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.

Abilities
Knifework: She is 3rd best ranked student in knifework along with Rinka Hayami and Toka Yada on the girls side.

Biology: Kurahashi has extensive knowledge in Biology as noted by Nagisa and has even been shown to be able to interact with dolphins during the Summer Vacation arc.

Irina Jelavić
Along with Yada, she's one of Irina's favorite students. They are the only the students who know about Irina's past and true personality. During the Valentine's day arc, she declares a war of affection against Irina that she will steal Karasuma from her, much to Irina's confusion.

Tōka Yada
Yada and Kurahashi are close friends and as a result, are frequently seen together. A notable example was during an effort to infiltrate Japan's space station, they distracted the guards by pretending they were lost.

Taiga Okajima
Kurahashi and Okajima share a prominent introduction in Chapter 56 and were paired together during Korosensei's "Assassination Test of Courage".

Tadaomi Karasuma
Kurahashi is the student who attempts to interact with Karasuma the most, as she has a crush on him.

Rio Nakamura
Though they aren’t often seen together, the two of them have bonded over bejeweling their knife sheaths. The two of them also seem to have their airheaded moments together, as they casually were showing them off during a school assembly, much to Karasuma’s dismay.

When Hinano tells the girls that she has a crush on Karasuma, Rio remarks by telling her no girl in 3-E does not have a thing for him. The two are also shown battling each other with knives during one of 3-E’s PE lessons before Takaoka’s arrival.
