Bianca is an almighty witch of witches, like a great role model. While waiting for people to live in peace with witches, Bianca still chose to live in the Black Forest because many people still discriminated against witches. She is very talented and smart, can do almost anything but in return, the price to hire her is very high. Sometimes it's not just money, or it takes a lot of searching to deal with Bianca, a lady with high ambition and greed.
