Personality[]
Kimura is one of the relatively proactive students when it comes to assassination and aims to claim the 10 billion yen reward.
Background[]
It is stated that both of his parents are police officers, and they have a high sense of justice, thus they named him "Justice". Even if he doesn't like the name and asks them to change it. He was constantly being teased about his first name being “Justice,” and his concentration dropped. As a result, his grades suffered and he was sent to Class E.
Story in Assassination Classroom[]
He is the main focus of chapter 89:Name Time. Although it is spelled with the general spelling for "Masayoshi", it actually reads as "Jasutisu" (a Japanese rendering of the English word Justice). He hates his own name because people would pick on him because of said name. Kirara Hazama also mentioned that she dislikes her name, while Karma mentions that he likes his. Korosensei then mentioned that Karasuma and Ms. Bitch both refused to say his name, resorting in them having a day which all of them used code names, and they are forbidden from using their real names for the rest of day.
At that point, a mock assassination is done with Mr. Karasuma as their target, in which everyone used code names to call each other. Once Chiba snipes Karasuma (in which he blocks with a piece of wood), they call upon Kimura to finish him off.
After the mock assassination, Kimura still had doubts about his name. Korosensei mentions that he could change his name if he wanted to, but stated that "Justice" was a better name if he happened to kill Korosensei later on. This makes Kimura think twice about changing his own name, at least until they happen to kill Korosensei.
