Masayoshi Kimura

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

Appearance
Justice has dark brownish green hair which spikes up in many ridges ending in a triangular tip and black eyes.

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 earn him "Justice" as a name.Even if he doesn't like the name and asks them to change it.

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 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 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 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. 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, Kimura still hadn't lost the doubts about his name(rather spread it to the entire class). Korosensei mentions that he could change his name if he wanted to (due to he easily fulfills the requirements to change his name), but stated that "Justice" is 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.

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".

Abilities

Mobility: Kimura is considered one of the most adept students at free-running. He was part of the team responsible for distracting Karasuma-sensei during the game of cops and robbers.

Knifework: Kimura scored jointly 4th in the class (along with Hinata Okano, Megu Kataoka and Taiga Okajima) for Knife training from April to June.
