Rinka Hayami

Rinka Hayami is a student in Korosensei's class 3-E in Kunugigaoka Junior High School.

Appearance
Rinka has medium-length wavy light brown hair and brown eyes (depicted as orange-brown and green in the anime respectively). In her early appearances she wore her hair down, but from Chapter 35 onward, she began wearing them in low pigtails. In the anime, her low pigtails have been worn since her initial appearances.

Personality
Hayami is a serious girl who stood out for her marksmanship. She's very stoic, businesslike, and professional and has been compared to a working adult along with Chiba. She's quiet and calm and has been shown to be straight-forward.

In her initial appearances Hayami was shown with a much more mild personality, conversing and even smiling with other students. It is presumed that as she gradually started to appear more and more in the manga, her personality shifted to being more cold and serious where as in the anime she was always cold and serious.

History
Hayami fell into Class 3-E due to others depending on her too much. She didn't voice any disapproval and as result, this left her little space to focus on her studies which ultimately dropped her into Class E.

Plot
Rinka was introduced in Chapter 1 along with the majority of her class, but didn't get a proper introduction until the Assassination Island arc where she and Chiba 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 go against Gastro, Hayami aims for the gun in his hand but missed. By her shooting, Gastro was able to identify her position and shot in-between the seats, narrowly missing her. This prompted Korosensei to step up and shuffle up the students, confusing Gastro. 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.

Rinka made a notable appearance again in Chapter 76 where she and Chiba were banned from the shooting range after getting carried away and practically robbing the stand of its prizes.

Abilities
Marksmanship: Hayami is the best marksman among all the girls of Class 3-E (and third best in the class), scoring 101/200 in a test in June.. She has a good balance of accuracy in her fingers and good kinetic vision and is said to be an excellent soldier capable of taking down any moving target. Her abilities have even earned her the praises of Lovro, a hitman dealer and a retired assassin. In chapter 146 she demonstrates she can fire accurately even from difficult positions such as hanging upside down from a tree.

Knifework: Hayami is scored joint third for knifework with Hinano Kurahashi and Toka Yada.

Ryūnosuke Chiba
Hayami and Chiba 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 "Nuru-nuru Assassination Test of Courage", they were paired together. According to the official character book, Hayami and Chiba have gone on dates and are presumably dating. It was also stated that she talks more when she's alone with him.
