Origin
Japan
Saki was the wife of Takahiko Arima and the mother of Kousei Arima. She was a well-known pianist across Japan before her death, which severely affected Kousei's playing style for the next two years, because of the way she treated Kousei in his past. Saki has shoulder-length brown hair and dark eyes. She was either depicted with no eyes at all or she has brown eyes. In some parts, she is seen with nasal canulla used to deliver supplemental oxygen for her illness and she is usually seen sitting in a wheelchair. Although Saki was strict and harsh towards Kousei Arima, she did care dearly for him. Before her death, she was shown to fret over whether Kousei would get hurt or manage to make a living.

Your Lie in April
Music accompanies the path of the human metronome, the prodigious pianist Kousei Arima. But after the passing of his mother, Saki Arima, Kousei falls into a downward spiral, rendering him unable to hear the sound of his own piano. Two years later, Kousei still avoids the piano, leaving behind his admirers and rivals, and lives a colorless life alongside his friends Tsubaki Sawabe and Ryouta Watari. However, everything changes when he meets a beautiful violinist, Kaori Miyazono, who stirs up his world and sets him on a journey to face music again. Based on the manga series of the same name, Shigatsu wa Kimi no Uso approaches the story of Kousei's recovery as he discovers that music is more than playing each note perfectly, and a single melody can bring in the fresh spring air of April.
