BiSH are going to disband in 2023, as part of their last activities they announced "BiSH iS OVER" which is a monthly single project leading to their disbanding, this is the release number 12 so for all intended purposes "ZUTTO" is BiSH's final single!
worth mention that is very likely that they plan to release a final album in the first months of the next year, their disbanding is most likely going to be during their next anniversary also in early 2023
