Theme: When your voice splits across timelines, which one is still you?
Arc 04 doesn’t begin with a scream.
It begins with a pulse.
One beat.
Out of place.
Out of time.
And then — another.
Rei begins to feel versions of herself unraveling across timelines.
Not just memories.
But melodies.
Not just doubt —
but entire selves that echo through the silence like forgotten songs resurfacing.
This playlist is not about rebellion or awakening.
It’s about fragmentation.
Each track in Arc 04 is a conversation with ghosts.
Not haunting.
But harmonizing.
Sometimes, Rei hears a note and sings it before she realizes it was never hers.
Sometimes, she stops singing —
and another version finishes the phrase.
Pulse Divergence is not a breakdown.
It’s a bleed-through.
Where voice becomes plural.
Where silence is no longer the enemy —
but a mirror of what was never chosen.
She sings with shadows.
She dreams of loops that never ended.
She hears the applause of systems she never escaped.
And through it all, the harmonica begins to tremble —
not in defiance,
but in recognition.
By the final track, Rei no longer asks:
“What did they take from me?”
She begins to ask:
“What am I taking from the other me who never made it this far?”
