Ursula Callistis, Little Witch Academia

A woman dressed in a witch costume, with blue hair and a pointed hat adorned with a yellow crescent moon. She is wearing a long-sleeved shirt with a pink skirt and a black belt around her waist. In her right hand, she holds a small black book or tablet, while her left arm rests on the back of an upholstered chair. The background of the image appears to be a library or study room, with bookshelves lining the walls and a few pieces of furniture scattered about. The overall atmosphere suggests that the woman is studying or reading in this quiet, academic setting.
