Hiroko is Kousei's piano mentor, guardian, and formerly a close friend of Saki Arima. Hiroko is also a renowned pianist in Japan and was also seen taking care of Saki before her death. Hiroko is a tall, beautiful and athletically framed woman with straight shoulder-length black hair that has a single strand hanging in front of her face swept to the left and navy blue eyes. Before the death of Saki Arima (Hiroko's close friend), Hiroko had mid-back length hair and a thicker fringe. Upbeat and exuberant on the outside, Hiroko is actually a warm-hearted and sensitive person who cares for Kousei Arima after he decides to begin to play the piano once again. She also partly feels guilty for pushing Saki Arima to make Kousei into a pianist, pushing him into a corner. But all in all, she supports him in all his decisions and is always there for him.
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.
