"A pitiful ink-black princess that looked for minds alike who ended up in prison of Paper Kingdom.

But the story didn't end here. Time passed, and Paper Princess herself came to visit the prisoner.

The two became acquaintances shortly after, and Ink Princess was freed from imprisonment.

Ink Princess taught Paper Princess writing, and no paper in the city was blank anymore.

They obtained power known as "knowledge".

Paper Princess couldn't be happier.

Yet, having spent so much time with Ink Princess, she became stained in Ink Princess's pitch-black color.

Day by day, Paper Princess became more and more soaked in jet-black ink...

..until she was indistinguishable from the Ink Princess herself."
