In Summer 2010 Suu and Hinanchu, both models for "CUTiE" magazine at that time, met in between shots and share their love for music. The band was formed when Hinanchu invited her friends Ainyan and Yana to met Suu. They performed their first live in October 2011 at the AGESTOCK2011 in TOKYO DOME CITY HALL event. Four months later, in February 2012, the band debuted under the indies label Brand-New Music with the mini-album Saisai, an acronym for Silent Siren.
