Sasaki was born in
Fukuoka Prefecture on June 13, 1989. She began having an interest in music when, during her kindergarten years, her mother noticed that a classmate played the piano. Her mother then asked her if she wanted to learn how to play an instrument, and she replied that she wanted to play the violin. She played both the violin and the piano into her high school years, when she also learnt to play the guitar. While in high school, she became interested in joining a band. As her school only allowed bands during school festivals, she organized a band on such occasions. After graduating from high school, Sasaki took up studies at
Kyoto University, where she pursued a degree in
humanities. During this time, she joined a light music club and performed her first original song, which she sang for her seniors' band called FPS. She later formed her own band, which she named Lattice. While pursuing her graduate thesis, she tried writing songs in the hope that she would soon make her professional début. During her college years, she became increasingly interested in anime, particularly after watching the series
Steins;Gate and
Robotics;Notes. After finishing her graduation thesis, Sasaki learned of a competition to write a song for the anime series
Plastic Memories, which was written by Naotaka Hayashi, who also worked on
Steins;Gate and
Robotics;Notes. She participated in the competition, and although her submission was not chosen, she decided to audition instead to be the winning entry's singer. She passed the audition and was chosen to sing the series' opening theme "Ring of Fortune". Later that year, she made an appearance at
Animelo Summer Live. Sasaki's next release was her second single "Recalling/Last Diary", the title track of which was used as the opening theme to the 2016
