The entire Arts Department is filled with extraordinary talents.

The sun was gradually sinking in the west, stretching the shadows of the trees.

In the clubroom of the Literary Arts Club after school, steam slowly drifted from the spout of the hot water kettle.

There were three girls in the room.

Akizuki Yanae leaned her upper body against the desk, the sound of chewing ceaselessly coming from her lips, though no one could tell what she was eating.

"Why is there a purple thread hanging from your mouth?" Rin Tokugawa, reading by the window, asked curiously.

"It's a gummy candy. Rin, do you want some?" Akizuki Yanae pulled a bag of candy from her pocket and offered it, "The book says, carefully chewing tougher foods can help you lose weight."

"...Thanks, but no!" Rin Tokugawa replied, her face pained.

Had no one ever told this fool that eating candy was the exact opposite of losing weight?

"Senpai Kazari, do you want some?" Akizuki Yanae turned to the other girl.

"Ah, no. I can't eat anything right now..." The president of the Literary Arts Club, the fujoshi senior, Kazari Tsukimi, lay despondently across her desk, tearfully complaining to her clubmates: "The BL doujin I stayed up all week to make was confiscated by the student council. Ugh, it hurts so much..."

"It's fine, I already told you—I asked Ms. Shimamoto to get it back for you," Akizuki Yanae comforted her.

"But there's no guarantee. Clearly, Hanashiro is targeting us..."

"Don’t worry, it’ll be fine! Listen, Hanashiro's sister is the new club advisor. Ms. Mikami is familiar with her, and Ms. Shimamoto and Ms. Mikami are best friends. If Shimamoto speaks up, it’ll work out..."

Akizuki Yanae was indeed the top social butterfly, perfectly attuned to the web of relationships in the school.

Rin Tokugawa listened to their conversation, book still cradled in her hands like a freshly peeled bamboo shoot, though her attention drifted.

"Why would your Shimamoto help me?" Kazari Tsukimi wondered.

"It's not really for you—mainly because Kiyoshi's book was confiscated too," Akizuki Yanae chewed her gummy, looking relaxed. "Her favorite student's book was taken by the student council. As soon as I mentioned it, Ms. Shimamoto rushed to demand an explanation."

"Huh? Kiyoshi brings prohibited books? Unbelievable~~" Kazari Tsukimi exclaimed.

The stoic, ascetic, handsome underclassman secretly bringing forbidden books to school...

Was this not the very definition of a wolf in sheep’s clothing?

Kazari Tsukimi’s expression suddenly grew excited.

"Tsk~"

Rin Tokugawa frowned at the window, her disdain clear.

"It’s not really a prohibited book. His sister gave him a romance novel, mainly to cultivate his tastes," Akizuki Yanae leaned back in her chair, lazily chewing her candy.

---

The idea of a sister cultivating her brother's tastes—those words together sounded almost incomprehensible.

"What kind of tastes?" Kazari Tsukimi asked, puzzled.

Yanae spread her hands, speechless: "A little sister obsession..."

"His sister is cultivating a brother complex in him?" Kazari Tsukimi’s brow furrowed. "Is that even Japanese? I don’t think I understand..."

"Strange, weren’t you his ex-girlfriend?" Rin Tokugawa set her book aside and turned. "Are you okay with his sister doing that? Or did it start after you broke up?"

"No, it started long ago. I think since she was in elementary school, she’s been subtly nurturing his tastes..." Akizuki Yanae tapped the table, exasperated.

The other two members exchanged glances.

Each saw shock in the other's eyes.

Kiyoshi’s little sister—truly a legend!

"So, when you were dating him, you never stopped her?" Rin Tokugawa couldn't help but ask.

Akizuki Yanae’s eye twitched, her laughter hollow: "...Ah, haha. O-of course I did. When I was around, his sister didn’t even dare look at him..."

"Really?"

Both girls sent skeptical stares her way.

Of course, it wasn’t true.

In reality, Yanae had fought with all her might and still stood no chance, never even managing to dampen Seiyuki’s enthusiasm.

Seeing her suspicious expression, the others were about to dig deeper and satisfy their gossip when the clubroom door opened and two teachers stepped inside.

One was Shimamoto Yumeko, petite and adorable in a purple dress, not even one meter sixty tall.

The other was a mature, beautiful ice queen, dressed in a standard office lady suit, black stockings and slender heels.

When she entered, the three club members immediately straightened their posture, eyes drifting to the book in her hand.

She was the new librarian this term, the club advisor Hanashiro Mizuki.

Though beautiful, her personality was rather cold, acting swiftly and decisively, giving people the impression she was hard to approach.

"Is Matsudaira here?" Hanashiro Mizuki surveyed the clubroom.

Her voice was clear and cold, as pleasant as a young girl’s, yet tinged with mature magnetism—a rare combination.

"He’s not," Akizuki Yanae stood up. "Is there something you need from him, sensei?"

"This morning’s prohibited items inspection," Hanashiro Mizuki said directly, handing her a book. "Hanashiro wanted me to pass this to him. Although it was confiscated, after checking, there’s no big issue with the content. Please return it to him."

"Okay, thank you, sensei." Akizuki Yanae quickly took the book.

The other two girls sneakily glanced at the cover—"After Marriage, She’s No Longer My Sister—Call Her Wife, Okay?"

"Hiss!"

Both sucked in a cold breath.

Such a little sister—truly terrifying!

"And you, Tsukimi!" Hanashiro Mizuki’s gaze shifted to the bespectacled, twin-tailed fujoshi club president.

"Hello, sensei!" Kazari Tsukimi immediately straightened up.

"What am I to do with you? You’re a third year and still wasting time on these things..." Hanashiro Mizuki’s brows knit, her eyes stern. "Fortunately, it’s homemade, and you can claim it’s for student interest. If you bring store-bought prohibited items to school, it will be much more serious!"

"Sensei, it’s because I’m a third year that I made these," Kazari Tsukimi pressed her hand to her forehead, putting on a dramatic, exhausted expression, "I only drew them to relieve exam stress. I think I’m a victim of society’s endless competition..."

"Enough. Complaints don’t help. Reform and strive for improvement—that’s your only way forward." Hanashiro Mizuki looked at her, expression unwavering. "Tomorrow after school, hand me a written apology and you’ll get your things back. And!"

Her tone rose.

Kazari Tsukimi instinctively looked up at her.

"Take your BL doujin home. Never bring it to school again, and don’t produce any more inappropriate publications here!" Hanashiro Mizuki declared sternly.

"...Understood," Kazari Tsukimi mumbled.

Clearly, she knew she was wrong, but would inevitably repeat her mistake.

Looking at this fujoshi president, then the gluttonous member, and the aloof, cold young lady, and thinking of the yet-unseen Matsudaira Kiyoshi and his legendary sister...

As the club advisor, facing a club full of such extraordinary individuals, Hanashiro Mizuki suddenly felt weary.

"Alright, everything’s settled," Shimamoto Yumeko clapped her hands to draw everyone’s attention. "To celebrate this great moment, everyone, with me—Byzantium—"

"Bang!"

A violent bang on the door abruptly interrupted the zealous homeroom teacher's spell.

"Hey, something terrible’s happened..."

The sexy, glamorous nurse, dressed in a white coat and black stockings, rushed in, addressing the five with urgency: "Kiyoshi’s been taken by the kendo club and is being humiliated..."

In that instant, Yanae’s heart clenched tight.
