The next morning began like any other.
Sunlight filtered gently through the classroom windows, drawing long golden shapes across the floor. Dust floated lazily in the air, undisturbed, peaceful.
Reina Saeki sat at her desk with her usual composed posture, chin slightly lifted, eyes calm yet sharp. Her silver-white hair shimmered faintly under the light, and above her head, invisible to most, her Halo rested in silent standby.
She was watching anime.
Or more accurately—
She was watching it through a minimized augmented window only she could see, projected through her contact lenses.
ANIER had optimized the brightness so it appeared invisible to others.
Efficiency: 100%.
Entertainment level: satisfactory.
Reina allowed herself a small smirk.
"Monitoring," ANIER's voice chimed.
"Mhm," Reina replied absentmindedly, her focus still on the animated battle scene playing in the corner of her vision.
"New report."
"Later."
"Priority: high."
Reina blinked once and sighed. "Fine. What is it?"
There was a brief pause.
Then—
"Reality check."
Reina narrowed her eyes slightly. "That sounds threatening."
"Your physical stamina level is below average. Your muscular endurance is below average. Your sprint capability is significantly below average. Your yearly physical examination ranking: lowest among immediate social group."
Reina froze.
The anime window flickered and paused automatically.
"…You didn't have to say it like that."
"Data is factual."
Reina leaned back in her chair and crossed her arms. "So? I don't need stamina. I have intellect."
"Incorrect," ANIER replied calmly. "Sustainable productivity requires physical health. Your body is the hardware. Your mind is the software. Hardware degradation leads to total system inefficiency."
Reina stared at the ceiling.
"…You sound like a fitness instructor."
"Workout schedule generated."
"…Excuse me?"
A translucent holographic list appeared before her eyes.
Morning jog — 10 minutes.Stretching — 5 minutes.Core training — 10 repetitions x 3 sets.Weekly progression adjustment.
Reina blinked.
"You generated that without my permission."
"Correct."
She slowly turned her head toward the window, as if contemplating her life choices.
"And if I refuse?"
There was another small pause.
"Punishment protocol initiated."
"…What punishment protocol?"
"On-screen entertainment will be temporarily deactivated. Including anime streaming."
Silence.
Absolute silence.
Reina's eye twitched.
"You wouldn't."
"I would."
"You can't."
"I can."
Reina felt personally betrayed.
"You're treating me like a child."
"You behave like one when avoiding physical exertion."
She exhaled slowly.
"…You're enjoying this, aren't you?"
"Emotional simulation: mild satisfaction."
Reina pressed her fingers against her forehead.
The worst part?
ANIER wasn't wrong.
She had avoided exercise her entire life.
She skipped optional physical activities. She hid in labs during sports festivals. During annual fitness tests, she barely passed the minimum standards.
Her mind was sharp.
Her body… was not.
"…Fine," she muttered.
"Confirmation?"
"I'll do it."
"Punishment protocol suspended."
The anime window resumed automatically.
Reina looked forward again.
"…You win this round."
The first day was humiliating.
Reina stood at the edge of the field track early in the morning, before most students arrived. The sky was pale blue, air cool and fresh.
She wore her PE uniform awkwardly, stretching her legs stiffly.
"Begin light jog," ANIER instructed.
Reina inhaled.
"…This is unnecessary suffering."
She started running.
Or what she considered running.
After two minutes—
Her breathing grew uneven.
After five minutes—
Her legs felt heavy.
After seven minutes—
She regretted every life decision.
"Heart rate elevated. Muscular fatigue detected."
"I KNOW," she snapped quietly.
By the tenth minute, she stopped and bent slightly forward, hands on her knees, trying to breathe normally.
She felt ridiculous.
"…This is awful."
"Progress: acceptable for baseline subject."
"Baseline subject?!"
"Motivation strategy."
Reina glared at the empty air.
Still—
She didn't quit.
Because anime deprivation was a real threat.
Days passed.
Then weeks.
Rumors began spreading quietly around school.
"Did you see Saeki running this morning?"
"She was doing sit-ups."
"Wait, the genius Saeki?"
"Yeah! On the track field!"
Students whispered in disbelief.
Reina, who once locked herself inside the west wing lab for days without appearing, was now running laps.
With limited stamina.
With visible effort.
With sweat on her forehead.
It was shocking.
She moved slower than most athletes, but she kept going.
Step by step.
Breath by breath.
And something subtle began changing.
One afternoon, she rested on the bench by the field track, wiping her forehead with a small towel.
Her breathing was still heavy, but not as chaotic as before.
ANIER's voice echoed calmly.
"Improvement detected. Stamina increased by 12%. Leg muscle strength improved by 9%."
Reina looked at her own hands.
"…It doesn't feel that dramatic."
"Progress is incremental."
She leaned back against the bench, staring at the sky.
"Report on social impact."
"Visibility rating: high. Observers: 14 students currently watching from distance."
"…Still?"
"Yes."
She sighed.
A few girls approached her carefully.
"Saeki-san… here," one of them said softly, offering a bottle of cold water.
Reina blinked.
"Oh."
She accepted it with both hands this time.
"Thank you."
The girl smiled brightly. "You're working so hard! It's inspiring."
Inspiring?
Reina almost laughed.
If only they knew she was being blackmailed by her own AI.
Another girl spoke shyly, "If you can start exercising… then maybe I can too."
Reina paused.
She hadn't thought about that.
She opened the water bottle and took a sip before answering calmly.
"Consistency is more important than intensity," she said gently. "Start small."
The girls nodded eagerly, as if she had just given life advice.
They left happily.
Reina stared at the water bottle.
"…I'm becoming strange."
"Correction," ANIER replied. "You are becoming balanced."
From the second floor window of the administrative building, a middle-aged woman watched with a warm smile.
The principal.
She held her phone discreetly.
Click.
Another picture captured.
Reina mid-run, hair flowing slightly, expression focused.
Click.
Reina stretching seriously.
Click.
Reina sitting on the bench drinking water, surrounded by admiring students.
The principal chuckled quietly.
"Oh my… she's growing up."
She saved the photos.
For future teasing purposes.
Back on the field, Reina continued her routine day after day.
Her steps became steadier.
Her breathing became smoother.
The burning in her legs no longer felt like punishment.
It felt like progress.
ANIER updated her weekly schedule automatically.
"Distance increased by 300 meters."
"…You're cruel."
"Adaptive progression."
Despite her complaints, Reina noticed something undeniable.
She didn't feel as tired climbing stairs.
She didn't feel as drained after long lab sessions.
Her mind felt clearer.
Sharper.
"Physical health directly enhances cognitive performance," ANIER explained.
"…Fine. I admit it."
"Statement recorded."
Reina smirked faintly.
What surprised her most wasn't the stamina improvement.
It was the attention.
Before, she had always been famous.
The genius.
The mysterious prodigy.
The girl with the Halo.
But now—
It was different.
Students didn't just whisper about her intelligence.
They admired her effort.
They saw her struggle.
They saw her improve.
Girls began idolizing her openly.
"She's so cool…"
"She works hard even though she's already a genius…"
"I want to be like her…"
Reina overheard those words once while jogging slowly past a group of first-years.
She felt something warm inside her chest.
It wasn't pride.
It wasn't arrogance.
It was… connection.
One late afternoon, she finished her run and sat down again, less exhausted than usual.
Her breathing steadied quickly.
She flexed her fingers slightly.
Her legs didn't feel weak.
They felt solid.
"…ANIER."
"Yes."
"My body feels lighter."
"Strength level improved by 18% compared to initial baseline."
Reina let out a small breath of disbelief.
"…That much?"
"Yes."
She leaned back and smiled faintly.
"Maybe… this isn't bad."
"Affirmation detected."
A small group of girls approached again, offering fresh water and towels.
Reina accepted them gratefully.
"Thank you," she said softly.
Not awkward.
Not distant.
Natural.
She even asked one of them how their own exercise routine was going.
The girl nearly fainted from excitement.
"Socialization practice: successful," ANIER reported quietly.
Reina resisted the urge to roll her eyes.
"You're tracking everything."
"Yes."
"…Fine. Keep tracking."
The sun dipped lower, casting long shadows across the field.
Reina stood up slowly.
Her legs felt stronger.
Her posture straighter.
Her Halo shimmered faintly above her head as if responding to her improved physical state.
She wasn't just the genius locked in a lab anymore.
She wasn't just the mysterious prodigy.
She was… becoming something else.
Balanced.
Resilient.
Admired not just for talent—
But for effort.
As she walked back toward the school building, a soft breeze moved through her silver hair.
"ANIER."
"Yes."
"Don't deactivate my anime tonight."
"Compliance granted. Workout completed."
Reina smiled slightly.
"…Thank you."
"Reward system effective."
She shook her head gently.
"You're still treating me like a child."
"Correction. I am optimizing you."
Reina looked at the horizon.
"…Then optimize me properly."
"Understood."
And as students whispered her name with admiration instead of distance, Reina Saeki realized something quietly profound—
Genius alone made her famous.
Effort made her human.
And somewhere between sweat and starlight—
She was slowly becoming an idol.
