Flames are darkness.
They symbolize pain. The brighter the flames burn, the deeper the darkness grows.
And every pain must accompany the existence of flames. They are witnesses and participants, using human suffering as fuel, burning until the end of memory.
The girl known as [Black Rock Shooter] awakens from reincarnation and gains the power to transmigrate between dimensional worlds.
