Empress Fredia is Princess Vi's mother. She left home to travel the world. She and her daughter have a very unusual family dynamic—-they try to beat each other up when they first re-unite. She is Emperor Fred's wife. She only married him because he's rich.
If the series continued, the creators stated that she would have a flashback story of her meeting her husband when they were young. Unknown to her and her husband, her husband had a first born child before they met. When she found out, she would keep this a secret to make sure the throne belongs to her daughter which is ironic that Okara is keeping her heritage a secret to protect her and her family. Usa-no Tsubone would never know who the first born truly is.
Emperor Fred (husband)
