Wednesday Campanella was formed in 2013 featuring KOM_I as their main performer / lead singer. Members included KOM_I (main vocals), Kenmochi Hidefumi (music), Dir.F (all other responsibilities), but KOM_I was the only one to be making public appearances. On 6 September 2021, KOM_I left the group, and Utaha joined them as their new lead singer. In the same year, on 27 October, their first song from the newly formed group called “Alice/Buckingham” was released. On 25 May 2022, their first EP with Utaha called “Neon” was put out. The following month, they embarked on their first nationwide tour entitled “Wednesday Campanella Joint Tour - 2022 ~Neo poem~”, and on 3 August, they held their first solo live concert in Ebisu Liquidroom. All the dates of this Japan tour were sold out.
