Adult female, slim 22-year-old Asian woman, wearing a Japanese school uniform (sailor fuku with a blue pleated skirt and white middy blouse), black Mary Jane shoes, and white knee-high socks. She has long black hair styled in twin tails with red ribbons, and she's carrying a backpack with math textbooks and a notebook. She's standing in front of a chalkboard covered in mathematical equations, with a slight blush on her cheeks and a gentle smile. The overall impression is one of youthful innocence and academic enthusiasm
