Hinata Okano

Hinata Okano (岡野 ひなた, Okano Hinata) is a student in class 3-E of Kunugigaoka Junior High School, taught by Korosensei.

Appearance
Hinata has short brown hair and brown eyes (light purple in the anime). Her hair is the shortest among all the girls in Class 3-E.

Personality
In her initial appearances, Okano was often shown to be serious with a relatively neutral expression. As the series goes on, she's later shown to also be playful in addition to being serious.

Plot
Like her classmates, Okano was introduced in Chapter 1 however, unlike many of her classmates, Okano has yet to be properly introduced. Instead she has steadily been gaining more and more appearances as the series goes on with her first being in Chapter 24 when she was shown handing a towel to Maehara after he had been kicked to the ground by Tomoya Seo. This introduced her as one of the more serious characters of Class E. Her more playful side was highlighted in Chapter 86 when she was shown smiling when telling one of Shiro's men that she was still frustrated from the game of Cops and Robbers back in Chapter 81 and Chapter 82 and proceeded to take him out.

Abilities
Knifework: Okano excels in knifework and is considered one of the two best out of all the girls in Class 3-E.

Okano has been noted for her agility which is attributed to her being a former member of the school's gymnastic club. She is one of, if not the most, physically agile student of Class E which she attributes to her fighting making her excel in close-range combat.

Kaede Kayano
It's possible that Hinata and Kaede have a close friendship, or at least get along really well due to the fact that Okano refers to her as "Kayanochii."

Hiroto Maehara
Hiroto and Hinata seem to have a good friendship and were paired up for Korosensei's Test of Courage and the Athletic Festival for the three-legged race. It's implied she has feelings for him.
