Karma had for a long time been a rebellious student with a problematic attitude. However, due to his good grades, his homeroom teacher had supported him and proclaimed that "as long as you are in the right, sensei will be on your side".
One day he had found a senior from Class E being bullied and had jumped to his rescue, severely injuring his classmate in the process. Convinced that he was still in the 'right', he was shocked when his homeroom teacher told him that he was in the 'wrong'. The teacher then further elaborated that he had no right to protect a worthless piece of trash from Class E and instead injured a fellow student with a bright future. The teacher then told him that starting his 3rd year he would be dropped to Class E. This caused the teacher's worth to 'die' in Karma's eyes, also causing Karma to stop caring about teachers in general and instead focused on doing what he wanted.
