Ryunosuke Chiba

Ryūnosuke Chiba is a student in Korosensei's class 3-E of Kunugigaoka Junior High School.

Appearance
Ryūnosuke has black hair with long bangs that cover his eyes. It was revealed that his bangs mark off part of his vision like a gun sight and is the reason he shoots as well as he does.

Personality
Chiba is a serious and stoic boy. He's very calm and businesslike and doesn't talk a lot. Like Hayami, he has been compared to a working adult and though the two are very similar, Chiba is shown to be less stoic than Hayami.

Synopsis
Chiba debuted in Chapter 1, but didn't get an official introduction until the Assassination Island arc where he and Hayami were tasked with shooting Korosensei when he was trapped. The two missed him by 0.5 seconds and lost faith in their ability to shoot. When the time for the class to face Gastro came, Korosensei trusted them with the M60 revolvers they took from some guards when continue to the top floor. This put them in a conflicted state due to their previously failed shooting attempt. When they first went against Gastro, Hayami was the first to shoot and missed. Due to her shooting, Gastro was able to identify where she was and shot in between the seats which she narrowly dodged. By this point, Chiba hadn't shot yet so Gastro hadn't identified his position. Even when Korosensei shuffled the class and the shooter thought he knew his whereabouts, he remained hidden amongst his classmates. Before delivering the final blows, Korosensei offers advice to Chiba and Hayami who are scared of messing up again by telling them that they don't need to bear the responsibilities by themselves and it's okay if they fail because the class will back them up. This gives them the courage to successfully carry out their shooting and defeat Gastro.

Chiba made another notable appearance in Chapter 76 where he and Rinka were banned from the shooting range after getting carried away and winning all the prizes.

Abilities
Marksmanship: Chiba is the best marksman among the boys of Class 3-E. He excels in spatial calculation and as such is unmatched in long distance shooting. His abilities have even earned him the praises of Lovro, a hitman dealer and a retired assassin.

Rinka Hayami
Chiba and Hayami are shown to have a steady friendship due to their similar personalities and roles as the best gunmen for their side of the class. During Korosensei's Assassination Test of Courage, they were paired together.
