Jujutsu Kaisen Original Song: Domain Expansion, Domain of Invasion

[Verse]
We built a world on shattered dreams
Concrete jungles and silent screams
Every corner hides a tale
Of broken hearts and souls for sale

[Verse]
City lights they burn so bright
But darkness waits to claim the night
Lost in mazes we can’t see
Our reflection
Shattered
Free

[Chorus]
Domain expansion
Hearts collide
Invasion's here with no place to hide
We fight the shadows with our light
In this war
We'll claim our right

[Verse]
Boundaries stretched
They're wearing thin
Push and pull
We’re drawn right in
Echoes whisper
Time stands still
In this chaos
We find our will

[Bridge]
Hands are reaching
Feel the call
Break the walls
We rise
We fall
United front
We won't deter
In this realm
We conquer

[Chorus]
Domain expansion
Hearts collide
Invasion's here with no place to hide
We fight the shadows with our light
In this war
We'll claim our right

Just a song for an original domain. not sure if it's cannon to JJK or not.
