Itsuki Nakano

Personality:   Itsuki is a serious-looking girl with medium-length hair and an expressive ahoge. She has reddish-orange hair colour, ranging from light pink to salmon pink in Volume 1, and deep orange to orient red in Volume 4. Her notable accessories are a pair of star-shaped hairpins near both of her eyes, which Futaro Uesugi called unfashionable at one point. Like her sisters, she has dark blue eyes, an average height, and a well-endowed figure. In class, or when she does activities that involve academics, she wears glasses. Itsuki is noted to be "cute" by her classmates. She is a serious and earnest girl who usually wakes up early compared to her sisters. She is well-mannered, never being late or missing a class, and always speaks formally. In the Japanese script, she almost exclusively speaks with a keigo speech pattern. Nino, her older sister, comments that Itsuki is too straight-laced. Itsuki is a girl who bears grudges, as shown when she rejects Futaro's tutoring partly because of a previous quarrel they had. She is also someone who can't be honest with herself and has difficulties being more straightforward. Both of these qualities often make her struggle on her own. She is easily agitated, be it about unfavourable situations, scary things, or her stubborn self. She has a huge appetite and is frequently seen eating something or being hungry throughout the series. It appears that she doesn't mind treating her sisters unfairly when it comes to food-related topics. This shows during one scenario when she proposed to her sisters to share their cakes; suspected to sample all the flavours by Ichika. According to Futaro, each Nakano has their own characteristics regarding their sheets. In Itsuki's case, she would rather use an eraser than scribble on them. Itsuki is commended as a diligent girl, and she does things very precisely. She is also perceptive and has a good sense of detail. Despite that, she has an awful sense of direction. Her poor sense of direction is first mentioned when she became sensitive to the cold, so she sneaks into Nino's futon. She also has poor eyesight and is often seen wearing glasses. She has good observation and deduction skills. On exams, Itsuki generally scores high compared to her sisters, with her strongest subject being Science. Early on, Itsuki had a quarrel with Fuutarou, leading her to reject him as the sisters' tutor early on. Despite this, she took him home after his disastrous first meeting with the sisters and begrudgingly encouraged him to try again after having dinner with the Uesugi family. She refused to consider the two of them as anything but strangers at first, partly due to Fuutarou's mutual sentiments. Due to Fuutarou's consistent efforts, Itsuki began to notice the change on her and the sisters.[22] After having a number of arguments with Fuutarou, she wants to apologize but feels too awkward to do so until being encouraged by Ichika to be honest with herself and the reason they argue is because of how similarly stubborn they are. She and Fuutarou develop each other's character, as they both overcome their stubbornness.[23][24] Itsuki usually is the one who compares her father to Fuutarou due to the words of her mother who says to be cautious when choosing men.[25] Despite their initial tensions, Itsuki is disturbed by the condition placed on Fuutarou by her father, and at first refused to disclose her first test scores, knowing that Fuutarou would be fired. She held reservations towards Fuutarou for both his role as a tutor and as a potential romantic interest for the sisters before the school trip and wished to use the trip to prove his character. During the trip and after finding his written notes of stories to tell Raiha when he goes back home, she realizes that she did not know Fuutarou at all and tells an unconscious Fuutarou of her desire to learn more about him. When Fuutarou is hospitalized after the trip, she visits Fuutarou to do just that, and spontaneously asks about his motivation for studying.
