April 6, 2005 saw the release of "Juusankai wa Gekkou" which also happened to be the band's fourteenth studio album. It was a concept album inspired by Sakurai's solo project that focused on the idea of "Goth", and despite the residual gothic image Buck-Tick had been cultivating for years, it was a significant departure from any of their previous work. Special care was taken with the sets and costumes for the tour. The live shows were very dramatic, and the band even hired a clown (Gaetano Totarou) and a ballerina (Becky Janik) to perform with them at some of the shows. At this time, visual kei and Gothic & Lolita had been growing significantly in popularity and with "Juusankai wa Gekkou", Buck-Tick gained a large number of new fans domestically and overseas who admired the gothic style.
