BiS, also known as Brand-new idol Society (Shinsei Idol Kenkyuukai, 新生アイドル研究会), 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.
