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".
