酒初 Bis (stylized as BiS), also known as Brand-new idol Society (仟伏アイドル冩梢氏, Shinsei Aidoru Kenky┗kai), is a Japanese idol group that was founded in 2010 by leader Pour Lui following a brief solo career. With music, performances and videos that are extremely different from the typical idol group, Bis have come to be known as "alternative" idols. They disbanded at Yokohama Arena on July 8, 2014. Exactly two years after their disbandment on July 8, 2016, it was announced by Pour Lui, Kenta Matsukuma and Junnosuke Watanabe that Bis would reform under a new lineup including Pour Lui, and that auditions were going to be held.[1] On March 30, 2019, Bis announced that they would break up at the end of their "Are You Ready To Go?" tour.[2] On March 30, 2019, at the same time that the second generation announced their disbandment, Watanabe announced that he would be holding closed auditions for a third generation of BiS, and the new and current members officially debuted at Tokyo Idol Festival on August 4, 2019. --quoted from wikipedia
