The word *erosion* stayed in her mind.
Not like a thought.
Like a crack that refused to close.
Zangetsu Sakura walked faster than she intended.
Not because she knew where she was going.
But because standing still felt worse.
The ring in her hand was no longer just warm.
It felt… responsive.
Like it reacted faintly when her thoughts turned toward Haruto.
"…that's impossible," she whispered.
But nothing about this situation cared about what was impossible.
---
She stopped near a pedestrian bridge.
Below, water moved steadily.
Unbothered.
Unchanged.
Unlike her.
Sakura leaned slightly on the railing.
Trying to steady her breathing.
"…if this is real…"
Her voice lowered.
"…then why does it feel like the world is pretending it isn't?"
No answer came.
But something *shifted* behind her.
---
A faint fracture in the air.
Not visible to most people.
But she felt it immediately.
Her body reacted before her mind did.
Sakura turned sharply.
"…who's there?"
Nothing.
Just people walking.
Just noise continuing.
But the feeling didn't leave.
It stayed.
Watching.
---
Then—
her phone vibrated again.
Sakura flinched slightly this time.
Unknown number.
But she already knew.
Her thumb hesitated.
Then answered.
"…stop doing this," she said immediately.
Silence.
Then—
a soft laugh.
Barely there.
Familiar in a way that made her chest tighten.
"…you're adapting faster than expected."
Sakura's grip tightened.
"…who are you?"
A pause.
Longer this time.
Then—
"…someone who remembers what you're starting to forget."
Her breath caught.
"…I'm not forgetting anything."
Another pause.
Then the voice softened.
"…that's what makes it dangerous."
---
Sakura stepped away from the railing.
Her heart beating unevenly now.
"…what do you mean dangerous?"
The voice didn't answer immediately.
Instead—
"…tell me," it said quietly.
"…what's his name?"
Sakura froze.
The air around her felt suddenly heavier.
"…Haruto," she said firmly.
No hesitation.
No doubt.
---
Silence.
Longer than before.
Then—
"…good."
Her fingers tightened around the ring instinctively.
"…what is this?" she demanded.
"…why do I feel like everything disappears when I try to remember him?"
The voice didn't respond directly.
Instead—
"…because the world doesn't allow continuity."
Sakura frowned.
"…that makes no sense."
"…it doesn't have to," the voice replied.
"…it just has to happen."
---
A sudden noise cut through the call.
Static.
Sharp.
Unnatural.
Sakura pulled the phone away slightly.
"…wait—!"
But the voice rushed through one last sentence.
Faster.
Lower.
"…if you want to keep him—don't stop remembering."
Then—
the line died.
---
Sakura stood frozen.
"…keep him…" she repeated softly.
The words felt heavier than anything else so far.
Like they weren't just instructions.
But a warning.
Or a rule.
---
She looked down at the ring again.
And for the first time—
she noticed something new.
A faint marking inside it.
Barely visible.
Almost erased.
But there.
Her breath stopped.
"…there was writing here…"
Her fingers traced it carefully.
And as she focused—
the letters *almost* formed.
Almost became readable.
Almost became real.
But something pushed back.
Like the world itself resisted her seeing it.
---
Sakura stepped back suddenly.
"…no…"
Her hand trembled slightly.
"…this is not just memory loss…"
She looked up at the sky.
At the street.
At everything that looked normal but wasn't.
"…there is definitely something much more to this," she whispered.
---
And somewhere—
deep inside the fracture of reality itself—
something responded.
Not with words.
Not with sound.
But with certainty.
As if her conclusion had just made everything harder to contain.
---
And for the first time—
Sakura felt it clearly.
Not confusion.
Not sadness.
But pressure.
Like something was trying to fully break through…
before she was ready to confront it.
