Maggie

She is also one of the daughters of Karl Rio. There were many other girls like them in the castle, but they didn't have high status. The baron did not really care about those girls.

Background
Maggie came from a poor relative, and she came seeking help from the Rio Family; Maggie's family declined a long time ago.

Maggie's life was easy. Her parents worked for the baron in the castle, and they could easily get some money to survive. They were just like regular workers in the castle, maybe they were even treated a bit better than the ones at the lowest status. There were many poor relatives trying to seek help from the Rio Family, and Maggie's family was just one of them.
