A male-female twin vocal unit consisting of Sachi and Miccino. The two met at Tokyo College of Music and performed together since their school days, and after graduation, they formed a music unit and toured Tokyo and other parts of Japan to give concerts. The harmonies of Sachi’s singing voice, which she cultivated as an opera-singer in Miccino, and Hibiki’s JAZZ and POP, which she worked on after graduating from music college, add a sense of glamour to the hall.
