Day One – Foundations Are Lies
Ren learned something important the moment Aizawa threw him.
Not metaphorically.
Literally.
It happened less than five minutes into the internship.
They were on Training Ground Gamma, early morning fog still clinging to the concrete. The city mock-up stood quiet, empty, almost peaceful.
Aizawa didn't greet him.
Didn't explain the schedule.
Didn't even look particularly awake.
He just said, "Attack me."
Ren blinked. "Sensei?"
Aizawa's capture weapon snapped out like a living thing.
Ren reacted on instinct.
Wind surged at his feet, earth reinforcing his stance—
but the scarf wrapped around his ankle mid-motion and yanked.
The world flipped.
Ren hit the ground hard, breath knocked clean out of his lungs.
"Too slow," Aizawa said flatly.
Ren forced himself up, coughing once.
"I didn't even—"
"Think?" Aizawa cut in. "Exactly."
Ren's jaw tightened.
"Again."
This time Ren tried to open distance immediately.
Wind pushed him back, earth cracked beneath his feet—
Aizawa erased his quirk.
Ren didn't realize it until the ground didn't respond.
Until his reinforcement vanished.
Until Aizawa was suddenly inside his reach.
A shoulder check slammed into Ren's chest.
He skidded backward across concrete, barely catching himself before falling.
Aizawa stood over him.
"You rely on your quirk to correct bad positioning," he said. "That's not fighting."
Ren breathed slowly, steadily.
"…Then what is?"
Aizawa's eyes were sharp.
"Survival without permission."
The rest of Day One was hell.
No quirk allowed.
No elemental manipulation.
Just balance drills, grappling basics, stance correction, and relentless repetition.
Ren's muscles screamed.
His instincts failed him over and over.
Every time he hesitated, Aizawa exploited it.
Every time he reacted late, he was already on the ground.
By sunset, Ren could barely lift his arms.
Aizawa watched him struggle to stand.
"Tomorrow," he said, "we start fixing your fear of contact."
Ren swallowed.
"…I'm not afraid."
Aizawa turned away.
"Then you wouldn't avoid it."
Day Two – Contact
Ren woke sore in places he didn't know could ache.
Day Two began with one rule.
"No distance."
Aizawa taped a rough circle on the ground.
"Stay inside," he ordered.
Ren nodded.
Aizawa erased his quirk again.
"Fight."
Ren moved first this time.
He stepped in—not back—trying to remember the stance corrections from yesterday.
Aizawa slipped past his guard effortlessly and hooked Ren's leg.
Down again.
"You flinch," Aizawa said. "Why?"
Ren pushed himself up. "…Because I expect pain."
Aizawa stared at him.
"That's honest," he said. "Good."
They trained like that for hours.
Ren learning to keep his hands up.
Learning to feel weight shifts.
Learning how much force was too much.
Every mistake was punished.
Not cruelly.
Precisely.
By afternoon, Aizawa allowed limited reinforcement—just body strengthening.
No earth. No wind.
Ren tried to use it to tank hits.
Aizawa adjusted.
Strikes aimed for joints.
Leverage over power.
"You reinforce," Aizawa said, twisting Ren's wrist until he tapped out, "but you don't control."
Ren lay on the mat, staring at the sky.
"…I always thought if I was stronger, it wouldn't matter."
Aizawa released him.
"That's the lie most strong people believe."
Day Three – Erasure
Ren hated Erasure by Day Three.
Not because it shut him down—
—but because it showed him exactly how helpless he was without preparation.
Aizawa took him into enclosed spaces.
Hallways.
Stairwells.
Narrow alleys.
"You like open terrain," Aizawa observed.
Ren nodded. "I need room."
"Villains won't give you any."
Aizawa erased his quirk mid-turn.
Ren stumbled.
Aizawa pinned him against a wall in seconds.
Capture scarf tight against his throat—not choking, but controlling.
"You're dead," Aizawa said calmly.
Ren swallowed, heart pounding.
"…Again."
This time Ren didn't rush.
He waited.
Watched Aizawa's shoulders.
Moved when Aizawa moved.
He still lost—but it took longer.
Aizawa nodded once.
That was the highest praise Ren had received all week.
Day Four – Pain Teaches Faster
Ren bruised.
Everywhere.
Day Four focused on pain tolerance and recovery.
Aizawa didn't hold back.
He taught Ren how to fall properly.
How to roll with impact.
How to absorb force without locking joints.
"You can reinforce," Aizawa said, "but you still panic when hit unexpectedly."
Ren clenched his fists.
"I'm working on it."
Aizawa nodded. "I know."
They sparred until Ren's reactions dulled.
Then Aizawa kept going.
Because that's when habits break.
By evening, Ren finally snapped.
"I know I'm bad at this!" he shouted, breathing hard. "That's why I'm here!"
Aizawa didn't yell back.
"You're not bad," he said. "You're incomplete."
Ren froze.
"You built yourself to avoid weakness instead of confronting it," Aizawa continued. "That's not cowardice. It's efficiency taken too far."
Ren exhaled slowly.
"…Can I fix it?"
Aizawa met his gaze.
"Yes. But not quickly."
Day Five – Integration
Aizawa finally allowed controlled quirk usage.
Limited.
Timed.
Purposeful.
Ren learned how to use earth manipulation after contact.
To destabilize footing.
To create openings—not distance.
Wind was restricted to bursts—no sustained control.
"You don't get to float away," Aizawa said. "You reposition."
Ren struggled.
But something clicked.
A grab followed by a sudden ground shift.
A stumble turned into a pin.
It wasn't elegant.
But it worked.
Aizawa watched closely.
"…Better."
Ren smiled for the first time all week.
Day Six – Pressure
Aizawa brought in obstacles.
Multiple opponents—training bots.
Close proximity.
Limited vision.
Ren failed hard at first.
Then adapted.
He stopped reacting.
Started predicting.
Started committing.
By the end of the day, he was exhausted—but standing.
Aizawa spoke quietly.
"You're still not good," he said.
Ren nodded.
"But you're no longer helpless."
That mattered.
Day Seven – Acceptance
The final day was silent.
No drills.
No sparring.
Just conversation.
They sat on a rooftop overlooking U.A.
Ren flexed sore fingers.
"…I used to think power was enough."
Aizawa looked out at the horizon.
"Power is useless if you don't know what to do when it fails."
Ren nodded.
"…Thank you, Sensei."
Aizawa stood.
"Internship's over," he said. "Training isn't."
Ren smiled faintly.
Good.
He didn't want it to be.
Ren didn't leave the week stronger in the way people liked to see.
No new techniques.
No dramatic breakthroughs.
But he left aware.
And awareness, Aizawa knew better than anyone—
was where real strength began.
