Kawamoto was one of the first musicians hired at Capcom. In 1989, she joined
Taito as a composer, becoming a member of their
house band and sound team,
Zuntata. While in Zuntata, Kawamoto composed the soundtracks for
Yūyu no Quiz de Go! Go! and the
Ray series, including
RayForce,
RayStorm, and
RayCrisis. According to Kawamoto in an interview, shortly after she left Zuntata, a prior coworker that was still working at Zuntata invited her to a party where they introduced her to the singer Cyua. Kawamoto later joined up with Cyua to form the group Betta Flash, with Kawamoto composing their songs and Cyua being the vocalist. Betta Flash's single, Erinyes, is featured as the closing song in the anime
Night Wizard!. Betta Flash also arranged new songs for the CD set, "Ray'z Music Chronology," which was released in 2017. == Music credits ==
