Yoshino is a mean-spirited girl who often bullies and picks on others that were weaker than her, Misao included. She could come off as sarcastic, but her overall demeanor was that of a typical bully: intimidating and pushy. Her bullying has even escalated to more offensive acts that resulted in Misao's trauma and depression/self-loathing although she considered her bullying as just a little teasing and playing when called out by her classmate, Tohma.
