Six talented singers and voice actresses formed i☆Ris in 2012, each taking an identity from a colour of the rainbow. After testing pop's waters with a series of singles they unleashed debut We Are i☆Ris!!! in 2015. Saki Yamakita's beautiful lead vocals front a technicolour and endearing brand of J-pop, with sweet group harmonies chiming over ultra-danceable, synthetic beats balanced by scattered, earthier rock guitar breaks that add some bite. With songs infused with almost boundless optimism and joy—and several popular anime themes in the bag—this idol group's popularity is assured.
