In 1996 she married fellow composer Takayuki Iwai and would work with him in many future games. She also worked with Setsuo Yamamoto and Yuko Takehara. In 2000, Iwai left Capcom to form the sound unit Wavelink Zeal with her husband. She has since been involved with titles such as R-Type Final, Musashi: Samurai Legend, Twinkle Star Sprites: La Petite Princesse and R-Type Tactics. In 2007 the group was divided when Takayuki left to join developer Crafts & Meister, with Yuki handling all music composition duties. By 2013 Zeal was officially closed, though the two have since reformed under a new name: ZEAL★DoQMaL.
