ソニア

A female knight of the Kingdom of Regalia. She is a rather talented swordsman and belongs to the elite royal guard.

She met Leen when they were children. She has always beaten Leen, or rather, Lean is no match for Sonia. Since Leen is weak, she does not respect him as much as she should.

As Leen becomes more influential by becoming the Count of Galicia, Queen Zamasu begins to impose her will on Sonia to do her bidding.
