Nagi Aiza

Nagi is a supporting character in Your Lie in April. She is the younger sister of Takeshi Aiza, and is a Year 7 student at Kurumi-Gaoka High School. Nagi is a piano student of Kōsuke Oka. Nagi is characterised by her blond pigtails and golden brown eyes, often seen wearing her school uniform. She is described as very cute and pretty. In her early teens, she has yet to develop a woman's body and height. She establishes the cute little sister character in the story. Hiroko Seto also commented that she looked a lot like her brother because of her hair. Nagi is stubborn and somewhat childish. She is also cunning, and hard-headed. Nagi maintains a realistic look in life and repeatedly testifies her hate for cliché. Because of her unerring piano skills, she is slightly arrogant and claims herself as the "Angel of Kurumi Junior High". Nagi also appears to have a distaste for anyone who refers to their superiors without the appropriate honorific, as shown when Miike did not refer to Kousei Arima as his Sensei or Senpai, instead addressing him directly as "Arima". When she was younger, she saw her elder brother as some sort of hero. They often played together and had a close relationship, but Takeshi started to fix on Kousei Arima. Because of that, he started to practice hard and the strong bond between the two became thinner over the years. In order to be closer to her brother and gain his attention, Nagi started to play the piano. She began majoring in music in her first year at Kurumi-Gaoka Junior High School.
