Kaori Miyazono (宮園 かをり, Miyazono Kaori?) is the main female protagonist of Shigatsu wa Kimi no Uso. She was the only daughter of Ryouko Miyazono and Yoshiyuki Miyazono who was a free-spirited, gifted violinist whose playing style reflected on her wonderful personality.

She attended Sumiya Junior High School as a third year-student where she was in the same class as Tsubaki Sawabe. She first met Kousei Arima when she asked Tsubaki to set her up with Ryota Watari. As their friendship grew, she eventually began helping Kousei return to the piano world after his mother's death.
