Cyntia

[1] They are believed to have been the first act from the Girls Metal Band Boom to have signed to a major record label when they joined Victor Entertainment in 2013.

[2] Drummer and co-founder Kanoko left the group in April 2015, and the band moved to the Village Again Association label for their 2016 album Urban Night.

[4] Their debut single, "Run to the Future", was released in April 2012 on Bright Star Records,[3] which was formed by fellow all-female metal band Aldious.

[8] They performed at that year's Naon no Yaon female-only rock festival and then opened for American metal band Kamelot on their Japanese tour.

Yui, Saki and Azu will reunite as Cyntia for one-night only at Club Citta on November 29, 2024, as part of the Queen of the Night two-man live with their former labelmates Aldious.
