2012-2014 – SISTERBONES

Backups dancers have a long history with BABYMETAL. They appeared in older “big shows”, especially for Black BABYMETAL songs, as the “SISTERBONES”.

Their first show was LEGEND D where they backed Head Banger (night of 15 mix). Then they appeared in LEGEND 1999, where they backed Yui and Moa in their solo songs. In LEGEND 1997 they backed Yui and Moa during Onedari Daisakusen and played a big part during Head Banger (Night of 15 mix) and BABYMETAL DEATH. Their last shows were at Budokan, where they backed Yui and Moa for Onedari Daisakusen and Song 4 again.


After that they didn’t have any backing dancers again until 2018, after Yui stopped appearing at shows. But these were different, as they no longer wore completely different outfits to the main members, but just slightly different outfits, and appeared throughout the entire show.

At least 1 of them appeared at every show in 2018. For the US and EU tour’s there were 2 (Minami and Minako), making a lineup of 4 with Su and Moa. Then, for the Japan tour, there were 5 (whole list below) making “The Chosen Seven”. Finally, for the last 4 shows of the year, Saya was the only backup dancer and basically filled in Yui’s position in the original 3 member lineup.
