Yoshino Kazuki

Yoshino was the leader of the bullies in Aki's/Akito's and Misao's school. She can be considered a minor/supporting character in the game, but she was a major player in Misao's disappearance and eventual death. Before and during the events of the game, 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 was that of a typical bully: intimidating and pushy. However, her acts of bullying eventually escalated into outright cruelty, to the point where she coerced a male student to rape Misao in a bathroom stall. In Truth, it's revealed that Yoshino had learned that Misao had a crush on Tohma. Yoshino herself had a crush on Tohma and her feelings of jealousy were what caused her to start tormenting Misao. She can also be noted as a gossip during the initial conversation at the beginning of the game, talking to the others about the strange things happening at school after Misao's disappearance.
