Chapter 7: The Quiet Guy in Class

My Foreign Girlfriend is a Witch!



Life settled into a bizarre new routine for Yuki Amano, a dual existence that felt increasingly unstable.

By day, he was the quiet computer nerd who was somehow, inexplicably, dating the school’s most beautiful and mysterious transfer student. By night, his world shrank to the green glow of a command line and the smell of ancient paper in the Archive.

He was a ghost in two different machines now, and he wasn't sure which one was more likely to crash first.

He walked down the second-floor hallway, his head down, counting the ceiling tiles. It was a new coping mechanism.

Twelve tiles from the classroom door to the corner. Twenty-six to the stairwell.

It was a simple, repetitive loop that occupied just enough of his RAM to dissociate from the whispers and the pointing fingers. The “Social Shield” Aya had promised was working, in a sense. No one bother him anymore. No one asked him to fix their laptop. They just stared, as if he were a zoo animal that had somehow escaped its enclosure and learned to do calculus.

He turned the corner and nearly collided with Rina Sato.

She flinched, hugging her textbooks to her chest. Her eyes met his for a split second.

Yuki opened his mouth to say something—Hi? Sorry? I miss our raids?—but the words died in his throat.

Rina looked away immediately. A pained expression flashed across her face, quickly replaced by a mask of polite indifference. She offered a tight, small smile that didn't reach her eyes, mumbled a quiet excuse, and hurried past him.

Yuki watched her go. He felt a phantom pain in his chest, like a packet loss in his heart.

Collateral damage, Aya would call it. Necessary sacrifice for operational security.

It didn't feel necessary. It just felt bad.

Fifth period was History of Post-War Economics. The teacher, Mr. Hashimoto, had a voice that could cure insomnia.

Yuki sat in the back row near the window. To the casual observer, he was slacking off. His phone was propped up behind his textbook, playing a ten-minute compilation of kittens falling off furniture.

But Yuki wasn't watching the cats.

His eyes were unfocused, staring through the video. He had run the video file through a steganography filter he’d written last night. By adjusting the alpha channel of specific pixels in every third frame, the video revealed a hidden layer of text—a dense, scrolling document overlaid on the image.

SUBJECT: THAUMATURGICAL RESONANCE AND LEY LINE THEORY
…Western traditions view ley lines as static veins of power (arteria terrae), whereas Eastern traditions view them as flowing currents (ki). This fundamental disagreement leads to incompatibility in warding structures…

It was a crash course Aya had compiled for him. If he was going to be her tech support, he needed to understand the operating system of the universe.

So magic is just APIs that don't talk to each other, Yuki thought, turning a page in his textbook to maintain the illusion of studying. It’s like trying to run Windows software on a Linux kernel without an emulator.

He was so engrossed in the hidden text that he didn't notice his grip on his mechanical pencil loosening. It slipped from his fingers, rolled off the slanted edge of his desk, and clattered loudly onto the polished linoleum floor.

Clack-clack-clack.

Several heads turned. Mr. Hashimoto paused mid-sentence about the Plaza Accord.

Yuki froze, his face heating up. “Sorry,” he whispered.

He bent down to retrieve it. But as his fingers brushed against the floor, another hand reached it first.

The hand was well-groomed, the nails neat. The grip on the pencil was surprisingly firm, with a focused stillness that seemed out of place for a high school student.

Yuki looked up.

Kaito Tanaka was crouching in the aisle next to him.

Kaito was the Golden Boy of Class 2-B. He was the ace of the soccer team, consistently in the top ten for test scores, and possessed a quiet, easy charisma that made him universally liked. He wasn't loud or flashy like the other popular guys. He was grounded. Mature.

He held out the pencil with a warm, genuine smile.

“Here you go, Amano,” Kaito whispered.

“Ah, thanks, Tanaka-san,” Yuki stammered, taking the pencil. He was surprised Kaito even knew his name. To guys like Kaito, guys like Yuki were usually just background textures.

Kaito didn't stand up immediately. He lingered in the crouch, resting his arm on Yuki’s desk. His eyes flicked over to the window seat three rows ahead, where Aya sat. She was staring outside, seemingly lost in thought, her profile a perfect silhouette against the afternoon sun.

Kaito’s gaze returned to Yuki. There was a flicker of something in his eyes—amusement? Curiosity?

“I’ve noticed she’s very observant,” Kaito said softly. “Lefebvre-san. She always seems to be… watching. Does she ever talk about what she sees?”

The question was casual. Friendly. Just guy talk.

But Yuki’s internal firewall threw up a flag.

Why would Kaito ask that? Why observant? Most people commented on Aya’s looks, or her silence. “Observant” was a specific word.

Yuki gripped his pencil tighter. He forced himself to look relaxed. He channeled the “boring, oblivious boyfriend” persona Aya had drilled into him.

“Not really,” Yuki lied, keeping his voice flat. “She’s mostly just… quiet. She likes looking at the clouds. She says the weather patterns in Japan are different from France.”

It was a banal, boring answer.

Kaito studied his face for a second. Then, the easy smile widened.

“Clouds, huh?” Kaito chuckled softly. “That sounds peaceful.”

He stood up, brushing off his knees. He leaned in slightly closer to Yuki.

“You’re a braver man than I am, Amano,” he whispered, a playful glint in his eye. “She seems… intense. Like she could curse you if you forgot an anniversary.”

Yuki forced a nervous laugh. “She’s… not so bad when you get to know her.”

“I’m sure,” Kaito said. “Well, see you around.”

He gave a small, friendly nod and walked back to his seat at the front of the class.

Yuki stared at the back of Kaito’s head. The interaction had been perfectly normal. Friendly, even.

But Yuki felt a cold prickle of sweat on the back of his neck.

He looked down at his phone. The kittens were still falling. The hidden text scrolled on.

…Identification of hostile practitioners often relies on detecting subtle probes. A mundane conversation can be a form of social echolocation…

Yuki swallowed hard. He tapped the screen, closing the video. He didn't feel like studying anymore.

The final bell rang, releasing the students in a chaotic flood of chatter and shuffling feet.

The classroom emptied quickly. Aya remained in her seat, slowly packing her bag. She waited until the last student had left, until the hallway noise faded into a distant hum.

She stood up. The afternoon sun was streaming through the windows, bathing the empty corridor in a heavy, golden light. It was the "Golden Hour," a time when the boundary between the mundane and the magical was naturally thinner.

Aya walked to the door of the classroom. She stopped.

A faint, residual energy signature had been nagging at her senses all afternoon. It was like a stuck pixel on a monitor—barely noticeable, but impossible to ignore once you saw it.

It was weak. But it was persistent. And it was centered right here, near the doorframe.

She glanced up and down the hallway. Empty.

She closed her eyes. She reached out with her mind, finding the thread of aether she kept coiled in her solar plexus.

“Vestigia revelare,” she whispered. Reveal the traces.

She opened her eyes.

The world shifted. The golden sunlight dimmed, replaced by a greyscale overlay.

Spreading out from her feet, a shimmering, silver filigree of light flowed across the floor. It moved like mercury, filling in the microscopic cracks in the linoleum, climbing the walls. It was a diagnostic matrix, highlighting recent magical disturbances.

Most of the hallway was clean. Just the static fuzz of background radiation.

But there, on the wall right next to the door—right where Kaito Tanaka had leaned while waiting for class to start earlier that morning—was a smudge.

It glowed a sickly, pale green.

Aya stepped closer, leaning in to examine it without touching it.

It was a cold signature. Calculated. Mathematical. It wasn't the wild, organic magic of a spirit or a nature witch. It was structured.

A ward, she realized. An observation ward. Someone tagged this classroom.

She reached out a finger to analyze the resonance.

“Lefebvre-san!”

The cheerful voice hit her like a physical slap.

Aya snapped her hand back. She collapsed the spell in a microsecond, the silver world shattering back into golden sunlight. The sudden sensory shift made her dizzy.

She turned, her face instantly arranging itself into a mask of polite disinterest.

A group of four girls was standing at the end of the hall. They were the "Gossip Girls"—Emi-chan and her clique. They were smiling, but their eyes were sharp.

“Hi!” Emi-chan chirped, walking over. “We were just heading to karaoke! A big group is going. You should totally come!”

She hooked her arm through her friend’s. “We’re inviting Amano-kun, too! It would be so cute to have you both there as a couple. We’re dying to see you guys sing a duet!”

The invitation was a trap. Aya analyzed it instantly.

Social Gathering. High Risk. Potential for ridicule. Zero tactical value.

But a flat refusal would be rude. Rudeness attracted attention.

“Thank you for the invitation,” Aya said, her voice soft and accented. “That is very kind. However, I have a… scheduling conflict this evening. Perhaps another time.”

“Aww, really?” Emi-chan pouted. It looked rehearsed. “You’re always so busy! Well, let us know if you change your mind!”

They waved and turned around, walking back down the hall.

Aya stood still. She hadn't fully deactivated the auditory component of her spell. Her hearing was still amplified.

As the girls turned the corner, their whispers floated back to her, clear as a bell ringing in an empty room.

“—God, she’s such a snob,” Emi-chan hissed. “Playing so hard to get.”

“Right? And with Amano of all people,” her friend giggled. “Like, is she stupid? Or blind? She could have anyone.”

“Maybe it’s a kink,” a third girl suggested. “Slumming it with a nerd. Maybe she likes them pathetic.”

Their laughter, sharp and cruel, echoed away.

Aya stood frozen.

She had always known this was part of the mundane world. The petty cruelties. The hierarchy.

But hearing it directed at Yuki… it sparked a sudden, sharp flare of irritation in her chest.

Pathetic? she thought, her eyes narrowing. Yuki Amano cracked a cascade cipher in two hours. He jammed a military-grade magical device with a cell phone. He is a high-value asset.

To judge him on such a flimsy metric as social standing was a gross miscalculation. It was illogical.

And it was… annoying.

Aya clenched her fist. She looked back at the spot on the wall where the green smudge had been. The distraction had cost her the read. The signature had dissipated.

“Failure,” she muttered to herself.

She turned and walked away, her footsteps clicking angrily on the floor.

[POV Shift: Kaito]

The hallway was silent again. The dust motes danced in the fading light.

From the shadowy alcove of a recessed doorway near the stairs, a figure stepped out.

Kaito Tanaka adjusted his bag on his shoulder. The charming, easy-going smile was gone, replaced by a look of cold, predatory focus.

He walked to the spot outside the classroom door. He placed his hand on the wall where Aya had been looking.

He could still feel the echo of her spell. It was faint, but distinct.

Silver resonance, he noted. Structure-based. Analytical.

It confirmed his suspicion.

Western Tradition. Ars Occidentalis.

She had detected his passive ward. She was good. Better than he expected for a student.

He pulled out his phone. He opened a secure messaging app that looked like a calculator. He typed a code: 55378008. The interface shifted to black and red.

He typed a message.

To: Handler
From: Operative K

Target Alpha (Lefebvre) confirmed. Practitioner of Western Arts. Skill level: High. She detected the passive observation ward.

Target Beta (Amano) is a non-threat. Confirmed mundane. Likely under a charm or acting as an unknowing mule. He is oblivious.

Continuing passive surveillance. Do not engage yet. Let them feel safe.

He hit send.

Kaito pocketed his phone. He looked down the hallway where Yuki and Aya had gone.

A slow smile spread across his face. But this time, it didn't reach his eyes.

“Brave man, Amano,” he whispered to the empty air. “Very brave.”

He turned and walked away, whistling a cheerful tune.
