Unlike the other girls seen in Misao, Yoshino does not wear the full school uniform, just the white blouse and skirt. She wears some sort of yellow undershirt underneath and has a white headband in her short, pink hair. Her most common expression is a smirk with her fingers on her chin and her dark amber-colored eyes.

Yoshino was a mean-spirited girl who often bullied and picked on others that were weaker than her, Misao included.
She could come off as sarcastic, but her overall demeanor.
