Hinano Kurahashi

Hinano Kurahashi is a student in Korosensei's Class 3-E in Kunugigaoka Junior High School.

Appearance
Kurahashi has short, wavy orange hair and olive-brown eyes (peridot green in the anime). She has a more petite frame than most of the girls in Class 3-E.

Personality
Kurahashi's personality is best described as "yurufuwa" (a person who is warm, gentle, and relaxing). She is an energetic and positive girl and is always seen with a smile on face regardless of whether she's trying to assassinate Korosensei, or whatever else. She's an animal and nature lover as shown in Chapter 56. She was also noted to be a "reliable assistant" for the group of boys who are on the path to becoming "sleazebags." This stems from the fact that she has older siblings who are all boys and as a result can handle even the sleaziest talk. She is a very soothing and calming person and is described as being innocent and genuine. She is also good at making money, particularly being able to assess the price of the stag beetles she was hoping to capture and sell and at the end of the manga managing to get parents to pay her handsomely to take their kids on nature hikes.

Etymology
Kurahashi (倉橋): Kura (倉) means "warehouse" and Hashi (橋) means "bridge." Her surname is also the name of one of the 47 ronin of feudal Japan.

Hinano (陽菜乃): Hi (陽) means "sun" which may be a reference to her cheerful personality, Na (菜) means "vegetable" and No (乃) refers to the Japanese possessive particle "no" (の).

Plot
Like the majority of Class 3-E, Kurahashi debuted in Chapter 1; however, she wasn't properly introduced until Chapter 56. In Chapter 56, she revealed to be good at biology as she held knowledge on what types of beetles would be in more demand and which ones wouldn't.

Seven years after the graduation and assassination of Korosensei, Kurahashi makes an income by conducting nature adventures for kids using the Class E mountain.
