"...Why do they want that mad king to live?"
Arsene couldn't understand: "Is it just because they don't want him to become a god? Even if the mad king achieves the Heavenly Department position, what would he do then? Would he exile all the Sons of the Moon?"
But during the Swan King's reign, the Sons of the Moon always stayed low-key.
There were too many of the nobles who weren't truly human, so much so that even the Sons of the Moon became anthropomorphized.
At that time, it was absolutely unlikely for the Swan King to have such bizarre needs. It could even be said that the Sons of the Moon and the Swan King were almost in the same camp—at least, they both needed those nobles to scram. If the Sons of the Moon ascended, they were at least willing to follow the Swan King's orders and wouldn't publicly assassinate him.
