- Kōsei Arima
- is a former child prodigy in playing piano, dubbed the “Human Metronome” for his near-inhuman mechanical accuracy, a product of his mother’s overly strict methods of teaching. His ability to play the piano with unparalleled precision led him to win many competitions across Japan and even be invited to play abroad. When his mother died, the resulting psychological trauma caused him to be unable to hear the sound of his piano playing, and he gave up on it. Two years later, he takes up the piano again after being convinced by Kaori Miyazono to become her accompanist. Influenced by her emotional and unrestrained playing style, Kōsei eventually finds himself falling in love with her. He, however, does not confess his feelings due to her liking his best friend, Ryota Watari.
- It is later revealed in Shigatsu wa Kimi no Uso: Coda, a side story from Kōsei and Tsubaki’s childhood, that his inspiration for playing so beautifully in his first competition was to cheer up Tsubaki after the passing of her grandmother.
- Kaori Miyazono
- is Tsubaki’s classmate; she is a free-spirited violinist who has drawn much criticism from judging panels due to her unwillingness to adhere strictly to the score, but is highly favored by audiences that hear her playing. Kaori first met Kōsei when she asked Tsubaki to set her up with Watari. As their friendship grew, she eventually convinced Kōsei to play the piano again, first as her accompanist and later in a piano competition. It is revealed at the end of the anime, in a letter addressed to Kōsei, that she had asked to be set up with Watari in order to meet Kōsei, knowing that Watari and Tsubaki were good friends of his.
- Tsubaki Sawabe
- Kōsei’s childhood friend and next-door neighbor, who treats him like a little brother. She is athletic and is part of the softball club at school. Often dismayed at Kōsei’s inability to move on from his mother’s death, she attempts to get him to play the piano again in order to make a clear decision about his future. She first denies her feelings for him but after undergoing several stages of denial, she falls in love with him, which she confesses to him later on.
- Ryōta Watari
- is Kōsei’s and Tsubaki’s childhood friend, and is the captain of the school’s soccer team. He is extremely popular with girls, and usually adopts a frivolous attitude. However, he does come up with good insights every so often. Kaori was his love interest and when they are together, they are shown to be acting lovey-dovey, which makes Kōsei jealous. Kōsei later tells him about his feelings for Kaori, and he soon accepts this and gives him advice.
