Rio Nakamura

Rio Nakamura is a junior high student studying in class 3-E of Kunugigaoka Junior High School.

Appearance
She has long, straight orange hair. In fact, she is one of the 2 students with orange hair, the other one being Kurahashi Hinano whom she is seen quite regularly with.

Personality
She is a very individualistic girl and an opportunist. She is seated between Shiota Nagisa and Nimura Kouki. Her seat is located behind Okano Hinata and in front of Hayami Rinka. She seems to get along quite well with her classmates.

Plot
She is first seen when the entire class attempts to assassinate Korosensei under Nagisa's command. Later she is seen cheering Nagisa on along with the other classmates when Nagisa goes up to Korosensei with an assassination attempt. She and the rest of class 3-E sees through Irina Jelavic's sweet-talking when she is introduced to the class as a part-time foreign language teacher and like everyone else, finds Irina to be a detestable person. She's annoyed when Irina makes the whole class bite down their bottom lip because they pronounce the "V" in "Jelavic" as "B" thus making "Vic" sound like the word "Bitch". Rio as well as the rest of class 3-E also chases Irina out after she insults them by saying that even if they start studying now its meaningless because they are misfits of the school. She seems rather interested in the notion of having a conversation with a foreigner (for example Captain Jack Sparrow) and warms up to her slightly after she apologizes to the students of class 3-E and starts taking her job as a teacher more seriously. She is shown to have a more girly side such as when she and Hinano decorate their knife sheathes and shows them off to Karasuma-sensei during the school assembly (Chapter 11). She's also somewhat opportunistic as seen when Korosensei wore himself out from making too many duplicates she wondered whether they should use the opportunity to assassinate him. She didnt think much of studying and felt that after assassinating Korosensei, even if her results are bad she can still live a comfortable life, she later changes this way of thinking. During the school trip to Kyoto she is in Group 2 which consisted of her, Mimura Kouki, Taiga Okajima, Ryūnosuke Chiba, Hayami Rinka, Yuzuki Fuwa, and Sugaya Sōsuke. Group 2's goal was to have Korosensei be fully engrossed in a samurai show so that Red Eye has a chance to assaSsinate him. However, that plan was a failure after Korosensei joined in the samurai show and ended up bocoming one of the lead actors. She is rather perverted as shown at the inn in Kyoto, she shocks Okajima when he catches her trying to peep on Korosensei taking a bath. This was done out of curiosity as to what he looked like under his clothes since he has such an unusual appearence leading to Okajima commenting that he couldn't believe such "unsexy" peeping existed. She blocks the exit of men's bath saying that even if they didn't succeed in killing Korosensei they could at least see him naked. She and the rest of the girls attempts to assassinate Korosensei after he tries to slip into their "women's gathering" while Irina was about to tell them a racy story of her experience in love when she was 17. She and her classmates were annoyed when Ritsu disturbs the class by firing BB pallettes the entire day in order to increase her chances of killing Korosensei. In the retailation plan aimed towards Tomoya Seo and Tsuchiya Kaho for humiliating Maehara Hiroto, she was one of the snipers that shot the laxative made by Okuda Manami from the window of a building opposite the tea shop Tomoya Seo and Tsuchiya Kaho were seated at. She and the rest of the girls from 3-E cheers for the boys during the baseball match against Sugino Tomohito's old baseball teammates. She is impressed by Sugaya Sosuke's henna painting skills and comments that the way he draws it with a piping bag is like drawing with melted chocolate. Later she sports henna tattoos on both arms courtesy of Sugaya. When Takaoka Akira first joins them as their new P.E teacher and training instructor, she enjoys the sweets bought by him but like her classmates she comes to hate and fear him and his violent training method. She and the rest of the class is shocked when Karasuma chooses Nagisa as the person who will defeat Takaoka. She doubts him because of his small and rather petite built as well as his lack in physical strength and worries for his safety. Later on she and the rest of her classmates are releived when Nagisa succeeds in defeating Takaoka, even cheekily stating that Nagisa was a real carnivore despite appearences. Later she and Hinano tries to get Karasuma-sensei to go out for snacks with them saying that it was thanks to them he can continue on as their P.E teacher (though it was really thanks to Nagisa). While enjoying the pool created by Korosensei for their personal use, she and Fuwa Yuzuki expresses slight surprise at the fact that Nagisa was "really a guy" since it was hard to tell. She and the rest of her classmates also found themselves slightly annoyed at Korosensei's fussiness when it comes to poolside manners. She and a few other students show their displeasure at Terasaka Ryōma for destroying Korosensei's wooden replica of a large motorbike. Nakamura and the rest of her classmates (excluding Terasaka and Akabane Karma) were swept off after Shiro destroys the dam though they were later saved by Korosensei. It seems she, Kataoka Megu and many of their classmates holds a small grudge against Karma for always devising plans and getting the most credit for them because of his cunning and calculating mind yet most of (if not all of) the dirty work is done by other students and joined in with splashing Karma with water after Terasaka pulls him into the pool. She is shown to be good in the English subject and previously ranked 11th overall though later with a little effort she manages to up her rank to 1st place. When insulted by the "Five Virtuosos" who jokingly said they will stake their lives on the upcoming examination, she stabs at Koyama Natsuhiko with a ruler which he narrowly misses. While making their way to the examination room, two students from the main building jeers at her and Nagisa for making a bet against class A even though they were from class E, she stabs the nostrils of one of the students with two pointed pencils, one which broke in the process. She and Nagisa meets Ritsu's representative in the exam room and shows admiration towards Karasuma who manage to endure the mocking gaze of the chairman while getting him to agree to a representative for Ritsu.
