The Mirror World did not change.
It never did.
The same empty city.
The same hollow sky.
The same silence pressing down on everything that existed within it.
Saber stood where they had left her.
Unmoved.
Unchanged.
Waiting.
Illya stepped forward.
Not first.
Not rushing.
Just… forward.
Miyu moved beside her.
Rin and Luvia followed.
No one spoke.
There was nothing left to say.
Saber moved.
Immediately.
No warning.
No buildup.
The distance vanished.
Illya reacted.
Faster than before.
She rose into the air, stabilizing mid-motion, forcing herself not to panic as the blade cut through the space she had just occupied.
"Miyu—!"
"I'm here."
Miyu intercepted from the side.
Not attacking.
Disrupting.
Her strike forced Saber to shift angle—not block.
That was enough.
Rin moved next.
A jewel detonated at Saber's flank—
Not to damage.
To force movement.
The explosion pushed Saber half a step off-line.
Luvia struck the moment that shift appeared.
Her attack didn't aim for Saber—
It struck the air around her again.
The barrier flickered.
Visible.
"Now!" Luvia called.
Illya fired.
No hesitation.
No delay.
The beam struck the exposed layer—
Held.
Pressed.
Miyu followed.
Perfect timing.
Her blade hit the exact same point—
A crack.
Larger than before.
Saber adjusted.
Immediately.
Her blade moved—
Not toward Illya.
Toward Miyu.
Miyu twisted.
Barely avoided the strike.
The force still sent her sliding back across the ground.
"Don't stop!" Rin snapped.
Illya didn't.
She held the pressure.
Even as her arms trembled.
Even as the strain built.
The crack widened—
Then—
Sealed.
The barrier restored itself.
Instantly.
Illya's breath hitched.
"…No…"
Saber stepped forward.
Through the attack.
Through the pressure.
Unaffected.
The blade rose again.
Rin intercepted.
This time, she was forced back.
Not much.
But enough.
Luvia clicked her tongue.
"She's adapting."
Miyu moved again.
Different angle.
Different timing.
Sharper.
Her strike landed—
Stopped.
Again.
"…There's no fixed opening," Miyu said.
Rin nodded.
"Because she's creating them as she moves."
Illya's mind raced.
They were doing everything right.
Timing.
Coordination.
Pressure.
And it still wasn't enough.
Saber advanced again.
Step by step.
Shrinking their space.
Controlling the fight.
Illya fired again.
Closer.
More focused.
The result didn't change.
Saber didn't block.
Didn't deflect.
Didn't react.
She moved where the attack wasn't.
Illya's grip tightened.
"…She's not defending…"
Miyu answered quietly.
"She doesn't need to."
Another step.
Closer.
The air felt tighter.
Heavier.
Saber vanished.
Illya's eyes widened.
"Where—"
Too late.
The strike came from below.
She barely raised her wand in time—
Impact.
The force sent her crashing down.
"Miyu!"
Miyu moved instantly.
Intercepted the follow-up strike—
Barely.
Her stance broke.
She slid back again.
Rin stepped in.
Another explosion forced distance.
Silence.
Short.
Heavy.
Illya pushed herself up again.
Slower this time.
Her breathing wasn't steady anymore.
"…We're doing it right," she said.
No one answered.
Because they were.
And it still didn't matter.
Saber stepped forward again.
Unstoppable.
Unchanging.
And for the first time—
Illya felt it clearly.
This wasn't a fight they could win like this.
Illya's breathing didn't steady.
It worsened.
Not from exhaustion alone—
But from the growing certainty that something was wrong.
They moved again.
Not by command.
Not by plan.
By necessity.
Rin struck first.
A jewel detonated in front of Saber—not at her, but ahead of her path. The explosion forced a shift, bending the space Saber would step into.
For a moment—
It worked.
Luvia followed instantly.
Her strike hit the exposed layer of air again, forcing the barrier to reveal itself.
Miyu moved.
Perfect timing.
Perfect angle.
Her blade reached the exact point—
Stopped.
The barrier didn't just block.
It adjusted.
Thickened.
Reinforced exactly where she struck.
Miyu pulled back immediately.
"…It's reacting faster."
Rin didn't argue.
Because she had seen it too.
Illya rose again.
Higher this time.
Trying to gain an angle.
Trying to force something different—
Saber looked up.
That alone was enough.
Illya felt it.
That shift.
That attention.
She fired.
Immediately.
No hesitation.
The beam cut through the air—
And missed.
Not because her aim was wrong.
But because Saber had already moved.
She didn't dodge after the attack.
She wasn't there when it arrived.
Illya froze.
"…How…"
"Stop thinking you're controlling this," Rin snapped.
Too late.
Saber was already moving again.
She closed the distance instantly—
Not toward Illya—
Toward Miyu.
Miyu reacted.
Faster than before.
Better than before.
Still not enough.
Steel met steel—
The force broke her stance.
She held for a second—
Then was pushed back.
Illya moved to support—
Too slow.
The blade shifted direction mid-motion.
Toward her.
Time slowed.
Illya saw it clearly.
Again.
That same moment.
That same realization.
She wasn't fast enough.
Not yet.
Not like this.
The strike came down—
Intercepted.
Rin forced herself between them, a jewel detonating at point-blank range.
The explosion distorted the trajectory just enough—
The blade missed.
Illya dropped again.
Harder this time.
Her body didn't respond immediately.
"…Get up," Rin said.
Not harsh.
Not angry.
Just—
Firm.
Illya forced herself to move.
Her arms trembled as she pushed herself up again.
"…We're not getting closer," she said.
Miyu stood a few meters away.
Her breathing controlled.
Her stance steady.
"…No," she said.
Not frustrated.
Not discouraged.
Just—
Accurate.
Saber stepped forward again.
Slow.
Deliberate.
Unstoppable.
Each step reduced their space.
Each movement forced them to react.
They weren't fighting anymore.
They were surviving.
Illya tightened her grip.
Her mind raced.
Searching.
Thinking.
Trying to find something—
Anything—
There wasn't anything.
Because the problem wasn't their execution.
It was their approach.
Another step.
Closer.
The air tightened again.
Illya felt it.
That pressure.
That inevitability.
"…We can't win like this," she said.
This time—
No one stayed silent.
"…Correct," Rin said.
Illya looked at her.
"Then what do we do?"
Rin didn't answer immediately.
Because Saber was already moving again.
Faster this time.
The blade came from the side—
Miyu intercepted.
Barely.
Her stance broke completely this time.
She was forced back—
And for the first time—
She couldn't recover immediately.
Saber didn't stop.
The follow-up strike was already coming—
Illya moved.
Instinct.
Not thought.
She fired—
Point-blank—
The beam forced Saber to adjust—
Just enough—
Miyu regained footing.
They pulled back.
Distance.
Finally.
But it wasn't enough.
It would never be enough.
Illya's breathing was uneven now.
Her arms felt heavy.
Her movements slower.
She understood it now.
Not emotionally.
Not dramatically.
Logically.
They were losing.
Not because they were weak.
But because—
They were using the wrong kind of power.
Rin exhaled slowly.
"…Now you're starting to see it."
Illya didn't look at her.
"…Then tell me," she said.
Rin's gaze sharpened.
"…You don't need more output."
A pause.
"You need a different answer."
Silence.
Saber stepped forward again.
Closer than before.
And this time—
There was no space left to retreat.
There was no space left.
Illya felt it clearly now.
Behind her—ruins.
In front of her—Saber.
To the sides—nothing she could use.
No angle.
No opening.
No answer.
Saber stepped forward.
One more step—
And it would end.
Illya raised her wand.
Not because it would work.
But because she didn't have anything else.
"…Illya."
Rin's voice cut through the pressure.
Not loud.
Not urgent.
Clear.
"Catch."
Something flew toward her.
Illya's eyes widened.
Her body moved on instinct.
She caught it.
A card.
Different.
She knew it immediately.
It felt—
Heavier.
Not physically.
But—
Present.
Her fingers tightened around it.
"…What is this…?"
Rin didn't look at her.
Her eyes stayed on Saber.
"Your answer," she said.
Saber moved.
Faster than before.
Illya didn't think.
She didn't analyze.
She didn't question—
She held the card tighter.
And for a moment—
Everything else faded.
No sound.
No movement.
No battlefield.
Just—
Weight.
Something settled into her hands.
Not the card.
Something beyond it.
A sensation.
Familiar.
Impossible.
Steel.
She felt it before she saw it.
The shape of something resting in her grip—
Balanced.
Worn.
Used.
A sky.
Endless.
Empty.
Filled with—
Blades.
They weren't falling.
They weren't moving.
They were waiting.
Her breath caught.
"…What is this…"
A voice echoed.
Not loud.
Not distant.
Calm.
Tired.
So this is what you chose.
Illya's grip tightened.
"I didn't—"
The words didn't finish.
Because something else followed.
A feeling.
Not power.
Conviction.
Even if it's wrong…
Her body moved.
Not consciously.
She stepped forward.
And the world returned.
Saber's blade was already descending.
Too fast.
Too close—
Illya didn't raise her wand.
She moved.
Just slightly.
The blade passed beside her.
Missed.
Her eyes widened.
She hadn't reacted.
She had already been in the right place.
"…What…?"
Something formed in her hands.
Not light.
Not mana.
Steel.
Twin blades.
She didn't question them.
She didn't hesitate.
She stepped in.
And struck.
For the first time—
Saber moved to defend.
Steel met steel.
The sound was different.
Sharper.
Cleaner.
Real.
Illya felt it.
The impact.
The weight.
The timing.
And she understood something.
Not with words.
With instinct.
This was how she was supposed to fight.
Saber pushed back.
Harder than before.
But Illya didn't break.
Her stance held.
Barely.
But it held.
Behind her, Rin exhaled slowly.
"…Finally."
Miyu watched.
Silent.
Careful.
Because this—
This was different.
Saber stepped back.
Not retreating.
Adjusting.
Her stance shifted.
For the first time—
She recognized her opponent.
Illya stood there.
Breathing steady.
Grip firm.
Eyes focused.
She didn't understand what she was holding.
She didn't understand what she had stepped into.
But—
She didn't hesitate.
Not anymore.
Saber moved first.
Not faster.
Not stronger.
Just—
Different.
She stepped in.
Blade already in motion.
Illya didn't block.
She shifted.
Half a step to the side.
The strike passed her.
Close enough that she felt the air split beside her shoulder.
Her body moved before thought could catch up.
One blade rose.
Not to meet the strike—
But to guide it.
Steel slid against steel.
The trajectory changed.
Barely.
Just enough.
Her second blade followed.
A counter.
Saber reacted.
Immediately.
The barrier flared—
Illya's strike didn't stop.
It slipped.
Not through.
Between.
The timing was wrong for the barrier.
Or—
Right.
The blade grazed armor.
A shallow hit.
But real.
Saber stepped back.
Not much.
But it was the first time she had given ground.
Illya exhaled.
Slow.
Steady.
She didn't understand it.
But her body did.
Saber adjusted.
Her stance lowered slightly.
Her movements sharpened.
She stepped in again.
Faster this time.
Illya met her.
Not by reacting.
By already being there.
The first strike came—
Redirected.
The second—
Avoided.
The third—
Met directly.
Impact.
The force traveled through her arms.
Into her shoulders.
Through her stance.
She held.
Barely.
Then shifted.
The pressure slid off-line.
She moved inside Saber's reach.
Too close for distance.
Too close for reaction.
Her blade struck.
The barrier flared—
Missed the timing again.
A second hit.
Then a third.
Not stronger.
Faster.
Cleaner.
Each strike landed in the gaps between defense and adjustment.
Saber pulled back.
Illya didn't chase recklessly.
She stepped forward.
Measured.
Controlled.
The fight had changed.
Rin lowered her hand slowly.
"…She's not overpowering it," she muttered.
Luvia smiled faintly.
"…She's reading it."
Miyu said nothing.
She was watching Illya.
Carefully.
Because this—
This wasn't how Illya fought before.
Saber moved again.
This time—
She committed.
A full strike.
Power.
Speed.
Precision.
Everything behind it.
Illya didn't retreat.
She stepped forward.
The blade came down—
She crossed her swords.
Impact.
The force cracked the ground beneath her feet.
Her stance trembled—
Held.
Then—
She shifted.
The pressure slid past her.
She broke the line.
Turned.
And struck.
Directly.
The barrier tried to respond—
Too late.
The blade connected.
Clean.
A crack spread across the invisible layer.
Saber's stance faltered.
For the first time—
A real opening.
Illya saw it.
Didn't hesitate.
Her arm moved—
A weapon formed.
Different from the blades.
Heavier.
Drawn back—
Then released.
The projectile cut through the air—
Twisting—
Bending—
And struck.
The barrier shattered.
Completely.
Saber stood exposed.
For a single moment.
That was enough.
Illya stepped in.
One strike.
Clean.
Precise.
Final.
Silence.
Saber's form broke apart.
The card fell.
The world stilled.
Illya stood there.
Breathing steady.
Blades still in her hands.
She looked down at them.
They felt—
Natural.
Too natural.
"…What was that…?" she whispered.
No one answered immediately.
Rin exhaled slowly.
"…That," she said, "is how you're supposed to fight."
Luvia adjusted her glove.
"…Borrowed, but effective."
Miyu stepped closer.
Her gaze lingered on Illya's hands.
"…You changed," she said quietly.
Illya didn't respond.
Because she didn't understand how.
The blades faded.
Gone.
Like they had never been there.
The card rested in her hand.
Light.
Silent.
And yet—
It felt heavier than anything she had carried before.
That night—
The house was quiet again.
Too quiet.
Illya slept.
Exhausted.
Across the hall—
Her brother stood by the window.
His hand rested against the glass.
His eyes unfocused.
"…Swords…" he murmured.
The word came easier this time.
Not fully remembered.
But closer.
He frowned slightly.
"…Why does that feel… familiar…"
No answer came.
But something had shifted.
Slightly.
Enough.
