BiSH (ビッシュ), also known as Brand-new idol SHiT (Shinsei Kuso Idol, 新生クソアイドル), is a Japanese idol group under WACK that was founded in 2015.

The group was conceived as a successor to BiS, whose first generation had disbanded the previous year. However, they since developed their own identity, especially after BiS was rebooted.

They are often described as being "a punk band without instruments".

In March, Yukako Love Deluxe, Cent Chihiro Chittiii, Hug Me, Momoko Gumi Company and Aina The End were announced as members of BiSH. The members' faces were obscured with black contact lenses and could not be revealed until they each attained 4,444 followers on Twitter.

Not long after Spark's release, Yuka withdrew from the group due to anxiety. In April, BiSH released a music video for the song BiSH: Hoshi ga Matataku Yoru ni, and more songs were released for free in the lead-up to the release of their debut album, Brand-new idol SHiT, on May 27th.

On August 5th, Hashiyasume Atsuko and Lingling were announced as new members. Like the previous generation, their faces were obscured with contact lenses until they received more Twitter followers than Watanabe.
