Kaori Miyazono is one of the main protagonists of Shigatsu wa Kimi no Uso. She is a violinist who helps Kousei Arima return to the piano world after his mother's death. Kaori Miyazono is a free-spirited violinist whose playing style reflects on her personality. She is independent, unpredictable, and short-tempered. It is also touched upon that she is passive aggressive at times. Kaori likes to depend on herself and only herself and can be seen as more of a support for others. While considered a really sloppy violin player from a technical standpoint, such as not following music score sheets the way they are written, Kaori is an amazing violinist. Noted by one of the judges at Towa Hall during the first competition of the series, her pure abilities far exceed the others in the competition. She wields a free spirited style of performance that emphasizes emotions and artistry over the pure mechanics of music, such playing to specific tempos and dynamics originally intended by the composer. Her style of music is what rekindles Kousei's passion for the piano and inspires him to redefine himself as a musician. In addition, she has the ability to play the melodica and has had some experience playing the piano. (Source: Shigatsu wa Kimi no Uso Wikia)

However, after being accepted into UA and facing Katsuki during Battle Training, he has gradually become more confident and brave. Izuku is also very diligent and strong willed. Since he greatly admires Heroes and has always aimed to be one, he has a habit of writing down in his notebooks all he knows about heroes and their quirks, including other UA students. He is a very caring person, and will never hesitate to rescue someone in danger, even if he knows he's not strong enough. When someone has a personal problem, Izuku will always try to help, even if it's not his business.
