Plot

Kōsei Arima is a piano prodigy who has won many awards due to his precision, timing, and ability to switch between tempos easily, earning him the moniker "the human metronome". He achieved so much because he was meticulously taught by his terminally ill mother, Saki, who was abusive and demanding. When, as a seven-year-old, she slapped him after a victory that she deemed unwarranted, he declared his refusal to play the piano ever again and wished that she died. Indeed, Saki died the following day; this caused Kōsei to experience a mental breakdown during a recital, making him unable to hear sounds from the piano. Since then, Kōsei quit playing piano in public.
