Shin Sawada

Shin is the leader of class 3-D. He is cool, level-headed, smart, and somewhat introverted. Everyone in the class looks up to him. Shin is feared because of an incident back in middle school, where he punched out a teacher who constantly persecuted a student he believed to have committed a crime, where later he was proven innocent the teacher refused to apologize.

Shin knows right away that something is not normal about their new teacher and keeps an eye on her. He's the first one to find out Yankumi's true identity. In the manga, he is given the alias of "Young Master Red Lion" from Kyou. Shin's father is a high ranking police official.
