05 Is My Little Sister a Teacher?
update icon Updated at 2026/1/3 2:00:03

The Student Council at Valhalla Academy functioned like any high school council, with one key difference: they held authority to discipline students who abused magic. Acting as hall monitors with magical privileges, they could cast spells freely on campus—even using force against ordinary students without consequence. Their power was immense.

Trailing behind the golden-haired beauty, Yan Lingxuan regretted showing off. Why ruin a perfectly good elm tree? Though he’d hastily reattached the broken branch, punishment was inevitable.

Before facing consequences, he allowed himself to admire the view. The girl’s back was even more captivating than her front—her pleated skirt swaying gently with each step, slender waist accentuated by the motion. Sunlight glinted off the smooth skin of her arms and thighs. Her tall frame and wavy, regal hair completed the picture.

*Sherlock Harriet Nanshalit Windsor*

*Age: 16*

*Height: 168cm*

*Measurements: Unknown*

*Ethnicity: Anglo-Saxon*

*School: Valhalla Academy, Grade 10*

*Profile: British royal with third in line to the throne. Arrogant. Disdains men. Suspected lesbian.*

Yan Lingxuan had dug up these details online. Her noble blood was unmatched at Valhalla. "Rich, beautiful, and noble" didn’t suffice—only "noble-beautiful-powerful" captured her essence. Netizens called her "Princess Sherlock," MGI’s top rival to Bai Lingyue with over 100 million followers. Yet such fame likely meant nothing to her pride.

*Walking beside a British princess… should I feel lucky or doomed?*

"Aren’t we heading to the Student Council room?" Yan asked.

The princess ignored him, striding forward without a glance.

*Typical arrogance. The online profile checks out.*

They passed a stone bridge over a babbling stream. Birds chirped amid fragrant blossoms. Hedges and flowers framed the area like a castle garden. Inside a stone pavilion, figures gathered. Only when they neared did Yan spot the sign on the wall: *Student Council Room*.

*Damn. Since when do student councils operate outdoors?*

Closer inspection revealed the "garden" was a hologram—only the real plants and shrubs were genuine.

"Sherlock, back already? Catch the vandal?" A familiar voice called out as they climbed the steps. Its owner’s eyes locked onto Yan.

Moments later.

"Try the Darjeeling oolong—it’s delicious. And help yourself to scones. No need to be shy." Katherine beamed, sliding close to Yan on the bench.

"Thanks, senior." Yan grabbed a scone without hesitation, then lifted his teacup.

"Just call me Katherine. After all we’ve shared, such formality?" She pressed closer. Her fluffy hair carried a sweet scent. The softness of her chest was unmistakable. A sideways glance revealed a tantalizing cleavage above black lace lingerie—and endless pale legs beneath her pleated skirt.

A virgin’s resolve was fragile. Though familiar with her affection, Yan’s heart still raced. He hid behind his scone. With so many watching, he couldn’t expose Katherine’s "sweetheart" act.

Sherlock’s brow furrowed at Yan’s table manners. *Like a monkey.* Worse was watching Katherine dote on this brute. Jealousy flared hot in her chest. Katherine—elegant, powerful, ranked top five in magic—was Sherlock’s idol. Seeing her fawn over Yan felt like betrayal.

"Senior Katherine! Don’t touch that monkey! He’s crawling with fleas! He violated School Rule 6—abusing magic—and Rule 8—destroying property. He’s a criminal! Why treat him kindly?"

*Damn. Calling a stranger "monkey" right off the bat?* Yan bit back retorts. *But why’s she glaring like she wants to skin me alive?* His worry vanished as Katherine’s arms wrapped around him.

"It’s nothing. Just an accident. Let’s forget it happened."

"But—"

*She’s hugging him!* Sherlock’s mind screamed. *Does Senior Katherine truly prefer this monkey?* Yan’s blissful expression ignited murderous thoughts.

"No ‘buts.’" Katherine’s tone turned playful. "What’s gotten into you, Princess? You’re never this petty."

"Ugh…"

That nickname again. *Princess.* Katherine always used it to disarm her.

Unable to sway Katherine, Sherlock redirected her fury at Yan. Lips pressed tight, icy eyes burning—he was the homewrecker stealing her idol’s affection. Yan squirmed between physical delight and lethal glares.

*Reuniting with Katherine here… and she’s Vice President?* After hearing his "crime," she’d magnanimously pardoned him and invited him to tea. *Such noble virtue. I’m in awe.*

"Sherlock, let it go—for my sake." Council President Zhou Jin smiled at Yan.

Zhou Jin: Grade 12. Frail frame—170cm but barely 55kg. Pale complexion, sickly thin. Only his violet necktie stood out.

*Violet tie. Seventh-tier mage. The pinnacle of Valhalla’s magic ranks.*

Yan scanned the others:

Katherine (Grade 11, violet tie, seventh-tier).

Sherlock (Grade 10, indigo tie, sixth-tier).

Isolde Fitt (Grade 10, blue tie, fifth-tier).

Ito Nanaka (Grade 12, indigo tie, sixth-tier).

*All geniuses. No wonder they run the Student Council.*

"Hmph. If you all don’t care, what can I say?" Sherlock shot Yan a venomous look. He remained unrepentant.

"Princess, don’t be mad. Have some tea." Ito Nanaka offered a cup with perfect grace. Sherlock couldn’t stay angry.

"I told you—stop calling me ‘Princess’!"

"Of course. Won’t happen again… Princess."

Sherlock puffed her cheeks in frustration. *Adorably petulant.* Yan stole a glance—and earned an icy glare.

To ease Yan’s tension, Katherine chimed in: "The Council’s quite relaxed. Alice handles all paperwork. We only discipline rule-breakers occasionally. Think of it as an afternoon tea club. You’re always welcome here, Lingxuan."

"Absolutely," Zhou Jin added smoothly. "Anytime for tea, Yan Lingxuan—Bai Lingyue’s brother."

His words stunned the room. Even Sherlock’s gaze sharpened with new wariness.

"Heh, don’t stare so hard. I’ll blush." Yan rubbed his neck, feigning shyness. Sherlock looked ill.

"My sister’s famous, but don’t expect much from her brother. I’ll disappoint you."

"Nonsense, honey. You’re worth anticipating too."

"Since we’re here… tell me about Lingyue’s school life? We’ve been apart ten years."

"Bai Lingyue," Zhou Jin recited effortlessly. "Known as the ‘Silverhaired Violeteyed Sorceress.’ Valhalla’s strongest mage ever. Ace of the Valkyries combat unit. Earned her A-Class Mage rating at age nine—youngest in history. Tops every class, magic exam, and ranking battle. Created twenty-one master-tier spells. Simply put: a genius among geniuses. Untouchable."

Yan’s chest swelled with pride—and shock. *My little sister… achieved all that?*

"Wait, isn’t Lingyue on the Student Council?"

"Not her. She’s far too busy."

"Seven members total. Besides us: Yuta Yan Ye in Grade 10 and Dan Harring in Grade 11. They rarely show up."

*So that shorty’s on the Council too.*

"Honey knows Yuta? Never mention his height—he’ll rage. And trust me, you don’t want him angry."

"I’ve… experienced that firsthand."

Over tea, Yan learned much about his sister. He longed to ask more about the academy and Atlantis—but Katherine’s question jolted him:

"Honey, shouldn’t you be in afternoon magic class?"

"Right! What about you all?"

"Our magic credits are fulfilled. Skipping’s no issue."

*Show-offs,* Yan thought, flipping them a mental middle finger.

As he left, Katherine whispered conspiratorially:

"Others would get in trouble for skipping class… but honey? Lingyue will make an exception for you."

*What does my lateness have to do with Lingyue?* The Council’s knowing nods deepened his confusion.

"One critical matter first," Yan announced gravely. Zhou Jin leaned in.

"Where’s the restroom?"

Lunch, the fanclub ambush, Sherlock’s detention, then gallons of tea… His bladder was bursting.

Atlantis’s tech seamlessly blended into daily life. Thanks to his Wearable Device’s navigation, Yan found his classroom despite unfamiliar corridors.

*(Note: Magic training and regular classes were separate. Mornings covered academics; afternoons focused on magic.)*

General courses followed a uniform teaching method, while magic classes adopted a tailored approach based on aptitude. Thus, students attended magic lessons grouped by their Magic Power proficiency levels, with different classmates each time.

The magic classroom was located on the academy’s north side, inside a massive egg-shaped building.

The moment Yan Lingxuan stepped inside, he felt a dense aura of Magic Power. An unusual sensation enveloped his entire body. He knew he was immersed in magic—though he couldn’t identify its type—and it didn’t seem harmful.

“This must be the classroom,” he murmured.

At the door labeled ‘Introductory Magic Application Class’, his Wearable Device confirmed the destination. With a shy expression, Yan Lingxuan approached. As he neared, the door slid open automatically on both sides. Inside, the entire class turned to look at him.

Though over a hundred students fixed their gazes on him, Yan Lingxuan didn’t glance back. His eyes locked onto Lingyue at the podium.

Her streamlined outfit accentuated her figure, paired with beautiful silver hair and a cold, stunningly beautiful face. Silently, Yan Lingxuan gave his sister a thumbs-up.

“Brother complex,” Su Fangwen sneered from her seat, shooting him her usual disdainful look. Qi Jun, sitting on the other side, also turned toward the newly arrived Yan Lingxuan.

What was going on? Lingyue was the teacher?!

Then Yan Lingxuan recalled her words after lunch: “See you later.” So that’s what she meant!

As he stood frozen, Lingyue spoke sternly:

“Student, you’re late. If you’re late again, be prepared to face punishment.”

“What kind of punishment?” Yan Lingxuan asked with a hint of anticipation.

Later, Yan Lingxuan learned Lingyue wasn’t just Valhalla Academy’s top student, the ace of the Valkyries combat unit, and history’s youngest genius Mage—she was also a magic class teaching assistant.

In the 21st century, the magical world born from the Magic Tide had existed for barely over twenty years. Qualified magic teachers were scarce. Bai Lingyue’s magical studies had long surpassed university level to doctoral standards, naturally qualifying her as a teacher. Yet due to her age, the academy could only appoint her as a ‘teaching assistant’.

Realizing his sister was a teacher also made Yan Lingxuan aware of something else: ‘they’ had never truly understood Atlantis. In fact, they’d been toyed with all along. Getting a tiny bit of data, they thought it was a grand harvest—when really, they were just licking the cold leftovers. This must be the work of Alice, Atlantis’s sole and the world’s strongest AI quantum computer.
