In fact, it was the result of becoming cute with Black Butler. . . .
The evil Queen...
Note that monster is not an adjective here, but a subordinate word.
Her Majesty the Queen was abducted by monsters and brought to another world...
Her Majesty the Queen has been usurped by an evildoer...
Her Majesty the Queen was taken around by monsters and sent around...
Her Majesty, whose personal freedom has never been guaranteed...
The most pitiable Her Majesty in history...
So actually the title should be: Her Majesty the Queen of Monsters
Well, this world is actually crazy
