They were a parody of BILLIE IDLE®︎ and considered to be their rivals.
The group initially briefly appeared at the end of the music video for "Soshite, Mata..." Just a few days later, an alternative music video was released with BULLY IDOL performing and BILLIE IDLE®︎ having a short cameo at the end. This version of the song was titled Soshite, Mata... (Remix).
On April 9, advertisements for an untitled Bully Idol release scheduled for the following day started to appear in record stores. The following day, BULLY IDOL's version of Soshite, Mata... was released.
They held their debut live on May 31. After this live, Soshite, Mata..'s promotions ended and the group became inactive. As BILLIE IDLE®︎ disbanded on December 28, BULLY IDOL has also been presumed disbanded.
