She loves sweets and tries to exert her dignity as a Great Witch, but it usually backfires, making her look cute instead.

She takes great pride in her ability to do forward rolls. She is easily lured by sweets and cute things.

Hundreds of years ago, witches were wiped out by humans, and she held a grudge. However, over the centuries, she realized there are both good and bad people among humans and has forgiven them.
