> They called her "the Unknown Girl."
> But she had a name.
> Neo had buried it.
> To survive.

### 04:00 – The Recovery Room (Virelia Emergency Wing)
Neo awoke in a collapsed room — screens blinking static, Echo signatures offline.
His vision burned with after-images.
> Hers.
Not her face.
Her **voice**.
A whisper threading through every cell in his body.
And then… he remembered.
---
### Memory Fragment:
> *They were younger.*
> *They sat back-to-back in a concrete cell.*
> *She taught him to fold paper birds out of tissue.*
> *He named every one "hope."*
> "What's your name?" he had asked.
She had looked at him with a sad smile.
> "It used to be **Sana**."
> "Before they stripped it out."
> "Then it still is," he said.
> "I'll remember it for both of us."
---
### 04:10 – Present
Neo whispered it aloud.
> "Sana."
The room shivered.
Outside, lights across the academy blinked once in response — a ripple in the Echo system.
As if it recognized her too.
---
### 04:15 – Sana on the Observation Deck
She stood above the academy.
Alone.
Watching as students tried to reboot Echo servers that would no longer obey.
She murmured:
> "He remembered."
She didn't cry.
But something in the air around her *bent* — like light folding in grief.
---
### 04:20 – Marei's Notebook
In the shadows, Marei read the leaked Echo logs before the collapse. One name was highlighted over and over:
> **SANA [Redacted] — Echo Host Prototype**
> **Linked Subject: T. Mojaki / Subject 17**
> **Result: Mutual Amplification — Terminated**
Marei's hand trembled.
> "So this was never about power."
> "It was about *unfinished memory*."
She circled the word: **mutual**.
Then underlined it twice.
---
### 04:44 – Council Basement (REVERB Division)
Lucid paced furiously.
> "Sana's resonance is activating passive echoes."
> "She's overriding containment fields through… memory imprinting."
A subordinate panicked.
> "Should we shut it all down?"
Lucid paused.
Then whispered:
> "We can't."
> "She *is* the system now."
---
### Final Lines
Neo stood before a broken mirror.
The room reflected a dozen past selves.
But this time, one stood beside him — not an echo.
> "You remembered me," Sana said.
He nodded.
> "And now the system remembers you too."
Together, they stepped into the light.
