I figured out the end of the prophecy

the queen's chariot cannot be stopped (chapter 2)
lord of screen's cleaved red by blade (chapter 3)
the flower man, trapped in asylum (chapter 5)
the angel, banished, meets with its desire (chapter 6?)
AND LAST, WAS THE GIRL. AT LAST, WAS THE GIRL. (chapter 7?)
The last prophecy. The story’s end.
And then. When all hope is lost for the tale.
The final tragedy unveils.
To save the worlds, there is only one way.
THE ANGEL WILL RETURN, AND THE UNDERGROUND WILL GO EMPTY.
Only then, will the worlds be saved. (And these would be the end)
