Masayoshi Kimura

Justice "Masayoshi" Kimura is a student in Korosensei's Class 3-E in Kunugigaoka Junior High School.

Background
It is stated that both of his parents are police officers, and they have a high sense of justice, thus earn him "Justice" as a name.

Personality
Kimura is one of the relatively proactive students when it comes to assassination and aims to claim the 10 billion yen reward.

Plot
He is the main focus of chapter 89:Name Time. Although it is spelled with the general spelling for "Masayoshi", it actually reads as "Seigi" (which means Justice). He hate his own name because people would pick him because of said name. Kirara Hazama also mentioned that she dislikes her name, while Karma Akabane mentions that he likes his. Korosensei then mentioned that Tadaomi Karasuma and Irina Jelavić both refused to say his name, resorting in them having a day which all of them used code names, and they are forbid from using their real name for the rest of day.

As then, a mock assassination is done with Mr Karasuma as their target, in which everyone used code names to call each other. As Eroge Protagonist snipes Karasuma (in which he blocks with a piece of wood), they call his code name; Justice, to sneak attack Karasuma from behind to finish him off.

After the mock assassination, while Kimura still have doubts in his name, Korosensei mentioned that he could change his name if he wanted to (due to he easily fulfill the requirement to change his name), but stated that "Justice" is a better name if he happened to kill Korosensei later on, makes him think twice about changing his own name, at least until they happen to kill Korosensei.

Then Korosensei suggested his own codename, "The Imperial Prince of Fate of the Eternal Wind", which makes everyone very irritated, and proceed to call him "Stupid Pervert Chicken Octopus".
