again?" Kitsune teased. "Another karaoke night with my girls? Because they totally loved you, Taiyo. I mean, you practically have a harem now."
Taiyo froze. "DON'T CALL IT THAT!"
"Oh, come on," Kitsune elbowed him. "You're practically the poster boy for 'accidental player.'"
Taiyo's Desperate Plan
Finally, Taiyo took a deep breath. He needed to shut this down before it spiraled into another catastrophe. "Kitsune," he said, turning serious, "there's something I need to tell you."
Kitsune blinked, surprised by his tone. "What? You finally gonna admit you like me as more than a sister?"
"WHAT?! NO!" Taiyo shouted, his face bright red. "I mean—no offense, but you're my sister! That's fucking gross!"
"Ouch," Kitsune said, feigning a clutch of her heart. "Way to crush a girl's dreams, Taiyo."
"Stop messing around!" he snapped. "I can't get into any of this 'harem' bullshit because…"
He hesitated, the words catching in his throat. Then he decided to go for it. "Because there's someone I like!"
Kitsune's teasing grin faltered. "…What?"
"There's someone I like," Taiyo repeated steadily. "Back in the Isekai, there was a girl who wasn't like the rest. She just… understood me. And I… I think I liked her."
Kitsune stared, her usual playful demeanor softening. "Taiyo…"
The Mood Shift
For a long, silent moment, everything hung in the balance. Even Kitsune seemed at a loss for words. Taiyo braced for more teasing, but instead she just ruffled his hair.
"You're such an idiot," she said softly.
"Hey! What's that supposed to mean?!" Taiyo protested.
"It means you're honest—and kind of sweet in your dumb little brother way."
Taiyo blinked, caught off guard. "Wait… are you… complimenting me?"
"Don't get used to it," she smirked. "But if you've got a girl you like, you'd better treat her right. Otherwise, your big sis will come back and haunt your sorry ass."
Taiyo laughed nervously, scratching his head. "Yeah, sure… thanks, Kitsune."
The Walk to School
As they neared the school gates, Taiyo felt a small weight lift off his shoulders. Maybe coming back to this fucked-up reality wouldn't be so bad after all.
But then Kitsune leaned in close and whispered in his ear, "By the way, don't think I didn't notice you checking out my girls last night. Sweet home, Alabama, huh?"
Taiyo let out a scream that echoed through the courtyard.
