The Villainess Wants to Marry a Commoner!! (WN)

From 55 nursery rhymes that have been handed down to date in the Daldanha region of the Gorgonhas continent.
The 54th song ‘Osama no Katara’

There was a bad king on the mountain of Helvandanya

The king came alone on the mountain of Helvandanya

The king doesn’t leave the mountain, but he’s still more knowledgeable than anyone else

The king, with his hands folded, he is still stronger than anyone else

The king doesn’t open his eyelids, but he can see better than anyone else

The king doesn’t speak, but he’s still more attractive than anyone else

There was a bad king on the mountain of Helvandanya

I don’t know what he did, but there was a bad king

One day, a holy knight came from the sky to get rid of the bad king

He divided it into ten kings

On the mountain of Helvandanya, when the strong holy knight returns

He’ll pick up ten kings on the mountain of helvandanya

He went to abandon ten kings across the distant sea

He threw away seven and ate two

There is no bad king on the mountain of Helvandanya

There is no single king on the mountain of Helvandanya

I know it’s short, so I will be updating 2 chapters today.
But I have one very important question.
.
.
What happened to the last king fragment? The song says that the king was divided into ten fragments.
The holy knight threw seven away and ate two.
So where is the other one? Was it left on the mountain? The wording of the song seems to imply that it might be, but at the same time it implies that it isn’t.
But wouldn’t Isabella have to have all ten fragments to become the demon king? So why are there only seven in the game? And what are the other 3 fragments supposed to be? There are only seven deadly sins in real life.

I hope you enjoyed this chapter and thank you for reading!
