Parquets
Parquets (パーキッツ) is the duo of music composer Kataoka Tsugumi and lyricist/vocalist Fujino Manami. They have been producing songs for various anime and other projects since the early 1990s. In a rarity in Bemani, they have composed exclusively for pop'n music, and their music has never been transplanted into any other Bemani series.
Kataoka Tsugumi occasionally produces music without the help of his partner, usually under various names.
