BiS Kaidan is a collaboration between BiS/ＢｉＳ (Brand-new idol Society) and Hijokaidan (非常階段).

Naked, viscera exposed, covered in blood, holding trademark spiked bats, performing live in swimsuits, holding 24-hour concerts, auctioning themselves online as maids… The alternative idol group, BiS, go beyond the ready-made perception for the typical idol group and are famous for their wild performance.
Hijokaidan formed in 1979 and has been revered as the first noise band and a legendary band for quarter of a century as the noisiest and the most improvised band in the world.
The miracle encounter of these 2 brilliant bands took place in Yotsuya Outbreak in November 2012 at an event called "Jika Hatsuden vol.00".
