After Gacharic Spin's original vocalist Armmy left to take a hiatus because of medical reasons, bassist and bandleaderF Chopper Koga decided not to cancel the planned tour dates, instead using an arrangement of supporting vocalists[5] including future Gacharic Spin member Oreo Reona, and Light Bringer's vocalist Fuki.[6] Due to Gacharic Spin and Light Bringer taking a break from live performances, they decided to form a new band, musically different from their current bands.[7]
The group's first studio album, Dolls Apartment, was released on December 12, 2012 in Japan.[citation needed] and January 29, 2013 in Korea.[citation needed] They released promotional videos for every song in the album (not including the cover song Nudierythm) on a weekly basis on their Niconico channel.[8] On August 27, 2014 they released a DVD collection of their music videos, Doll's Collection.
After an almost three-year hiatus, they reunited on February 25, 2017 for a triple-bill show with Gacharic Spin and Fuki Commune, and again on June 24, 2017 for Gacharic Spin tour finale where they premiered a new song and announced a new mini-album, High $pec.[9]
