At eight in the morning on 24 December 2021, BiSH streamed a surprise show, free and live, on their official YouTube channel from heavysick ZERO — a black-walled basement room in Nakano, Tokyo that holds barely a couple of hundred people. It is where the group played their first headline concert, "THiS is FOR BiS", on 31 May 2015; the new title changes a single letter. Aina The End, Cent Chihiro Chittiii, Momoko Gumi Company, Hashiyasume Atsuko, Lingling and Ayuni D arrive in black pinstripe suits, standing on the floor among a few dozen masked fans, and open by singing "BiSH -Hoshi ga Matataku Yoru ni-" three times in a row, the way they once had to when they barely had a setlist. Sixteen songs follow, almost all of them early ones. Then, in the last MC, Cent Chihiro tells the room and everyone watching that BiSH will disband in 2023, and reads out four promises for the year ahead. An ending announced on Christmas Eve, in the smallest room they know.
