Tokiwadai Middle School had two dormitories—one located within the School Garden and the other outside it, officially known as "Tokiwadai Middle School District 7 Student Dormitory."
Misaka Mikoto and Shirai Kuroko lived in the dormitory outside the School Garden, while Selene's luxurious residence was within it.
Given Tokiwadai's educational standards and refined training environment, its students were expected to be graceful, composed young ladies. Yet, as with any educational system, there were always a few "exceptions." Tokiwadai was no different—it too had its... failed cases.
"Onee-sama~!"
"Ugh..."
"Though they're supposed to be soft, your chest is still too flat, Onee-sama! Ah~! This modest yet sinful allure... Kuroko can no longer resist~ my heart... is surrendering~!"
"GET OUT!!!"
"Pff—ah~!"
To the other students in the dormitory bathroom, this was nothing unusual. Such scenes had become a daily spectacle over the past month.
Although Shirai Kuroko normally appeared proper and composed, something about Misaka Mikoto turned her into a complete pervert. Perhaps... it was fate's version of true love.
Without hesitation, Misaka kicked the tea-red twin-tailed girl who was groping her from head to toe, sending her flying.
"You were born broken!"
...
Though her plans had a few hiccups (such as missing computer parts), Shirai Kuroko still remembered today's special occasion. "Today marks a very important anniversary for Kuroko and Onee-sama..."
In the middle of the day, inside her dorm room, Kuroko sat at her vanity—wearing deep purple lipstick and a scandalously revealing magenta outfit. Her entire presence radiated seduction. If anyone from Anti-Skill walked in now, she'd be arrested for indecent exposure without question.
Click.
The sound of the door unlocking reached her ears. The moment the door opened, Kuroko leapt forward with all her passion.
"Onee-sama~!"
In midair, she even tried to pose alluringly, twisting her body so that her outfit revealed as much skin as possible...
Completely unaware of the three people standing behind Misaka Mikoto.
"Sorry to intrude..."
"...Yeah."
...
Eh?!
...
THUD!
Moments later, a thoroughly beaten Kuroko sat obediently on the floor, now properly dressed in her Tokiwadai uniform once more.
"Seriously, what were you thinking?" Misaka scolded, rubbing her temple.
"More importantly, Onee-sama—why are Uiharu and Saten here? And even Selene-senpai too?"
"We just happened to run into each other downtown. After hanging out at the arcade, I invited them to tag along while I went shopping. Uiharu said she wanted to see my dorm, so we all came together."
After Misaka's explanation, everyone sat down on the bed.
Meanwhile, Kuroko lay on her stomach, pouting miserably with her hands under her chin and her hips raised—not the most modest position.
"It's amazing, though," Uiharu Kazari said, her eyes sparkling with admiration. "Tokiwadai's dorms are incredible. I'm so jealous, right, Saten-san?"
"Yeah, even the cafeteria nearby is huge," Saten Ruiko agreed. The gap in facilities between schools really was staggering.
She used to resent Tokiwadai, but after getting to know its students up close, most of that resentment had faded. In fact, she even began to daydream about what it might be like to attend Tokiwadai herself.
"This is my first time in a Tokiwadai dorm," Selene remarked with curiosity. "So this is what a double room looks like."
"Huh? You don't live here, Selene-senpai?" Uiharu asked in surprise.
"No. Tokiwadai has two dorms—this one, and another inside the School Garden."
"Wow, the School Garden dorm! I've heard it's shared by five of the top schools in Academy City! I'd love to see it someday!"
"Then it's settled," Selene said with a small smile. "Sometime soon, I'll invite you all to visit my place. It's quite spacious, and I'll give you a tour of the School Garden while we're at it."
"Really?" Uiharu's eyes sparkled with excitement, her expression full of awe.
"Haha~ it's no big deal. If you ever want to visit, just tell me—"
In the middle of the cheerful conversation, Misaka suddenly froze, her expression turning wary as she noticed Kuroko's heavy, excited breathing beside her.
Although she wasn't pulling any new perverted stunts, Shirai Kuroko's constant rolling around on the bed was enough to make Misaka Mikoto uncomfortable—especially since this was her bed, and there were guests in the dorm today.
"...Kuroko, what are you doing now?"
"N-nothing! Ahem~! Since there's not much to offer, please make yourselves at home!" For some reason, Kuroko suddenly sat up straight, her eyes unfocused and dreamy, slowly inching her way toward Misaka with a lovestruck expression.
"Hm?" Following Kuroko's shifting gaze, she froze as she realized what Saten Ruiko was doing under her bed. "Saten-san, what are you doing down there?"
Saten pulled out a rectangular box. "Nothing much! It's just standard procedure when you visit a friend's home—to conduct a little... search. Whoa!"
As she rummaged through it, she suddenly pulled out a black, gold-trimmed triangular pair of panties. Her cheeks flushed slightly as she exclaimed, "So sexy!"
"S-Saten-san, you really shouldn't be going through someone's things like that..." Uiharu stammered nervously.
Naturally, Saten assumed they belonged to Misaka Mikoto. "As expected of Misaka-senpai! So mature!"
"No... that's—"
"They're mine," Kuroko said boldly.
The room instantly fell silent.
"Kuroko's...?" Uiharu Kazari stared in shock, her mouth agape, completely unprepared for such a revelation.
"So... daring?!" Saten's voice trembled in awe.
Selene, however, wasn't surprised in the slightest. She knew this was nowhere near Kuroko's limit.
Kuroko calmly twirled a strand of hair around her finger, radiating smug self-confidence. (And thus began Kuroko's Pervert Lecture 101.)
"It's not that bold, really. Every lady should own at least one pair of black panties."
"Then... this red butterfly-patterned one?"
"For days when I want to feel... fiery."
"And this tiny T-back thong?"
"That's a treasure that leaves no marks on the skin."
"And this full-body sheer bodysuit?!"
"There are times when a lady simply must display her beauty."
...
For a first-year middle schooler, her level of "mature taste" was staggering. Everyone in the room was frozen in place—including Selene. Knowing about Kuroko's eccentricities was one thing; seeing them firsthand was another. Especially since Selene herself, aside from Tokiwadai's short skirts and her personal preference for tights—looked absolutely modest in every other way.
Regaining her senses, Saten Ruiko suddenly lifted Uiharu Kazari's skirt as if to calm herself down.
"Wah! Saten-san, what are you doing all of a sudden?!"
"Nothing! I just... needed to remind myself what normal life looks like. Seeing your striped panties helped me feel grounded again."
"Uuu..."
Lowering the skirt, Saten nodded in relief. Finally, she felt she'd returned from a dangerous realm.
Granted, Kuroko's teleportation ability required her to wear light clothing—but these kinds of "adult" undergarments being her standard attire was... well, something else entirely.
"What's so shocking about a few undergarments? I've got plenty more," Kuroko said, sighing dramatically at everyone's prudishness. Then she began showing off her "collection."
"Look—transparent bras with flowing lace trim... garter sets with delicate ribbons... and this one—"
After producing two more scandalous pieces, she suddenly pulled out a completely pink, cartoon-patterned pair of children's underwear.
At that, Uiharu and Saten both sighed in relief.
"Thank goodness. So Kuroko still wears normal ones sometimes. My Kuroko's back."
But Kuroko froze, realizing what she had just exposed.
Misaka's face turned bright red as she swiftly snatched the underwear and held it to her chest. "Sorry, that one's mine."
Then her expression darkened. "So, Kuroko! That means you did take my panties!"
Before Kuroko could even explain, Misaka grabbed her by the cheeks and started pulling and stretching them mercilessly, like kneading dough.
"Forgive me, Onee-sama!"
Seeing the chaos unfold, Saten and Uiharu rushed in to defuse the situation—suggesting they look through Misaka's photo album instead. It was a temporary rescue for Kuroko.
But Selene knew better. This was merely the calm before Misaka Mikoto's next storm.
After looking through Misaka's photo album, everyone turned their gaze toward Shirai Kuroko. However, she immediately declared that she was a woman who lived for the present—she didn't need a photo album.
"I'm different from the rest of you. Kuroko is a woman who lives in the moment. Rather than dwelling on the past or dreaming of the future, I choose to cherish the here and now. I've already decided that in my heart..."
Though she sounded poetic, such words were no match for "script examiner" Saten Ruiko. Under Kuroko's horrified stare, she gasped, "No!!! Don't—!"
But it was too late. Saten had already pulled a secret book from the bottom of the shelf—its cover marked boldly with the word "Secret," as if daring people to open it.
"No!! Not that one!"
"Ah~"
"Whoa~"
Taking the "secret" book, Selene flipped it open—and was immediately greeted by a collection of Misaka Mikoto's most private candid photos. She couldn't help but sigh. This girl really is a textbook pervert.
In the original story, such a photo album might've been implied—but here, the evidence was literal. Each page revealed new angles, close-ups, and "artistic shots" of Misaka. Selene was honestly impressed—and disturbed enough to remember it for a year.
"Kuroko!!!"
Face blazing red, Misaka erupted in fury. She caught the fleeing Kuroko and began pulling at her cheeks once more. "You're right—you really should be reflecting on the present moment!"
"I-I'm sorry, Onee-sama!"
Collapsing dramatically onto the floor, Kuroko covered her face and sniffled as if wiping tears away. "I... I just love Onee-sama so much... You've forgotten what today is, haven't you? I thought bringing Uiharu, Saten, and Selene-senpai along was part of your plan for today!"
"Today?" Misaka blinked, confused. "Now that you mention it..."
"Remember now?" Kuroko asked, eyes sparkling with hope.
"...It's the one-week anniversary of when I met Uiharu and Saten, isn't it? Right, Selene?"
Crack. A faint sound of breaking echoed through the air.
"Misaka-san, I've known them far longer than you have," Selene remarked dryly.
"Who cares. You've all known each other for about a week—so let's call it a one-week anniversary!" Misaka said cheerfully.
"That's fine by me! I'll treat everyone to dinner tonight," Selene added.
"Yay!" the others cheered.
Meanwhile, Kuroko sat motionless, her entire body metaphorically cracking apart like a shattered statue. They completely forgot me... Her eyes dulled, filled with despair.
Sitting alone in the corner, she muttered, "This... this difference in treatment... Even Selene-senpai too... Am I just a child nobody wants?"
She clutched a can of red bean soup, staring at the single bean stuck near the opening. "This poor red bean—nobody will eat it. It'll just be thrown away. I'm just like this lonely little red bean!"
Glug glug!
Glug glug!!
Glug glug!!!
"Ugh, you've been doing that nonstop," Misaka groaned.
Crushing her empty can flat, she turned to glare at Kuroko. The twin-tailed girl's expression was pitiful—like a resentful wife abandoned by her husband. "I'm just... drinking red bean soup," she said with a jealous tone.
"Um..."
"Of course I'm jealous! 'One-week anniversary'? Don't make me laugh. Today marks one month since the fateful day when Onee-sama and I were bound by destiny's red thread. One month ago—"
"Stop! Stop right there!" Misaka interrupted before she could continue. "You forced your way into my room that day! It wasn't fate, and it definitely wasn't a red thread! And what's all this about joy, sorrow, and red bean soup?!"
The air grew tense. The jealous aura vanished, replaced by pure panic. Sweat began trickling down Kuroko's forehead. "Uh... I just remembered—I have something urgent to do..."
"How can you even say that!" Misaka grabbed her again, stretching her face with both hands. "You pervert! You need to be purified!"
"W-wait! It's just... a difference in perspective! I just wanted... to celebrate this special day with you, Onee-sama—"
Ding-dong!
The doorbell rang, cutting her off.
"Delivery for Room 208. Is there a Shirai Kuroko here?"
Kuroko froze in place, her body stiff as a board. Misaka frowned suspiciously and walked to the door to speak with the courier.
"Yes, that's us. What's the package?"
"Computer parts," the deliveryman replied.
Kuroko immediately relaxed with a sigh of relief. Oh, right... that must be it. The company's staff know what they're doing, after all.
"And who's the sender?" Misaka asked casually.
The courier, without hesitation, read the label aloud. "From [Love & Herbal Aphrodisiac Co., Ltd.]."
"AAAAAAAHHHHHH!!!"
