Karma comes from a wealthy family as his parents are successful financial day traders. They are "free people" who spend most of their time traveling around the world, and as a result, they spend little time with Karma. For a long time, Karma had 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 Karma does what's right, he'll back him up." In his first two years at Kunugigaoka Junior High School, Karma had been friends with fellow classmate Nagisa Shiota where he first approached Nagisa when he saw the latter reading an article about Karma's favorite film director adapting a comic book and invited Nagisa to watch with him. For a short time, the two hung out together with Karma being able to be less guarded with Nagisa. One day at a fast food outlet though, Nagisa unintentionally was able to sneak up on Karma. This made Karma feel exposed and vulnerable since Nagisa could have struck and killed him in that moment and he wouldn't have been able to react in time - something the strong and capable Karma wasn't used to. Karma sensed a mysterious but sinister feeling from Nagisa, but as he realized that he does not know how to deal with this (having being used to beating his problems with his fists). As a result, Karma distanced himself from Nagisa. By the time of his suspension, their relationship reverted back to being just classmates. One day Karma had found a senior from Class 3-E being bullied and had jumped to his rescue, severely injuring the main building's 3rd year in the process. Convinced that he was still in the 'right', Karma was shocked when his homeroom teacher told him that he was in the 'wrong'. His 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", and told him that starting his third year he would be dropped to Class E. This caused the teacher's worth to 'die' in Karma's eyes, as well as causing Karma to stop caring about teachers in general and instead focused on doing what he wanted.
